How to get rid of malfunctions of the Ural walk-behind tractor?

These units, like any other equipment, even with proper care, can periodically fail.
Therefore, you should not panic, but use the information provided in the operating instructions that come with the walk-behind tractor itself. Since the Ural walk-behind tractor is a fairly simple and understandable device, it will not be difficult for a person even without much experience in this matter to carry out all the necessary work.

• What to do if gasoline does not flow into the carburetor? Often the cause of the malfunction lies in a clogged faucet of the sump filter. To get rid of it, it is advisable to clean the specified part;
• What to do if there is very little compression in the cylinder? It is necessary to rid the fungus of excess carbon and rub it into the cylinder body;
• What to do if the engine smokes a lot? It is advisable to open the air damper completely;
• What should you do if you hear knocking noises in the combustion chamber? It is worth replacing gasoline with a higher quality one, ridding the chamber of carbon deposits and unloading the engine as much as possible;
• What to do if gases break through between the cylinder head and body? You need to buy and install a new gasket, because the old one is completely bent;
• What to do if the spark plug electrodes are almost burnt out? Replace them with new ones.

Naturally, these problems are not the only ones that can arise during the operation of Ural walk-behind tractors, but they are the most common. The diagrams below will help you understand the specifics of the design and perform all the necessary procedures correctly. The Ural walk-behind tractor is clear proof that old does not mean poor quality or unusable. Classic walk-behind tractors are the first, but at the same time, they still perform their basic work efficiently and are distinguished by reliable material that can withstand various negative factors for more than 20 decades.

Ural with UMZ-5V engine

The engine of the Ural UMZ-5V walk-behind tractor is a 4-stroke, 1-cylinder gasoline unit with a volume of 475 cm³. The motor was originally created for use on self-propelled agricultural machinery and stationary installations. The power unit develops a power of 4.5 liters. With. at 2000 rpm. The plant allows a short-term increase in power up to 5 hp. With. by increasing the speed.

Long-term operation at high power is not allowed, as it leads to overheating.

The engine is equipped with an air cooling system. To cool the engine, a fan is used that forces air into a casing located around the cylinder and head. When operating a walk-behind tractor, it is necessary to regularly inspect and clean the cooling fins from dust and oil. Accumulated dust impairs heat transfer and causes local overheating, which leads to increased engine wear.

The motor is equipped with an automatic speed controller. For this, a centrifugal mechanism is used, which does not allow a rotation speed of more than 2350 rpm. When the speed is exceeded, the throttle valve shifts, which leads to a drop in rotation speed. The engine manufacturer prohibits self-adjustment of the rev limiter, as well as its use to control the speed.

The gas distribution system consists of 2 lower valves. Because of this, the engine has a low compression ratio of 6 units. The engine uses automobile gasoline A-76 (A-80) as fuel. The fuel supply is located in a tank located above the engine carburetor; the liquid is supplied by gravity. The fuel reserve in the tank is 6 liters, which provides an operating time of up to 4-4.5 hours. Operating time depends on the condition of the engine and the nature of the tasks performed.

The engine of the Ural walk-behind tractor is equipped with a 2-speed gearbox with reduction gears. The first speed reduces the rotation speed by 6 times and is used to perform work with a high coefficient of resistance (for example, plowing virgin soil). The second speed reduces the speed by 2.91 times and is used for operating the product with a trailer or when plowing soft soil. Switching the speeds of the UMB-K Ural walk-behind tractor according to the instructions is carried out with the engine not running.

The engine is started with a cord that is wound around the flywheel. Before starting, it is necessary to set the crankshaft to the compression end position. Starting the engine is permitted in 1st or 2nd gear of the motor gearbox.

The engine output shaft is equipped with a 2-ribbed pulley designed to transmit torque to an additional gearbox and to drive attachments. On the fan side there is a second pulley used to drive attachments that require increased rotation speed of the working parts. The clutch mechanism consists of belts and tension rollers.

According to the repair instructions, the transmission crankcase of a walk-behind tractor with a UMZ-5V engine is filled with 1.5 liters of transmission oil. The substance is poured through a hole closed with a plastic stopper.

The standard set of attachments for the walk-behind tractor included a cultivator. To transport cargo weighing up to 350 kg, a 2-wheel TOP-350/350M trolley was used. When using a single-body plow, the installation of an adapter device is required, which is attached to the frame. The plow can be used in conjunction with metal wheels equipped with lugs. A mounted potato digger is used in conjunction with a plow.

Motoblock Ural UMZ-5B

The model is equipped with a four-stroke single-cylinder engine. It is cooled by force using air flow. The working volume of the cylinder is 520 cm3. The motor power (4.5 hp) made it possible to perform many useful tasks, and the weight of the device was so great that the need to use a weighting agent completely disappeared.

According to reviews from owners, at maximum load fuel consumption reached 1.5 liters. Often the launch took place using a starting handle or a special cord.

Specifications:

• Piston stroke – 90 mm;
• Lubrication system - splashing;
• Oil sump capacity – 1.5 l;
• The oil temperature does not rise above 30°.

Operating instructions for the Ural UMZ-5B walk-behind tractor engine

The unit is known for its resistance to various mechanical factors and the possibility of prompt repair. The operating instructions and special photos showing the specific design of the engine and regulator will help you understand all the intricacies of this process.

Often Ural walk-behind tractors were sold with Chinese engines, but such modifications significantly increased the cost of the device, so ordinary people gave preference to domestic components (with a ZID engine), realizing that in case of problems, repair work would not be difficult.

Ural with ZiD engine

Small batches of walk-behind tractors were equipped with a ZiD-4.5 power unit. The design of the motor is not very different from the UMZ-5V. The crankshaft contains a pulley and a sprocket for driving the chain. The pulley is located on the flywheel side, the chain drive is located on the gearbox side. The chain drive is used to drive stationary installations. The engine is lubricated by splashing; oil is supplied by a plunger pump from a sump that holds 1.5 liters of liquid.

A belt drive is used to transmit torque from the engine to the transmission. The belt for the walk-behind tractor has a size of 1120*17*11 mm. The walk-behind tractor uses a 2-speed transmission, the design and control of which are similar to machines with a UMZ-5V engine. The gearbox has 2 speeds, reducing the rotation speed by 17 and 7 times, respectively. The gears are changed using a handle. Before starting to operate the walk-behind tractor, you need to check the level and add transmission oil to the gearbox. The nominal crankcase capacity is 1.5 liters.

The engine ignition system includes a magneto that provides a constant ignition timing. As wear occurs, the angle changes, which leads to unstable ignition operation. To adjust the ignition of the walk-behind tractor, it is necessary to control the moment when the breaker contacts begin to open and the maximum gap between them. The check is carried out with the flywheel removed by aligning the notch on the crankshaft with the notch on the base of the magneto armature.

The power system includes a K16N or ZiD-12 carburetor and a fuel tank holding 8 liters of gasoline. Adjusting the carburetor of the walk-behind tractor allows you to ensure uniform engine operation and the fuel consumption declared by the factory. The adjustment is performed with the engine warm by rotating the idle speed screw and the throttle limiter screw. This sets the minimum idle speed.

Ural with a Chinese engine

Many owners of Ural walk-behind tractors do not have enough power from the standard power unit. Instead, Chinese engines or other imported motors are often used. The Chinese engine is installed on a standard frame through additional cross members. The cross members are attached to the frame by welding or bolts. Imported power units have an increased crankshaft speed, so the use of homemade pulleys in the clutch is required.

The increased power of the power unit expands the possibilities for do-it-yourself modifications. The equipment is capable of working in winter with an installed rotary snow blower.

Advantages and disadvantages

Based on reviews of the Ural walk-behind tractor model range, a number of advantages can be identified:

• The weight of the product is 120 kg, so during operation there is no need to exert additional physical force on the control handles;
• possibility of alteration and modernization;
• the engine on the Ural walk-behind tractor with gearbox has a long service life;
• an effective air purifier that does not require replacement of filter elements;
• simplicity of design and the possibility of self-repair.

Owners note the following disadvantages:

• oil leaks at the joints of engine parts and gearbox;
• the need to check the oil level;
• increased fuel and engine oil consumption due to the design of the gas distribution mechanism;
• The walk-behind tractor is not suitable for long trips with a trailer due to the low speed.

The Ural walk-behind tractor is a time-tested unit. Beginning around the 90s, farmers realized how to make their jobs easier with this essential piece of equipment that was designed to last.

This technique still remains in demand and popular, despite the fact that it has many modern competitors. And all this thanks to a successful combination of power, endurance, quality and relevant technical characteristics.

Motoblock "Ural": history of creation

This walk-behind tractor model became one of the first in its class in the Russian Federation immediately after the collapse of the USSR. Production began back in the nineties. The first batch sold out in a huge circulation - more than 130,000 copies.

As of 2020, the Ural walk-behind tractor has a large number of different competitors. But it continues to remain relevant and in demand. The main reason for its popularity is the simultaneous combination of several important advantages:

• optimal ratio of power and fuel consumption;
• outstanding technical characteristics;
• simplicity of the device - accessibility of repair.

Assembly and subsequent release is carried out at the joint-stock company UMPO. It is a defense engine-building enterprise located in the capital of Bashkiria, the city of Ufa. All necessary spare parts are purchased there.

The manufacturer of walk-behind tractors Ural produces high-quality agricultural equipment. This unit differs from other foreign competitors in its power, endurance and durability. At the same time, a domestic motor cultivator will have an affordable price.

Disadvantages of the Ural UMZ 5V walk-behind tractor:

• it is low-functional - the capabilities of this equipment are limited only to plowing and soil cultivation;
• noise during operation;
• heavy weight;
• not intended for long distance travel.

Any equipment fails sooner or later. The reasons can be very different.

In the instructions for the Ural walk-behind tractor there is a section about breakdowns and possible ways to eliminate them. This information can be used to troubleshoot problems with the walk-behind tractor.

Often problems lie in the spark plugs and the possibility of a spark, the general condition of the carburetor and the quality of fuel entering the cylinder. If there is no spark, try disassembling the engine and replacing the spark plug.

The breakdown can also occur in engine starting and it is worth looking for its causes in the following problems:

• wire insulation is broken;
• contacts have oxidized;
• watering of fuel and oil occurred;
• The carburetor jets are clogged.

To solve the problem of why your walk-behind tractor won’t start, you should take the following steps:

1. Start the equipment.
2. Check the presence of fuel in the tank.
3. Make sure the carburetor choke is closed.
4. Check if fuel is entering the carburetor.

And if you feel that you cannot deal with the breakdown yourself, then it is better to contact a specialist in time.

To reduce the possibility of problems with the walk-behind tractor, we strongly recommend not to overload it and monitor the serviceability of the internal parts.

The popularity of Ural walk-behind tractors with a ZiD or UMZ-5V engine is difficult to overestimate. This is due to their power, durability and maintainability. But are these characteristics the only ones that attract farmers? Is there a way to make cultivators even better and what will installing Chinese engines on them give?

Motoblock Ural UMZ-5V: features of technical developments

At one time, the machine was excellent for working on heavy and clayey soil. She coped with her direct responsibilities even in the incredible heat. Moreover, repairing the model was very quick and easy, and spare parts were available in any quantity.

The Ural walk-behind tractor with the UMZ-5V engine was single-axle and was complemented by an oil tank with a capacity of 1.5 liters. The wide track was adjustable, so it could be easily adjusted according to the characteristics of the soil and the work process itself.

The unit did not differ in versatility and was used in most cases specifically for soil cultivation. It did not come with any attachments, so it was not suitable for cutting grass, removing snow or removing debris. At that time, it was recommended to use the UMZ-5V in the summer.

Negative aspects include the size and excessive weight of the structure, not much versatility and the impossibility of transportation over long distances. Also, during operation, the machine made a lot of noise, which provoked headaches and hearing impairment. Naturally, when wearing protective headphones, the negative impact was significantly reduced.

Attention! Models of the Ural walk-behind tractor are equipped with both domestically produced and foreign engines. The choice of one option or another depends entirely on the preferences and budget of the consumer.

In this video we will review the Ural walk-behind tractor:

Specifications

Due to their parameters, Ural motor cultivators have remained popular since their appearance on the market and their technical characteristics have largely become an example for other manufacturers to follow.

It is worth noting that the very first model Ural UMZ-5V is quite heavy. It weighs as much as 120 kilograms, despite the fact that it is intended for processing areas whose area does not reach a hectare. Working with the unit requires a lot of physical strength.

The flagship models of the Ural walk-behind tractor are powered by a domestic gasoline carburetor single-cylinder engine with four strokes and a power of five horsepower. Although the model of the domestic engine itself is quite old, it is still very reliable. In particular, it is very resistant to low temperatures. And air cooling allows the walk-behind tractor to operate in hot weather, since its motor does not overheat.

The brand of gasoline does not matter for this unit - it can work with almost any gasoline fuel. It is extremely economical in fuel consumption: having a tank with a volume of only six liters, it consumes no more than 2 liters per hour.

New model of Urals - Ural UMB-K Argos. It retains the best technical features of its predecessor, but thanks to some improvements it has become suitable for processing large areas. In particular, the engine power has increased, which in this device is 8 horsepower, instead of 5.

Technical characteristics of the Ural walk-behind tractor

The concept of the walk-behind tractor itself was developed relatively long ago. Despite this, it still remains relevant, the reason for this is its outstanding technical characteristics. Particularly important is the ability to carry out repairs “on the fly”, right on site.

Most of the breakdowns typical of a walk-behind tractor can be repaired using pliers and a screwdriver. More complex repairs will also not cause much difficulty for an ordinary summer resident.

Mass and dimensional characteristics

Dimensions and weight are one of the most important parameters for such equipment. Since work with its help is carried out seasonally. Accordingly, it requires periodic storage.

Dimensional characteristics:

• length - 1.56 m;
• width - 0.79 m;
• ground clearance - 0.28 m.

The weight of the walk-behind tractor is 120 kg. It is thanks to these parameters that the walk-behind tractor is very easy to transport and store. It will easily fit in the far corner of the garage or a small utility room in the country. It is possible to use attachments.

Engine of the Ural walk-behind tractor

The Ural walk-behind tractor is equipped with a UMZ-5V

. It was designed more than 25 years ago, but due to its performance characteristics it is still relevant. The carburetor engine is easy to repair and adjust independently. This engine is a four-stroke, single-cylinder. This is what determines the low fuel consumption of this engine.

Main performance characteristics of UMZ-5V:

• combustion chamber volume - 0.45 l;
• rated power - 5 hp;
• cylinder, diameter - 82 mm;
• shaft rotation speed - 2,350 min-1;
• The compression ratio during operation is 6.

Another important feature of this walk-behind tractor is its undemanding quality of gasoline, which makes a carburetor engine of this type compare favorably with its famous foreign analogues. Can operate on fuel with different octane ratings. AI-80 and AI-92 can be filled into the tank.

The ZID-4.5 engine was installed in separate batches of walk-behind tractors

. Its performance characteristics do not differ from the parameters of the UMZ-5V and its modifications.

Transmission

The transmission has only 3 speeds - one for forward movement, the second for reverse movement and neutral. This type of transmission is used with UMZ-5B and UMZ-5V engines. At the same time, the UMZ-5A type engine is equipped with only one speed.

The transmission of torque to the working part of the walk-behind tractor is carried out by a special V-belt transmission. At the same time, the latest UMZ-5V models can be equipped with four gears simultaneously.

The design is equipped with a special transmission, thanks to which the engine power is transmitted through a special differential. In some modifications of the walk-behind tractor, special types of transmission are installed, which ensure the operation of more powerful motors. Due to this, the efficiency of the equipment is significantly increased.

In fact, the walk-behind tractor belongs to the domestic automotive industry. Its transmission does not require regular maintenance - like many of its other components.

There are cases where no maintenance was carried out on a particular walk-behind tractor for more than 10 years. At the same time, the equipment continued to successfully perform all the tasks assigned to it.

Fuel consumption and carburetor

Motoblock engines of this type are equipped with a UMZ-5V

. It is not demanding on operating conditions. It can be used even in sub-zero temperatures. That is why the Ural walk-behind tractor is often used in winter - for transporting snow and solving other problems. At the same time, this carburetor, when properly configured, saves fuel. This is another reason for its popularity in our country.

If there is increased fuel consumption, it is necessary to adjust the engine speed using the carburetor.

This procedure is performed in the following order:

• the idle screw is screwed in completely, after which it should be turned out 2.5 turns;
• the throttle valve is closed all the way, after which it is set using a special screw to a position in which the engine runs stably;
• using the idle screw, the engine operating mode is selected in which its operation will be stable, but at the same time the damper will remain in one place;
• The screw that limits the opening of the throttle valve should be set to the lowest closing position - it is important that the engine operates sufficiently stable.

If, after performing all the above operations, the engine speed does not increase, this means that the carburetor is set to low speed. Due to this, it is possible to significantly reduce fuel consumption. The process is described in as much detail as possible in the manual that comes directly with the walk-behind tractor itself. Finding it on the Internet is not difficult.

Ural walk-behind tractor with UMZ 5V engine

A special feature of the Ural walk-behind tractor model with the UMZ 5V engine is its ability to process clay and other heavy soils without loss of operating efficiency. Combined with the ability to work in almost any climatic conditions and maintainability literally on the go, this has made the model one of the most popular among domestic gardeners.

The unit belongs to the uniaxial category. Its track is quite wide, but can be easily adjusted to suit operational needs. You can set the required value, both based on the characteristics of the soil and the work process. The package includes a one and a half liter oil tank.

The main purpose of such a motor cultivator is to cultivate a plot of land for the purpose of further planting selected crops on it. Work such as transportation of goods, haymaking, garbage and snow removal is possible only after installing attachments. At the same time, there is no shortage of models of the latter.

General technical characteristics of the Urals UMZ-5V:

1. weight - 120 kilograms;
2. air cooling of the motor;
3. 82mm cylinder;
4. gasoline engine with a power of 5 horsepower;
5. fuel tank with a volume of 6 liters.

The rather large dimensions and massiveness of the machine in the eyes of many are its main drawback. Because of this, it is quite difficult to transport it over long distances. Despite the fact that it is suitable only for processing medium areas. An important drawback is the noise level, which requires the use of protective headphones.

How to operate

The service manual for Ural walk-behind tractors of the UMP and UMB series is not much different from the operating instructions for any other similar unit, and in many ways it is even simpler than them. And first of all, the device is prepared for operation. To prepare, perform several extremely simple and universal actions:

• conduct a general inspection of the walk-behind tractor;
• check for fuel or oil leaks;
• set the gearbox to neutral position;
• measure what the fuel and oil levels are in the respective tanks;
• if necessary, add working fluids;
• check the operation of the engine by turning it on.

Ural walk-behind tractors have the greatest maneuverability compared to their competitors

If no problems were identified at the preparatory stage, work begins. For what:

1. switch the engine to low speed;
2. disengage the clutch mechanism;
3. turn on the required speed on the gearbox;
4. release the clutch release lever, which leads to an increase in speed and the start of movement.

But before starting constant operation of the unit, it is run-in. Thanks to this procedure, you can significantly extend the life of the Ural motor cultivator. This is carried out not only immediately after purchasing the device, but also after any prolonged downtime.

For proper break-in, you must:

• Start the engine at idle speed. Despite the fact that the gearbox must be in the neutral position.
• The unit operates in this mode for the first five hours, without load.
• After they are completed, the device is loaded at half power and it operates like this for the next 25 hours.
• Over the next 30 hours, the owner gradually increases the load on the machine until it reaches its maximum.

Important! Run-in is not carried out without first adjusting the belt tension.

Ural UMZ 5V

This unit, despite its excellent quality and good endurance, has one drawback - it is not entirely multifunctional. Therefore, it is difficult to call this model universal, since it can be used either for plowing an area or for transporting goods.

Specifications:

• engine power – 5 hp;
• operating speed: 1.9 km/h -15 km/h;
• vweight: 120 kg;
• number of gears: 4;
• cargo transportation weight up to 500 kg;
• ground clearance up to 28 cm;
• length: 1.5 m;
• width: 80 cm;
• height: 1 m

The engine of this device is gasoline, single-cylinder and air-cooled. A special feature of this engine is the ability to refuel it with absolutely any gasoline, as well as its durability and reliability. Gear-type walk-behind tractor gear unit with differential device. The unit is also equipped with a power take-off shaft and transmission.

With Chinese engine

A standard domestically produced motor is not suitable for all owners of Ural walk-behind tractors. In search of a solution to the power problem at an affordable price, they turn their attention to Chinese products. Chinese manufacturers offer products with a power of 10, 12 or more horsepower at a fairly low cost, accessible to almost every farmer.

Thanks to more powerful Chinese engines, the owner of a walk-behind tractor has increased opportunities to modify it to suit his needs. For example, they are used as quite powerful snow blowers.

Replacing the engine on a Ural walk-behind tractor with a Chinese one

Chinese engines are convenient for many owners of these units due to the ease of installation. To replace the standard domestic Ural engine with products from the Middle Kingdom, there is no need for any special modifications. It is enough to install additional crossbars.

Such crossbars, made of metal, are attached to the frame of the device using welding or bolts. The first method is considered more reliable. You will also need to install homemade pulleys in the clutch. The reason for this is the increased crankshaft speed of Chinese engines.

With ZiD engine

The UMZ-5V motor is not the only version of the domestic engine installed on motor cultivators produced by the Bashkir plant. An alternative was the ZiD-4.5. The reason that he could so easily replace another model is their great similarity to each other.

A special feature of the motor is the presence of a pulley and sprocket for driving the chain on the crankshaft. In this case, the transmission itself is located on the gearbox side, while the pulley is on the flywheel side. The lubrication method is splashing, for which oil is supplied from a one and a half liter pan by a plunger pump.

The engine is driven by a belt, and gears are changed using a handle. The transmission itself has two speeds, which are controlled in exactly the same way as on the UMZ-5V.

The UMZ-5B engine and its modification UMZ-5DU-B are a four-stroke, single-cylinder, air-cooled internal combustion gasoline engine and are intended for installation on self-propelled agricultural machines, and can also be used on stationary installations for the mechanization of various agricultural works.

The engine has a two-stage gearbox with gear ratios of 1:6 and 1:2.91, changing the speed of the output shaft. The UMZ-5DU-B engine has the same parameters as the UMZ-5B engine and differs in that it is equipped with a single-stage gearbox with a gear ratio of 1:6 and a gearbox shaft without a ratchet.

The engine was installed on Ural walk-behind tractors, which many still have and still serve today. It is difficult to find operating instructions, so we created this page for those who use Ural walk-behind tractors with UMZ-5A, B, UMZ-6A engines. You can download instructions

Technical characteristics of the UMZ-5A engine

You can find out more about the characteristics of the UMZ-5A engines in the instructions given above.

The most problems during operation are associated with setting up the carburetor, so here is an excerpt from the instructions:

Carburetor adjustment

Adjust the carburetor to low speeds on a warm engine in the following order:

1.Fully tighten the idle screw located on the side of the carburetor, and then unscrew it 2.5 turns

2. Close the carburetor throttle valve all the way and by rotating the screw that limits the closing of the throttle valve, set it to the smallest opening at which the engine is able to operate stably at idle speed.

3. By screwing in and then unscrewing the idle speed screw, find its position at which the engine speed will be the highest, while the throttle valve should remain motionless

4. Rotate the screw that limits the closing of the throttle valve, again set it to the minimum opening position, at which the engine runs stably

5. If after this, when rotating the idle screw, the engine speed does not increase, then the carburetor is adjusted to low speeds, but if the engine speed increases, the carburetor adjustment should be continued.

Installation of the control lever and speed controller.

Fig 3.

Each time the control lever is moved, the tension of the control cable must be adjusted again, otherwise the number of revolutions at which the speed control was set may change.

The correct tension of the cable is checked as follows: the control lever is placed in the uppermost position, corresponding to the maximum spring tension, and therefore, the maximum carburetor throttle opening and the maximum engine speed. In this case, the intermediate lever must be turned all the way and rest against the edge of the gearbox housing. If this is not the case, then it is necessary to change the tension of the cable by moving it in the connecting clamp and achieve the above position of the levers

The nut that clamps the spring washer on the control lever axis may become loose due to shock and the control lever will not be held in the desired position. It is necessary to tighten this nut so that the control lever moves only when pressing on it with your hand

The cable fastening in the connecting clamp and the connection of the cable with the intermediate lever may also become loose. The length of the cable will change and when the control lever is pressed to the uppermost position, the intermediate lever will not be adjacent to the gearbox housing, as a result of which the engine will not develop rated speed.

Ural UMZ 5V is a Russian-made walk-behind tractor, known on the market since the 1990s. This is one of the first such cars on the post-Soviet market. Today, the equipment is outdated, but is still in steady demand on the supported market. The main advantages of the model are its low cost and simplicity of design. The device is widely used in the CIS countries, and has established itself as a powerful and effective tool for gardening work. In the first years of production, the circulation of the Ural UMZ 5V was 130 thousand copies. The equipment has no analogues in its price category, so it remains relevant. The optimal combination of power, quality and technical characteristics are the striking advantages that have made the walk-behind tractor world famous.

Ural UMZ 5V is designed to perform various types of work in a record-breaking period of time. Due to its high performance, a walk-behind tractor equipped with a towbar is capable of transporting 500 kg of cargo and cultivating up to 2 hectares of land.

The machine has a wide track, which can be easily adjusted depending on the conditions in which the owner wants to operate it. Thanks to the correct settings, the walk-behind tractor can be adapted to certain conditions, and thereby ensure faster and easier work with it.

Please note that the design of the Ural UMZ 5V is in many ways inferior to the walk-behind tractors produced by the Minsk Tractor Plant. Therefore, the main activities of the machine are soil cultivation and cargo transportation. The walk-behind tractor cannot be equipped with attachments with which it could be used as a garbage and snow remover, grass mowing, etc. Thus, it makes sense to purchase such equipment for those who will use it in the summer to process crops.

In the last years of production, the walk-behind tractor was produced with a foreign power plant, which did not gain popularity. Car enthusiasts choose a domestic engine, for which they can find cheap spare parts. The engine is equipped with four gears.

The walk-behind tractor is quite reliable, and its simple design allows it to be serviced independently, in the garage. Moreover, many components and assemblies of the walk-behind tractor are so durable that owners do not change them for decades, and prefer to fill only with oil and gasoline. And yet, the manufacturer recommends timely maintenance, changing spare parts, etc.

How to independently adjust the ignition of a walk-behind tractor engine?

The engine starts with difficulty, does not gain power, and the noise from its operation has increased - one of the reasons may be early or late installation of the ignition.

Sequence of actions when working with the contact system:

1. Having opened the crankcase, set the maximum gap on the contact group by completely turning the engine crankshaft one revolution.
2. We set the piston to dead center. Its position is regulated by the engine instructions. There is a special mark.
3. We loosen the stator fastening elements and achieve closure of the contact group.
4. The adjustment after assembling the parts is completed.

In a non-contact system, when adjusting, the crankcase and ignition marks are combined, for this:

1. We open the crankcase.
2. At the piston dead center position, make a clearly visible mark on the rotor and crankcase.
3. When rotating the crankshaft, as soon as a spark appears, put a mark on the crankcase
4. The difference between the marks on the crankcase corresponds to the ignition timing.
5. We loosen the stator fasteners and set the angle in accordance with the instructions for the engine.
6. Ignition setup is complete.

The UMZ-5B engine and its modification UMZ-5DU-B are a four-stroke, single-cylinder, air-cooled internal combustion gasoline engine and are intended for installation on self-propelled agricultural machines, and can also be used on stationary installations for the mechanization of various agricultural works.

The engine has a two-stage gearbox with gear ratios of 1:6 and 1:2.91, changing the speed of the output shaft. The UMZ-5DU-B engine has the same parameters as the UMZ-5B engine and differs in that it is equipped with a single-stage gearbox with a gear ratio of 1:6 and a gearbox shaft without a ratchet.

The engine was installed on Ural walk-behind tractors, which many still have and still serve today. It is difficult to find operating instructions, so we created this page for those who use Ural walk-behind tractors with UMZ-5A, B, UMZ-6A engines. You can download instructions

The most problems during operation are associated with setting up the carburetor, so here is an excerpt from the instructions:

Carburetor adjustment

Adjust the carburetor to low speeds on a warm engine in the following order:

1.Fully tighten the idle screw located on the side of the carburetor, and then unscrew it 2.5 turns

2. Close the carburetor throttle valve all the way and by rotating the screw that limits the closing of the throttle valve, set it to the smallest opening at which the engine is able to operate stably at idle speed.

3. By screwing in and then unscrewing the idle speed screw, find its position at which the engine speed will be the highest, while the throttle valve should remain motionless

4. Rotate the screw that limits the closing of the throttle valve, again set it to the minimum opening position, at which the engine runs stably

5. If after this, when rotating the idle screw, the engine speed does not increase, then the carburetor is adjusted to low speeds, but if the engine speed increases, the carburetor adjustment should be continued.

Installation of the control lever and speed controller.

Fig 3.

Each time the control lever is moved, the tension of the control cable must be adjusted again, otherwise the number of revolutions at which the speed control was set may change.

The correct tension of the cable is checked as follows: the control lever is placed in the uppermost position, corresponding to the maximum spring tension, and therefore, the maximum carburetor throttle opening and the maximum engine speed. In this case, the intermediate lever must be turned all the way and rest against the edge of the gearbox housing. If this is not the case, then it is necessary to change the tension of the cable by moving it in the connecting clamp and achieve the above position of the levers

The nut that clamps the spring washer on the control lever axis may become loose due to shock and the control lever will not be held in the desired position. It is necessary to tighten this nut so that the control lever moves only when pressing on it with your hand

The cable fastening in the connecting clamp and the connection of the cable with the intermediate lever may also become loose. The length of the cable will change and when the control lever is pressed to the uppermost position, the intermediate lever will not be adjacent to the gearbox housing, as a result of which the engine will not develop rated speed. In this case, it is necessary to adjust the length of the cable as indicated above

The Ural walk-behind tractor appeared on the market in the Russian Federation back in the early nineties. During all this time it continued to be produced. It has proven itself well over decades of use in harsh conditions of cottages and gardens, and various climatic conditions. It is unpretentious, easy to repair, and has a number of other advantages over its analogues.

There are several modifications - the difference lies in the installed motors. Most buyers give preference to models equipped with domestic engines. The reason for this is the ease of purchasing parts for repairs; they are available in many stores and on the secondary market. There are certain features of operating the Ural walk-behind tractor. You will need to deal with them in advance, before purchasing. This will save the new owner from unpleasant surprises and possible difficulties.

Engine

Ural UMZ 5V is equipped with an air-cooled 4-stroke gasoline engine. The single-cylinder engine has a displacement of 0.5 liters and develops 5 horsepower. Its compression ratio is 6, and the cylinder diameter reaches 82 mm.

The power plant must be considered obsolete. But it has a very reliable design, proven over decades. Therefore, many owners prefer not to replace this unit with some Chinese engine. In addition, the domestic internal combustion engine is well adapted to any quality of fuel, and this should not be a problem.

Walk-behind tractor fuel consumption

The capacity of the walk-behind tractor's fuel tank is 6 liters. On average, the Ural UMZ 5V model consumes about 1.5-2 liters of fuel per hour of operation.

This model is equipped with a carburetor engine of the “UMZ 5V” model. The power plant, despite its obsolescence, is characterized by reliability and good technical parameters even for today. The 4-stroke, 1-cylinder petrol unit is air-cooled.

Characteristics of the UMZ 5V engine:

• working volume – 0.475 l;
• rated power – 5 hp;
• rotation speed – 2350 rpm;
• compression ratio – 6;
• cylinder diameter – 82 mm.

The UMZ 5V unit is not picky about the type of fuel and works perfectly on any type of gasoline.

The Ural UMZ 5V is not suitable for those who plan to cultivate their plot without much effort, since not everyone can pull a machine weighing 120 kg. Compared to the Neva or Oka walk-behind tractors, it is much more difficult to work with. That is why it is better to use it in small areas.

Production of the model began in Soviet times, which makes itself felt. Equipment owners complain about regular oil leaks. However, serious breakdowns with a walk-behind tractor are extremely rare. Usually you have to change small elements: gear plug, armored wire, spark plug, etc. Using its “native” power plant, the Ural UMZ 5V can operate for 20-30 years without failures.

The equipment is positioned as a vehicle, but it is not intended for long-distance transportation. On the road, the model can cause a lot of problems. The walk-behind tractor begins to consume a lot of gasoline and oil. At the same time, the Ural UMZ 5V engine becomes very noisy. When moving, you can hear the rattling of iron.

The power plant of the walk-behind tractor stands out for its power. The owners praise her, calling her a real “beast.” The engine can withstand almost any operating conditions, unlike foreign engines. Heat, long-term and heavy load are not scary for the UMZ 5V unit. Among the negative aspects, its noise should be highlighted.

The advantages of the walk-behind tractor include domestic assembly. Ural UMZ 5V breaks down very rarely. However, if this happens, the owner will be able to find spare parts for it as soon as possible. Their cost will be significantly less than that of foreign models.

Versatility is not a strong feature of this model. Only a few operations can be performed using technology. In this indicator, it is significantly inferior to modern walk-behind tractors, which stand out for their versatility.

The Ural UMZ 5V is quite a solid piece of equipment, but it is intended exclusively for plowing and cultivating the land, since even moving a load on it is not so easy.

Prices in Russia

Serial production of the Ural UMZ 5V walk-behind tractor is currently completed, but there is a lot of supply for sale on the secondary market. People willingly buy even those items that require restoration. After all, as mentioned above, the design of the model is simple and does not require professional skills.

Ural UMZ 5V on the supported market costs at least 10 thousand rubles, and the cost of cars in good condition can reach 30 thousand rubles. Moreover, the price depends not only on the condition, but also the model year. Before purchasing, it is recommended to inspect the equipment from all sides, and, if possible, conduct a detailed inspection of the bottom, since there may be corrosion there. The most valuable thing in the Ural UMZ 5V walk-behind tractor is the power plant. You need to pay close attention to it. The unit is already old, its overhaul will not be cheap.

The Ural UMZ 5V has practically no analogues, since this walk-behind tractor is, one might say, from a different era. Among more modern analogues that perform similar functions, we can highlight the walk-behind tractors “Cascade”, NMB-1, as well as “Oka” and MB1.

Purchase of new and used Ural walk-behind tractor

At the moment, serial production of this walk-behind tractor has been completed. But at the same time, you can still find this equipment for sale in new condition. The cost of "Ural" ranges from 10 to 30 thousand rubles. First of all, the price is determined by the condition, as well as the year of manufacture of a particular walk-behind tractor.

When purchasing, you should pay attention to the engine. Since repairing it in case of breakdown will cost the most. In turn, other faults will not be difficult to eliminate.

When choosing a used walk-behind tractor, it is also important to pay attention to the presence of drips. Since almost all walk-behind tractors, without exception, suffer from similar problems.

It is important that the walk-behind tractor does not overheat. It is quite simple to check this - with the engine running, you should significantly increase the speed. If the motor makes strange sounds or runs tight, you should refuse to purchase such a walk-behind tractor.

Owner reviews

• Alexey, Sakhalin region. A friend gave me a walk-behind tractor. I received the car in good condition, I've been using it for about a year. I use it for cultivating the soil, plowing and planting crops, and transporting goods. So far it works like clockwork, I service it myself in my garage.
• Pavel, Ryazan. I bought a walk-behind tractor on the secondary market for cheap. At this price, it still has no analogues, but its capabilities are colossal. It doesn’t even bother me that there is no support for attachments; it still justifies its price. A large fuel tank with a capacity of 6 liters, I would also note low consumption, and thanks to this the walk-behind tractor can boast a record power reserve compared to its competitors. The design is simple, I service it myself - it’s just one or two things wrong. It couldn't be simpler. In general, honor and praise to Soviet engineers, there was a time when they did it without any capricious electronics. I’ve been using it for three years now and I’m happy as an elephant.
• Igor, Kaliningrad. This is my first walk-behind tractor, very practical and reliable. Quite powerful and able to save fuel. The weight is substantial - about 120 kg according to the passport data. So he doesn’t need ground hooks. The equipment has a decent carrying capacity, soil depth parameters that are decent by modern standards, low fuel consumption and good maneuverability. Among the shortcomings, I note a noisy engine and vibrations, possible leaks from the gearbox and engine compartment, corrosion, and difficult gear shifting. Otherwise everything is fine. In any case, for its age, the Ural UMZ5V is holding up well. I'm not planning to sell yet.
• Nikolay, Irkutsk. Over ten years of use, the Ural UMZ 5V has served me faithfully. Now its body is practically covered with corrosion, especially in the lower part of the body and under the bottom. The wheels are rusty, the engine often shakes. Constant squeaks, vibrations, etc. In general, you can feel the age, but still works 100%. Perhaps I’ll finish it off, and then I’ll buy a new one.
• Semyon, Dnepropetrovsk. The technology deserves praise. They still knew how to do it in the Soviet years, not like now - they stuffed their pants full of electronics and happiness. This Ural has everything the old fashioned way, everything works reliably, since there is essentially nothing to break.
• Vasily, St. Petersburg. I liked the car, I've owned it for four years. I chose a copy in good condition, with an engine overhaul. I believe that the walk-behind tractor still has potential even by modern standards. The car consumes little fuel even under load. In addition, I would like to note good acceleration dynamics, simple design and cheap spare parts. For a Russian person, these are irreplaceable advantages, so I go and don’t complain. It’s a pity that you can’t install attachments, but it is possible to install a trailer. The weight of the transported cargo can reach an acceptable 500 kg, and even with a margin. The pendant is durable and will withstand any belongings. There is support for the ancient 92 gasoline. Decent smoothness, maneuverable steering wheel and precise gear shifting - you just need to lubricate it more often, and then everything will be fine.
