Do-it-yourself Agros walk-behind tractor repair

General information, purpose and design features

For starters, it’s about and “Agro” - absolutely identical walk-behind tractors. Agros is an earlier version, and the design of the model has remained almost unchanged over many years of production.

The car is produced at the Ufa Engine Plant, which was founded in 1925. In the 1920s and 1930s, the company was considered the largest manufacturer of aircraft engines in the USSR. In peacetime, the plant began to master the production of agricultural machinery. The company's workforce now consists of more than 200 people. As for the Agros walk-behind tractor itself, its production began in 1998. The project turned out to be so successful that over the past years, about 40 thousand walk-behind tractors of the same name, as well as various attachments for them, have been produced and sold.

The production of the walk-behind tractor of the same name was completed in 2008 due to a complete stop in the production of all such equipment at the Ufa plant. The fact is that the company began to receive more orders for the production of aviation equipment, which is more profitable. In this regard, the assembly of "Agros" was stopped. However, later the walk-behind tractor began to be produced at another plant, which belongs to the Chamber of Commerce and Industry of Ufa-Mechanika LLC.

The Argos model allows you to efficiently and effectively carry out work on cultivating the soil, planting and digging up root crops and other vegetable crops. The rich basic equipment allows you to perform the required amount of work for the first time. Thanks to the ability to connect various attachments, the walk-behind tractor can be turned into a full-fledged mini-tractor, capable of cultivating the soil to great depths, pumping water, transporting loads, etc.

Agros has a single-axle design with a power take-off shaft. The equipment is equipped with a manually locking differential. This device is responsible for distributing the load on both wheels, which is very important when driving in difficult terrain.

It can be noted without any doubt that the Agros walk-behind tractor, together with mounted options, has wider capabilities. That is why, when choosing this equipment, many people are looking at purchasing additional options that allow them to unlock 100% of the potential of the walk-behind tractor.

What if the gearbox chain fails?

Such a breakdown will be indicated by stopping the rotation of the power take-off shaft of the walk-behind tractor, and the gearbox itself will simply jam. It is possible that the chain itself has burst, then it just needs to be replaced and the PTO will resume its operation. Also, very often owners of walk-behind tractors have problems with adjusting attachments. For example, adjusting a plow on a walk-behind tractor involves the following actions:

• We secure the hitch with 1 kingpin, where the play in the horizontal position should correspond to 5° - 6°.
• We adjust the plowing depth. The norm would be somewhere deep into the ground by 5 - 7 cm.
• Adjusting the angle of attack. Place the walk-behind tractor with the plow on a flat surface. We unscrew the adjusting screw so that the plow touches the ground. And unscrew the screw back until the back of the canopy rises 2.5 cm from the ground.

These are the main points of plow adjustment that need to be made when installing it. Of course, this kind of breakdown of the Agro walk-behind tractor, such as turning on the power take-off shaft or adjusting the clutch, can be eliminated with your own hands without much difficulty. Also, if the Agro walk-behind tractor malfunctions, you should contact its instruction manual, where all problems with such equipment should be described in more detail. If you still understand, for example, that you need to disassemble the imported engine of your unit, that you are not sure that you will do it correctly, then it is still better to turn to specialists. Still, service centers can do detailed diagnostics and determine where the problem is with 100% accuracy. So, when in doubt, it is better to turn to professionals.

Auto mechanic, specializes in agricultural equipment

Agro walk-behind tractors are widely used among farmers and land owners. They help with plowing, harrowing, mowing unnecessary plants, and they can even be adapted for removing snow and transporting various loads.

These units have been produced in Ufa since 1999. The main feature is that engines for equipment are made in Russia, which significantly reduces the cost. In most cases, the Agro walk-behind tractor is equipped with a UMZ 341 engine, the repair of which is facilitated by the fact that the engine was designed right at the factory. Great reliability and good power are perfectly combined with the simplicity of the device control process. The significant weight and high pulling force provide excellent assistance in replacing manual labor with machinery.

“Agros” is a multi-purpose equipment, indispensable for work in personal plots, small farms, and is also in great demand in gardening, horticulture and the public sector.

The walk-behind tractor is very convenient for everyday use. Thus, elements of convenience include an adjustable steering rack, which can be adjusted horizontally and vertically. In extreme cases, the rail can be rotated 180 degrees. This feature allows you to better feel the walk-behind tractor when cultivating soil, clearing snow or driving on heavy off-road conditions. In addition, the correct setting allows you to adjust the machine to suit you so that you get less tired.

Unstable speed

The main complaint of owners about the operation of the device is the instability of engine speed, as a result of which it begins to sneeze.

The cause of the malfunction may be the establishment of a large gap in the gearbox cover, which should be adjusted to values ​​from 0.2 to 0.5 millimeters. In this case, power may decrease, which is a consequence of contamination of the carburetor, fuel pump hose or air exhaust filter, as well as crankcase failure and carbon deposits in the fuel combustion chamber. You just need to inspect and clean all the components.

Characteristics and dimensions

The Agros walk-behind tractor has the following characteristics: the track is 600 mm, the turning radius is at least 600 mm. The ground clearance of the walk-behind tractor is 250 mm. The equipment is designed to overcome fords up to 300 mm deep. Tire parameters – 6x12 inches. The maximum processing depth is 200 mm.

A 4-stroke single-cylinder carburetor running on gasoline fuel is responsible for performance. This is a domestic UMZ-341 engine with a power of 8 horsepower, which has a forced air cooling system. The design of the engine is completely identical to the Japanese Honda GX240 engine. A special feature of the engine is its low compression ratio, which allows it to work even with low-quality fuel. Thus, gasoline with both low and high octane numbers is allowed.

The cylinders in the engine are located at an inclined angle of 25 degrees. Let us pay attention to the improved lubrication system in the UMZ-341 engine. Thus, the operating principle of the new technology is not to spray oil, but to supply it under high pressure to the rubbing elements. The supply occurs under the influence of the oil pump after the oil has been filtered in a replaceable filter.

Among other characteristics of the UMZ-341 motor, we note:

• Dimensions: 490x440x375 mm
• Volume 0.3 liters
• Torque 17 N/m
• Compression ratio – 7.4
• The piston stroke is 68 mm, the cylinder diameter is 78 mm.

The engine, which weighs 35 kg, is started by a manual starter. Alas, there is no electronic starter even in the basic configuration. But there is support for cheap fuel starting from the A-76.

The engine works with a six-speed manual transmission, which has two speeds for forward movement. The built-in reverse allows you to move backwards and thereby improves maneuverability, which is very convenient, for example, when processing small areas with many obstacles that have to be avoided.

Prices in Russia

The average cost of a new Agros/Agro walk-behind tractor is in the range of 50-60 thousand rubles. This is what the basic equipment costs, while versions with attachments are much more expensive. Attachment options increase the price by an average of 10 thousand rubles.

Since the walk-behind tractor has been in production for decades, it can be found on the second-hand market in huge quantities. You should beware of specimens in poor condition, of which there are quite a lot. Experience shows that a walk-behind tractor in good condition will cost about 30-40 thousand rubles, including attachments.

The Agros walk-behind tractor successfully competes with the Belarus-09N and Burlak 10 DF models.

Areas of application and design of the Agro walk-behind tractor

The Agro walk-behind tractor belongs to the class of heavy agricultural equipment. The model is intended for active use in both small and large areas.

The tasks that the Agro walk-behind tractor successfully copes with include:

• effective cultivation of the site, regardless of the type of soil and the number of weeds;
• hilling beds planted with root crops and other agricultural crops;
• weeding between rows and beds;
• mowing vegetation of different heights and thicknesses;
• clearing the area of ​​snowdrifts;
• planting and harvesting potatoes;
• harrowing or plowing areas with virgin soils;
• transportation of luggage and gardening equipment with a total weight of up to 500 kg.

One of the main advantages of the Agro walk-behind tractor is its impressive weight. Thanks to the large mass, the equipment is pressed more tightly to the ground, which allows it not to slip and loosen the soil better, and also completely eliminates the unit’s sliding on the ice surface.

To manufacture the Agro walk-behind tractor, a standard single-axis design is used. The design of the model includes a power take-off shaft. In order to increase productivity, the manufacturer included a differential with manual locking in the walk-behind tractor configuration. This design feature allows the power of the unit to be evenly distributed on both wheels to improve maneuverability when moving up and driving in hard-to-reach places. A well-designed transmission of the walk-behind tractor allows it to move at any of four forward and one reverse speeds.

The engine of the Agro walk-behind tractor is equipped with a large fuel tank with a volume of approximately 5 liters. The large capacity of the tank in the design of the unit is due to its consumption of a significant amount of fuel - on average this figure is 2 l/h. work. All motor parts are made of durable metal alloys that are highly resistant to wear and corrosion.

The steering wheel of the Agro walk-behind tractor can be adjusted to the height of the operator. If necessary, it can be shifted relative to the original position in the vertical and horizontal plane by 30 ⁰. This feature significantly increases control accuracy when moving in hard-to-reach places.

How to adjust the carburetor on an agro walk-behind tractor

In order to configure the equipment, you need to understand what is being done in this case. For example, additional adjustments can be made without removing the device; for full adjustment, you will need to remove the technical element. Let's take a closer look at the process of installing options:

1. first of all, you will need to dismantle this device from the corresponding equipment location;
2. the next step will be a complete rinsing of the structural element in a gasoline solution;
3. Next, you need to completely clean the neck using a lint-free cloth, and also by moving the flap to the side;
4. the next step is to completely dry the device, after which the required gap is set using adjusting mechanisms. This is interesting: adjusting the carburetor of a walk-behind tractor.

At the final stage, the device is mounted in place, after which the cultivator is started. Here you will need to use the same adjusting elements to bring the damper position to the optimal level so that the mixture is supplied smoothly, while the engine has normal speed and smooth operation.

X45p

In this case, we are talking about a fairly high-quality analogue of the Japanese version of the fuel supply device for the engine. This device is configured in the same order, however, the need for periodic adjustment should be highlighted here, since failures may occur on such versions, which is due to the lower quality of the assembly and materials used. These indicators are partially affected, but at the same time the rather low cost stands out in comparison with the original Japanese spare part.

How to choose the right spare parts for an Agro walk-behind tractor

If the walk-behind tractor is constantly in active use, most of the likely defects still occur due to obvious wear of parts. According to statistics, similar equipment in most cases requires replacement of clutch devices or bearings. However, no matter what part needs to be changed, the choice of the newest one always depends on the brand of the walk-behind tractor manufacturer. There should be no problems with Agro units - this is one of the favorite Russian manufacturers, and the prices for spare parts for the Agro walk-behind tractor are even more affordable than for models imported from other countries.

It is important to consider the following aspects when choosing spare parts:

• Firm. The quality and additional service life of the devices depend on the manufacturer, its production policy and the materials used.
• Reputation of the spare parts supplier. It is recommended to purchase a product of this type only from proven companies that have already been able to justify their integrity. Only in this case, the owner is perhaps one hundred percent sure of the originality of the spare part for the “Agro” walk-behind tractor and the clear agreement with the brand of the unit.
• Service level. Not every owner of a walk-behind tractor has sufficient competence to independently purchase the parts he needs. You will need a specialized specialist who is able to select a better configuration of spare parts individually for your Agro walk-behind tractor.
• Price. This common rumor question is never left unattended - it must match the quality, but not be overpriced. On the other hand, you will like the low cost both in the image of an unreliable part and in a counterfeit of ordinary properties. Here, too, it is important to have a sufficient level of knowledge to distinguish a product that is not bad from a cheap imitation.

Simply put, having sufficient competence here to correctly select and install the necessary spare parts for our client, reviving the Agro walk-behind tractor will not be particularly difficult. As a representative of Russian agricultural machinery, which is still respected among other manufacturers in its industry, a well-repaired Agro will serve you for a long time without interruption.

The manufacturer does not produce a device for the Agro walk-behind tractor, but the universal hitch allows you to install adapters from other manufacturers. Some owners of motor vehicles make an adapter for a walk-behind tractor with their own hands.

Rotary mower

The KM-0.5 rotary mower is designed for the Agro machine. It consists of 2 self-sharpening knives located on the bottom surface. The height of the blades is 0.5-10 cm. The mower mows grass and small shrubs.

What homemade products to choose for the Agros walk-behind tractor

On today's market you can purchase hundreds of different attachments that will help make human work on earth easier. The cost of most of this equipment is not cheap, and not everyone can afford to purchase the necessary attachments. Therefore, many craftsmen make such homemade products for the agros walk-behind tractor.

The result is a high-quality and reliable model. Let's look at several types of mowers for walk-behind tractors that are assembled independently.

DIY rotary mower for walk-behind tractor

A rotary mower is used to cut grass for hay and to trim the lawn. Such a mower will mow tall grass, and chop fine grass.

To make a mower for a walk-behind tractor with your own hands, you need discs from a grain seeder and chains from a chainsaw gearbox. Each disk is equipped with 4 knives in specially prepared holes.

Install the knives so that they can rotate 360 ​​degrees. Two discs with knives are installed on a welded frame and tied. The rotation of the discs should be counter-rotating, which will allow the mown grass to be stacked in rows. It is also necessary to install a protective cover on the drive.

Mower-cart for walk-behind tractor

This mower is used in winter as a snow blower, and in summer as a mower. To do this, sprockets are installed on the winter version of the mower, and blades from the mower are installed on the summer version. This is a more complex version of the model. The mowed grass in summer can be hard, and the snow in winter can be covered with an icy crust. The design consists of two drums connected by a conveyor belt.

To make a cart, use a square pipe or corners, that is, whatever you find. Wheels and plywood are attached to the assembled frame. The stroller frame fits perfectly. The plywood must be thick. It can be replaced with a metal sheet. The proposed dimensions of the mower frame are 80x40 cm.

Cans with a large diameter are suitable for making drums. You can make 8 disks from a thin sheet of metal. The drums are attached to the frame by first inserting a bushing. The drums are connected by a transport belt, which can be made using a rubber strip.

Breakdowns and repairs

The Agro unit differs from other heavy-duty models in its long service life and reliable operation.

The operation of the walk-behind tractor is influenced by operating conditions, proper running-in after purchasing the factory unit, and timely maintenance and care.

If the unit is under warranty, then all repair work must be carried out by the module manufacturer. The owner has no right to open the seals and repair it. If the malfunctions of the walk-behind tractor are minor, then you can adjust its operation yourself.

Possible breakdowns and damage are presented in the repair instructions for the Agros walk-behind tractor and have a general appearance. Among them are the following:

• problems with starting and engine malfunctions;
• The chassis does not work;
• malfunctions in the gearbox (gearbox);
• clutch failures;
• the lubrication and cooling system is broken.

If the engine does not start, the reasons and solutions are as follows:

1. There is no fuel in the fuel tank. Fill the tank with fuel.
2. The hole in the gas tank cap is clogged. Open the tank cap, clean the hole and reinstall.
3. Fuel is leaking from the carburetor. It is necessary to adjust the carburetor of the walk-behind tractor.
4. Fuel system clogged. Drain the fuel from the fuel tank, rinse with gasoline and blow out the carburetor jets, inspect the spark plug.
5. Filter clogged. Replace or clean the filter.

If the engine operates with noise, knocking or jerking, it is necessary to adjust the valves on the Agro walk-behind tractor using special probes.

If the idle speed is unstable, the gap in the gearbox cover may be too large, so it is necessary to adjust the gap to 0.2-0.5 mm.

A decrease in the power of the walk-behind tractor is possible in the following cases:

• clogging of the carburetor, gas hose, air filter;
• crankcase cuff failure;
• carbon deposits in the combustion chamber.

Elimination methods include inspection, cleaning all parts, and blowing off the hose.

If the starter of the Agro walk-behind tractor fails or the fuse blows, the best solution is to replace unsuitable parts.

Malfunctions of the gearbox chain appear as a result of its jamming. The clutch can be damaged if the chain breaks, so it needs to be replaced.

The following failures and breakdowns are possible in the gearbox:

• the kinematics inside the gearbox are disrupted;
• spontaneous gear changes or their complete absence;
• oil leak on the shift shaft.

It is better to repair the box in special workshops. A gearbox is a complex unit, and you can’t do it without knowledge of mechanics.

Ignition system

In the “why there is no spark” problem, the reasons for the breakdown lie in the details, such as:

If there is no spark or sparks weakly, it is necessary to adjust the intermediate gap and check the condition of the electrodes. The gap norm is 0.8 mm.

When there are changes in the gap between the intake and exhaust valves on the engine, they are tightened or relaxed to the permissible value.

A low compression ratio has been detected in the cylinder. All worn parts are removed and replaced.

Cleaning the muffler will also help get rid of the spark problem.

Engine replacement

If the engine for an Agro walk-behind tractor breaks down and needs to be replaced, use an adapter kit. Instead of a native motor, imported ones with a cylindrical shaft with a diameter of 25 mm are suitable:

• Weima - with a power of 13 hp. With.;
• Subaru EX 27 - 9 l. With.;
• Honda 9 - 13 l. With.;
• Lifan 9 - 13 l. With.

Replacing the engine is as follows:

• remove the motor from the cultivator and dismantle the clutch mechanism;
• remove the drive cup under the conical shaft and replace it with one machined under the cylindrical one;
• A walk-behind tractor clutch is installed on the imported engine and connected to the transmission.

With constant use of the machine, spare parts may wear out. Most often, parts of the clutch mechanism and bearings need to be replaced. There are no problems with choosing parts for Agro. They can be purchased both from official dealers of the company and in the open market.

Owner reviews of the Agros walk-behind tractor

On agricultural forums you can find many kind words addressed to the Agros walk-behind tractor from its owners. The nature of these reviews is approximately as follows: “I have been using Agros for 10 (or more) years, and have never regretted this purchase.” It is noted that this walk-behind tractor can withstand heavy loads and all the most difficult operating conditions very well.

Agros has a very robust, efficient and durable engine, which, provided that the oil is changed regularly, does not cause any problems. The walk-behind tractor transmission is also very reliable and unpretentious in operation and maintenance. In addition to cultivating the soil, the Agros walk-behind tractor also performs excellently in mowing: it mows efficiently, is not afraid of hitting bumps and other “surprises” of the terrain that are not noticeable in the tall grass.

According to many owners, the cutter of the Akros walk-behind tractor is not designed to work on heavy soils or to great depths: “You can’t work with it like a regular walk-behind tractor - with cutters instead of wheels. Too high speed. Can only be used for shallow processing, and it is better to immediately reduce the speed.” "Agros" loosens the soil quite finely - approximately 8 centimeters deep; if you want deeper processing, you have to go through the same area twice.

There are some instances of walk-behind tractors with other carburetors designed for operation in power plants. In conjunction with such a carburetor, the engine may stall in the event of sudden increases in load. The problem is solved by replacing the fuel nozzle.

In other words, the complaint about the operation of this carburetor is that the walk-behind tractor engine is capable of operating in a variety of modes, but the carburetor is unable to support this: at idle and medium speeds there are no problems, but when heavy loads occur, up to full load , the speed starts to fluctuate, or the engine stalls.

Some owners are outraged that the fuel tank has a flat bottom. It’s good that it’s compact, but it doesn’t provide fuel to the engine when the tank is not full and under different operating modes of the walk-behind tractor! It would be better to make the tank cylindrical, or with a “cone-shaped” bottom, indicate the owners of Akros.

Some people find it not very convenient to work with a cutter: “the PTO lever is made low, there would be something like a bull bar in front.” There is also quite significant noise and vibration during the operation of the walk-behind tractor, which quickly tires both hands and ears.

But in general, it should be noted that the Akros walk-behind tractor has not earned any truly serious complaints over all these years, and is a very reliable professional-level equipment.
