The history of the creation of the Ugra walk-behind tractor

The walk-behind tractor itself was developed in . This enterprise has the organizational form of OJSC and has been successfully operating since 1966. Previously, this enterprise was several separate ones. It is built on the basis of:

• Kaluga Turbine Plant;
• Kaluga branch of the Research Automobile and Motor Vehicle Institute.

Production at this plant is carried out on a high-precision, fully automated conveyor. It is a line formed from unique foreign-made equipment. That is why Ugra walk-behind tractors are among the most reliable and functional in their price segment. The production of this equipment has been carried out for more than 10 years. During all this time, the walk-behind tractor has proven itself only on the positive side.

Cargo transportation and transportation

4.1. Cargo trailer. Trailers for walk-behind tractors can have a load capacity from 300 to 500 kg. The body is usually tiltable, and the cart itself may be equipped with brakes, lights and an operator's seat. The trailer is convenient, as it facilitates work when harvesting crops and transporting various cargoes.

4.2. Wheels with lugs. These metal wheels help increase traction. They are heavier than pneumatic ones and do not become clogged with soil. Thanks to this, the lugs do not slip under load.

4.3. Weights. They are hung on the body or on wheels in order to increase the weight of a light walk-behind tractor and so that a heavier attachment can be installed on it.

4.4. Riding module. This is an adapter trailer that helps turn a walk-behind tractor into a mini-tractor. It consists of a rear axle with a seat and a hitch for trailed equipment.

Technical characteristics of the Ugra walk-behind tractor

Another reason for the popularity of this technology is its outstanding technical characteristics. Moreover, based on them, it is worth making a choice in favor of the Ugra walk-behind tractor. Since it is used to solve strictly defined problems.

Engine of the Ugra walk-behind tractor

One of the most important features is the ability to purchase this walk-behind tractor with different engines. All of them can be divided into two groups - foreign production and domestic. They differ in design, but their performance characteristics are practically the same. All of them are united by the use of fuel of a similar type - AI-92 gasoline.

Today it is possible to purchase a Ugra walk-behind tractor equipped with the following engines:

• Kadvi DM-1M3 - 8 hp;
• Honda GX-200 - 6.5 hp;
• B&S Vangard - 6.5 hp;
• B&S Intek - 6 hp;
• Lifan 168-F2 - 6.5 hp;

• Subaru EX-21 - 7 hp;
• Kadvi 168-F2 - 6.5 hp;
• Mitsubishi - 6 hp;
• Lifan 177-F - 9 hp.

The choice in favor of a certain type must be made based on the nature of the soil. If it is clayey, there are a large number of rocky inclusions, then it is best to purchase a walk-behind tractor with a high-power engine. If you need to cultivate soft black soil, you can use a low-power engine. The processing speed directly depends on the power of a particular engine.

Gearbox of the Ugra walk-behind tractor

The gearbox of the Ugra walk-behind tractor deserves special attention. This equipment includes a gear drive made of cermet disks. Due to this, their strength and service life are significantly increased. The main advantage is the maintainability of this unit. It will not be difficult to order all of its individual parts at the factory.

Other important advantages of the standard gearbox of the Ugra walk-behind tractor include:

• lack of drive V-belts;
• the presence of as many as 3 speeds for moving forward and 1 speed for moving backward.

Another important advantage resulting from the use of V-type belts is the absence of operational difficulties such as jumping, slipping, or breaking. Due to all this, work with various types of towed devices and various attachments is greatly simplified.

The figure above shows a cross-section of an example of a walk-behind tractor gearbox of this type. It includes the following main components:

Transmission of the Ugra walk-behind tractor

The transmission of this walk-behind tractor, regardless of the model, necessarily includes the following main components:

• gearbox;
• differential;
• clutch;
• Transmission.

This type of walk-behind tractor uses a typical gear transmission. It includes bevel as well as spur gears. During assembly, the engine must be rigidly attached directly to the gearbox itself. It is attached to the angular gearbox - this is how the process of transmitting rotation occurs.

It is important to remember that for proper operation of the entire transmission mechanism, you should not try to disassemble it. Since compliance with the basic rules of operation requires compliance with certain regulations. This process has its own characteristics; it is not only difficult, but impossible to carry out at home.

An important advantage of this type of walk-behind tractor is the presence of a power take-off shaft. Due to this, it is possible to use various types of attachments.

Technical characteristics of components

Such a large number of different types of work becomes possible with the use of original attachments, which are best purchased from the manufacturer. The gearbox, equipped with two power take-off shafts, additionally allows the use of a feed cutter, earth drill, and pump. High reliability of operation, backed by a two-year manufacturer's warranty, is ensured by a metal-ceramic clutch and a gear drive. The optimal operating speed—from 3 to 8 km/h—is set by a four-speed transmission. The engine has one cylinder. The weight of this unit reaches 95 kg. A low center of gravity and a clearance of 0.17 m provide high stability during operation. Optimal fuel consumption varies between 2-2.5 liters of fuel per hour, achieved by using a convenient removable cleaning filter. Manufacturers took serious care of operator safety and equipped the unit with a universal, intuitive, two-handle control system. It is designed specifically to avoid traumatic situations.

— (this is the design of the block in CSS)

The difference between the 1N1 model, equipped with a domestic Kadvi engine, and the 1N15, equipped with a Chinese 9 hp unit, is about 10 thousand rubles. Moreover, this price is set at the manufacturer. Accordingly, equipment purchased in resale stores will cost even more.

For the most part, models equipped with a foreign-made engine are more reliable. But at the same time, they are much more difficult to repair. At the same time, the Cadmi motor cannot boast of its reliability. But, at the same time, the process of repairing it takes less time. Spare parts are more accessible and purchasing them will not be difficult.

Most popular models

That is why the optimal solution is to purchase and subsequently use original attachments.

Model 1N7

A common model among farmers is a walk-behind tractor with a lifan engine. This unit is very reliable, and its power is enough even to cope with heavy clay soil, which is not always possible for semi-professional equipment. The manufacturer chose a Chinese engine for this model, as it showed its best performance in our harsh climate.

The unit in question has high technical qualities. The Ugra walk-behind tractor is equipped with a professional gearbox with an increased safety margin and a gear transmission. Its other characteristics include:

• • gasoline four-stroke engine;
• • fuel tank with a volume of 3l100ml;
• • AM-92 gasoline;
• • air cooling;
• • 3 forward speeds;
• • 1 reverse speed;
• • metal-ceramic clutch discs;
• • manual starter;
• • speed when transporting goods 9 km/h;
• • maximum trailer weight 350 kg;
• • tillage width from 40 to 70cm;
• • soil cutting depth 30cm;
• • weight 90kg;
• • 18 month factory warranty.

The Ugra walk-behind tractor has a power of 6.5 hp, which is enough to use all kinds of attachments. It is used with trailers and adapters with a seat, potato planters and diggers, water pumps, snow blowers and lawn mowers, harrows, plows, hillers and weeders. Thus, the Ugra 1N7 walk-behind tractor turns out to be the most universal unit, making the farmer’s life easier in many ways. The reliable engine of the Ugra walk-behind tractor allows it to be used all year round, even in the harsh Russian winter.

Owner reviews of the walk-behind tractor

You can find both positive and negative reviews about the walk-behind tractor. At the same time, it is worth highlighting a number of different points that all users of this technology, without exception, pay attention to. These include:

• maintainability;
• use of hex pins;
• presence of reverse gear;
• relatively recently the reverse gear handle was removed from the design.

One of the most important positive aspects is the maintainability of this equipment. Especially if you purchased a walk-behind tractor with a domestically produced engine. Official dealers always have spare parts for this equipment in stock.

Moreover, their cost is relatively low. If necessary, it is possible to return the walk-behind tractor for warranty service - the manufacturer provides it for a period of 24 months.

Walk-behind tractors produced before 2013 were equipped with hexagonal pins. But the manufacturer took this design flaw into account and from the time indicated above began to produce equipment equipped with completely round pins.

Again, walk-behind tractors produced before 2013 were equipped with a special reverse handle. The main problem was the possible underpressure of this switch. If you engage reverse gear when such a situation occurs, there is a high probability of transmission failure. The manufacturer took this important drawback into account, after which this handle was removed. This made it possible to reduce the likelihood of accidental breakdown of the gearbox and other important components of the walk-behind tractor.

If you purchase from a dealer rather than a factory, it is important to remember that equipment of this type must be equipped with an appropriate extension cord. Thanks to the installation of this extension, the track of the walk-behind tractor becomes significantly larger, thereby increasing the plowing area. Often, unscrupulous sellers offer to pay extra for this extension cord and do not notify their buyer that it is included in the standard, basic package. It is important to carefully check the availability of everything that is included in the standard kit.

Some users indicate the difficulty of climbing at an angle of 200 or more. It is important to remember that the main purpose of this equipment is to perform various types of work with the soil. All other functions implemented using this walk-behind tractor are secondary. Therefore, if you need to transport goods, clean up the area, or perform other tasks on a large scale, you should simply purchase highly specialized technical equipment.

The solution to transportation difficulties is to install a special trailer with a power take-off shaft. Using this type of attachment it will be possible to significantly increase the “transporting capabilities” of the Ugra walk-behind tractor. But it is important to remember that the cost of such equipment is about 15 thousand rubles. Which is equal to almost 50% of the cost of the walk-behind tractor itself.
