Motoblock "Ugra": technical characteristics

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.

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-17 - 6 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.

Review of Ugra walk-behind tractor models

For 2016, a distinctive feature is the presence of an extensive range of Ugra walk-behind tractors. The catalog on the official website of the manufacturer presents the following:

NMB-1N1 - Kadvi DM-1M3 engine 8 hp;
NMB-1N2 - Honda GX-200 6.5 hp engine;
NMB-1N3 - Intek engine 6 hp;
NMB-1N7 - Lifan 168-F2 - 6.5 hp;
NMB-1N9 - Lifan EX-17 - 6 hp;
NMB-1N10 - Lifan EX-17 - 7 hp;
NMB-1N11 - Kadvi 168-F2 - 6.5 hp;
NMB-1N13 - Mitsubishi - 6 hp;
NMB-1N14 - Lifan 177-F - 9 hp;
NMB-1N15 - Lifan 177-F - 9 hp.

The most important difference between all the above models is the engine, as well as its power. The installation of a foreign unit has a significant impact on the cost of a particular walk-behind tractor.

— (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.

Attachments for the Ugra walk-behind tractor

Another important advantage of the Ugra walk-behind tractor is a large number of various attachments. Today the original attachments are available for sale:

potato planter;
plow;
weights;
coupling devices;
walk-behind brush;
cutter-cultivator;
tiller-cultivator;
hiller;
harrow;
heavy single-axle cargo trolley;
walk-behind shovel;
lugs;
differential;
digger;
rotary snow blower;
cutter-cultivator.

All of the above equipment can be installed on a walk-behind tractor with minimal time. Since there is no need to make any structural changes to the structure of the walk-behind tractor itself. Initially, the attachment is equipped with everything necessary for installation on the Ugra walk-behind tractor. That is why the optimal solution is to purchase and subsequently use original attachments.

Attachments

To install additional equipment, multifunctional seats are provided on the walk-behind tractor body. again there are two heavy-duty power take-off shafts with a diameter of 25 mm, which allows the installation of large diameter cutters and additional weights. This is useful when processing rocky soil and working at maximum depth.

Below is a list of the main additional devices:

Plow
Lugs
Potato pickers
Hitch
Hiller
Milling cutters
Weights

The Ugra walk-behind tractor has good stability and controllability. Its curb weight is 90 kg, which allows it to work on heavy soils without effort on the part of the driver. But this weight also has its own peculiarity - it will be difficult for a teenager or a woman to operate the unit on loose or wet ground.

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.

Model features

The reliability of the Ugra walk-behind tractor is ensured by its simplicity - it contains complex parts and mechanisms that are sensitive to loads. The engine is started mechanically using an ignition cable, which does not require much force. A simple but effective air cooling system prevents the engine from overheating even at maximum load.

The high power of the walk-behind tractor is convenient when working with a trailer; it increases the cross-country ability and the weight of the cargo that can be transported. Ease of control is provided by a handle that can be adjusted in height. again, the handle rotates along a vertical axis, which is convenient to avoid trampling. For safety reasons, the Ugra walk-behind tractor is equipped with an ignition interlock system.

The track width of the walk-behind tractor can be varied within 40-70 cm, which is convenient for processing the sown area. The wheel diameter is 20 inches, the tires are equipped with significant tread, providing high flotation, which is convenient when cultivating loose or wet soil. If necessary, the track width can be increased using specialized extensions. again, it is possible to install extensions on the power take-off shafts.

With such characteristics, the Ugra 9.0 liter walk-behind tractor. With. allows you to process a strip of soil up to one meter wide to a depth of up to 32 cm. A fuel tank with a capacity of 6.5 liters is enough for two hours of operation at maximum power and 3-4 hours of operation in normal mode. During driving, its resource is much longer and depends on the weight of the trailer and cargo.
