Ugra walk-behind tractor

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-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.

Types of mowers for walk-behind tractors Ugra

There are two main types of mowers suitable for the Ugra walk-behind tractor:

• rotary;
• segmental.

Although all three types of equipment are designed for a similar task, they differ in design and mode of operation. Let's look at them in more detail.

Zarya mowers will help get rid of weeds in your area

Rotary

The design of this type of mower is quite simple. At the base there is a frame on which several disks with moving knives for cutting grass are mounted. Most often, the mower is equipped with two or three such discs. In the side parts of the frame there are slides designed to support and adjust the mowing height.

Attention! The operating speed of a rotary mower is determined by the number of blades - the more blades there are, the higher it is. In this case, the performance of the mower must be commensurate with the power of the walk-behind tractor with which it is aggregated.

Many users prefer rotary mowers because of their two main advantages - ease of operation and safety. Thanks to this, anyone can use this equipment, including those who do not have any experience in operating small agricultural machinery.

In this video we will look at using the Zarya mower:

A notable feature of rotary mowers is the difference in methods of connection to the walk-behind tractor:

• front - trailed equipment for installation in front of the unit;
• rear - attachments for mounting behind the walk-behind tractor;
• semi-trailer - aggregated on the side of the device.

The Zarya and Zarya 1 devices are very popular.

Zarya successfully performs the following tasks:

• mowing grass in pastures;
• hay cutting;
• cutting thin bushes;
• mowing the lawn.

One of the valuable advantages of Zarya mowers is the ability to use them both on a flat surface and on slopes with a slope of up to 20 degrees upward and up to 8 degrees of side slope. The mower copes well with a variety of tasks - from mowing grass in parks and on roadsides to cutting thick thickets of grass and thin young bushes.

The device has the following characteristics:

• dimensions - 810x930x780;
• weight - 33 kg;
• operating speed - 2-4 km/h;
• strip capture - 80 cm;
• height of cut plants - up to 1 meter;
• stubble height - 7 cm;
• disk speed is 1800-2400 rpm.

Zarya 1 from Kadvi has the same functional features and advantages, but is a newer and improved version. This technique is quite universal in terms of its aggregation method - it is perfectly compatible with both Kadvi walk-behind tractors (Ugra, Oka) and heavy units of other brands. The cutting elements are designed in such a way that the mown grass lies in a continuous row, as after mowing with a scythe.

The device has the following characteristics:

• dimensions - 492x842x432 (up to 497);
• weight - 35 kg;
• strip capture - 80 cm;
• operating speed - about 3 km/h;
• height of cut plants - up to 1 meter;
• stubble height - 3-10 cm;
• disk speed is 2370-2635 rpm.

The productivity of both modifications of mowers reaches 0.2 hectares per hour. In other words, in just one full working day, a unit equipped with this device allows you to produce enough hay to make hay for one cow for the whole winter.

The distinctive advantages of the Zarya-1 modification should be noted:

• ease of installation and dismantling;
• thanks to adjustment to the stubble height, it can be used both as a lawn mower and as a hay mower;
• laying even rows of mown grass due to the new arrangement of cutting parts;
• convenience and ease of operation thanks to an increased turning radius and improved skids;
• The device is equipped with drums for pushing cut herbs, which allows you to cope even with dense thickets of plants and tall grasses up to 1 m.

The device is completely ready for use immediately after purchase and mounting on a walk-behind tractor and does not require any preparatory actions (debugging, lubrication, etc.).

Use rotary mowers for better processing of the area

Segmental

A segment mower for a walk-behind tractor functions somewhat differently than a rotary mower. Its basis is also the frame to which the wheels are mounted. They also house cutting devices moving along a reciprocating trajectory. Plants that fall between the edges of the knives are cut off. The cutting height of the grass is adjusted using a slide, as in the case of a rotary mower.

One of the popular models of segment mowers is the KN 1.1 model. Its productivity reaches 0.2 ha/h. The device has proven itself in operation in heavily overgrown, hard-to-reach and wet areas. Often these mowers are purchased by farmers for making hay. What also makes this model attractive is its ease of use and maintenance, as well as its affordable price. This mower is produced in Russia.

Specifications:

• width of the cut strip - 110 cm;
• number of knives - 4;
• cutting height 4 - 150 cm;
• rpm - 2500;
• speed - 2-4 km/h;
• weight - 45 kg.

Comparing these two types - rotary and segmented, we note that the uniformity of grass cutting is approximately the same. The main difference is productivity, which is significantly higher in the case of segmented equipment. Another distinctive feature of segment-type equipment is the placement of cut plants in continuous, even rows, which makes it very easy to clean up the mown grass. At the same time, when working with this type of device, the operator requires increased care to avoid the risk of hitting obstacles.

Review of Ugra walk-behind tractor models

For 2020, 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.

Review of the line of modifications of UGRA walk-behind tractors. Advantages and characteristics of walk-behind tractors

“UGRA” walk-behind tractors are the brainchild of the Kaluga plant (“KaDvi”) for the production of engines (gas turbines), power plants, spare parts for tractors, walk-behind tractors, as well as functional attached and trailed equipment for motorcycles.

Over the long period of its existence, Ugra walk-behind tractors have established themselves as reliable, time-tested, highly functional equipment, allowing their owners to cultivate medium and small acreage, including work in open ground and in greenhouses.

Thanks to the functional equipment, Ugra walk-behind tractors can be used all year round. In winter - as a snow removal unit or vehicle (if you use an attachment with a tracked drive); in the fall - for harvesting, preparing the soil for wintering, cleaning areas from leaves and debris; spring-summer - sowing work, hilling plants, mowing grass, etc.

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.

Line of models
