Motoblocks "Ugra": features and operating instructions

You can talk about the benefits and value of motoblocks in your personal household for a long time. Another thing is much more important: each brand, even each line of this technique has many interesting and relevant features. It is useful to understand what are the characteristics of the Ugra series motor-cultivators, how they can and should be used when processing summer cottages.

The products of the KADVI enterprise, despite the harsh, even fierce competition, are successfully sold on the Russian market. European and Chinese concerns cannot supplant the products of this brand. The joint-stock company Kaluga Engine is engaged in the production of motoblocks. At the company's facilities, equipment for small-scale mechanization was produced 30 years ago. Of course, since then, production has significantly improved and modernized more than once.

According to experts, Kaluga motoblocks have already come close to the European level. A striking example of such achievements is the Ugra line. Its power starts from 6.5 liters. with. Thanks to the use of high quality parts, including impeccable motors, the equipment successfully withstands significant loads. Power plants from leading foreign manufacturers, which have proven themselves well, are often used for completing.

The power is quite enough for the use of attachments of various types, including:

• water pumping pumps;
• trailed carts;
• adapters;
• potato planters;
• lawn mowers;
• hillers;
• weeding workers;
• plows;
• harrows and some other additions.

When choosing between different models, you should pay attention to the main characteristics that the manufacturer indicates:

• labor productivity;
• resistance to harsh climatic conditions;
• compliance with EU safety standards;
• the ability to do hard work on tight deadlines.

It is useful to start parsing models of walk-behind tractors with the version "Ugra NMB-1N7"... It can be supplemented with mounted and trailed tools from a variety of companies. The weight of the structure reaches 90 kg. The rigid frame supports the Lifan four-stroke petrol engine. The engine has only one cylinder, which does not prevent it from developing an effort of 6.5 liters. with.

The designers have provided for compulsory protection against overheating by blowing air. Starting is done with a manual starter. Model "NMB-1N7" Equipped with two power take-off shafts. The clutch is made of a variety of ceramic discs. Reverse is provided, which can be very useful. Each stick is vibration-resistant. If necessary, the motor can be easily stopped with one button. The steering column can be adjusted vertically and horizontally. The walk-behind tractor is capable of pulling a trailer (with a total hitch weight of 350 kg).

"Ugra NMB-1N17" - a heavy motor-cultivator, the mass of which reaches 98 kg.

The delivery set includes:

• axle extensions;
• 4 cutters;
• transport wheels;
• head gasket;
• company instruction.

The installed motor power reaches 7 liters. with. Lifan has a stable performance and makes only a little noise.The heavy block is an advantage when working on virgin soil. Together with the reverse gear, the device has 4 speeds. It is equipped with a gear reducer, the body of which is made of steel. Since there are no belts in the design, they do not have to be replaced.

The delivery set includes:

• wheels of pneumatic type;
• two soil mills;
• coupling devices;
• opener and bracket for its mounting.

To work with these components, you need to use gasoline no worse than AI-92. The tiller can plow the ground to a depth of 30 cm with a plowing strip width of 102 or 73 cm. The fuel tank contains 3.6 liters of fuel. The undercarriage of the unit is made according to a uniaxial scheme. In order for the device to turn, it needs a radius of at least 150 cm. Usually the track is 40.5 cm, but due to the extension cords it can be increased to 69.5 cm.

A good alternative to this version is "Ugra NMB-1N2"... The power of the walk-behind tractor is the same - 6.5 liters. with., and it also has 3 forward and 1 reverse speed.

Package Included:

• 4 loosening cutters;
• pneumatic wheels;
• branded opener.

The motoblock is equipped with a Japanese carburetor-type four-stroke engine (cylinder capacity - 196 cm3). The device can climb the slope (up to 20 degrees). The wheel arrangement of the device is 2x2 with a turning radius of 150 cm. The unit is normally equipped with four cutters, but at the request of the owner, you can put two more. According to the scheme, the walk-behind tractor belongs to the classic type, equipped with power take-off shafts.

The manufacturer declares that this device is fully compliant with EU safety regulations. It is very easy to bring it into the transport position. After such a transformation, the walk-behind tractor can be put in the trunk of a passenger car. Only the use of wheels with pneumatic tires is permitted. The capacity of the fuel tank is 3.1 liters, the hourly fuel consumption is 0.23 liters per hour at rated power.

Motoblock "Ugra NMB-1N9" is considered a good helper in gardening - he will cope with the cultivation of both virgin and already cultivated lands. The total area of ​​the cultivated area reaches 50 acres. The unit is equipped with a Subaru gasoline engine. It differs, like other Japanese products, in unpretentiousness and increased reliability. Longitudinal crankshaft placement minimizes vibration and increases uptime.

The manufacturer claims that during the production of the walk-behind tractor, they are equipped with a professional-class gearbox. For the manufacture of the main components of the gearbox, cermets are used. As a result, the reliability of the system is increased, the use of belt drives, which traditionally create many problems, is eliminated. One of the four gears works in reverse, it shows itself perfectly when interacting with various trailers and attachments. This walk-behind tractor is considered the safest among other models produced in the Russian Federation.

If necessary, you can very quickly stop the power plant or unlock the rear clutch, so stopping in the event of an abnormal situation is not a problem. There are various ways to adjust the steering column. Thanks to the two power take off shafts, it is possible to transfer power from the engine even to the drilling system or to the circular saw. The walk-behind tractor works great when equipped with weights, which is very useful when the grip is worse than normal.

Block "Ugra NMB-1N10" no worse than diesel units supplied by other manufacturers. The premium variation of this model comes with a Japanese motor.Despite this, it turns out to be cheaper than other devices.

The car is considered a good solution for the following jobs:

• cultivation;
• cleaning garden plots from snow and fallen leaves;
• plowing the land;
• garbage disposal;
• transportation of small loads over short distances.

The appearance of the model does not differ from other options, however, a significant difference is observed in the fuel supply system. The gear reducer helps to make the walk-behind tractor more reliable. With the help of special fenders exposed above the wheels, the designers protected the operators of the equipment from the ingress of dirt. A carefully thought-out folding frame to the limit simplifies the parking of the walk-behind tractor.

The device has proven itself well in the production of heavy, demanding work in the garden, in the communal sphere. It is an irrational decision to use it in relatively small areas, where the plowing area is small, and large loads are rarely transported. However, with an active load, this technique can be used all year round, regardless of the air temperature. Due to its small size, it is easy to transport it to the dacha or back in the car. The layout is traditional for heavy motoblocks, however, because of it, difficulties may arise with the connection of "extraneous" attachments.

Since the designers minimized the proportion of plastic elements, the mechanism turned out to be rather heavy, but at the same time its reliability increased. High-quality metal allows you to calmly work the soil without fear of damage to certain parts. The width of the cultivated strip of land can be 90 cm at a depth of 32 cm. Of the 4 speeds, 1 is intended for reverse. The fastest driving pace is 8.5 km / h.

High performance along with relative lightness is largely achieved due to the Japanese single-cylinder engine. The four-stroke engine was originally designed in such a way that many manipulations are carried out as efficiently as possible. Even the best analogs supplied from China and European countries cannot yet boast of such reliability. The developers deliberately abandoned the usual configuration of the combustion chamber. They changed it to improve startup speed and make it less harsh while reducing operating noise. The device works well at low air temperatures and almost does not overheat in the heat.

A walk-behind tractor often becomes an equally attractive choice. "Ugra NMB-1N14"... This version is suitable for large estates and small agricultural enterprises. The motor of such a device is simple and reliable.

With the help of a walk-behind tractor, you can:

• plant potatoes;
• move relatively heavy loads;
• remove snow;
• to plow the virgin soil.

The power of the unit is 9 liters. with. The generated energy can be transmitted to the power take-off shafts. The plowed strip is 60 cm and can be worked 35 cm deep. An electric starter is not provided. The mass of the walk-behind tractor is 85 kg, it moves with three speeds forward and with one backward.

Package Included:

• replaceable parts;
• cutters;
• wheels of pneumatic type;
• accessories.

The steering wheel can be adjusted to suit the individual needs of the operator. Thanks to a well-thought-out steel casing, contamination of the working parts of the walk-behind tractor can be avoided. The tank holds noticeably more fuel than other versions. The large wheels are covered with an aggressive looking tread that allows them to move on all types of soil. The device is equipped with a chain gear, the transmission of force occurs through a V-belt transmission. The ground clearance of this model is 17 cm.The size of the working track reaches 71.5 cm.The walk-behind tractor can only work on the AI-92.

The developers were able to ensure minimal disturbance of plants in adjacent rows (when the walk-behind tractor is on a specific row). If you use a trailer, you can move up to 500 kg of cargo. For adhesion, special sintered discs have been selected. The handle is easy to adjust to the height of the operator.

With additional equipment you can:

• remove snow;
• mow lawns and lawns;
• crush pet food.

It is appropriate to end the review of the model range on the description of the modification "Ugra NMB-1N15". The device is equipped with a Chinese motor with a capacity of 9 liters. with. The plowing depth is 30 cm and can be used with 4 or 6 cutters. The transfer of energy to the disc clutch allows you to work on land swaths up to 102.5 cm. This energy is generated by a four-stroke gasoline engine, fuel is supplied to it from a tank with a capacity of 6 liters.

Below is a description of the device and the principle of operation of the "Ugra". The engine for a walk-behind tractor made in China or in Japan (depending on the model) is started with an electric starter. The coupling of the power unit and transmission is quite strong.

Attached to them:

• opener;
• steering column;
• hitch for additional equipment;
• wheels (most often pneumatic);
• wings;
• cultivator replacing individual wheels.

Sometimes the complete set includes cutters and protective screens for them. To regulate the operation of the gearbox, a clutch is used. A power take-off shaft is used to transfer energy to auxiliary elements, including an all-wheel drive adapter or a simpler bogie. Since there are two such shafts, a wide range of equipment can be connected to Ugra. Only original spare parts are used for replacement.

The same gearbox, however, is made at a high professional level, which significantly reduces the need to repair the walk-behind tractor. The control elements are optimized for the highest ergonomics, providing comfort and safety during work.

Differences between individual modifications can be related to the following parameters:

• the width of the cultivation of the land;
• the number of cutters used;
• the total power of the motors;
• calipers;
• gear ratio.

Fuel is supplied to the engine through a carburetor, in which it is mixed with air. Initially, gasoline is in the tank, from where it is sent further by the pump. An important part of the fuel system is the air filter. If polluted air enters the motor, normal operation of the walk-behind tractor will be impossible. But when the fuel enters the combustion chamber, it must be ignited - at which point the spark plug comes on.

In addition to this candle, magnetic shoes, flywheels and magneto are responsible for the formation of a spark. The cooling system also plays an important role in the full operation of the engine. Rotating simultaneously with the crankshaft, the impeller on the flywheel creates air currents. They cool the cylinders. Gas distribution units, along with pumping fuel into the cylinder, help to remove waste products of combustion from it.

Together with the "Ugra" walk-behind tractor, you can use the "Zarya" mower. With the help of this device, they effectively mow the grass growing on pastures and personal garden plots, in vegetable gardens, on lawns. But there are two important limitations: the slope to the side should be no more than 8 degrees, and the slope of the terrain should be a maximum of 20 degrees. However, "Zarya" copes well with grain crops, with single thin bushes. Plants to be cut are placed in a row, aided by carefully thought out blade placement.

A more perfect version is Zarya-1. Such a mower is much more efficient. To drive the mower, energy is taken through a special shaft. To transport goods, you need to use a single-axle cart model "PMG300-1". This trailer is considered universal, while it can hold up to 350 kg of cargo. The highest permissible driving speed is no more than 9 km / h.

For motoblocks "Ugra", a potato digger of a roaring type is used. She is also able to extract other root crops from the ground. It is recommended to use the factory version of the potato digger. Such a device is as simple as possible in execution. Immersion into the ground is carried out to a depth of 20 cm, while strips up to 38 cm are covered.

Cutters, i.e. cultivators:

• crush the earth;
• loosen it;
• mix fertilizers and other agricultural reagents with the soil.

As for the lugs, in the factory version they can be equipped with cylindrical or hexagonal bushings. The cylindrical design is considered a classic solution, but the hex design helps increase traction and traction. In both cases, the lugs cannot be heavier than 18.8 kg. The outer section of the hooks for different types of equipment is 35-50 cm.

The weighting materials produced at the Kaluga plant weigh from 10 to 17 kg. The purpose of using such equipment is to increase sustainability and improve the quality of work in “difficult” lands. For the "Ugra" walk-behind tractor it is recommended to use branded plows "PM-1". With their help, you can perform various jobs.

The characteristics of "PM-1" are as follows:

• land grab - 21.5 cm;
• weight - 7.8 kg;
• dimensions - 53.5x31x41 cm.

The branded Kaluga hiller "RM-1" can weed beds, make furrows, and huddle the ground. When assembled, this structure has dimensions of 54x17x44.5 cm. The hiller is capable of covering a strip of soil up to 40 cm wide. Harrows placed on the "Ugra" will be able to cover strips up to 80-90 cm. The weight of the gun itself is 12 kg.

Motoblocks of the "Ugra" type can be supplemented with "SUN 1" snow blowers. Such a device effectively prepares clean and level footpaths even in snowy layers. For the snow blower to work, it must be connected to the bevel gear using a V-belt drive.

The snow blower weighs 47 kg and is capable of clearing a 60 cm strip with its blade in one pass. The maximum height of the snow layer removed once reaches 25 cm. Snow is thrown up to 5-8 m to the side.

It should be added that it is also useful when removing fallen leaves. The brush drive, like the snow blower, is a V-belt. The cleaning product can be rotated 180 degrees. An adapter is often attached to Ugra walk-behind tractors. Its parameters are 255x135x114 cm, its own weight is 240 kg. At the same time, they put 100 kg in the body, and 300 kg in the trolley. The only condition is that the total weight of the adapter with the load does not exceed 540 kg.

To make the adapter more comfortable, it was equipped with:

• band brakes;
• seat of large width;
• dismantled body;
• mechanism for attaching auxiliary units.

Earth drills are attached to the back of the walk-behind tractor. Usually they are hung on three-point mechanisms. Energy is received through the power take-off shaft.

From time to time it becomes necessary to remove the oil seal from the gearbox. It is usually associated with oil leakage. If you postpone work until a later date, it can jam the entire system.

Before replacing the oil seals, a number of actions are performed:

• turn off the motor;
• fix the walk-behind tractor in a stationary state;
• clean up spare parts;
• prepare a place where nothing will interfere.

Of course, the chosen site should be not only spacious, but also light. The gearbox is cleaned of oil. First, it is poured into a container, and then the remains are wiped off with a rag. The boot, and after it the oil seal, are pry off with slotted screwdrivers. After replacing the parts, the previously drained oil is poured back into the gearbox, and then the wheel is installed.

In order for the power plants of the Ugra walk-behind tractors to work properly, only impeccable engine oil should be poured into them. It is necessary to change the lubricant not only during routine technical inspections, but also in a number of cases known to all users. During the warranty period, it is recommended to repair the gearboxes of cultivators strictly in authorized service centers. Having found strong extraneous noise, tighten the bolts and change the gears. The clutch is adjusted in the event of any malfunction.

In general, users rate the cultivators of the Ugra series positively. It is especially noted that the clutch works well for the units. However, sometimes there are complaints of slow driving and loud noises. The gearbox raises a lot more complaints than the motor. However, walk-behind tractors of this line can work on lands of very different qualities.

Such devices are effectively used in any season of the year. "Ugra" plows open even areas densely overgrown with weeds. Users also give positive feedback to the steering wheels of motoblocks. All major parts of the machines have a long service life. Favorable opinions are also expressed about the functionality of Kaluga equipment.
