Motoblocks Zubr: overview of the model range

Who is the manufacturer

Zubr is a brand that represents the Chinese approach to agricultural technology. The Zubr walk-behind tractor is chosen by gardeners who prefer functional and reliable equipment. The equipment is produced at two Chinese factories (in the cities of Zhangzhou and Yangcheng). Here they make diesel and gasoline walk-behind tractors and cultivators, as well as attachments that expand the capabilities of motor vehicles.

The official one exports its products to Europe, Asia, and the American continent. All manufactured equipment meets international standards and has certificates of conformity valid in the West.

Advantages of Zubr technology:

• “Zubr” equipment is considered universal, since the Chinese manufacturer sells attachments;
• high quality components, they are available to Russian consumers;
• temperature changes that affect operation are taken into account;
• non-proprietary equipment can be used;
• any Zubr walk-behind tractor can be converted into a mini-tractor.

On a note!

The price of Zubr walk-behind tractors depends on engine power, design nuances, equipment, etc.

Purpose of the walk-behind tractor

The agricultural machinery produced by the Zubr company immediately gained popularity among customers for its high functionality, reliability and affordable cost. Further development of this direction was the development and production of the next generation heavy diesel walk-behind tractor, which was designated Zubr 12 or ZUBR JR Q12E according to the factory classification. The diesel walk-behind tractor Zubr 12 serves as a universal technical tool for agricultural work and is extremely necessary for small and medium-sized farms or private owners cultivating small plots of land (4-6 hectares). In these areas it is impossible or expensive to use conventional tractors, including their small modifications. In addition, this diesel model has high cross-country ability and long-term performance. By its design, any walk-behind tractor, including the Zubr 12 model, is characterized by the presence of only one wheel axle, on which the engine is mounted, providing the unit with the necessary energy. Any walk-behind tractor is equipped with a sufficiently large number of replaceable attachments that allow you to perform a variety of work. An important distinctive feature of this model is the possibility of using a special adapter with a seat, which actually transforms it into a mini-tractor. Operation of an agricultural machine in this mode and control becomes more convenient, and to increase comfort when working in adverse weather conditions, it is possible to install a cabin from a small YuMZ tractor on the resulting mini-tractor.

The manufactured JR Q12E walk-behind tractor with a diesel engine is capable of performing the following agricultural work:

• soil treatment on sites;
• plowing,
• harrowing,
• cultivation,
• hilling,
• planting and harvesting various crops;
• application of fertilizers.

In addition, using additional equipment for the Zubr 12 walk-behind tractor, you can perform the following work:

• mow grass and lawns;
• remove snow;
• sweep the area;
• transport goods.

To perform these works, various devices are installed on the agricultural unit:

• harrows;
• plows;
• cultivators;
• seeders;
• potato planters;
• cargo semi-trailers;
• fertilizer diffusers;
• brushes;
• snow blowers;
• mowers;
• rake;
• tedders.

Zubr models

The manufacturer produces two large groups of walk-behind tractors - those running on diesel fuel and gasoline. Agricultural technology differs in cooling methods. Lighter devices use air-cooled motors. Powerful and heavy units are equipped with water-cooled motors.

Diesel

The Chinese manufacturer offers several models running on diesel fuel. They differ in motor power, type of cooling, starting and cooling methods, and number of speeds.

PS-Q74

This walk-behind tractor has a four-stroke air-cooled engine. Motor power – 4 l. With. Dimensions: LxWxH, cm – 143x52x82, used for processing small plots of land and greenhouses.

Description of the Zubr walk-behind tractors

If you don’t know which unit to choose for yourself, you need to first decide on some points. First you need to find out what size your plot is. If your garden is only 2-3 acres, special equipment will not pay for itself. You can easily process such an area manually or take a closer look at very light electrically controlled machines. The same applies to caring for flower beds.

If your garden is 30-40 acres in size, then you need a powerful, heavy Zubr walk-behind tractor. As you know, all such equipment runs on either gasoline or diesel.

The first option will cost less, but the fuel itself is quite expensive today. Gasoline products are less powerful, but no less reliable. They are designed for smaller areas. A diesel walk-behind tractor is noisier and heavier, but also more durable, more powerful and reliable.

A diesel walk-behind tractor can cope with even the most difficult work; it can reach high speeds and transport huge loads. Moreover, it is precisely these models that are most often converted into mini tractors, which will make your work even easier and open up new opportunities.

You also need to decide for what purpose you are purchasing this agricultural equipment. If the walk-behind tractor will only be used for cultivating a small garden, then take a closer look at simplified gasoline models. If you have a large area with a difficult type of land, and you also want to take care of your garden plot, then choose diesel products.

Features of the Zubr walk-behind tractor:

1. Availability of spare parts. If it breaks, you can always buy and replace the damaged part;
2. The heavy unit is capable of cultivating soil on an area of ​​up to 2 hectares. In this case, the depth to which the land will be cultivated will be up to 30 centimeters;
3. Fuel consumption is minimal. This will allow you to work on the unit for many hours in a row without interruption;
4. The engine is air or water cooled, so you can work without problems even at high outdoor temperatures without fear of system overheating;
5. During use, you will have to control the tension less often thanks to the gear transmission and the presence of a disc clutch;
6. You can choose from two types of starter: electric starter or spring starter.

The Zubr walk-behind tractor in its category is considered not only one of the most highly efficient and multifunctional, but it has also displaced foreign analogues in the agricultural machinery market.

It is worth remembering that walk-behind tractors are not an alternative to tractors. Of course, they are capable of performing complex work on the ground, but they are not as powerful and multifunctional. However, you can always convert a diesel walk-behind tractor into a mini tractor yourself, and the attachments, the variety of which is simply amazing, can significantly expand the capabilities of the unit.

To significantly extend the service life of a diesel unit, it must first be run in. In the operating instructions you will find recommendations on how to do this process, what you should pay attention to and how to avoid mistakes. As a result, your technique will be able to show the best results in endurance and power.

Attachments

Thanks to a variety of attachments, Zubr equipment can be used for a wide variety of tasks. Devices that can be purchased in addition to the walk-behind tractor can significantly expand its capabilities.

Rotators

Soil tillers can perform several agricultural tasks at once, allowing you to simplify the process of cultivating the land.

Rotary cutter functions:

• plowing and soil cultivation;
• destruction of weeds;
• improves soil aeration;
• qualitatively mixes soil layers;
• levels the surface of the area;
• processes complex, floating soils;
• applies fertilizers for plowing.

offers two rototiller options - saber and crow's feet.

On a note!

The use of soil cutters allows you to effectively destroy not only annual but also perennial weeds.

Mowers

By attaching the mower to a mini-tractor, it can be used for cutting hay, collecting straw, and mowing lawns. Zubr offers three options for mowers:

• rotary;
• segmental;
• frontal.

Snow removal devices

In winter, thanks to special attachments, the walk-behind tractor turns into a snow removal equipment. Thus, the equipment does not stand idle in winter, but performs new, unexpected work.

The manufacturer offers three options for snow removal equipment:

1. Blade shovel. With its help it is convenient to remove thick snow.
2. Brush. Helps effectively clear the yard of light snow cover.
3. Auger snow blower. This device collects, crushes and throws snow, all in one working cycle. Typically, auger snow blowers are used to remove freshly fallen snow.

Plow

With the help of a mounted plow, Zubr walk-behind tractors plow the ground deeply and efficiently. It is used instead of rototillers to plow the soil to a significant depth - up to 30 cm. Plows can be double or single. The working width of units with double plows reaches 80 cm.

Lug wheels

Lugs are metal equipment that replaces pneumatic wheels. During movement, the lugs simultaneously loosen the soil. This equipment is usually installed on heavy-duty walk-behind tractors. The lugs make the mini-tractor heavier, facilitating better soil processing.

Potato planters

With the help of potato planters, farmers, summer residents, owners of vegetable gardens and personal plots can automate the process of planting potatoes. Attachments can significantly facilitate the process and reduce the time of planting root crops.

Potato planter functions:

• makes furrows;
• a special mechanism lowers the tubers into the furrows, maintaining equal intervals between them;
• covers the potatoes with soil and hills them up at the same time.

Potato digger

This equipment fully automates the process of digging up tubers. With its help, the tubers are removed from the soil, shaken off, and thrown onto the ground. There are two types of trailed equipment - vibrating and screening.

On a note!

Potato diggers can be used not only for collecting potatoes; they can be used to dig up beets, carrots, turnips and other root vegetables.

Hitch

A hitch is an element with which attachments and trailed equipment are connected to a walk-behind tractor. Most models are sold without hitches, so they must be purchased separately. offers a universal hitch with which you can expand the functionality of walk-behind tractors.

Adapter

An adapter is a kind of cart that consists of several elements: wheels, frame, seats. The adapter is attached to the walk-behind tractor using a hitch. It also has footrests and a brake lever. Thanks to the adapter, the unit turns into a mini-tractor with a seat.

The unit, equipped with an adapter, turns into a comfortable piece of equipment that makes hard agricultural work easier. Together with the adapter, other attachments can be attached to the walk-behind tractor - a mower, a plow, a milling cutter, etc.

Trailer

The trailed trolley is attached to the walk-behind tractor using a hitch. It is used to transport bulk or piece goods. It is convenient to use for transporting fertilizers, harvested crops, etc. The trailer is used in conjunction with an adapter - a person can operate a mini-tractor while sitting on a comfortable seat.

Hillers

Working body for processing loosened soil. With the help of hillers, you can not only hill up the soil, but also carry out other agricultural activities - weeding, cutting furrows for seedlings or planting tubers. It is convenient to hill up plants planted in rows - the working element, passing along the rows, moves the soil into the rows.

The main purpose of hillers is to hill up potatoes in order to increase the yield. There are hillers with fixed and variable soil coverage widths. There are models with wings and disk ones. The disadvantage of hillers is that part of the earth rolls back into the rut being made.

Weights

Weights help walk-behind tractors that are prone to slipping better cope with their functions. Weights, increasing the weight of the equipment, allow the cutters to sink deeper into the ground. They also stabilize work on sloping sites and hard soils, which simultaneously increases work efficiency and simplifies work.

Pneumatic tires

Wheels 4.00-8 are included. They can be attached to a trailer, mower, or snow blower. The wheel consists of a rubber tire, a tube and a collapsible disk. The wheels are suitable for working on the ground and for moving loads.

Crawler attachment

With a tracked attachment, the walk-behind tractor can move through swampy and heavy soils. Units equipped with tracks can be used in the off-season. The caterpillars move easily through the snow. A crawler walk-behind tractor becomes a vehicle - you can use it to get to a hunting or fishing spot.

Comparison with analogues

On the market, Zubr walk-behind tractors have a competitor that offers equipment at a similar cost - Centaur. This technique is also made in China.

Comparison of the Centaur and Bison equipment:

1. Among the "Zubrov" there is equipment with a capacity of 4-12 hp. With. The Centaurs have a maximum power of 13 hp. With.
2. Both manufacturers have models with petrol and diesel engines. In high-performance units, models of both brands have an additional electric starter.
3. Thanks to the PTO (power take-off shaft), any special equipment can be attached to the Zubr and Centaur walk-behind tractors. Both manufacturers produce a wide range of attachments - mowers, cultivators, etc.
4. The cost of “Bison” is in the range of 20-70 thousand rubles, the price of “Centaurs” is 16-65 thousand rubles.

Motoblocks "Zubr" are neither superior nor inferior to "Centaur" either in characteristics or functionality. Chinese technology shows good performance, is reliable and versatile. And compared to Western technology, Chinese units are significantly more expensive.

Engine

Motoblock Zubr 9 hp is equipped with a 4-stroke diesel engine Kama KM186F with a long service life and rational fuel consumption. The engine can be started using a decompressor or manually. The power plant meets European standards for vibration, noise and emissions, and direct injection makes it incredibly productive.

In the line of air-cooled diesel units that are equipped with Zubr walk-behind tractors, the Kama KM186F model is the most powerful version. The cast iron sleeve makes the motor more durable and allows you to count on a service life of up to 5000 hours. The unit is able to withstand increased loads, and the oil-filling air filter protects it from dirt and dust. Compared to gasoline analogues, this engine is more economical.

How to start

Before starting the walk-behind tractor, you must carefully study the instructions, especially the “Running in” chapter. First launch." If mistakes are made during the first start-up, the equipment may break down in the first hours of operation.

You cannot use the walk-behind tractor without running in the engine. After starting it for the first time, you need to break in the engine. This will allow small parts to rub in, and as a result, the equipment will avoid breakdowns. The motor starts to operate at low loads. Run-in should last from 5 to 20 hours. Attachments are not used during break-in.

The procedure for running the walk-behind tractor:

1. The walk-behind tractor is completely filled with fuel.
2. Oil is poured into the oil tank.
3. If the engine is water cooled, add water.
4. Lubricate all rubbing parts with oil.
5. Check the reliability of the fastenings.
6. Check the tension belts.
7. Turn on the unit at idle speed.
8. Allow the unit to operate at each speed. The duration of operation at speed is indicated in the instructions.
9. Check the brake system, steering, etc.
10. After running in, they move on to maintenance.

After the first start and break-in, you need to change the oil, and the walk-behind tractor can operate at full power.

Maintenance

For equipment to work properly, it needs maintenance. All steps are described in detail in the instructions.

Maintenance procedure:

• measuring oil and fuel levels;
• Change of oil;
• cleaning equipment elements from contamination;
• lubrication of rubbing parts - the names of oils are indicated in the instructions for the equipment;
• checking and tightening fasteners;
• once a month – technical inspection;
• diagnostics at the service center.

Attention!

To refuel gasoline models, use only high-quality unleaded gasoline - AI-92, and SE, SF, SG motor oils. For diesel models - SA, SV, SS, CD oil and high-quality diesel fuel.

When field work is completed, the equipment is preserved - dirt is removed, dried, gasoline/diesel fuel and oil are drained, rubbing elements are lubricated and, covered with a tarpaulin, placed in a garage or other dry room.

How to fix breakdowns

Motoblocks that are properly operated and undergo timely inspection are protected from unexpected breakdowns. If they are small, you can eliminate them yourself.

A common failure is the inability to start the engine. How to fix:

1. Spark plug problems. If it is burnt, wet, or smoked, the engine will not start. A burnt and wet candle is replaced, and a sooty candle is cleaned. The problem often arises due to an unset gap - it needs to be set.
2. Clogged filter. Needs to be replaced.
3. No fuel supply. It is necessary to check the fuel line - it may be clogged. If this happens, you need to replace the hose and clean the carburetor - in models running on gasoline.
4. The magneto burned out (converts mechanical energy into electrical energy). Needs to be replaced and adjusted.

Reasons for engine heating:

• low oil level;
• contamination of the engine or ventilation;
• foreign object entering the muffler;
• loss of spark in the spark plug.

Vibration of equipment indicates incorrect installation of cutters, damage or loosening of fasteners.

Reviews

Denis, 37 years old

At first I doubted the quality of the equipment, as I was confused by the Chinese assembly. As it turned out, it was completely in vain. I bought a JR-Q78, for some reason it was written - made in Belarus, although it is known that this is Chinese equipment. During the first year, the walk-behind tractor worked without breakdowns. A year later I changed the bearing, no more problems. I have been using the equipment for five years, it starts without problems.

Dmitry, 44 years old

I bought an 8 liter ZUBR walk-behind tractor. With. After running it in, I immediately attached the potato digger and tried it out on the field. The device is somewhat heavy to operate, so I am considering purchasing an adapter. There is enough power for work and transportation.

Land owners can choose a suitable Zubr walk-behind tractor. There are equipment on sale with different performance levels. To expand the capabilities of the walk-behind tractor, you can buy attachments.

As noted in the document dated March 30, 2020, three prototypes of gas turbine engines and seven pilot delivery ones were manufactured. Landing hovercraft project 12061 "Murena"

Weapons of the Fatherland

According to UEC-Saturn, the scope of application of the engines is as part of gas turbine units of hovercraft (HSC) of Project 12322 and boats of Project 12061.

As Mil.Press FlotProm was told at the Almaz shipyard in Feodosia and St. Petersburg, there are no corresponding orders for DCVP. According to the chairman of the board of directors of Almaz, Leonid Grabovets, talk about the production of Zubrov is still premature due to the lack of a contract and problems with a number of components.

In June 2020, shipbuilders told the publication that production of the Zubrov could be resumed in 2019-2021, depending on the timing of work on their main power plant.
In September 2020, Deputy Prime Minister Yuri Borisov said that in 2019 it is planned to order the Khabarovsk Shipbuilding Company. Moreover, their construction will begin in 2021; these plans are already included in the state weapons program.

The publication was unable to obtain a prompt comment from the KhSZ press service; a corresponding request is being prepared.

According to industry source Mil.Press FlotProm, the engines are intended specifically for Murens, since the exact date for the start of construction of the Zubrs has not yet been announced. In addition, he noted problems in the production of gearboxes for the gas turbine units of these ships.
