Mini-tractor Zubr model 12E: ideal for small farms

The Zubr minitractor has earned accolades from many owners. In general, all equipment produced by the Ukrainian company Zubr is actively used in farms of the former CIS countries. According to the features of the engine and its size, the bison 12e has become an ideal option for small farms, with a total area of \u200b\u200bno more than 4 hectares.

It was this tractor that became the embodiment of the ideas of many business executives who tried to convert a walk-behind tractor into an original mini-tractor. Zubr 12e represents a new class of tractor equipment - a motor-tractor.

Representatives of this class are walk-behind tractors in a past life, from which compact tractors were made at the factory. Factory modernization made it possible to significantly expand the capabilities of machines without spending a lot of money.

Purpose

The Zubr 12E minitractor is an indispensable assistant when working in small areas. The model is often used in vegetable gardens and fields, as it can be aggregated with a mass of various attachments. In addition, the equipment has no more weight and rather compact overall dimensions. The small weight of the tractor allows not to cause significant damage to the fertile soil layer during operation, and the compact dimensions provide the equipment with excellent maneuverability, making the machine most efficient when working in conditions with limited space.

Overview of Zubr mini tractors

The Zubr minitractors are in active demand among farmers in the CIS countries. The main advantage of this technique is considered to be high performance properties at a low price. The assembly of Zubr mini tractors takes place in China. The Zubr company controls the quality of manufactured products at all stages of production, which eliminates the possibility of producing defective equipment.

The Zubr minitractors are distinguished by their small dimensions and increased maneuverability. Due to this, they are mainly used for operation on small land plots with an area of up to 4 hectares. The model range of Zubr minitractors is equipped with motors with power from 8 to 24 horsepower. Mounted equipment greatly expands the possibilities of using this technique.

Attachment

The equipment of the Zubr 12E minitractor practically did not differ from the taken walk-behind tractor. The model was supplemented with a special set that allows the installation of such attachments as: a rotator, a plow and a meter-long working mill. All this equipment is already available as standard, when, in order to expand the scope of application, the manufacturer can optionally install other types of attachments, including a rotary mower, a shovel, a front blade, a hiller, a rotary plow, a potato planter, a potato digger, a brush, wings and shovels for the front wheels, special mower fasteners, as well as a front lifting mechanism that allows the use of loading units.

Description of technology

The Zubr mini-tractor has become the first factory product of this class, which is its main advantage over competitors' products. All parts of the unit were developed, manufactured and assembled at the Ukrainian enterprise. This had a good effect on the reliability of the tractor.

The basis for this model was the Zubr JR-Q 12 E walk-behind tractor, the most powerful in its class, which helped it perform various functions and work well with additional equipment. Instead of the three wheels that were installed on the walk-behind tractor, the mini-tractor will already receive four. The equipment was equipped with a driver's seat and a steering control system.

In terms of configuration, the mini-tractor is almost no different from its "big brother". It has a mechanism for aggregation with a rototiller, a plow and a working cutter, up to 1 meter long. The functionality of the equipment is increased with the help of attachments. Here the owner can install a mower, potato planter, hiller, etc.

Device

The device of this technique is characterized by maximum simplicity, which leads to excellent reliability. The basis is the frame, which has mounts for attachments in front and behind. Front and rear wheels of different diameters, as, indeed, is customary on any tractor. As already mentioned above, the steering is similar to that on Zhiguli cars. Mini-tractors based on a walk-behind tractor have a single-cylinder 12 hp engine, but larger machines are equipped with 2-cylinder 24-horsepower power units. There is a hydraulic pump for working with attachments. The clutch is dry double disc, and the brakes are drum.

The gearbox is mechanical and has two reverse and six forward speeds. Engine cooling water, which completely prevents any overheating. In order to be able to work with any attachments, hydraulic lifts are installed on mini-tractors, however, cheaper models still have mechanical mechanisms.

Device Features

The key advantages of this mini tractor are the following:

The compact overall dimensions provided the equipment with excellent maneuverability and allowed it to be used in conditions with limited working space.
Compared to the same walk-behind tractor, the Zubr 12E mini-tractor has more wheels.
The model is equipped with a full steering.
In order to provide increased comfort at work, the driver's seat has been significantly redesigned and improved.
The minitractor can be equipped with additional loads weighing 500 kilograms. They allow equipment to work more efficiently on hard and difficult soils.
The manufacturer offers a huge range of additional mounted and trailed types of working equipment, which can also be used on other models of mini-tractors.
A powerful engine for its class is used.

But in addition to the advantages, the Zubr 12E minitractor also has disadvantages. One of them is the lack of a hydraulic drive, through which mounted units are controlled. Another is the lack of a manual gearbox, which affected the comfort of work not in the best way.

The model is equipped with a single-disk, dry, friction clutch system, which is simple in design and durable. It also uses a V-belt drive located horizontally.

The tractor has a gear, combined eight-speed gearbox. It allows the car to move forward at speeds up to 23.5 kilometers per hour. And the highest speed of movement back is 6.97 kilometers per hour.

The Zubr 12E minitractor is equipped with a drum brake system that uses only one wheel. The design of the mini-tractor has a classic design, since this design is very easy to maintain.

In addition to the main attachments offered, the machine is also capable of using units from walk-behind tractors during operation. It is worth noting that at present, fakes of this mini-tractor are often found on the market. Some companies put forward Chinese equipment under the ZUBR brand, which differs little from the original car. But you can still recognize a fake thanks to the Zubr badge, which in the original version is made of metal. Chinese models, due to the high cost of metal, have a regular paper sticker.

Reliability

Development, manufacturing of parts and assembly of equipment is carried out at the same manufacturer's plant, which guarantees high reliability and quality of the manufactured machines. The mini-tractor, although it has a rather simple design, is distinguished by increased reliability and durability, due to which the operational life of the machine has been significantly increased.

Repair features

Distinctive features of this model are low maintenance and operation costs. This is due to the fact that most of the elements used are identical to the parts of walk-behind tractors, which allows not only to reduce costs, but also to facilitate the search, because if parts for a mini-tractor are not available for any reason, you can use walk-behind tractor units. According to this indicator, the Ukrainian model is one of the best in its class.

Advantages and disadvantages

This model appeared only in 2013 and, given its success, the Chinese began to make not only copies, but also analogues. The Ukrainians decided to pay more attention to testing equipment, which allowed the Zubr 12E tractor to gain a lot of advantages over competitors' products:

the dimensions of the tractor are comparable to walk-behind tractors. Adding to this the excellent maneuverability of the machine, it became an excellent option for use in hard-to-reach places;
4 wheels are installed on the equipment, and not 3, like a walk-behind tractor;
zero control system;
comfortable driving position;
a huge selection of attachments;
powerful, as for such sizes, motor;
affordable cost.

But the model also has some disadvantages:

lack of a hydraulic drive for adjusting attachments;
there is no tractor cab, which makes the work process dependent on weather conditions;
no front wheel drive.

Owner reviews

Recently, three of my friends in our village purchased these mini-tractors. Although our work is only seasonal, the purchased equipment quickly paid off the investment, thanks to the constant demand, low-cost operation and the possibility of doing maintenance with your own hands and improvised tools. I also have this tractor. Two and a half hectares of machinery processed without any complaints. At the moment, more than 1000 working hours have been wound and the mini-tractor is still working flawlessly.
At the expense of purchasing this machine, I thought for a long time, but at that time there was not enough money to buy. The year before last, on one of the sites I came across an ad for the sale of the Bison with a very affordable price. For use on a private farm, with an area of about three hectares - Zubr 12 may well be called the best option. Among the shortcomings I want to note the lack of a hydraulic system. On the other hand, mechanical control in relation to cheap onboard hydraulics is simpler and more reliable in operation. Well done designers, I will recommend the tractor to friends and acquaintances.
