Cabin arrangement and controls

Salon MTZ-1025

The cab of the MTZ-1025 is metal, of a rigid construction, but with a large glazing area and good visibility, which distinguishes it favorably from the cabs of its predecessor tractors. Rear and side windows open. There are no "dead zones". The tractor is equipped with an additional pair of mirrors for improved visibility. There is a hatch in the roof, which plays an important role as a means of evacuation in case of a possible overturning of the tractor. It is also designed for additional ventilation.

The driver-operator's seat is of increased comfort, adjustable in three planes. Equipped with pneumatic damping system. Windshield wipers on the windshield and rear windows.

The tractor cab is distinguished by increased sound insulation due to the use of a large number of noise-absorbing polymeric materials.

Brake pedals - dual, with thoughtful ergonomics. The attachment control panel is located to the right of the steering wheel.

Analogues

This category includes models that differ from MTZ 1025 in engine power, the presence of additional or more advanced units. In particular, tractors of the MTZ 952, 892 and 1021 models may differ in the presence of a synchronized gearbox, running gear or additional power take-off shafts.

The analogue closest in performance is a rather expensive Chinese-made YTO-X904 tractor. The lower power of this car is compensated by the presence of a more advanced FIAT transmission and PERKINS engine. The traction capabilities of the Chinese counterpart are lower, however, the tractor can work with attachments designed for more powerful machines.

Attachment

For the MTZ-1025 tractor, it is recommended to use "native" attachments that fit it in the best way. His list includes:

Tractor MTZ-1025 with attachments

lifting equipment;
fertilizer spreaders;
plows and harrows;

cultivators, etc.

Attachment system for additional devices - three-point (three pairs of hydraulic outlets), traction - telescopic. Working hydraulic cylinders - two, located vertically.

The tractor supports three modes of operation: positional, power and combined.

Features of the device and operation

The MTZ-1025 tractor is equipped with a D-245 diesel engine, developed by engineers from Minsk. The engine has a four-cylinder layout with an in-line arrangement of cylinders. Supercharged, liquid-cooled four-stroke design – proven to be reliable and very efficient in harsh environments. Thanks to this, the machine is well adapted to domestic climatic regions. The engine received good performance by modern standards, and is considered one of the most economical internal combustion engines in its price category. As practice has shown, the D-245 is unpretentious in long-term use, however, like all motors of the family of the same name. The motor is undemanding to the quality of fuel, which is also an indisputable advantage that benefits the low cost of ownership - the motor perfectly "digests" both foreign and domestic diesel fuel, and also meets modern environmental standards.
The MTZ-1025 tractor is equipped with a synchronized manual gearbox, which has 16 forward and 8 reverse gears. This number of speeds is recognized as the most optimal, because the multi-stage gearbox operates almost silently, with minimal jerks and twitches when switching. The gears shift smoothly, and when shifting to a lower or higher speed, there are no serious noises or large power losses. Thus, the gearbox allows the full potential of the engine, namely its maximum power and torque. As a result, the maximum speed of the tractor is 37 km/h.
The transmission of the MTZ-1025 tractor is all-wheel drive, with a rear drive axle in the basic mode. The front axle can be connected forcibly, or automatically, as required by road conditions, as well as the degree of load. The rear drive axle is reinforced with wheel planetary gears, a self-locking differential, as well as reinforced axle shafts. The parameters of the rear wheels are 18.4R34. Thanks to all-wheel drive, center locks and large rear wheels with deep tread, it was possible to achieve excellent geometric cross-country ability. The machine is able to overcome absolutely any obstacles, including deep pits and ruts, fords, muddy ground and 30 percent climbs. In addition, unique features of the body and chassis contribute to high cross-country ability: high ground clearance, high entry and exit angles, minimal body overhangs, strong protection of the bottom and engine compartment.
The cab of the MTZ-1025 tractor is reinforced with a metal frame, which is a protection element in case of a rollover. Thanks to the frame, it was possible to prevent deformation of the body. In addition, we note the wide area of the front and side glazing, which guarantees a wide-angle view in all directions. The side windows can be opened to provide additional interior ventilation, which will provide coolness in the hot season. However, a full-fledged air conditioning is available as an option, and the basic package includes a heating system that creates heat in the cabin, which is very important at extremely low temperatures. Thus, comfortable work with the MTZ-1025 tractor is ensured both in warm and cold seasons. For additional interior ventilation, a hatch in the lid is also used. The front and rear windows are equipped with wipers. The cabin space is completely finished with plastic, which hid the bare metal, which made it possible to increase the atmosphere of coziness and comfort. The cab is sound and heat insulated, and is equipped with an air filter that cleans the dusty air that enters the cabin. The filter itself has a self-cleaning system, which greatly simplifies maintenance. All controls are located ergonomically and conveniently. For example, let's pay attention to the instrumentation located on the front panel. And the brake, clutch, throttle and shift levers are right in front of the driver's seat. The operator's seat, in turn, can be adjusted to your liking, based on the physique, height and weight of the driver. This also applies to the steering column.
The tractor is equipped with a hydraulic system, the design of which consists of two hydraulic cylinders with a vertical arrangement. Hydraulics has three modes of operation - power, positional and mixed. In addition, hydraulics allow you to fix attachments in the transport position. As for the linkage system, it is a three-point device, like many other modern tractors. The hitch is reinforced with telescopic rods, with which you can adjust the position of the mounted options. Especially for fixing wide-cut machines, additional phases are provided that allow you to better copy relief irregularities. To quickly attach attachments, you can use the CA-1 automatic hitch, which is available as an option. This hitch is mounted on a front or rear hitch. Please note that due to the simultaneous operation of the rear and front attachments, you can significantly increase the load capacity of the tractor.
Ease of operation and maintenance are the key advantages of the MTZ-1025 tractor when it comes to using the machine for many years. The technique was originally adapted for long-term use, and has a decent potential in terms of endurance and reliability. The quality of the products of the Minsk Tractor Plant has been improving over the years, and the cost of tractors is approximately at the same level as before. For the domestic consumer, the low cost of maintenance is one of the main criteria when choosing a tractor. If necessary, any spare parts can be found in the secondary market, or use the services of a service store and order the desired part. Delivery time is minimal due to the close economic and partnership relations between Russia and Belarus.
