Technical characteristics of the tractor T-25 (photo)

Old, but reliable tractors T-25 have successfully coped with agricultural work for 50 years and are ready to give odds to many modern representatives of agricultural machinery. The possibility of installing various attachments causes their versatility and partly popularity.
The dimensions and technical characteristics of the T-25 tractor make it possible to plow light soils, process agricultural crops, transport small loads and work with various types of attachments.

Tractor Construction

The copies of the T-25 range are universal wheeled tractors with a load class of 0.6 and with a drive to the rear wheels. Agricultural equipment is equipped with a four-stroke two-cylinder diesel unit with air cooling. The mechanical gearbox of the reversible type has the possibility of mounting the automatic coupler and the rear power take-off shaft. To disclose the technical characteristics of the tractor T-25, it is necessary to describe each mechanism. Now let's move on to the cockpit.

The tractor cabin, depending on the modification, can be represented by a conventional frame structure, safety cage or a tent. Any type of it is single, two-door and quite comfortable for long work. The presence of heating and light devices and an effective noise isolation system favorably distinguishes technology. Airing the cabin is possible in a natural way and with the help of a filtration unit. The ability to adjust the steering column only increases the comfort level when operating the tractor.

Main technical characteristics

A wide range of tasks that can be solved with the help of this agricultural machinery, determine the technical characteristics of the T-25 tractor:

• Maximum working power - 20 horsepower, or 14.6 kW;
• Specific fuel consumption - 223 g / kW * h, or 164 g / hp * h;
• Total weight of the model - 2020 kg;
• Number of front and rear gears - 6;
• Speed of movement - 25 km / h;
• Tractive effort - 800 kg;
• Carrying capacity - 600 kg.

The characteristics of the tractor depend on the model and the year of production. All representatives of the line are equipped with diesel unit D21 or its modification D21A1.

Engine characteristics

The first models of tractors (1966 of release) were equipped with diesel power plants D21. It's almost impossible to meet such motors now. The most widespread engine was D21A1.

Lubrication system with automatic regulation of the thermal regime is a distinctive feature of the new generation of motors installed on the T-25 tractor. The technical characteristics of the engine D21A1 were significantly different from the previous engines. High durability of the diesel unit was provided by a four-stage air purification system. Atmospheric air was sucked into the cylinders through two filtering, one dry-inertial and wet-contact plants. Fuel, before getting into the engine, passed through filters of coarse and fine cleaning.

Transmission

The basis of the tractor transmission system is a 12-band reversible manual transmission. A distinctive feature of MKPP is the presence of two slowed-down gears for moving forward. The clutch of the model is a single-disk, closed, constant type. In the rear part, a power take-off shaft could be installed, which significantly increased the technical characteristics of the T-25 tractor. Moreover, all modifications were equipped exclusively with a separate-unit hydraulic design with an independent drive of the hydraulic pump. The rear axle was equipped with a differential, which significantly increased the patency of technology on heavy ground.

Features of the chassis

Suspension of agricultural machinery is made of hardened steel, it has high wear resistance and high strength. The basis of the running gear is the front and rear axles. The front axle consists of pivoting cams with axles, rods, front wheel hubs and steering gear levers in the form of a trapezoid, as well as a rocker. The last element is made of high-grade steel, in its middle part has tides with pressed bushings. The taut front axle rests against the fastening of the half-frame.

Would not have a T-25 tractor the technical characteristics of the patency so high, if not for the driving rear wheels, which more than other elements deserve attention. Their basis is a disk of steel with a profiled rim and stamping. The tread pattern of the tire is designed in such a way that it is self-cleaning during operation and increased grip of the wheels with the surface.

Modifications

Production was established in 1966 at a tractor plant in Kharkov. At that time, the T-25 tractor had rather high performance indicators, the technical characteristics of which could not but rejoice. This led to the demand and further development of technology. Later, the copies were produced at the Vladimir Tractor Plant. It was there that the main modifications were designed. T-25A1 became the main modified model. The basic equipment practically did not differ from its prototype. The only exception was the engine, which now produced 25 horsepower (18.3 kW).

The copies of the T-25A2 differed by a modified cab, which was now equipped with a tent. Obviously, this model was used to work in warm regions of the country. The T-25A3 tractor was distinguished by the presence of a safety cage, which increased the longitudinal stiffness of the body and was supposed to provide the driver's life space in an accident.

Analogues in Russia and in the world

Model T-30A8 - the main analogue of agricultural machinery, which confidently superseded and displaced from the market tractor T-25. Technical specifications, tank size, all-wheel drive layout, more powerful engine and improved steering allowed the T-30A8 to occupy a certain niche in agriculture.

Another analogue of the tractor is called copy T30-69, which does not stand out from the representative described by us. Foreign analogs can be called Chinese mini tractors FT-254 and FT-254, Fengshou FS 240. In addition to increased reliability and the availability of more modern units and units, these models are practically the same as the domestic T-25.

In conclusion, it should be said that both the technical indicators and the characteristics of the T-25 tractor, the photo of which is presented in the article, make it a universal assistant for performing any agricultural work, as well as for solving tasks of transporting materials, cleaning the territory and performing construction work. Quite high characteristics of this technology have ensured its stable demand in the market.
