T-25 tractor: specifications, description, device and reviews

The T-25 wheeled tractor, whose technical characteristics we will consider today, first came off the assembly line in 1966 at the Kharkov Tractor Plant. Since 1972, it began to be manufactured at the Vladimir factory, for which it received the second name "Vladimrorets". In 1973, a version of the T-25A was created, with a more moderate "appetite" and took the place of the basic model T-25. The technical characteristics of the machine made it popular in all spheres of agricultural activity, where it is possible to apply a tractor of this class. Let's find out what is remarkable about this device.

Features

"Vladimirets" refers to the 6th thrust class, but its capacity is quite sufficient to perform a wide range of works in small farms. Depending on the type of additional attachments, the tractor can be used to solve such tasks:

1. Preparation of small fields for sowing and harvesting.
2. Carrying out of road and building works.
3. Works in gardens, greenhouses and vineyards.
4. Serve as a drive for the feeder.
5. Transport cargo and provide loading / unloading. Of course, he is not adapted to this as well as the 25-T mobile crane, the technical characteristics of which deserve genuine respect, but nevertheless. Do not forget that this is a device class 0.6.

The machine is executed according to the classical scheme: the motor is in the front part, and behind it there is a cabin. The rear axle is leading and equipped with larger wheels than the front. The tractor is relatively inexpensive and fully justifies its price. Therefore, it has become the most common machine for small rural farms.

Tractor arrangement

Model T-25, the technical characteristics of which will be given below, on the device does not differ from most tractors of this class. This can be quickly understood by the appearance of the apparatus and the layout of the main nodes. But there are unique features, which (or possessed at the time of release) exclusively "Vladimirets".

Body part

The carrier part of the tractor consists of two half-frames, a rear axle, a clutch of the gearbox and clutch. Wheel pairs can change the track width. On the front axle, it varies between 1.2-1.4, and on the rear - 1.1-1.5 m. This feature allows the tractor to carry out variegated work, including in cramped conditions. In order to increase the patency of the tires installed grousers. Another feature that makes it possible to operate the machine on impassable soils is a sprung suspension with the possibility of doubling the wheels.

Engine T-25

The technical characteristics of the motor allow it to be unpretentious in operation and maintenance, and also very economical. The two-cylinder motor mounted on the tractor is marked D-21A1. The power of the unit is 25 horsepower, in fuel consumption - about 224 g / kW * h.

Among the features of the engine can be noted a dual automatic lubrication system and unpretentiousness in terms of lubricants. The automatic lubrication system operates under pressure or by spraying. Fuel is supplied directly to the motor. Air cooling system. The engine is started by means of an electric starter.

Transmission

The mechanical gearbox in the T-25 tractor, whose technical characteristics we are discussing today, is reinforced with a reverse and doubling power. The tractor has eight front (two of them lowered) and six rear gears. The peculiarity is that the gearbox, the differential and the main gear are assembled in a single unit, which is called the transmission case. The machine has a permanent single-plate clutch of closed type. This circuit includes a power take-off shaft and a direct clutch.

Cabin

The hero of our conversation was arranged by a single cabin with two doors. The safety of the operator was provided by a frame, which reliably strengthened the workplace. Thanks to the wide rear-view mirrors and panoramic windows, the driver has an excellent view. The seat and the steering column can change their position. The range of adjustments is small, but the very fact that they exist is already worthy of respect for the tractor of those times. Comfortable work at any time of year was provided with a powerful system of heating and ventilation.

Optional equipment

Hydraulic system "Vladimirets" allows you to install on it up to 600 kg of attachments. For his work is responsible gear pump station. The tractor can be aggregated by cultivators, plows, semi-trailers, potato and beet harvesting devices, as well as bulldozer dumps.

The most widely used agricultural equipment installed on the T-25 is a single-hull plow. It is designed to work in small areas with a small run. The plow is mounted on three supports.

Tractor "Vladimirets T-25": technical specifications

In addition to the above, the machine has these parameters:

1. Dimensions: 2.8-3 / 1.37-1.46 / 1.3 m.
2. Weight - 1,5 tons.
3. The maximum speed is 21.6 km / h (in the sixth gear).
4. The maximum tractive effort is 0.7 tons (in the first gear).
5. Ground clearance - 43 cm.
6. The speed of the crankshaft is 1600 rpm.
7. The diameter of the cylinder is 10.5 cm.
8. The stroke of the piston is 12 cm.

Modifications

The T-25 was repeatedly upgraded. All models of the line did not differ from the basic version. The changes, of course, were, but very minor.

Below are the most noteworthy modifications:

• T-25A2 . Roughly speaking, this is a light version of the initial version. Changing the cab to the canvas awning, the designers were able to reduce the weight of the car. On the one hand, this increased the functionality of the tractor. But on the other - this measure excluded the possibility of using the device in the winter. For this case, designers have provided the opportunity to replace the awning on a metal cabin. However, as the reviews show, no one did this. Most farmers used the tractor only in the warm season. This is not a crane "Klintsy 25-T", the technical characteristics of which allow you to work all year round.
• T-25A3 . Creating this modification, the designers paid special attention to the safety of the driver. The cabin has a more reliable frame. Thanks to this, in case of overturning of the tractor operator could not worry about his health. At the same time, the case of this version received a more modern look.
• T-25K . This model was developed specifically to work in fields on which high crops grow. The power and functionality of the car remained the same, but its clearance was increased to one and a half meters.

Reviews

According to the feedback of the tractor operators, the T-25 model is a very reliable assistant in agricultural activities. He is thin, but very functional. A wide range of applications is determined by the modified track and high clearance.

If necessary, the machine can take on the function of the loader. Of course, it is not capable of showing such results as the Chetra T-25 bulldozer, the technical characteristics of which are simply amazing, but for that it is a mini tractor. In contrast to the main number of analogues, the "Vladimirets" can go back for a long time, without losing speed and traction. And the tractor is absolutely unprivileged to fuel and lubricants.

Without shortcomings, too, was not done. The most problematic part of the tractor is crankshaft. It is because of him that a large number of machines in this series are often written off into stock. Seals and studs of fastenings sometimes miss grease. If the tractor is used in tandem with the plow, it will be able to function only on light soil. For deep plowing, the machine does not have enough power. In winter, at sub-zero temperatures, the engine sometimes does not want to start. The reason for this is simple - the air cooling system. By the way, it was always considered a blot on the reputation of the domestic tractor-building industry.

Despite these shortcomings, many farmers preferred the T-25 tractor. Modifications, technical specifications, excellent price / quality ratio and versatility - that's what captivates this model.
