DT-75M tractor - a car that has become a legend of domestic auto industry. Unlike other modifications, this technique has retained relevance and continues to be issued on the Volgograd Tractor Plant. According to statistics, the tracked tractor Dt-75 is the most mass technology in the USSR. In 2013, half a century anniversary took place from the beginning of the equipment.
Tractor DT-75M: Production History
Became one of best modelsmanufactured by the Volgograd Tractor Plant. The popularity of the machine for users is explained by the combination of acceptable operational and technical characteristics With a low cost of both the machine itself and its repair.
For fifty years of production, the DT-75M tractor device (reached to this day) has undergone significant changes. Technique has been modernized several times and improved. In 2009, the number of instances issued by the plant exceeded 2,500,000 units. In the same year, a new version of the car has descended from the conveyor. Dt-75m received a new hood, a cabin and a Finnish engine corresponding to high environmental standards. Today production power aggregates Naturally on the Volgograd Tractor Plant.
For a new restyled version, the manufacturer came up with a new name - "Agromash-90tg". The traditional red machine body was changed on blue with orange inserts.
Tractor DT-75M: Specifications
Dt-75m caterpillar tractor has a rich history, starting with the creation and ending with the latest modernization and change of name. The first models of cars were produced in the USSR and became a real breakthrough in the industry. The main purpose of DT-75M - agricultural work. The model with the designation "M" became the natural convergence of the DT-75 line. Technique belongs to the third traction class.
Engine
On the version of Dt-75 M, a 90-strong engine of the A-41 brand began to be applied. Later, the tractors were equipped with Motors D-245.552, known by various models Special machinery I. trucks. The rated power of A-41I is 94 hp / 69 kW, while D-245 gives 95.2 hp / 70 kW. Both power units are distinguished by inline cylinders. The frequency of rotation of the crankshaft when operating capacity is reached - 1750/1800 revolutions per minute, respectively. The needs of power units in nutrition are provided using a fuel tank of an increased to 315 liters of volume.
Four-cylinder engines are equipped with a liquid cooling system. The working volume A-41I is 7.43 liters. The volume D-245, in turn, does not exceed 4.75 liters. On the face of a noticeable reduction in the power spending of the machine. The newest four-stroke diesel due to fewer consumes less fuel. The specific consumption of fuel for motor A-41I is 226.6 g / kW * h or 166.6 g / hp * h. D-245 shows 220 g / kW * h or 161.7 g / hp * h. For particularly severe working conditions, the manufacturer has provided a torque margin within the coefficient of 15 and 25%, respectively.
In the latest models of tractors, in addition to the main motor, the preheater is provided, which launches the technique at temperatures below -5 degrees.
Transmission
DT-75M tractor gearbox does not differ from the initial modification. A seven-step four-step gearbox is installed here. The manufacturer offers an optional installation of a leader or reverse gearbox. The main part of the operation of the mechanism is performed by the gears of constant engagement. The checkpoint provides the speed of the tractor in the range of 5.45-9.3 km / h. The lower value of 0.34 km / h is achieved due to the installation of the track. Maximum speed DT-75M movements with a leader is 11.49 km / h. The reverse reducer allows the use of the tractor more efficiently, but does not affect the speed range.
Since the version has become one of the first continuers of the DT-75 lineup, the DT-75M tractor clutch device also did not differ from the original. Here is the dry single-tie coupling of a constantly closed type. The gearbox is mounted in a single housing with the rear axle. The rear axle works on two planetary turning mechanisms of a single-stage design. To ensure the stop, a belt type brakes are used. The mechanism works, both when moving forward and when moving back. The use of planetary gears made it possible to reduce the effort on the tractor turn levers, which, in turn, had a positive effect on the convenience of control.

The basis of the design is tracked chains that are attached on supporting rollers with rubber bands and are equipped with four balancing carriages. The width of each tracked chain is 390 mm. With an impressive mass, the tractor has a specific pressure on the soil within 47 kPa.
Cabin
The first DT-75 differed in minimal comfort. Later, new version Dt-75m was used updated, more convenient to operator cabin closed automotive type. To increase the viewing angle, the welded frame was pulled away a little to the right of the axis of the tractor. Wide viewing angles, high height, new plumage - all this was among positive characteristics new tight cabin. However, users began to complain about the impossibility of using the technique under the trees due to the height of the tractor, and the plant had to return the initial option.
Since DT-75M was intended for work in various climatic zones, the manufacturer provided inside the cab installation of heating equipment. To achieve acceptable working conditions for the operator, the plant also installed a ventilation mechanism that supplies purified from dust, cooled and moistened air. Installation turns on automatically when closing windows and doors.
