The seat is located above the right caterpillar, which is perfectly visible to the furrow.

To reduce the noise, the manufacturer was installed by noise insulation. The side and the upper disturbance of the cabin have special plates that play the role of thermos cards.

In summer they don’t miss the heat and cold in winter. The glasses are also tinted to prevent a light sunlight in the operator’s cabin.

In the tractors of DT 175 and 175C, a power selection wave is installed on the back of the gear. All attached and excluded devices are associated with this.


The tractor DT 175 Volgar has achieved great popularity due to high technical features and improved cros s-country ability.

It is also used under the most difficult conditions and on heavy soils.

The Caterpillar Tractor DT 175 is used for plowing and shocking heavy virgin areas, which is used as a bulldozer for leveling sand grains mixtures and for snow removal, rubbing wood from the location of the log house and for transporting heavy supporters.

You can also find reviews in the forums if the Volgar tractor was used as an excavator.


Before the DT tractor 175 goes out fully, the Volgar must be examined by operating instructions.

This will help to understand the principle of machines and the rules for maintenance.

Despite its large weight and impressive technical properties, the tractor DT 175 Volgar is easy to maintain.

  • In order to increase the lifespan of the tractor, it is necessary to operate it in such a way that all details violate and get into the grooves. The procedure takes about 8 hours. At this point, you can only charge the engine at half of its performance. Replace the engine oil at the end of the procedure.
  • If you don’t want to use the tractor for long, you have to clean it, use it in a dry place, let oil and gasoline drain, separate the spark plugs and grease the parts so that no corrosion forms.
  • Engine oil should be changed every 100 hours. Soviet oils according to Gost are best suited for the bay: M-10G2K or M-10DM.
  • The gear oil should be changed after 1,000 rolled hours. TAP-15V is used for replacement.
  • Tractor motors dt 175 Volgar optowel fuck. They differ in the quality of the fuel, but so that the engine is served as long as possible without failure, it is necessary to use a clean and fresh diesel.

Basic malfunctions and repairs

One of the characteristic features of the caterpillar tractor is their simplicity of the design, they have nothing unnecessary and all details are on an intuitive level. To repair most of the breakdowns, there is no need to have special skills. It is sufficient to simply examine the operating instructions.

The engine will not start: Lack of oil or fuel; Dirt entered the air or fuel filter; The light of the ignition does not give a spark; The carburetor is not configured correctly
Excessive vibration comes from the tractor: The presence of fuel and oil; Fixing fastening elements on the device; Fastening
Brakes do not work: The free hub of the pedal has increased (adjust its position); The brake disc or the block was worn out (replace the corresponding details).
If the hydraulic system does not increase the appendix: There is not enough oil in the hydraulics (it is necessary to bring it into the desired brand). The hydraulic system pump is in the AUS status (you should switch on). The safety valve sees (you have to disassemble it and clean it).
Starter does not work: Break or bad contact of the wire (soldering or pairing); Battery charge weak (charge); Short circuit (replace or brush the surface of the collector); Bad contact of the magnetic switch (turning switch hub by 2-3 revolutions).

Owner reviews

The following write the following those who managed to get to know the tractor dt 175 Volgar in action, in thematic forums:

Alexander: “In 1990 I bought a tractor that I worked successfully on for 20 years. And he fulfilled its purpose with all might. The box has never been broken down for repair. I undermined the drums a few times and changed the ligaments. In the course of time, he set up the engine: he made the fuel injection a little earlier. This increases the engine output before our eyes. Now he is already taking a wel l-deserved break, the engine is dead and the chains are torn too often, although the gear and the hydraulics can still be expanded for sale.

Owner reviews

Ruslan, 49 years old:

“He worked before the collapse of the Union for DT-175 and found this monster of the Soviet tractor building. The car is strong, hardy and unpretentious in care. Of course I broke more than once, but there were no problems with the repair – spare parts were available and succumbed to repairs faster. Despite the promised sound insulation, it often had to use Berushi. The engine was overheated in strong heat, I had to stop. The starter saved in winter, but I had to sweat a lot. The series of functions is impressive, the hydraulic system has simplified management and facilitates and works with the units that have been stored. “

Nikolai, 54 years old:

“I bought a cheap tractor DT-175 at the end of the 1990s. He opened his construction companies, such equipment was necessary. After that, the tractor worked for another 8-9 years, pulled the blocks, pitches, pitches, etc. Then he still couldn’t stand it and fell apart: caterpillars, engine and others. I also did not stay here: what I sold on Chermet, which is on spare parts (what lived). “
