The machine actively works on construction sites, operates in the agricultural sector and various industries. The bulldozer works successfully on small slopes. Excellent cross-country ability makes the car indispensable for off-road, heavily swampy soil. Additional accessories increase the functionality of the unit.
Bulldozer DT 75 is a great off-road assistant
The DT 75 bulldozer has been produced by the Volgograd Tractor Plant for almost 50 years. During this time, the equipment went through multiple modernizations and restylings. Designers are constantly working to improve both performance characteristics and the comfort of the driver’s workplace.
DT 75 is equipped with tracked traction, which gives it very high maneuverability. The equipment was specially developed for use on off-road and swampy areas. The scope of application of a bulldozer is very wide: from construction to clearing roads of snow and various agricultural needs.
Options for quality attachments
A wide variety of attachments can be installed on this bulldozer. It all depends on the goals set, as well as on the general features of the work.
There are parts that are used for use in agriculture and for clearing snow . A stationary or special rotary blade can be used as functional attachments.
A bulldozer of this brand guarantees complete safety and reliability of the attachments used and the running system as a whole.
Classification of roads by type and condition of the road surface:
Then he unscrewed the locking plates of the brake drums, they went very badly, he broke one off and hooked it on the round nuts with a mounting tool, while his partner moved the brake drum and pulled out the shaft along with the axle shaft. If several pairs of gears are involved in the transmission, then the total gear ratio is obtained by multiplying the gear ratios of all pairs of gears involved in the transmission. Different speeds of the tractor and the car at a constant engine speed are achieved by changing the gear ratio between the engine shaft and the drive wheels or sprockets.

| Tractor DT-75 technical characteristics, price, photo, video Can be used as an energy source for the installation of various industrial and agricultural equipment, including the installation of the NKF-54 rotary flange pump. But if expenses for fuels and lubricants are associated with the production of goods, works, services, then they will be classified as expenses in the period of recognition of income for such goods, works, services. |
| Diesel fuel consumption rate for Tractor DT 75 For aggregation, DT-75D uses a hydraulic control and drive system, towing device, rear linkage, power take-off shaft and removable front ballast weights. When calculating, it turns out that for a line with a working condition, the percentages of the working condition and the seasonal allowance are added up, and then multiplied by the base rate per engine hour, although in theory the load rate should first be calculated, and then the seasonal allowance should be applied to it. |
- A working stroke in which the soil is deepened and dug (the collected soil is collected and then moved).
- Stopping movement at the moment of switching gears.
- Idling time to return the unit to the starting point.
- The stop required to switch to the working stroke.
Attachments
Tractors of the DT-75 family are equipped with front- and rear-mounted attachments.
The following equipment is available for the machines:
- bulldozer blade with fixed and rotating blade;
- a drilling rig with a fixed drill diameter for working on soil without crushed stone or pebbles;
- drilling station with replaceable drills;
- installation for laying trenches;
- earth-moving cutter for frozen soil;
- soil loosener with 3 working teeth;
- rotary snow blower;
- pipelayer;
- mobile welding station;
- pumping unit;
- sprinklers.
When working with a plow on the DT-75, equipment from other tracked vehicles can be used. The attachment is carried out to 2 or 3 attachment points on the rear of the tractor. Before adjusting the plow, the tractor must be placed on a flat surface and the technical condition of the components and the fixation of the hitch must be checked.
Setting the plowing depth on the plow is as follows:
- Place the tractor on boards with a thickness equal to the planned plowing depth minus 20 mm (the depth of soil subsidence when moving).
- Put the plow into working condition.
- Set the plow parallel to the ground using the right brace and top link.
- Set the depth with the reach of the plow support roller strut. The wheel is placed on a stand with a height equal to the plowing depth minus 25 mm (compensation for subsidence of the wheel into the ground).
- Tighten the position clamps of the support wheel stands.
Do-it-yourself blade
The blade consists of a frame, a working surface and a hydraulic cylinder. Ready-made units or a channel with additional reinforcements are used as a frame. The blade is made of steel sheet 8-10 mm thick and is additionally reinforced along the rear surface. The homemade structure must withstand heavy loads encountered during operation. It is possible to install a rotary blade controlled by a separate hydraulic cylinder. Hydraulics are controlled from the operator's cabin.
