Crawler tractors - tested assistants. Crawler Tractors - Tested Assistants Options for Attached High-quality equipment

What dimensions will have a tractor tractor Dt 75 depends, first of all, from its modification. So, for modern models The following indicators are characteristic:

• body length - 4240 mm, in combination with rear hinged equipment in a position, ready for movement - 4530 mm;
• hull width - 1850 mm;
• the height is 2705 mm, it may vary within 30 mm in both directions.

Tractor mass indicators depend on the type of established power aggregate. For models with the Motor A-41, it is 6530 kg, and for representatives equipped with a diesel installation of D-245.5S2 - 6000 kg. The technical characteristics of the tractor Dt 75, namely the production mass, changes depending on the type hinged equipment.

Cabin

Comfortable conditions for the driver's work provides a modern cabin. In its composition, it has a heating system, which allows you to work in winter time. To quench the engine vibrations and the other construction machinery The vibration insulation material in the compartment with waterproofing is laid.

Observation of the workflow will not prevent any weather conditions, for the cabin is equipped with an front and rear wiper, which is able to remove and thin layer of the land, as well as the glass washer. The progressive tractor for work in the summer is equipped with air conditioning.

Constructive features

One of the significant constructive features Tractor DT 75 first years of release is the system of launching a diesel engine. The values \u200b\u200bof the unit do not allow the motor to start using an electric drive. So the start is responsible gas enginewhich is already activated by the electric starter.

Another feature of the models can be called a pre-fit heater of diesel fuel, which turns on operation at ambient temperature is less than -5 degrees Celsius. If necessary, in particularly low operating facilities, an agricultural tractor DT 75 may be equipped with a leader.

Scope of application

The scope of the use of the tractor is quite extensive. He has proven himself well at the construction site, especially during the creation of large catlers for massive objects. It is possible to move the soil masses with dragging by means of a direct dump. For the loading of the Earth, spherical dumps are installed in dump trucks on the models.

Often the heavyweight machine is used as a tractor for transporting particularly massive objects. In this case, it is equipped with a pendulum or rigid trailer device. But Dt 75 is not in vain as an agricultural tractor. Among the attached equipment there are elements, for work in the field - seeders, potatoes, plows, bars, harrows.

Cost

The cost of tracked tractors varies significantly depending on the region. At the moment, the bulldozer market is most presented former models. Their price begins to grow from 250 thousand rubles and depends on the state, technical Equipment And year of release.

The factory models of modern years of release (2016) costs begins to grow from 1.7 million rubles. But the most promising remains modified in 2009 tractor DT 75. Its price corresponds to power and reliability, will satisfy any customer who is counting on durable techniques.

Crawler Agricultural Tractor DT-75 Kazakhstan is the most massive and hardy technique since the USSR. It began to be released in the 60s. The prototype of the technique was produced in Volgograd (on VTZ). It was a legend tractor, without any Soviet film about raising virgins. For the needs of agriculture in Kazakhstan, a high-quality equipment was needed. To this end, a Pavlodar tractor plant has been built. Lenin, where they began to produce the famous tractor Dt-75m Kazakhstan. The first unit came down from the conveyor of the Tractor Plant in 1968 - it was the famous DT-75 of Kazakhstan.

Description of tractor DT Kazakhstan

During the long years of production, the tractor has changed more than once. Despite this, the car to this day has retained a simple design. During all these years, a variety of models were released. More than once changed the design of the tractor cabin. It was rounded, convex, shifted to the right, angular, etc.

In general, when choosing a tractor, it is customary to divide the cabins on 3 types: a small (round), "postman" (tank with side), "Kazakhstan" (large glass).

The change in the appearance changed and the technical characteristics of the machine.
The DT-75B model was designed for unstable soil. It was enlarged caterpillars and a motor changed.

The DT-75K tractor was modified for unstable work on steep slopes. When working on such surfaces, the system was protected from tipping.

DT-75C model was used as a bulldozer thanks powerful motor From 6 cylinders.

DT-75 ml tractor had a different coating motor compartment, a large cabin cabin, which increased the height of the car.

Currently, the DT-75M model is used. This is a general purpose technique that has a thrust class 3.

Description and technical characteristics of the machine:

1. Engine and KP. At the beginning of the tractor, a 4-stroke and 4-cylinder diesel engine was established - SMD 14, the power of which was 75 liters. from. The motor was equipped with liquid cooling. In the DT-75m model, the A-41 motor was supplied (90 liters with.), Dt-75N - SMD-18N (95 l. P.) With turbocharging.
2. In order to launch diesel, an electric starter is used. There is also a PZB-200 heater, which is used under conditions of low temperatures (below -5ºС), as preheating. Motor has 15% of the torque reserve at a working volume of 7.4 liters.
3. The diameter of the cylinder is 13 cm, and the move is 14 cm. Diesel fuel is used as a fuel. The launch of the mechanism is performed when mixing gasoline with engine oil. The fuel tank is refilled by 315 liters.
4. DT-75 tractor forward moves at a speed of 11.18 km / h, and back - 4.54 km / h. Manual gearbox, has 7 steps. Clutch coupling - dry, 2-disk, constantly closed type.

The unit is assembled on a welded frame, which also contains nodes and mechanisms. Braking is ensured by the rear bridge. To do this, there is a braking system and 2 turning mechanism with a 1st stage.

In the hydraulic structure, a shaft, which makes 540 and 1000 rpm. Mechanical system For hinged equipment the same for tractors Dt-75 and Dt-75ml. This is a standard type of agricultural machinery system that can work with any units, including a bulldozer and a trailer.

The cab is made of a solid sheet sheet, therefore it is sealed. Inside there may be 2 people. The driver's seat can be adjusted at its discretion. Inside the cockpit, the ventilation system and air purification system is mounted. It works independently, immediately after closing the door of the cabin.

The weight and sizes of the tractor

Consider how much an aggregate weighs. Weight depends on the model and the modified modifications. It is easier for all DT-75 - its weight varies from 5900 to 6050 kg. The mass of the tractor Dt-75m is equal to 6550 kg, other models - up to 7200 kg.

Dt-75 tractor is a tracked car, which was produced in the Soviet Union since 1963. The technical characteristics of the tractor allowed it to perform various production tasks. The second generation of these machines received even more power, which made it possible to significantly expand the functionality of the technique. Dt-75 tractors were produced in Volgograd and in Kazakhstan.

Due to the powerful power plant, the tractor could be used as a bulldozer, to perform the function of the tractor and apply to plowing the fields. Small weight and wide tracked canvas, provided cars good permeability and maneuverability. Thanks to these features, the DT-75 tractor is most widely used for field work and on logging.

Device machine

The first models of DT-75 were installed four-cylinder diesel engines of the SMD-14. These aggregates issued power in 75 horse power And possessed a working resource in 3000 hours.

Subsequently, the power plant was replaced by an improved engine from this SMD-14NG series. New Motor possessed the same technical characteristicsAs his predecessor, but betrayed more power - 80 horsepower.

For the operation of equipment in the regions with a cold climate and work in winterThe engine of cold starting engine was provided. In the history of its existence, the tractor was modified several times. For the second generation of machines, more powerful diesel units were installed.

The base for the DT-75 tractor serves a metal composite frame. It consists of two spars, which are interconnected with metal pipes. The main nodes of the tractor are attached to the frame: roller mechanisms, suspension, tracked trolleys, blocks of guide and leading rollers.

The transmission of the machine consists of a four chassis gearbox, a two-way clutch clutch of a closed type and ribbon floating brakes. The gearbox provides 7 front and one rear speed.

To increase traction indicators, a stroke decrease was installed on the tractor, a single-stage reverse gearbox and a planetary gearbox to increase the torque. It was these features that allowed to install dump and use the machine as a bulldozer.

Installed on the caterpillar tractor and the Power (power takeoff shaft), the drive was driven by a leader and whether the reducer to increase the torque. By the way, these nodes were mounted on the front wall of the gearbox, but were highlighted in a separate unit.

DT-75 tractor had a double tight cabin. High tightness ensured protection against noise and dust. Driver chair has the opportunity to change your configuration. For comfortable work, ventilation and heating systems. The safety frame was responsible for the safety of the driver.

Various target units can use as attachments to the DT-75 tractor. This contributes to the trailer, the rear hood and the hydraulic system of separate-aggregate type. This gives the machine the opportunity to use a plow, a bulldozer, a seeder of the harrow and a device for cleaning potatoes.

In addition, the car can be aggregated with additional equipment side semi-mounted type. This allows you to turn the tractor into a concrete-layer or loader. A wide range of DT-75 capabilities includes road, construction and drilling work.

Overview of modifications

Dt-75 tracked tractor, became a prototype for a whole model Row. Machines produced in different timeBut in each version the designers made noticeable improvements. Consider the most outstanding machines from this series.

Dt-75m

This tracked tractor was produced in Volgograd and Kazakhstan since 1967. The car has changed noticeably appearance. This manifested itself in installing a higher cabin, which, unlike the basic version, shifted to the right.

On the left side of the cab was mounted fuel tank. Manufacturers added to it volume and he began to accommodate 315 liters of fuel. Such a need was caused by installing a more powerful engine - A-41, with a capacity of 90 horsepower.

Dt-75b

The car was designed specifically for work on wetlands. This tracked tractor was produced by the Volgograd plant and was used in the peat mining sites. In connection with such a narrow specialization, the designers made the following changes.

The width of the caterpillar canvase was increased. This made it possible to significantly increase the passability of the machine. In addition, such a decision reduced the pressure of the equipment to the ground. For comparison, the base DT-75, this indicator was 0.44 kg per centimeter square. Dt-75b these data decreased to 0.24 kg per centimeter.

Changed the power plant, began to be used diesel engine SMD-14ng power in 80 horsepower.

In connection with, work in difficult conditions, the frame was supplemented with pallets to protect the engine and transmission from mechanical damage.

Dt-75K.

The tracked tractor was intended for use on steep slopes, the angle of inclination could reach 20 degrees. Thanks to constructive refinement, the car found its use in the mining industry. Chassis It was completely copied with Dt-75b. It provided the car a reliable grip with the soil.

As power plant A diesel unit of SMD-14MG was installed. To reduce the risk of overturning the machine when working on steep slopes, a safety system was developed and installed.

The tractor I. was distinguished internal device Cabins. It was double, the seats were installed not near, but opposite each other. The position of the tractor was monitored visually using the roll pointer.

Dt-75s

The target destination of this technique of agricultural and road works. Of the features, you can note the six-cylinder turbocharged engine of the SMD-66 series.

The power of the unit was 170 horsepower, the speed of rotation is 1,900 rpm. In addition, the car was equipped with a resistance torque converter. These features allowed the car to be easily transformed into a bulldozer.

Dt-75 crawler tractor was produced on a wheelchair. Several such cars came from the conveyor of the Kazakhstan plant. The technique was produced by limited series and was used mainly in agriculture. The wheel base was obtained by cars: Dt-75 MLC, DT-75DK, DT-75KP and DT-75kPM.

In 1998, the tractor plant, located in Kazakhstan, announced his bankruptcy. Currently, the tracked tractor DT-75 is produced only in Volgograd under the brand name "Agromash 90TG". An 94-strong diesel engine A-41SI-02 is installed on the machine, with a rotational speed of 1,750 rpm. Like all predecessors, the technique is intended for multipurpose use.

Advantages and disadvantages

Dt-75 tracked tractor is a truly powerful and functional machine. Timing technique Soviet Union, it copes well with modern tasks.

The small weight of the machine and extremely low pressure on the ground allows you to use the machine on the fields, without fear of damage to the fertile soil layer. All modifications of the machine are characterized by economical fuel consumption, reliability and ease of operation.

Of the flaws, you can note the frequent failure hydraulic pump And the incorrect operation of the built-in generator. As with most Soviet cars, it is possible to observe the flow of oil through the gland seals.

DT-75 tractor is a common-purpose tractor used in agriculture. This model He is the most popular Soviet caterpillar tractor. At the end of 2013, more than 2,741 million units of this technique were manufactured. The tractor is intended for use in an aggregate with trailed hydraulic, semi-mounted and mounted machines at road, reclamation, earthmoving and agricultural work (synchtercing, plowing, cleaning and sowing crops, cultivation and harrowing).

Good reputation of DT-75 acquired thanks to the excellent combination of a small cost and operational properties (maintainability, versatility, efficiency and simplicity). Production of this model began in 1963 at the Volgograd Tractor Plant. Because of the large demand for the tractor since 1968, it began to produce it at the Pavlodar Tractor Plant. In the initial version of Dt-75, it existed for quite a long time, after which the model was repeatedly subjected to modernization and restyling.

The tractor was produced in 4 sets:

1. Dt-75-C1 - with nodes of the hydraulic system, remote cylinders and the rear hide.
2. Dt-75-C2 - with a dispenser, hydraulic pump, oil supplies and a tank of the hydraulic system.
3. DT-75-C3 - without rear suspension and hydraulic systems.
4. Dt-75-C4 - with a rear jacket, nodes of the hydraulic system, but without remote cylinders.

Modifications of the model were created a huge set. Among them, DT-75V, who received the Motor of the SMD-14ng, its marsh version of DT-75BV; DT-75MV and DT-75M with A-41 unit; Dt-75d with the engine A-41 and its peat modification of DT-75DT; DT-75N with the Motor SMD-18N, its swamp modification of DT-75NB, as well as DT-75RM with the RM-80 aggregate.

The last update of DT-75 occurred in August 2009. After restyling, the model received an eco-friendly and economical SISU engine, manufactured by Finnish technology at the Vladimir Motor Tractor Plant, a new cabin and a plastic hood. In the Volgograd Tractor Plant decided to change the corporate colors of the tractor. Instead of the red, it became white-blue with orange inserts. The model name has changed. Selling tractor steel under the name "Agromash 90TG".

Rated engine power DT-75 - 58.8 kW, rotational speed - 1800 rpm. For rated power Fuel consumption is 251.3 g / kW * h. At the same time, the tractor functions exclusively on diesel fuel. Starting the starting motor is carried out on the mixture motor oil With gasoline A-72 (A-76) in the ratio of mass 1:20. The fuel tank of the model accommodates 315 liters of fuel. DT-75 movement track is 1.33 meters, ground clearance - 0.376 meters, longitudinal base - 1.612 meters. The indicator of the specific pressure on the soil is 0.049 MPa. dimensions Models: 3480 × 1890 × 2650 millimeters, weight - 6440 kilograms.

Device

Initially, DT-75 was produced with a four-cylinder four-stroke diesel engine SMD-14 (75 "horses") having liquid system cooling. In later modifications, Motors A-41 (90 hp) and SMD-18H (95 hp) were applied. Starting the unit was carried out through an electric starter, feed from the battery, from a driver's seat. Heated engine provided preheater PZHB-200.

The mechanisms and tractor nodes are mounted on a welded frame made up of two longitudinal spars having a closed rectangular section and connected by transverse bonds.

Due to the dry, two-disc, constantly closed clutch clutch with a torque magnifier, a quarter of a quarter of a quarter is achieved when additional resistance occurs. Rear axle and gearbox Dt-75 are mounted in one case, tractor brakes - tape. The chassis is represented by leading and guide wheels supporting rollers, two caterpillar chains and four balancing carriages of the suspension. The hydraulic system provides the driver with the ability to control trailers, mounted and semi-mounted cars from the cab.

Cabin in Dt-75 is all-metal, tight and sealed. It belongs to the closed type and is designed for two people. Seats can be adjusted for driver parameters. By means of a ventilation unit that feeds moistened, cooled and purified air, normal temperature conditions are created in the cabin. In winter, it is possible to install the heater of the canorospheric type. The design of the cabin allows you to work on DT-75 in different conditions. Improvement of visibility is achieved by offsetting the cabin from the tractor axis to the right.

Now the model, despite the preservation of the old brand, has a fundamentally different filling. The engine power is increased to 100 "horses", the safety and reliability of the attachment, transmission nodes and sound system, improved efficiency and smoothness. The model is also additionally completed with a reverse gearbox and a leader.

Rear and front wiper, vibration-insulated and sealed cabin with heater and air cooler, extra seat and glass washers guarantee comfortable working conditions.
The popularity of DT-75 is also due to excellent maintainability. Replacing spare parts on this model is quite simple. True, recently, the components for the tractor DT-75 find it becomes more and more difficult, and the new models are somewhat different from previous versions.

Price

The cost of the new tractor Dt-75 depends on the modification and ranges from 0.7 to 1.6 million rubles. However, the supported options are very popular. They can be purchased for 150000-500,000 rubles.

DT 75 tractor video

In terms of output, he even surpassed the notorious "HTZ" and "T-190", although now in agriculture is rare: the agrarians have long used energy-saturated wheeled tractors. But road builders, builders and landorators are not in a hurry to write off the technique, which is no wear. Such a case. About a year ago, DT-75 has fallen from the bridge for about a year ago. And what do you think: from the tractor only the cabin flashed, he, figuratively speaking, smoked and drove further. True, there is a problem with spare parts. No sale, suitable parts are taken in the written off copies, as a result of two tractors, one component. So what else was still loved by "DT-75" and why are they not treated with him to part?

In 1963, "Dt-75" of the third traction class, which replaced the outdated model "Dt-54" was released at the Volgograd Tractor Plant. "Seventy" used for agricultural work on increased speeds With hinged, semi-mounted and trailed equipment. The maximum speed is a little more than 10 km / h forward and more than 4 km / h. Back, productivity is 30 percent higher than that of DT-54.

Since 1978, the tractor has been a new coat cabin, shifted to the right from the axis. And the fuel tank of an increased container designers placed on the left side of the cabin, and this gave reason to call "Dt-75" "Postman".

This name also secured behind the modifications of the original unit: "DT-75B" with the SMD-14NG engine and its swamp option "Dt-75BV". "Dt-75m" and "Dt-75mv" with the engine A-41. "DT-75N" with the engine of the SMD-18H and its marsh variant "Dt-75NB" and others. In the 70s, the collective farms did more and more orders for these tractors, and the capacity of the Volgograd plant was missing. From 1969 to 1992, DT-75 began to produce a Pavlodar tractor plant in Kazakhstan. Moreover, Pavlodar tractor signed "Kazakhstan", Volgograd - "Dt-75".

Small lyrical retreat. In the Sabakaevsk eight-year school of the Ulyanovsk region in the 1966-67 school year, the guys were collected by scrap metal. He wanted to send it to the plant so that the tractor was made there.

Iron handed over October, pioneers. Those who lovers were looking for scrap, and those who older were collected and sent to the reception center. Transferred on horseback, trolleys, even manually brought. Schoolchildren burned the idea. But doubted whether the metal is enough. And now the exciting moment has come.

Fizruk School Vasily Gloost, built students in the school yard, where DT-75 stood. New, bright orange. On the door inscription: "Native collective farm from Pioneers of the Sabakaev school."

The rally opened the director of the Tatiana Becktnova School. Chairman of the Borisov Publish Council was made by Natalia Borisov. She handed the keys to the chairman of the collective farm named after Lenin Nikolay Korovkin. The head thanked the pioneers, passed the keys to the best tractorist. He started the equipment and went from the school yard to the agricultural enterprise.

Old models "DT-75" - are now rare, you can say rarity. One was found in the Tolochinsky PMS. Cabin with one swing door. Salon - Paradise for lovers to pull something. Many levers - but all of them are needed. At the honorable place - levers of the planetary mechanism of rotation. The driver manipulates - they and the tractor unfolds.

The tractor has more than ten modifications - the so-called younger brothers. One of them "Dt-75s". Start of release - 1983. Range of operating speeds - from 9 to 19 km / h. Gearbox - automatic. Engine power - 170 "horses".

Komsomol members of the plant, young inventors and rationalizers were engaged in the creation of "DT-75C". They half designed prototypes.

A focus on the working conditions of the driver. The cab is sealed and well isolated from noise. When the engine is running, you can talk without increasing the voices. Good review And ventilation - additional amenities. In the heat, the air conditioner cools and moisturizes the air in the cockpit, - recalls the chief designer of the plant Vladimir Shevchuk at that time.

Raisin design - hydrotransmission. The tractorist is easier to drive the machine, you do not need to switch frequently on plowing or harrowing. The torque converter adjusts the speed automatically, the result of the engine life increases. DT-75C has only two main programs, speed up to 22 km / h. Some modifications have a leader with two additional technological transmissions. They are indispensable at the minimum, as the fields are called, "creeping" speeds when irrigating crops.

At that time, the factory workers also worked on promising models of tracked Tractors "W-200" with a power engine of 200 horsepower. It increased performance by 25-30 percent compared to DT-75C. In his cabin - maximum amenities. Control levers are equipped with air coercilers. Designers and safety constructors took care. Cabin at the request of customers equipped with a frame. He protected from deformation when tipping over.

Release on the main conveyor "DT-75" Volgograd Tractor Plant stopped in 2009. There were more than 2741,000 pieces here. In the Soviet Union, the tractor became the most massive among the tracked. Now "DT-75" collects the Volgograd Tractor Company. Here you specify that only VTK produces the legendary DT-75.

Last modernization is the deepest. The name of the new model "Agromash 90tg". The tractor became more versatile. Works such as the installation of a plastic hood, the development of a new modern cabin, expansion of a series of engines, improving the chassis. The list of hits was replenished with a snowplow, a pipe-layer. The tractor is sold with waterfront installation. It is used on pumping of soil, wax and rainwater from catlots, trenches, wells.

In the unit with "DT-75" welding machine. Fastened to the rear hydraulic system. Installation generates electricity for two welding posts with a voltage of 30 volts with a constant nominal welding current of 250 amps each. In addition, an alternator with a power of 4 kW powered lighting and power tools.

The loader on the basis of "Dt-75" is called frontal-cake PFP-1.2. It is not so mass, but itself is unique. The bucket moves the cargo on top of the tractor cab - rear ahead and vice versa. At the same time, PFP-1,2 remains in place.

The MZC-75 model on DT-75 can cut the slit in the frozen ground during the digging of the kittlers, the installation of power grids, laying pipelines and water supply, sewage. The plant produces a bulldozer based on DT-75 with direct, swivel and universal dump with hydroperosecos.

In the reliability of "DT-75" there is no doubt. Itself will pass and the other technique will lead. Only the lastness of the latter is also important. In May 2012, near the Kratuchinsky farm Volgograd region stuck tourist bus. He was pulling "DT". The busement has a trailer device with a headlamp.

Master class on "Dt-75" Gives a Machinist of the Bulldozer of the Tolochinsky PMS Gennady Pushkin (in the picture). For levers of the thirty-year tractor, he is ten years old.

Pulled the lever planetary mechanism It is released, and gear begins freely. The caterpillar turns off, but continues to rotate. Rotate tractor smooth.
