The DT-75 ( Russian ДТ-75 ) is a Soviet and later Russian chain tractor , which was produced from 1963 to 2015 in the Volgogradski Traktorny Sawod (German Volgograd Tractor Plant , abbreviated ВгТЗ or WgTS). In addition, the Pavlodarski Traktorny Sawod (ПТЗ or PTS for short) also manufactured vehicles of this type. With over 2.7 million units built, it is one of the most frequently built tractors in the Soviet Union and Russia .
Vehicle history
The first prototypes of the DT-75 were built in 1956 in what was then still the Stalingradski Traktorny Sawod imeni FE Dzerzhinskovo tractor factory. The decision to build the vehicle in series fell, 1960. 1961 the work was presented Wolgogradski Traktorny Sawod renamed, since Stalingrad during the de-Stalinization in Volgograd has been renamed.
The information on when series production finally began fluctuated between 1962 and 1963. The DT-75 replaced the previously built DT-54 in Volgograd . From 1966 a revised version was built under the designation DT-75M, which has an engine output of 90 hp (66 kW). In 1968 the newly built Pavlodarski Traktorny Sawod in Pavlodar , Kazakhstan , began manufacturing the tractors. The DT-75M rolled off the production line there until the mid-1980s. The vehicles can be recognized by the word “Kazakhstan” on the hood where 'DT-75' is normally stamped.
In the 1970s, the design of the vehicle was fundamentally revised. The cabin and the hood were replaced by rectangular products. In addition, various versions with small modifications were made up into the 1990s. They were designated as DT-75B, DT-75N, DT-75S, etc. and often differed in terms of attached additional equipment, the motorization or the hydraulic system. The Pavlodar plant also produced other versions from the mid-1980s, for example the DT-75ML with a rectangular cabin. These were not built for this in Volgograd. In 1984 production reached its peak with 55,000 tractors in Pavlodar alone. After the collapse of the Soviet Union , sales collapsed. In 1997 only just under 1900 vehicles from the PTS production were sold.
By 1995 a total of 2,514,800 DT-75 tractors had been built. Of this, 862,300 went to Pavlodar and 1,652,500 to the production of the Volgograd plant. While the plant in Pavlodar never recovered from the economic difficulties after the collapse of the Soviet Union and was finally insolvent in 2005, the revised design of the DT-75 in Volgograd was built until 2015. The tractor was in series production for more than half a century. By 2009, the total number of items produced rose to over 2,714,000.
Both the original version DT-75 with a round cab and the DT-75M with a square cab came to the German Democratic Republic . The latter partially with a special creeper with 16 gear steps in the range up to 4.74 km / h. At the end of 1988 the agricultural production cooperatives in the GDR had 846 machines in stock, with the majority of 541 units being procured between 1981 and 1985.
