Abstract

60 years ago, on December 30, 1963, serial production of the most famous and widespread tracked agricultural tractor, DT-75, was started at the Volgograd Tractor Plant. During the production period, the plant gradually moved from manufacturing of a single model, the above-mentioned DT-75 general-purpose tractor, to manufacturing of a large line-up of modifications and specifications, the total number of which is approaching 30. This number includes mass-produced basic general-purpose tractors DT-75, DT-75M, DT-75MV, DT-75N, DT-75D, their swamp modifications DT-75B, DT-75BV, DT-75NB and the steep modification DT-75K. There are also the peat tractor DT-75DT and the arable-tilled tractors DT-75NP, DT-75DP, produced in small batches. In addition, there are the tractors DT-75DA, DT-75BK, DT-75BR, remaining only in prototypes. These little-known tractors are covered in this paper.
