The evolution of design of general purpose tracked tractors

BACKGROUND: The most important task, that supported the formation of mechanized agriculture in 192030s, was creation domestic tractor industry. Stalingrad (Volgograd) Tractor Plant, being flagship this industry for many years, played a fundamental role its development.
 AIMS: Justification relevance within process country industrialization. Analysis advantages tracked tractors comparison with wheeled tractors, justification need their mass production, determination trends development technical and operational characteristics general purpose tractors.
 METHODS: evolution parameters design produced by Plant throughout operation analysis specification ten highest performance different years enterprise.
 RESULTS: It is found first models were based on met requirements soil climate conditions our best way, as well satisfied use such machines military purposes. importance using energy saturation indicator main factor at increased velocities justified; graph behavior indicator, depending production year, given further growth are noted.
 CONCLUSIONS: plant 55 has 1.85 times, from 7.5 to 13.91 kW. experience Volgograd manufacturers should be analyzed used order identify patterns, modern directions technology development.
