The history of domestic tractor construction - Crawler tractors

A Set of 4 stamps were released by Russia Post on the crawler tractors on 29th September 2021 depicting F.A. Blinov tractor (1896), S-60 "Stalinets" (1933), DT-54 (1949) and the CHETRA T40 bulldozer (2005).

Tractor is a self-propelled wheeled or tracked vehicle that performs agricultural, road construction, earth moving and other work independently or in an aggregate with trailed, mounted or stationary equipment.

Crawler tractors, unlike wheeled tractors, have a large traction force and high cross-country ability, at a low speed (5-40 km / h), they provide reduced pressure on the ground and, accordingly, better grip with the ground, they easily move off-road or rough ground areas. They are mainly used as tractors on tracks for work in fields, construction sites and logging.
