A tracked vehicle has smooth driving and idler wheels (6, 7, 8, 9), which frictionally transmit the tractive force to tracks (3, 4), e.g. rubber tracks, and which are mounted on a frame (3) of the vehicle which carries at least one driving engine (11). To avoid the slipping of the tracks on the driving and idler wheels, both the two front idler wheels (6, 7) and the two rear idler wheels (8, 9) are respectively driven. The front wheels are hydraulically driven, while the rear wheels may be hydraulically or mechanically driven.
