Abstract

A continuous track assembly (12) has a frame (16) and a first element (18) pivotally connected to the frame (16). A second element (20) is pivotally connected to the first element (18). Each element (18, 20) has a rotatable wheel (22, 24) about both of which a track (30) is positioned. The wheel (22) of the first element (18) is rotated by power and driving apparatus (36, 44) in an associated work vehicle (10) to drive the track (30). Tension in the track (30) is maintained at a preselected level by apparatus (50) which moves the second element (20) relative to the first element (18) to position the wheels (22, 24) against the track (30). The wheels (22, 24) are freely pivotally movable as a unit to enable the track assembly (12) to readily adapt to its environment and maximize tractive effort. Maintaining the desired track tension substantially overcomes problems associated with a track which is too loose or tight which can result in slipping or damage to the track assembly (12).
