Abstract

A work vehicle (10) such as, for example, a tractor (74) or loader (27) has a center of gravity (12), a body (14) and first and second continuous track assemblies (18, 20). In the use of the tractor (74), for example, forwardly locating the center of gravity (12) can increase penetration of a bulldozer (76) on the tractor (74) during bulldozing operations. During ripping operations, penetration of a ripper (78) on the tractor (74) can be increased by rearwardly locating the center of gravity (12). Apparatus (22) is provided for controllably moving the body (14) relative to both of the track assemblies (18, 20). Said apparatus (22) thus controllably shifts the center of gravity (12) of the tractor (74) relative to both of said track assemblies (18, 20) for selectively increasing penetration of the ripper (78) or bulldozer (76) depending upon the operation being performed by said tractor (74).
