摘要：
A work vehicle, such as a motor grader, comprises a frame, a ripper, a tie bar attached to the frame, and a four-bar linkage attached to and disposed between the ripper and the tie bar for transferring a load between the ripper and the frame via the four-bar linkage and the tie bar. The four-bar linkage and the tie bar are co-planar with respect to a plane within which the four-bar linkage is movable relative to the frame. A toolbar for the ripper is also disclosed.
