Abstract: A tilt mechanism for supporting a cab assembly of a work machine is described. The tilt mechanism includes a frame. The tilt mechanism also includes a support member for supporting the cab assembly. The support member is mechanically coupled to the frame so that the support member is movable relative to the frame. The tilt mechanism further includes an actuation mechanism mechanically coupled to the frame and the support member. The actuation mechanism is operable between a retract mode of operation and an extend mode of operation. Placing the actuation mechanism in the extend mode of operation causes the support member to move relative to the frame such that the support member advances a distance D.sub.1 along an axis of the frame in a first direction. Placing the actuation mechanism in the retract mode of operation causes the support member to move relative to the frame such that the support member advances a distance D.sub.2 along the axis of the frame in a second direction.
