Abstract
A rear mechanism for a work machine includes first and second spring housings operably engaged by one or more springs. The first and second spring housings are assembled with an endcap housing between first and second clutch packs that engage a rear axle of the work machine. A first cavity is formed between the first and second spring housing, and a second cavity is formed between the first housing and the endcap housing. Pressurizing the first cavity compresses the springs and releases a park brake of the work machine to enable front wheel drive of the work machine. While pressurizing the first cavity, the second cavity is pressurized such that the first spring housing compresses the first clutch pack to enable four wheel drive of the work machine.
