Two tillers were available for the 322, a 48-inch shaft drive and a 30-inch hydraulic tiller (with optional extension to 42 inch). The shaft-drive tiller required the optional 2000 RPM rear PTO. The hydraulic tiller operated off a separate hydraulic pump that was belt-driven in place of the mower deck. A rear-mounted finish mower was available for the 318, if equipped with three-point hitch and 2000 RPM rear PTO.Reference
