Two tillers were available for the 318, a 48-inch shaft drive and a 30-inch hydraulic tiller (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. Three baggers were available. A two-bag (6.5 bushel) Power Flow system had a fan that was belt-driven from the right-hand mower spindle. A three-bag (10 bushel) system had an auxiliary 6-horsepower Kawasaki engine to run the blower. A 13-bushel material collection system used an auxiliary 6-horsepower Kawasaki engine and was available with manual tilt dump or a hydraulic dump connected to a rear hydraulic outlet; it could dump 370 pounds at a height of 66 inches.
