The GHM (Figure 1-1) is intended for cutting hay and grass in a clean maintained area. A breakaway mechanism built into the three point hitch allows cut- ter bar to pivot back if a stationary object is hit. The cutter bar consists of individual spindle assemblies driven from the main gearbox by a gear train. An optional overrunning clutch is available to allow “coast down” of blades when PTO is disengaged.
