1-2 DESCRIPTION
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.
