Maintenance Instructions CHECKING/SERVICING
Blade Brake Action
Check the function of the cutter blade brake by en-
gaging the blade clutch (PTO), operating the engine
at full throttle, then disengaging the clutch and mea-
suring how quickly the blades stop. Watch the rota-
tion of the blade drive shaft as a visual indication that
movement has stopped. If the brake is working
properly, all rotation will stop five (5) seconds af-
ter disengagement of the clutch. If the brake sys-
tem malfunctions - blades do not stop in five (5)
seconds - adjust or repair the brake before operating
the mower. Refer to ADJUSTMENTS of Blade
Clutch (PTO) in this section.
