Blade Brake Action
Check the function of the cutter blade brake (and
blower brake on GHS models) by engaging the blade
clutch (PTO), operating the engine at full throttle,
then disengaging the clutch and measuring how
quickly the blades stop. Watch the rotation of the
blade drive shaft and blower pulley as a visual indi-
cation that movement has stopped. If the brake is
working properly, all rotation will stop five (5)
seconds after disengagement of the clutch. If the
brake system 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.
REPLACING/REPAIRING
IMPORTANT: ALWAYS use genuine factory re-
placement parts. Substitute parts CAN result in
product malfunction and possible injury to the oper-
ator and/or others.
