7.6 Rotor Blades – Checking
Observe rotor blade performance daily. Check sharpness
every 50 hours.
The rotor is equipped with two opposing blades. The rotor
blades shear material off as they rotate past the stationary
ledger knife. Keep the blades sharp for optimum performance.
Sharp blades reduce the amount of power required during
operation. Periodic inspection is recommended.
NOTE:
Check the sharpness of the knives more
frequently if processing material with a lot of
sand, soil or grit in it. Reverse or sharpen the
knives if performance diminishes. If sharpening
or replacing a blade, do the opposing one as
well.

Remove the blades from the rotor to sharpen them. Always
sharpen the blade edge at a 45° angle to provide the best cutting
effect as the rotor turns.

Procedure
1.
Open the rotor housing to manually rotate the rotor plate so
one of the blades is accessible.
NOTE:
Rotating the rotor requires lifting the clutch lever
off the brake position slightly. Brake should be
re-engaged to lock rotor before attempting to
loosen bolts.
2.
Release the clutch lever so the brake engages to lock the
rotor. Remove the bolts and the blade.
3.
Lift the clutch lever off the brake position slightly to rotate
the rotor and remove the other rotor handle.
4.
If sharpening the blades, sharpen both evenly. Sharpen
or rotate each in the same manner. If a blade needs to be
replaced, replace both blades.
IMPORTANT! Treat both blades equally to keep the rotor
balanced as it turns.
5.
Install the blades with the leading edge out. Apply blue
Loctite® to the bolt threads and torque-tighten bolts to
33 lbf•ft (45 N•m)
