IMPORTANT: When sharpening blades, be
sure to grind the same amount on each side.
Unbalanced blades will cause excessive
vibration and could cause the spindles to
wear prematurely.
Check the blade balance by inserting a
horizontal rod through the center hole of the
blade. The heavy side of the blade will drop
down. Sharpen the heavy side of the blade
until the blade is balanced, see figure 31.
After sharpening, install the blades back onto
the mower deck. Make sure the wings are
facing up. Reinstall the blade bolt and
lockwasher.
CLEANING GRASS BUILDUP FROM
DECK
Cleaning the underside of the deck regularly
will help maintain deck cutting efficiency.
Clean the underside of the deck as often as
possible.
To gain access to the underside of the deck,
depress the deck lift foot pedal and lock it in
the transport position. Move the deck cut
height adjustment to the highest setting.
Raise the front of the power unit and support
it with jackstands.
Clean out any grass buildup from under the
deck and discharge shield. DO NOT use high
pressure washers or sprayers.
BELTS
Inspect the belt pulley grooves and flanges
for wear. A new belt, or one in good condition,
should not contact the bottom of the pulley
groove. Replace the belt when the belt
touches the bottom of the groove otherwise
the belt will slip excessively.
Always use caution when changing a belt.
Never pry a belt on to a pulley.
Always keep oil and grease away from the
belts and never use belt dressings.
Belts should be checked regularly, and
replaced at approximately 250 hour intervals.
Belts should also be replaced any time the
belt(s) show evidence of cracking, missing
pieces, friction burns from slipping, or other
extreme damage. Small cracks or fabric
polishing are normal.
