To properly sharpen the cutting blades, remove equal amounts
of metal from both ends of the blades along the cutting edges,
parallel to the trailing edge, at a 25° to 30° angle.
IMPORTANT: If the cutting edge of the blade has already been
sharpened to within 1 ⁄” from the edge, or if any metal separation
is present, replace the blades with new ones. See Fig. 7-5.
CAUTION: If the cutting edge of the blade has previously been
sharpened, or if any metal separation is present, replace the
blades with new ones.
WARNING! A poorly balanced blade will cause
excessive vibration, may damage to the tractor and/
or result in personal injury.
Test the blade’s balance using a blade balancer. Grind
metal from the heavy side until it balances evenly.

NOTE: When replacing the blade, be sure to install the blade with
the side of the blade marked ‘‘Bottom’’ (or with a part number
stamped in it) facing the ground when the mower is in the
operating position.
CAUTION: Use a torque wrench to tighten the
blade spindle hex flange nut to between 70 lbs-ft
and 90 lbs-ft.
Changing the Deck Belt
WARNING! Be sure to shut the engine off, remove
ignition key, disconnect the spark plug wire(s) and
ground against the engine to prevent unintended
starting before removing the belt.
WARNING! All belt on your tractor are subject to
wear and should be replaced if any signs of wear are
present.
IMPORTANT: The V-belt found on your tractor are specially
designed to engage and disengage safely. A substitute (non-
OEM) V-belt can be dangerous by not disengaging completely.
For a proper working machine, use factory approved belts.
To change or replace the deck belt on your tractor, proceed as follows:
Lower the deck by moving the deck lift lever into the
bottom notch on the right fender.
Remove the belt guards by removing the self-tapping
screws that fasten them to the deck.
Remove the belt keeper rod from around the engine pulley.
Loosen but do not remove, the idler pulley nuts. This will
enable the belt to be easily removed from the idler pulleys.
See Fig. 7-6.
WARNING! Avoid the possibility of a pinching
injury. Do not place your fingers on the idler spring
or between the belt and a pulley while removing the
belt.
