Tractor Blade Care
WARNING
Before performing any maintenance, place the PTO switch in
the "OFF" position, engage the parking brake lever, turn the
ignition key to the "OFF" position and remove the key from
the switch. Protect your hands by using heavy gloves when
handling the blades. When servicing the tractor deck, be
careful not to cut yourself on the sharpened blades.
The cutting blades must be kept sharp at all times.
Sharpen the cutting edges of the blades evenly
so that the blades remain balanced and the same
angle of sharpness is maintained.
If the cutting edge of a blade has already been
sharpened many times, or if any metal separation
is present, it is recommended that new blades
be installed. New blades are available at your
authorized dealer.
The blades may be removed as follows.
1. Remove the deck from beneath the tractor,
(refer to Deck Removal) then gently flip the
deck over to expose its underside.
2. Use a 15⁄16" wrench to hold the hex nut on top
of the spindle assembly when loosening the
hex nut (a) securing the blade (b). A block of
wood (c) may be placed between the deck
housing and the cutting edge of the blade
(b) to help in breaking loose the hex nut (a)
securing the blade. See Figure 4-16.

3. When reinstalling the blades, be sure they are
installed so that the wings are pointing upward
toward the top of the deck.
4. Tighten the hex nuts (a) to 70-90 ft. lbs.
5. Reinstall the deck (refer to Deck Installation).
Changing the Transmission Drive Belt
Several components must be removed and
special tools used in order to change the tractor's
transmission drive belt. See your authorized
service dealer to have the transmission drive belt
replaced.
Tractor Creeping
Creeping is the slight forward or backward
movement of the tractor when the throttle is on
and the speed control levers are in the neutral
position. If your tractor creeps, see an authorized
service dealer.
