SERVICE AND MAINTENANCE
Tractor Blade Care
WARNING
Before performing any maintenance,disengage the PTO and move the
lapbar drive control levers fully outward into the Park Brake engaged
position. If leaving the tractor unattended, turn the ignition key to the
STOP position and remove key.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 ⁄” 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 57.
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. (95-122 N-m).
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
