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.

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.
