SERVICE AND MAINTENANCE, cont'd
3. Re-install the applicable hardware for the tractor, in reverse order of the
removal process:
a. Install the hanger rod clevis ends of the deck height adjust rods removed in Step 8
of Deck Removal and secure with the bow-tie pins previously removed.
b. Reinstall the deck stabilizer rod, at the rear of the deck, onto the frame at
the left side, and onto the deck on the right side, with the bow-tie pins
previously removed.
c. Reinstall the front hanger rods into the front center brackets on the deck and
secure with the bow-tie pins previously removed.
4. Make certain the "V" belt is in the spindle pulleys on the deck.
5. Make certain that the backside of the belt is against both the fixed and movable idler
pulleys. Reinstall or tighten any idler pulley hardware previously removed or loosened
for deck removal.
6. Route the belt rearward beneath the tractor frame, above the rear deck stabilizer bar,
above the transmission tube(s), to the PTO pulley on the bottom of the engine.
7. Raise the deck to the position that provides the most horizontal run of the belt
between the deck idler pulleys and the PTO pulley on the bottom of the engine.
8. Sitting behind the tractor, facing forward, make certain the belt is not twisted; then
reach beneath the tractor to grasp the belt and pull it toward the PTO pulley.
WARNING: Use caution to avoid pinching fingers when rolling the belt onto
the PTO pulley.
9. Pull the right side of the PTO belt rearward
and place the narrow V-side of the PTO belt into
the PTO pulley. See Figure 52.
10. While holding the PTO belt and PTO pulley
together, rotate the PTO pulley to the left (see
Figure 46). Continue holding and rotating the
PTO pulley and PTO belt until the PTO belt is fully
rolled into the PTO pulley.
nOTE: Before using the tractor double-check the
belt routing to make sure that the belt has been
routed properly.
11. Check deck level and pitch. Adjust if necessary.
Replacing the Belt
1. Remove the deck from beneath the
tractor (refer to Deck Removal).
2. Remove the hex thumb screws
securing the belt covers to the deck.
See Figure 53.
3. Remove the belt covers from the deck.
See Figure 54.
4. Remove the two idler pulley
assemblies by removing the flange
lock nuts (a) at the top of the
assemblies, then removing the
assemblies from the idler arm. See Figure 55.
Figure 54
nOTE: Take note of all hardware, including
the positions of the belt keepers for proper
reinstallation later.
5. Remove the belt from the spindle pulleys.
6. Install the new belt around the spindle pulleys
as shown and reinstall the belt covers removed
in Step 3 of this section.
7. Place the belt around the idler pulleys removed in Step 4 with the "V" side facing in,
and no kinks or twists along the run of the belt. Once in place, loosely reinstall the
idler arm hardware.
8. Route the belt as shown in Figure 56. Tighten and secure the idler arm hardware.
Tractor Blade Care
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
Figure 52
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 an 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
Figure 53
hex nut on top of the spindle
assembly when loosening
the hex nut (a) securing the
(a)
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 an 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 tractor creeps, see an
Figure 55
authorized service dealer.
Figure 56
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 hands by using heavy gloves
when handling the blades. When servicing the tractor deck, be careful not to
cut yourself on the sharpened blades.
