Deck Installation
To install the mower deck, proceed as follows:
While holding the deck front hanger rod upward,
1.
carefully slide the deck underneath the right side of
the tractor.
While still holding the front hanger rod, slide the deck
2.
forward until the front hanger rod can be lowered into
the slots of the front deck bracket.
Lower the front hanger rod into the slots of the front
3.
deck bracket, then slide the deck rearward.
Maneuver the deck so that the slots in the two rear
4.
deck hanger brackets approximately align with the
deck lift arms of the tractor. Refer to Figure 7-5.
Use the tractor deck lift handle to lower the deck lift
5.
arms into the slots of the rear deck hanger brackets.
Pull the deck support pins outward and maneuver the
6.
deck as necessary to align the holes in the deck lift
arms with the pins. Refer to Figure 7-5.
When aligned, push each pin fully inward through the
7.
lift arms to secure the arms in the rear hanger bracket
slots.
Make certain the ‘V’ belt is in the spindle pulleys on
8.
the deck; then route the belt rearward beneath the
tractor frame, above the transmission tube(s), to the
PTO pulley on the bottom of the engine.
Install the ‘V’ belt onto the PTO pulley using one of
9.
the following two methods.
8"3/*/(
The muffler at the rear of the
tractor may be extremely hot, and could cause
serious burns. Use extreme caution when near
the muffler. Allow the muffler to fully cool
before installing the belt.
Using the Idler Pulley to Tension the Belt.
Using the deck lift handle, raise the deck to the
1.
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.
Install the belt in the PTO pulley on the bottom of the
2.
engine.
Route the backside of the belt around the fixed idler
3.
pulley of the deck. Refer to Figure 7-3.
Working from the middle of the tractor, pivot the idler
4.
bracket/movable pulley rearward against the spring
tension and slide the backside of the belt onto the
movable idler pulley. Refer to Figure 7-3.
Rolling the Belt onto the PTO Pulley.
Using the deck lift handle, raise the deck to the
1.
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.
Make certain the belt is in the spindle pulleys of the
2.
deck, and that the backside of the belt is against both
the fixed and movable idler pulleys. Refer to Figure 7-3.
Sitting behind the tractor, facing forward, make certain
3.
the belt is not twisted; then reach beneath the tractor
to grasp the belt and pull it toward the PTO pulley.
8"3/*/(
Use caution to avoid pinching your
fingers when rolling the belt onto the PTO
pulley.
Pull the right side of the belt rearward and place the
4.
narrow V side of the belt into the PTO pulley. See
Figure 7-4.
While holding the belt and pulley together, rotate the
5.
pulley to the left (See Figure 7-4). Continue holding
and rotating the pulley and belt until the belt is fully
rolled into the PTO pulley.
Replacing the Deck Drive Belt
Remove the deck from beneath the tractor, (refer to
1.
Deck Removal).
Remove the hex tapping screws securing the belt
2.
covers to the deck and remove the belt from the
spindle pulleys. Refer to Figure 7-6.
Install the new belt around the spindle pulleys as
3.
shown in Figure 7-6 and reinstall the belt covers.
Route the belt rearward between the two idler pulleys
4.
and reinstall the deck following the instructions in
Deck Installation on page 30.
Mower Blade Care
8"3/*/(
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
