2. While still holding the front hanger rod, slide the deck forward
until the front hanger rod can be lowered into the slots of
the front deck bracket.
3. Lower the front hanger rod into the slots of the front deck
bracket, then slide the deck rearward.
4. Maneuver the deck so that the slots in the two rear deck
hanger brackets approximately align with the deck lift arms
of the tractor. Refer to Figure 7-6.
5. Use the tractor deck lift handle to lower the deck lift arms
into the slots of the rear deck hanger brackets.
6. Pull the deck support pins outward and maneuver the deck
as necessary to align the holes in the deck lift arms with the
pins. Refer to Figure 7-6.
7. When aligned, push each pin fully inward through the lift
arms to secure the arms in the rear hanger bracket slots.
8. Make certain the 'V' belt is in the spindle pulleys on 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.
9. Install the 'V' belt onto the PTO pulley using one of the
following two methods.
WARNING!
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

Using the deck lift handle, 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.
Install the belt in the PTO pulley on the bottom of the
engine.
Route the backside of the belt around the fixed idler pulley
of the deck. Refer to Figure 7-4.
Working from the middle of the tractor, pivot the idler
bracket/movable pulley rearward against the spring
tension and slide the backside of the belt onto the movable
idler pulley. Refer to Figure 7-4.
Using the deck lift handle, 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.
Make certain the belt is in the spindle pulleys of the deck,
and that the backside of the belt is against both the fixed
and movable idler pulleys. Refer to Figure 7-4.
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 your
fingers when rolling the belt onto the PTO pulley.
Pull the right side of the belt rearward and place the
narrow V side of the belt into the PTO pulley. See Figure
7-5.
While holding the belt and pulley together, rotate the
pulley to the left (See Figure 7-5). Continue holding and
rotating the pulley and belt until the belt is fully rolled into
the PTO pulley.
