8. Using care to prevent the front hanger rod from
falling back into the deck bracket slots, carefully
slide the cutting deck (from the right side) out
from underneath the tractor.
DECK INSTALLATION
To install the mower deck, proceed as follows:
1. While holding up the deck front hanger rod,
carefully slide the deck underneath the right side
of the tractor.
2. While still holding the front hanger rod, slide the
deck forward until the front hanger rod can be
lowered into the slots at the front of the deck.
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 30.
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 arm with the pins. Refer to Figure 30.
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 and above the two transmission
tubes
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
belt.
Using the idler pulley to tension the belt.
• 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 29.
• 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 29.
Rolling the belt into the PTO pulley.
• 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 29.
• 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 prevent
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 pul-
ley. See Figure 31.
• While holding the belt and pulley together, rotate
the pulley to the left (See Figure 31). Continue
holding and rotating the pulley and belt until the
belt is fully rolled into the PTO pulley.
