•Slide the deck forward so that the deck front hanger rod can be lifted out of the two slots of the front deck bracket. After lifting the front hanger rod out of the slots, slide the deck rearward so that the rod can no longer engage the slots.

•Using care to prevent the front hanger rod from falling back into the deck slots, gently 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 28.

5.Use the deck lift handle of the tractor 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 28.

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.

Using the idler pulley to tension the belt.

•Using the deck lift handle, raise the deck to the upper position that allows for the most horizontal run of the belt between the deck idler pulleys and the PTO pulley on the bottom of the engine.

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, or allow the muffler to fully cool before removing the belt.

•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 27.

•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 27.

Rolling the belt into the PTO pulley.

•Using the deck lift handle, raise the deck to the upper position that allows for 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 27.

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, or allow the muffler to fully cool before removing the belt.

•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 off the PTO pulley.

•Pull the right side of the belt rearward and place the narrow V side of the belt into the right/front side of the PTO pulley. See Figure 29.

•While holding the belt and pulley together, rotate the pulley to the left (See Figure 29). Continue holding and rotating the pulley and belt until the belt is fully rolled into the PTO pulley. NOTE: If using the left side of the belt, turn the pulley to the right.
