b. Working from the middle of the tractor, pivot the idler bracket and movable idler pulley rearward away from the backside of the 'V" belt (a) just far enough to lift the belt up and over the idler pulley (b). See Figure 4-12. b a Figure 4-12 c. From beneath the rear of the tractor, slide the belt off of the PTO pulley on the bottom of the engine. d. Lower the deck into the deck removal/ installation position using the deck lift handle. See Figure 4-11. e. Skip ahead to step 6. 5. Rolling the belt off the PTO pulley: a. 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. b. Sitting behind the tractor facing forward, reach beneath the tractor to grasp the belt at the front of the PTO pulley. WARNING Use caution to avoid pinching your fingers when rolling the belt off the PTO pulley. c. Pull the left side of the belt rearward and downward while manually turning the PTO pulley to the right until the belt rides out onto the edge of the lower sheave of the pulley. Note: If pulling the right side of the belt, turn the pulley left. d. While still holding the PTO belt (a) downward, continue turning the PTO pulley (b) until the PTO belt (a) is rolled off the PTO pulley (b). Refer to Figure 4-13. (a) (b) (a) Figure 4-13 e. Lower the deck into the deck removal/ installation position using the deck lift handle. See Figure 4-11. f. Move on to step 6. 6. Locate the LH and RH deck release pins (a) on each side of the deck. Pull the deck release pins (a) outward and release the deck from the LH and RH deck lift arms (b). See Figure 4-14. (b) (a) Figure 4-14 CAUTION There is a certain amount of spring tension due to the weight of the deck. When removing the lift linkage from the deck the tension of the springs will go from the deck to the deck lift handle and snap back. 7. Slide the front deck lift rod off the hanger brackets on the front of the deck 8. Place the deck lift handle into the highest mowing position and slide the deck out from the right side of the tractor. Deck Installation Install the deck on the tractor as follows: 1. Place the deck lift handle in the highest mowing position See Figure 4-11. 2. Slide the deck under the tractor on the right side of the tractor lining up the deck hanger brackets and the deck lift arms. 3. Once the deck is under the tractor, move the deck lift handle to the lowest mowing position. Note: To line the brackets up properly, it may be necessary to place a small block of wood under each side of the deck. 4. Hook the front deck lift rod onto the hanger brackets on the front of the deck. 5. Pull the deck release pins outward and maneuver the deck as necessary to align the holes in the deck lift arms with the pins. Refer to Figure 4-14. 6. When aligned, push each deck release pin fully inward through the deck lift arms to secure the deck lift arms in the rear hanger bracket slots. 7. 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. 8. 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. 9. 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. 10. 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. 11. 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 4-13. 12. While holding the PTO belt and PTO pulley together, rotate the PTO pulley to the left (See Figure 4-13). 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. Replacing the Belt 1. Remove the deck from beneath the tractor, (refer to Deck Removal). 2. Remove the hex washer screws (a) securing the belt covers (b) to the deck. See Figure 4-15.
