See Figure 47. 8. Remove all 2 x 4 blocks and spacers from under the mower deck. 9. With the deck height adjustments complete and cutting height still set at 4", adjust the deck lift spring to a compressed length of 12" (30,5cm). Be sure to measure the spring only. Adjust the length of the deck lift spring by tightening or loosening the (2) 5/8” hex nuts that are closest to the spacer at the front end of the spring (see Figure 47). After adjustment is made, tighten these two nuts together. Perform this step to both springs. Troubleshooting, Adjustment & Service BELT REMOVAL & REPLACEMENT To avoid damaging belts, DO NOT PRY BELTS OVER PULLEYS. Mower Drive Belt Removal & Replacement 1. Park the tractor on a smooth, level surface such as a concrete floor. Disengage the PTO, engage the parking brake, turn off the engine, and remove the ignition key. 2. See Figure 48. Remove the hairpin clip and clevis pin and remove the deck lift foot pedal. Lift the floor plate to gain access to the PTO drive belt. 3. Remove the mower deck guards. 4. Loosen the spring compression nut (B, Figure 49) to release the belt tension. 5. Slide the drive belt over the edge of the spring- loaded idler pulley and remove belt from all pulley grooves. 6. Remove the old belt and replace with a new one. Make sure the V-side of the belt runs in the pulley grooves (Figure 50). 7. Install the drive belt on the gearbox pulley, the spindle pulleys and idler pulleys. Tighten the spring compression nut (B, Figure 49) until the belt tension spring (A, Figure 49) is compressed to 1-5/8” (4,12cm) long. 8. Lower the floor pan and reinstall the deck lift foot pedal, clevis pin and hairpin clip. Make sure the deck lift lock bar is located as shown in Figure 48. 9. Reinstall the mower deck guards and secure with the 5/16” hardware previously removed. 10. Run the mower under no-load condition for approximately 5 minutes to break in the belt. Figure 50.

Park the tractor on a smooth, level surface such as a concrete floor. Disengage the PTO, engage the parking brake, turn off the engine, and remove the ignition key. 2. Remove the rear skid plate by removing the bolts that fasten the skid plate to the bumper and slide the plate forward until it drops from the mounts. 3. Remove the rear belt shield and rear hood support. 4. Remove the bumper. 5. Remove the nylon lock nut (A, Figure 51) to release the belt tension and unhook the clutch belt idler spring (C) from the screw hook (B). Set the screw hook aside. 6. Remove the 5/16” bolt, washer and nut (D) that fasten the rubber pad to the clutch and unscrew the wire ends that connect the clutch to the electrical harness. 7. Pulling the belts over the bottom edge of the gearbox drive pulley (E), remove the clutch belts from the clutch pulley grooves and pull around the idler pulley. Clutch Belt Replacement & Adjustment 1. Install the clutch belts over the top of the clutch, into the grooves of the crankshaft pulley and around the idler pulley. 2. Push the belts over the edge of the gearbox drive pulley and into the grooves of the pulley. 3. Hook the clutch belt idler spring on the screw hook and reinstall the screw hook into the anchor. Adjust the screw hook until the spring measures 4-3/4” (12,1cm) to the outside of the loops on the spring (see Figure 52). 4. Reinstall the clutch anchor pad to the clutch with the hardware (D) previously removed. Make sure the hardware is in the same order as is was before being removed. 5. Reinstall the bumper, rear hood support, rear belt shield and skid plate. Figure 51. Clutch Belt Removal & Replacement A. 3/8” Nylon Lock Nut B. Screw Hook C. Clutch Belt Idler Spring D.

Park the tractor on a smooth, level surface such as a concrete floor. Disengage the PTO, engage the parking brake, turn off the engine, and remove the ignition key. 2. Remove the clutch belts (see CLUTCHBELT REMOVALfor instructions). 3. Using a 1/2” breaker bar, place the square end in the square hole located in the middle of the idler arm (A, Figures 53). Carefully rotate the breaker bar counter-clockwise, which will relieve the tension on the belts exerted from the idler arm. WARNING Use extreme caution when rotating the idler arm with the breaker bar, due to the increased tension in the spring as the idler arm is being rotated. Injury may result if the breaker bar is prematurely released while the spring is under tension. A Figure 53. Pump Belt Removal & Replacement A. Pump Drive ...
