8. Refer to Figure 39. To adjust the inner lift rod, loosen the jam nut on the front ball joint then remove the 1/2” hardware fastening the ball joint the the lift pivot arm. Turn the ball joint clockwise to shorten the distance between the rod pivots or counterclockwise to lengthen the distance between the rod pivots. Reinstall the ball joint on the lift pivot arm and secure with the 1/2” hardware previously removed. Tighten the jam nut against the lift rod. 9. Refer to Figure 39.

Remove the the cutting height adjustment pin from in front of the deck lift pedal arm. Lift mower deck and reinstall adjustment pin in desired mowing height. 42 Measure 1stMeasure 2ndInner Rod Outer Rod Figure 37. Measure the Inner & Outer Lift Rods Figure 38.

Adjust the Inner & Outer Lift Rods Adjust Here Troubleshooting, Adjustment & Service DECK LEVELING ADJUSTMENT NOTE:Before adjusting the deck level, the deck lift rod timing must be checked and/or adjusted. 1. Park machine on a flat, level surface. Disengage the PTO, stop the engine and engage the parking brake. Rear tires must be inflated to 15 psi (1,03 bar); front tires to 25 psi (1,72 bar). 2. Lock the deck lift pedal in the 5” (12,7cm) position. Place the deck height adjustment pin in the 4" position and lower deck the lift pedal until the arm contacts the pin. 3. Place 2 x 4 blocks under each corner of the mower deck with the 3-1/2” sides being vertical. Place a 1/4” (0,64cm) thick spacer on top of the rear 2 x 4 blocks. See Figure 40. 4. Adjust the front eyebolts until the chains are tight and the deck is still resting on the 2 x 4’s. Tighten jam nuts. See Figure 41. 5. Loosen the nuts and allow the rear of the deck to rest on the 2 x 4’s and 1/4” spacers. Slide the chains down in the slots until the chains are tight and tighten the nuts. See Figure 41. 6. Remove all 2 x 4 blocks and spacers from under the mower deck. DECK LIFT SPRING The deck lift springs (A, Figure 42) are factory set to provide optimal lifting performance. Although it is fastened with a multi-position anchor, this is NOT AN ADJUSTMENT POINT. DO NOT attempt to adjust the spring length or lifting performance will be compromised.

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 PTO drive belt (see MOWER BELT REPLACEMENT for removal instructions). 3. Remove the hardware that secures the clutch anchor pad to the PTO clutch. 4. Loosen the nut towards the front of the machine on the spring anchor hook (G, Figure 43) to release the majority of the belt tension. Use caution and remove the nut to completely release the tension. 5. Remove the old belt and replace it with a new one. Make sure the V-side of the belt runs in the grooves of the crankshaft pulley and pump pulleys (B & C). 6. Reinstall the anchor hook (G) into the anchor tab and loosely fasten the nut. Adjust the anchor hook until a measurement of 8-3/8” (21,2 cm) is achieved from the outside if the spring hooks. Tighten nut. 7. Reinstall the clutch anchor pad to the PTO clutch and secure with the hardware previously removed. 8. Reinstall the PTO drive belt. B D A C C F G E Figure 43. Hydraulic Pump Drive Belt Replacement A.

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. Using a 1/2” breaker bar, place the square end in the square hole located in the end of the idler arm (A, Figures 44). Carefully rotate the breaker bar counter-clockwise, which will relieve the tension on the belt exerted from the idler arm. 3. Slide the drive belt over the edge of the stationary idler pulley (B). Carefully release the tension on the breaker bar until the idler arm stops against the center spindle pulley. WARNING Use extreme cautio...
