Loosen the jam nut that locks against the clevis (B, Figure 29) and turn the linkage rod (A, Figure 29) to adjust. If the machine creeps forward, turn the rod CLOCKWISE (while standing at the rear of the machine, facing forward), if the machine creeps backward, turn the rod COUNTERCLOCKWISE. 3. Lock the jam nut (B, Figure 29) against the clevis when neutral is achieved. NOTE: This adjustment shouldnotbe performed while the machine is running.It may take several attempts to achieve neutral, depending upon how much the machine creeps. CUTTING HEIGHT ADJUSTMENT The cutting height adjustment pin (A, Figure 30) controls the mower cutting height. The cutting height is adjustable between 1-1/2” (3.8cm) and 4-1/2” (11.4cm) in 1/4” (.64cm) increments. Depress the deck lift foot pedal (B, Figure 30), placing the majority of the force on the top edge of the pedal until it locks into the “TRANSPORT” position. Place the cutting height adjustment pin in the desired cutting height. Depress the deck lift foot pedal, placing the majority of the force on the bottom edge of the pedal to release the pedal from the “TRANSPORT” position. A B Figure 29.

Disengage the PTO, stop the engine and engage the parking brake. Rear tires must be inflated to 15 psi (103 kPa); front tires to 25 psi (172 kPa). 2. Place the deck height adjustment pin in the 4" position. 3. Place 2 x 4 blocks under each front corner of the mower deck with the 3-1/2” sides being vertical. 4. Place 2 x 4 blocks under each of the rear edge of the mower deck near the chains with the 3-1/2” sides being vertical. Place a 1/4” spacer on top of the rear 2 x 4’s. 5. See Figure 31. Measure the distance between the lift pivots and the spring rod pivots. Adjust the 5/8” hex nuts on either side of the front spring rod pivot until the measurements are equal. 6. See Figure 32. Measure the distance between the rear lift pivots and the suspension-mounted lift pivots. Add or remove 5/8” SAE washers from in between the deck lift rod and the offset link until measurements are equal. 7. Adjust the front U-bolts until the chains are tight and the deck is still resting on the 2 x 4’s. Tighten jam nuts. See Figure 33. 8. 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 33. 9. Remove all 2 x 4 blocks from under the mower deck. 10. With the deck height adjustments complete and cutting height still set at 4", adjust the deck lift spring to a compressed length of 12-1/4" (measure 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 33). After adjustment is made, tighten these two nuts together. Perform this step to both springs.

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. Loosen the nut towards the front of the machine on the spring anchor hook (H, Figure 34) to release the majority of the belt tension. Use caution and remove the nut to completely release the tension. 4. Remove the old belt and replace it with the new one. Make sure the V-side of the belt runs in the grooves of the crankshaft pulley and pump pulleys (B & C, Figure 34). 5. Reinstall the anchor hook (H, Figure 34) into the anchor tab and loosely fasten the nut. Adjust the spring until a measurement of 7-3/4” is achieved from the outside if the spring hooks. Tighten nut. 6. Reinstall the PTO drive belt. MOWER BELT REPLACEMENT To avoid damaging belts, DO NOT PRY BELTS OVER PULLEYS. 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. Remove the floor plate to gain access to the PTO drive belt. 3. Loosen the spring compression nut (B, Figure 35) to release the belt tension. 4. Slide the drive belt over the edge of the idler pulley and then slide the belt under the idler pulley. Drop the belt from the PTO clutch pulley groove. 5. Remove the old belt and replace with a new one. Make sure the V-side o...
