3. Move the ground speed control levers towards the neutral position. If the levers do not align with the notches in the neutral lock plate, it is necessary to adjust the reverse return bolts (A, Figure 34). Neutral Position Adjustment 1. Loosen the jam nut (D, Figure 34) locked against the clevis. 2. Turn the reverse return bolt (A) clockwise to adjust handle rearward, counter-clockwise to adjust handle forward. 4. Pull lever rearward and release to check position again. Adjust as necessary to align levers with notches. It is important to note that after every adjustment of the reverse return bolt, the lever must be pulled rearward and released to properly check the neutral position. 5. Once the lever alignment has been adjusted, lock jam nut against the clevis. Return Spring Adjustment After adjusting the neutral position, lock the levers in the neutral position and measure the reverse return spring (B, Figure 34) length. This should be 2-3/8” (6,03 cm) long. If not, hold the reverse return bolt (A) Troubleshooting with a wrench while turning the spring position nut (C) until the measurement is achieved.

Jam Nut 42 NEUTRAL ADJUSTMENT If the tractor “creeps” while the ground speed control levers are locked in NEUTRAL, then it may be necessary to adjust the control linkage. NOTE:Perform this adjustment on a hard, level surface such as a concrete floor. The neutral position MUST be checked and adjusted BEFORE performing a neutral adjustment. 1. Disengage the PTO, engage the parking brake and turn off the engine. 2. Loosen the jam nuts (B, Figure 35) and turn the adjustment linkage (A) to adjust. If the machine creeps forward, turn the linkage CLOCKWISE (while standing at the rear of the machine, facing forward), if the machine creeps backward, turn the linkage COUNTER-CLOCKWISE. 3. Lock the jam nuts (B) when neutral is achieved. NOTE: This adjustment should NOT be performed while the machine is running.It may take several attempts to achieve neutral, depending upon how much the machine creeps. B B A Figure 35.

Disengage the PTO, stop the engine, block the front wheels, remove the ignition key, and engage the parking brake. 2. Jack up the rear of the machine and secure with jackstands. Remove both drive tires. 3. With the parking brake engaged, measure the compressed spring length (see Figure 36). The spring should be 2-1/8” - 2-1/4” (5,4 - 5,7 cm) long when compressed. 4. If the spring does not measure 2-1/8” - 2-1/4” (5,4 - 5,7 cm), release the parking brake and turn the adjustment nut (B) to adjust the spring length 5. Engage the parking brake and remeasure the spring length. Continue to adjust the nut as required. CAUTION Do not adjust the spring to be shorter than 2-1/8” (5,4 cm) when compressed. This may damage the brake caliper. 6. With the parking brake engaged, adjust the set collar position until 3/16” (4,7 mm) gap is measured between the set collar and brake link. 7. Reinstall the drive tires. Torque the lug bolts to 85-95 ft/lbs. (115-129 Nm). Remove the jackstands from under the machine. MOWING HEIGHT ADJUSTMENT The cutting height adjustment pin (A, Figure 37) controls the mower cutting height. The cutting height is adjustable between 1-1/2” (3,8 cm) and 6” (15,2 cm) in 1/4” (0,64 cm) increments. 1. Depress the deck lift foot pedal (B, Figure 35) until it locks into the 6” (15,2 cm) position. 2. Place the cutting height adjustment pin in the desired cutting height. 3. Depress the deck lift foot pedal then push the lock lever (C) towards the right to release the lock. 4. Release the deck lift foot pedal until it comes to rest against the cutting height adjustment pin. A B Figure 36. Parking Brake Adjustment A. Brake Spring B. Adjustment Nut C B A Figure 37.

Park machine on a flat, level surface. Disengage the PTO, stop the engine and engage the parking brake. Rear tires must be inflated to 18 psi (1,24 bar); front tires to 25 psi (1,72 bar). 2. Install the cutting height adjustment pin in the 33/ 4” (9,5 cm) position. See Figure 38. 3. To check the lift rod timing, measure and record the distance between the lift pivots and the rod pivots. Repeat for other side of unit. See Figure 39. 4. If the measurements for the rods and pivots are equal,, no further adjustment is required. If the measurements are NOT equal (greater than 1/8” (3,17mm) difference), adjustment is required, continue with Step 5. 5. Refer to Figure 39. To adjust the lift rods, adjust the 5/8” hex nuts on either side of the front lift pivot until the meas...
