Blade Brake Check Mower blades and mower drive belt should come to a complete stop within five seconds after electric PTO switch is turned off. 1. With parking brake engaged, PTO disengaged and an operator in the seat, start the engine engine. 2. Have an assistant observe the mower drive belt through the open end of the left-hand arbor cover. Engage the PTO and wait several seconds. Disengage the PTO and check the amount of time it takes for the mower drive belt to stop. 3. If the mower drive belt does not stop within five seconds, perform the PTO Clutch Adjustment. If the belt still does not stop within 5 seconds, see your dealer. 26 00 Troubleshooting, Adjustment & Service NEUTRAL ADJUSTMENT If the tractor “creeps” while the ground speed control levers are locked in NEUTRAL, than it may be necessary to adjust the linkage rod. NOTE:Perform this adjustment on a hard, level surface such as a concrete floor. 1. Disengage the PTO, engage the parking brake and turn off the engine. 2. There are three (3) nuts on the linkage rod. The first two are to be used together to turn the rod and the third (towards the front of the machine) is used to lock the rod in place. Loosen the jam nut that locks against the clevis (B, Figure 28) and turn the linkage rod (A, Figure 28) 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 28) against the clevis when neutral is achieved. NOTE: This adjustment shouldnotbe performed while the machine is running.It may take several attempts to achieved neutral, depending upon how much the machine creeps. NEUTRAL POSITION AND RETURN SPRING ADJUSTMENT To determine if it is necessary to adjust the neutral position, perform the following steps. 1. Disengage the PTO, engage the parking brake and turn off the engine. 2. Move the ground speed control levers in the operating position, pull levers rearward and release. 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 29). Neutral Position Adjustment 1. Loosen the jam nut (D, Figure 29) locked against the clevis. 2. Turn the reverse return bolt (A, Figure 29) 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. 5. Once the lever alignment has been adjusted, lock jam nut against the clevis.

Jam Nut Return Spring Adjustment After adjusting the neutral position, lock the levers in the neutral position and measure the reverse return spring (B, Figure 29) length. This should be 2-3/8” (6,0cm) long. If not, hold the reverse return bolt (A, Figure 29) with a wrench while turning the spring position nut (C, Figure 29) until the measurement is achieved. 00 27 Troubleshooting, Adjustment & Service CUTTING HEIGHT ADJUSTMENT WARNING Before checking mower, shut off PTO and engine. Allow all moving parts to stop. Remove ignition key, then disconnect the spark plug wire and fasten it away from the spark plug. 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. DECK LEVELING ADJUSTMENT 1. Park the machine on a flat, level floor and engage the parking brake. Rear tires must be inflated to 15 psi; front tires to 20 psi. 2. Install the deck height adjustment pin in the 4" position. 3. Adjust the 5/8” hex nuts on either side of the front spring rod pivot (see Figure 31) until the rear lower edge of the mower deck directly behind the chain is 3-5/8" (9,2cm) from the floor. 4. The front lower edge of the mower deck directly in front of the u-bolts should be 3-1/2” (8,9cm) (48” & 52” decks) and 4-1/2” (11,4cm) (61” deck) from the floor. If not, adjust the u-bolts to correct the cutting height. Perform this step to both rods. 5. 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" (31,1cm). Be sure to measure the spring only. Adjust the length of the deck lift spring by tightening or loosening the (2) ...
