Adjusting the Front Gauge Wheels WARNING Keep hands and feet away from the discharge opening of the cutting deck. The front gauge wheels on the mower deck are an anti-scalp feature, and should not ride on the ground. The front gauge wheels should be approximately 1/4-1/2" above the ground when the deck is set in the desired height setting. Using the deck lift handle, set the deck in the desired height setting, then check the gauge wheel distance from the ground below. If necessary adjust the front gauge wheels as follows: 1. Visually check the distance between the front gauge wheels and the ground. If the gauge wheels are near or touching the ground, they should be raised. If more than 1/2" above the ground, they should be lowered. 2. Remove the lock nut (a) securing one of the front gauge wheels (b) to the deck. Remove the front gauge wheel (b), hex screw (c) and spacer (d). See Figure 4-12. (b) (a) (d) (e) (c) Figure 4-12 Note: There are a pair of front gauge wheels on the nose of the 54" and 60" decks. 3. Insert the hex screw (c) into one of the three index holes in the front gauge wheel bracket (e) that will give the front gauge wheel (b) a 1/4-1/2" clearance with the ground. See Figure 4-12. 4. Note the index hole of the just adjusted front gauge wheel (b), and adjust the other front gauge wheel (b) into the respective index hole of the other front gauge wheel bracket (e). See Figure 4-12. Service Charging the Battery Test and, if necessary, recharge the battery after the tractor has been stored for a period of time. • A voltmeter or load tester should read 12.6 volts (DC) or higher across the battery terminals. See Figure 4-13. Voltmeter Reading 12.7 12.4 12.2 12.0 State of Charge 100% 75% 50% 25% Charging Time Full Charge 90 Min. 180 Min. 280 Min. Figure 4-13 • Charge the battery with a 12-volt battery charger at a MAXIMUM rate of 10 amps. 24 Section 4- Product Care Jump Starting WARNING Failure to use this starting procedure can cause sparking, and the gases in the battery to explode. 1. Connect the end of one cable to the disabled machine battery's positive terminal; then connect the other end of that cable to the booster battery's positive terminal. 2. Connect one end of the other cable to the booster battery's negative terminal; then connect the other end of that cable to the frame of the disabled tractor, as far from the battery as possible. 3. Start the disabled tractor following the normal starting instructions previously provided; then disconnect the jumper cables in the exact reverse order of their connection. 4. Have the tractor's electrical system checked and repaired as soon as possible to eliminate the need for jump starting. Servicing Electrical System Fuse There are two fuses located inside the left console. Lift the seat and look down at the left console to find the location of the fuses. One 30 amp fuse for the power steering and one 25 amp fuse the ignition, PTO, etc. These are standard plug-in type automotive fuses. Always use the same capacity fuse for replacement. Check the 30 amp fuse if the power steering is not working and check the 25 amp fuse for all other electrical problems. If you have a recurring problem with blown fuses, have the tractor's electrical system checked by your authorized service dealer. Safety Interlock System & Switch Operation Checks The following operational checks should be made daily: PTO Switch 1. Sit in the operator's seat. With the drive levers in the neutral position and the parking brake engaged, engage the PTO switch by pulling up on the knob and try to start the engine. The engine should not start. If it does, the PTO switch must be replaced. See your authorized service dealer. 2. If the engine does not start, disengage the PTO by pressing the knob down and start the engine. Now engage the PTO and the blades should rotate. 3. If the blades do not turn, the PTO switch must be replaced, the seat switch must be replaced or the electric PTO clutch must be repaired. See your authorized service dealer. Parking Brake Switch 1. Sit in the operator's seat. With the drive levers in the neutral position and the PTO disengaged, release the parking brake and try to start the engine. The engine should not start. 2. If it does, the parking brake switch must be repositioned or replaced. See your authorized service dealer. If the engine does not start, engage the parking brake and start the engine. Seat Switch 1. With the drive in the neutral position, the parking brake engaged and the PTO disengaged, start the engine. Now release the parking brake and raise up off the seat. Release the operator's seat and the engine should stop. If the engine does not stop, the seat switch must be replaced. See your authorized service dealer. 2. With the drive in the neutral position, the parking brake engaged and the PTO disengaged, sit in the operator's seat and start the engine. Engage the PTO and the blades should start to rotate. Raise up slightly off the operator's seat and the blades should stop. If the blades do not stop when you dismount from the operator's seat, the seat switch must be replaced. See your authorized service dealer. Electric PTO Clutch 1. This clutch operates when the engine is running, the operator is in the operator's seat and the PTO is engaged. This electric clutch is a normally trouble free device. If a problem develops and the blades do not turn, first check the 25 amp fuse, then investigate the wiring harness and the connections to the seat switch, the PTO switch and the electric blade clutch. Then check the seat switch, the PTO switch and finally the electric blade clutch. If the PTO clutch is still not working properly, see an authorized service dealer. Rear Tire Removal/Replacement 1. Remove the four lug nuts (a) to remove the tire. See Figure 4-14. (a) Figure 4-14 2. Reinstall the tires using the four lug nuts. See Figure 4-14. Torque the lug nuts (a) to 65-70 ft-lbs.
