CHECKLIST FOR AN ANNUAL CHECK-UP Clean the tractor and deck thoroughly using an auto wash soap or household detergent. After washing, blow off all electrical connections and switches with compressed air. Strip tractor and deck for repainting. If the paint is in good condition, only a touch-up may be needed. Clean the inside of the catcher box with an automotive whitewall cleaner. These cleaners contain bleach that will remove some of the stains. This process should be done periodically during the mowing season. Remove the engine. Have an authorized service technician evaluate it and perform the needed tune-up, repairs or overhaul. Check all of the pulleys for wear and damage. Replace as needed. Check the idler pulleys for wear and the bearings for smooth operation. Check all idler arms for straightness and idler pulley alignment with the belt. Replace all of the belts. This is cheap insurance. Check over all of the springs. Replace any that are stretched, bent or show any signs of damage. Check all gearboxes for proper oil level, and for damage and leaks. Check the seals closely. Repair or replace as needed. Change the gear oil in any gearboxes as specified in the Owner's Manual maintenance chart. Examine the throttle, choke and parking brake cables. Replace any that are damaged. Lubricate the cables with silicone or another non-petroleum lubricant. Clean the blower thoroughly. Check for worn impeller blades and housing. Check the bearings by making sure the impeller turns smoothly. Repair or replace as deemed necessary. Check all of the switches (safety, light, implement, accessory and ignition) for proper operation. Replace any that are questionable. Check the wiring harness for any damage. Repair or replace. Check all of the plugs and connectors for damage and corrosion. Clean or replace as needed, and apply dielectric grease to protect the connection. Check all of the solenoids, relays, lights, gauges and circuit breakers for proper operation. Examine the tires and valve stems carefully for cuts, cracks, nicks or bulges. Make sure there is sufficient tread for good traction. Replace any bent or cracked wheels, or wheels with worn lug mount holes. Replace any worn or damaged chutes (deck, body and catcher). Replace the hydro fans if they show any signs of damage, and certainly if any blades are missing. If the operator's seat is damaged, replace it or have it repaired. Your back is not replaceable. Check the deck caster wheel bearings and pivot bushings. Replace any deck height adjustment bushings that are worn, broken or missing. Install a new set of sharp and balanced blades. After everything is reassembled, check all adjustments carefully: PTO clutch, blade brake, transmission control, safety switches, fuel solenoid and cables (throttle, choke and parking brake). Finally -- give your mower a good coat of wax.
