To start the tractor, ensure the parking brake is engaged, the PTO is disengaged, and the throttle is set to the appropriate position. Turn the ignition key to the start position until the engine starts, then release the key.
For optimal performance, use a high-quality SAE 30 or 10W-30 motor oil that meets the API service classification SF, SG, SH, or SJ.
Change the engine oil after the first 5 hours of operation, and then every 50 hours or annually, whichever comes first.
Check the battery for charge, ensure fuel is available, verify that the spark plug is clean, and inspect the ignition switch and wiring connections for issues.
Regularly sharpen the blades, clean the deck to prevent grass buildup, and ensure the deck is level for an even cut.
Clean the tractor thoroughly, change the oil, add fuel stabilizer, disconnect the battery, and store in a dry place. Inflate the tires to the recommended pressure.
Use a tire pressure gauge to check the pressure. Refer to the operator's manual for the recommended PSI and adjust using an air compressor as necessary.
First, remove the mower deck. Then, release the tension on the belt tensioner, remove the old belt, and install the new belt following the belt routing diagram. Reinstall the deck.
Check for debris on the mower deck, inspect blades for damage or unbalance, and ensure all bolts and nuts are tightened to the recommended torque.
Loosen the throttle cable clamp, adjust the cable to ensure full throttle range, and then retighten the clamp. Verify operation after adjustment.
