To start the tractor, ensure the parking brake is engaged, the PTO is disengaged, and the throttle is set to the mid or fast position. Insert the key and turn it to the start position. Release the key once the engine starts.
Use SAE 10W-30 motor oil for optimal performance. Ensure the oil is suitable for the temperature range in which the tractor will be operating.
The air filter should be checked every 25 hours of operation and replaced if it is dirty or damaged. Replace the air filter every 100 hours of operation or annually, whichever comes first.
First, check the battery connections for any corrosion or looseness. Ensure the fuel tank is not empty and the fuel valve is open. Verify that the PTO is disengaged and the parking brake is on. If these steps do not resolve the issue, consult the manual for further troubleshooting.
To change the mower blades, first disconnect the spark plug wire to prevent accidental starting. Lift the mower deck and secure it. Use a wrench to remove the blade bolts, replace the blades, and ensure they are securely fastened before lowering the deck.
Regularly sharpen the mower blades to ensure a clean cut. Adjust the cutting height to suit the grass conditions and avoid cutting more than one-third of the grass blade length at a time.
Check the transmission oil level every 25 hours of operation and top it up as necessary. Change the transmission oil every 100 hours or annually, and inspect for any leaks or damage.
Ensure the PTO switch is in good condition and connected properly. Check the PTO clutch for wear or damage and ensure the belt is properly tensioned and not slipping. If issues persist, consult the manual or a professional technician.
Stop the tractor immediately and allow the engine to cool. Check the coolant level and ensure the radiator is not clogged with debris. Inspect the fan belt for proper tension and wear. If overheating continues, consult a professional.
Clean the tractor thoroughly and remove any grass or debris. Change the oil and run the engine until it stalls to remove fuel from the carburetor. Disconnect the battery and store it in a cool, dry place. Cover the tractor to protect it from dust and moisture.
