To change the oil, first warm up the engine to ensure the oil drains smoothly. Turn off the engine and allow it to cool slightly. Place an oil pan under the drain plug, remove the plug and let the old oil drain completely. Replace the drain plug and add new oil through the oil fill cap, checking the level with the dipstick.
Use unleaded gasoline with an octane rating of 87 or higher. Avoid using ethanol blends with more than 10% ethanol to prevent damage to the engine.
If your tractor won’t start, check the battery connections for corrosion and ensure they are tight. Verify the fuel level and that the fuel shut-off valve is open. Check the spark plug for wear or damage and replace if necessary.
It is recommended to sharpen the mower blades after every 25 hours of use or at the beginning of each mowing season for optimal performance and to ensure a clean cut.
Refer to the owner’s manual for the specific tire pressure recommendations, but generally, front tires should be inflated to 14 psi and rear tires to 10 psi.
Remove the air filter cover and take out the air filter. If it’s a paper filter, gently tap it to remove dirt or replace it if necessary. For foam filters, wash with mild detergent and water, then allow it to dry thoroughly before reinstalling.
If the tractor overheats, immediately turn off the engine and let it cool down. Check for obstructions in the air intake or cooling fins. Ensure there is sufficient engine oil and coolant, and inspect the radiator for blockages.
Locate the height adjustment lever on the tractor. Move the lever to the desired cutting height position. Always adjust the height on a flat surface and ensure the tractor is turned off and the blades are not spinning.
Before winter storage, clean the tractor thoroughly. Change the oil and run the engine to circulate the new oil. Add a fuel stabilizer to the gasoline, and run the engine to distribute it through the system. Disconnect the battery and store it in a cool, dry place.
To improve traction, consider adding tire chains or weights to the rear wheels. Ensure the tires are properly inflated and avoid mowing on steep slopes or excessively wet grass to reduce the risk of slipping.
