To change the oil, first warm up the engine to ensure the oil flows easily. Turn off the engine and locate the oil drain plug beneath the engine. Place an oil pan underneath, remove the drain plug, and let the oil drain completely. Replace the drain plug and fill the engine with new oil through the oil fill cap, using the recommended oil type and amount specified in the manual.
If the tractor won't start, check the battery connections for corrosion and ensure they are tight. Verify that the battery is charged. Inspect the spark plug for wear or damage and replace if necessary. Ensure the fuel tank has fresh fuel and the fuel valve is open. If the problem persists, consult the manual for further troubleshooting steps or contact a professional.
First, check the PTO switch to ensure it is functioning properly. Inspect the drive belt for wear or damage and replace it if necessary. Make sure the battery is fully charged, as a weak battery can cause the PTO clutch not to engage. Additionally, check the wiring connections to the PTO clutch for any loose or damaged wires.
The recommended tire pressure for the front tires is typically around 14 PSI, and for the rear tires, it is around 10 PSI. Always check the tire sidewall or the owner's manual for the specific recommendations as they can vary slightly.
To replace the air filter, locate the air filter cover on the side of the engine. Remove the cover by unfastening the clips or screws. Take out the old air filter and clean the housing if necessary. Insert the new air filter and secure the cover back in place. Make sure the filter is correctly seated to prevent dirt from entering the engine.
Regular maintenance includes changing the oil and oil filter, checking and replacing the air filter, inspecting and replacing the spark plug, checking tire pressures, lubricating moving parts, and inspecting the belts and blades for wear. Regularly clean the tractor to prevent dirt buildup and ensure optimal performance.
To adjust the cutting height, locate the height adjustment lever typically on the right side of the tractor. Move the lever to the desired position, which corresponds to the cutting height you want. Ensure both sides of the deck are at the same height for an even cut.
Excessive vibration can be caused by unbalanced or damaged blades, loose parts, or engine issues. Check the mower blades for balance and sharpness, and replace them if damaged. Inspect the deck and chassis for loose bolts or components. If vibrations continue, consult a professional technician.
To replace the mower deck belt, first ensure the tractor is off and the parking brake is engaged. Remove the mower deck according to the manual instructions. Release the tension on the belt by adjusting the tensioner, then remove the old belt. Install the new belt following the belt routing diagram provided in the manual, ensuring it is seated properly on all pulleys. Reinstall the mower deck.
The Toro Wheel Horse 520-H 73502 Tractor is designed to run on unleaded gasoline with an octane rating of 87 or higher. Avoid using gasoline with more than 10% ethanol content to prevent engine damage. Always use fresh fuel to ensure optimal performance.
