The recommended oil type for the Toro Wheel Horse 520Lxi 73545 Tractor is SAE 30 or 10W-30 for general use. In cold conditions, use 5W-30 for better performance.
It is recommended to change the oil every 50 hours of operation or at least once per season to ensure optimal performance and longevity.
If your tractor won't start, check the battery connections, ensure there is enough fuel, and inspect the spark plug for wear. Additionally, check the safety switches and fuses.
To adjust the cutting height, locate the cutting height adjustment lever typically found near the driver's seat and move it to the desired position. Ensure the tractor is on a level surface when making adjustments.
Regular maintenance checks should include inspecting the air filter, checking tire pressure, examining belts and blades for wear, changing the oil, and checking the battery's charge.
Uneven cutting can be resolved by ensuring the blades are sharp and balanced, the tire pressure is even, and the deck is level. Check for any obstructions or damage to the deck as well.
Use unleaded gasoline with an octane rating of 87 or higher. Avoid using ethanol-blended fuels greater than E10 as they can cause engine damage.
To replace the spark plug, disconnect the spark plug wire, use a spark plug socket to remove the old plug, and install the new plug by hand to avoid cross-threading. Tighten with a socket wrench and reattach the wire.
If the engine overheats, check the coolant levels, ensure there is no blockage in the air intake or exhaust, and inspect the oil level. Allow the engine to cool before performing any checks or maintenance.
To extend battery life, keep the terminals clean and free from corrosion, store the tractor in a dry place, and use a battery maintainer during long periods of inactivity. Regularly check the charge and water levels in the battery.
