The recommended oil for the Toro Wheel Horse 312-8 73363 Tractor is SAE 30 for temperatures above 32°F (0°C) and 10W-30 or 5W-30 for temperatures below 32°F (0°C).
The oil should be changed every 50 hours of operation or annually, whichever comes first.
The recommended tire pressure for the front tires is 12 PSI and for the rear tires is 10 PSI.
First, check the battery to ensure it is fully charged. Inspect the ignition switch and safety interlock system for faults. Verify that the fuel supply is adequate and that the fuel filter is not clogged.
Clean the tractor thoroughly, change the oil, add a fuel stabilizer to the fuel tank, and remove the battery to store it in a cool, dry place. Inflate the tires to the recommended pressure and cover the tractor to protect it from dust and moisture.
To replace the spark plug, first disconnect the spark plug wire. Use a spark plug wrench to remove the old spark plug. Install the new spark plug by threading it in by hand and then tightening it with the wrench. Reattach the spark plug wire.
To adjust the cutting deck, ensure the tractor is on a flat surface. Adjust the deck leveling links so the deck is level from side to side. Then, adjust the front deck links so the deck is approximately 1/4 inch lower in the front than the back.
Check if the blades are sharp and balanced. Ensure the tire pressures are even and that the deck is level. Also, inspect for any obstructions or damage to the deck components.
To replace the drive belt, first disconnect the battery. Remove the mower deck if necessary. Release the belt tension using the idler arm. Remove the old belt and install the new belt following the routing diagram. Re-tension the belt and reassemble any removed parts.
Remove the air filter cover and carefully take out the air filter. If it is a foam filter, wash it with warm, soapy water, and let it dry completely. If it is a paper filter, tap it gently to remove dirt or replace it if it is heavily soiled. Reinstall the filter and cover.
