To start the Murray 309007x51C Tractor, ensure the parking brake is engaged, the PTO is disengaged, and the throttle is set to a mid or high position. Insert the key and turn it to the start position until the engine fires up. Release the key once the engine starts.
If the tractor won't start, check the battery connections for corrosion, ensure there is enough fuel, and verify that the spark plug is functioning correctly. Additionally, make sure the safety switches are not engaged.
Change the oil every 50 hours of operation or at the start of each mowing season, whichever comes first. Always use oil recommended by the manufacturer for optimal performance.
The Murray 309007x51C Tractor is designed to run on unleaded gasoline with an octane rating of 87 or higher. Avoid using ethanol blends higher than E10.
Uneven cutting may be caused by a dull or damaged blade, improper deck leveling, or tire pressure imbalances. Sharpen or replace blades, ensure the deck is level, and check tire pressures to resolve the issue.
Regularly inspect the blade for damage or dullness. Sharpen the blade every 25 hours of use or as needed. Replace the blade if it shows signs of significant wear or damage. Always disconnect the spark plug before performing maintenance.
Check for obstructions around the engine cooling fins, ensure the air filter is clean, and verify that the engine oil level is adequate. Clean or replace components as necessary to prevent overheating.
Clean the tractor thoroughly, change the oil, and add a fuel stabilizer to the gas tank. Disconnect the battery and store it in a cool, dry place. Cover the tractor to protect it from dust and moisture.
To adjust the cutting height, locate the height adjustment lever on the tractor. Move the lever to the desired position, ensuring both sides are set equally to maintain an even cut.
Regular maintenance checks include inspecting the air filter, checking tire pressure, examining the belts and blades for wear, and ensuring all bolts and screws are tight. Lubricate moving parts and check fluid levels regularly.
