Simplicity 2691454-03 Regent Parts Manual

To change the oil, ensure the engine is cool, then locate the oil drain valve at the bottom of the engine. Place a pan underneath, open the valve, and let the oil drain completely. Replace the oil filter and refill with the recommended oil type.
Check the battery for charge and connections. Ensure the fuel tank is not empty, and the fuel filter is clean. Also, inspect the spark plug for wear and replace if necessary.
Regularly clean the deck to prevent grass buildup. Sharpen the blades at least once a season, and check the belt tension to ensure proper operation.
Clean the tractor thoroughly, change the oil, and top off the fuel tank with a stabilizer. Disconnect the battery and store it in a cool, dry place. Cover the tractor to protect it from dust and moisture.
Ensure the tire pressure is even on all sides. Check if the mower deck is level and adjust if necessary. Inspect the blades for sharpness and replace if damaged.
Park the tractor on a flat surface and engage the parking brake. Loosen the lug nuts, lift the tractor with a jack, and remove the tire. Install the new tire, tighten the lug nuts, and lower the tractor.
Perform routine maintenance every 50 hours of operation or at least once a season. This includes checking oil levels, air filter, tire pressure, and cleaning the mower deck.
Check the coolant levels and refill if necessary. Ensure the radiator and cooling fins are clean and free of debris. Confirm that the fan belt is intact and functioning properly.
Consider using tire chains for additional grip. Ensure that the tire tread is not worn out and adjust the tire pressure to the recommended level for better traction.
Use unleaded gasoline with an octane rating of 87 or higher. Avoid using gasoline with more than 10% ethanol content to prevent engine damage.
