Simplicity 1691493 6516H Parts Manual

To change the oil, ensure the tractor is on a level surface. Remove the oil drain plug and allow the old oil to drain completely. Replace the drain plug, and refill the engine with the recommended oil type and quantity. Check the oil level with the dipstick to ensure it is correct.
First, check the battery for charge and connections. Ensure the fuel tank has fresh fuel and the fuel valve is open. Verify that the safety features, like the parking brake and PTO switch, are engaged. If the tractor still won't start, inspect the spark plug and replace if necessary.
Sharpen the mower blades every 25 hours of use or whenever you notice a decrease in cutting performance. Dull blades can tear grass instead of cutting it cleanly, leading to lawn damage.
Refer to the tractor's user manual for the recommended tire pressure, as it can vary between models. Generally, front tire pressure is around 12-14 PSI, and rear tire pressure is around 10-12 PSI. Always check the pressure when the tires are cold.
Maintain regular tune-ups, keep the air filter clean, and ensure that the tires are properly inflated. Also, avoid excessive idling and operate the tractor at optimal speed for the task at hand.
Clean the tractor thoroughly to remove debris and grass. Change the oil and replace the oil filter. Add a fuel stabilizer to the tank and run the engine for a few minutes. Disconnect the battery and store it in a cool, dry place. Cover the tractor to protect it from dust and moisture.
Locate the cutting height adjustment lever, typically found near the driver's seat. Move the lever to the desired height setting, ensuring both sides are adjusted equally for an even cut.
Check for debris lodged in the mower deck or wrapped around the blades. Inspect the blades to ensure they are balanced and not damaged. Verify that all mounting bolts and nuts are tightened properly.
Begin by checking the battery connections and fuses. Inspect the wiring harness for any visible damage or loose connections. Use a multimeter to test the voltage across different components to locate the issue.
Turn off the engine and disconnect the spark plug for safety. Remove the mower deck to access the drive belt. Release the tension on the belt by adjusting the tensioner pulley. Remove the old belt and install the new one, ensuring it runs correctly through all pulleys. Re-tension the belt and reinstall the mower deck.
