Simplicity 1691698 6516H Parts Manual

To start the Simplicity 1691698 6516H Tractor, ensure the transmission is in neutral, the parking brake is engaged, and the throttle is set to half. Then, turn the ignition key to start the engine while ensuring the PTO is disengaged.
If the engine fails to start, check the fuel level, inspect the battery condition, ensure the spark plug is functioning, and verify that the safety switches are engaged. Also, examine the air filter for any blockages.
For uneven grass cutting, ensure the mower deck is level. Check the tire pressure and ensure the blades are sharp and properly installed. Also, verify the speed and height settings to match the grass conditions.
Regular maintenance includes checking and changing the oil, replacing the air filter, inspecting the belts, greasing the fittings, and sharpening the blades. Additionally, check the tire pressure and battery condition periodically.
To change the oil, run the engine to warm it up, then turn it off. Place a container under the drain plug, remove the plug, and allow the oil to drain. Replace the plug, and fill with new oil as per the manufacturer's specifications.
Excessive vibration could be due to unbalanced or damaged blades, loose components, or engine issues. Check the blades for damage, inspect the engine mounts, and ensure all bolts and nuts are tightened.
To adjust the drive belt tension, locate the belt tensioner and adjust the tensioning bolt as per the service manual instructions. Ensure the belt is neither too tight nor too loose to prevent slippage or wear.
The Simplicity 1691698 6516H Tractor is designed to run on unleaded gasoline with a minimum octane rating of 87. Avoid using ethanol blends above 10% to prevent engine damage.
To improve traction, consider using tire chains or weights. Additionally, ensure the tire treads are not worn out and adjust the tire pressure according to the manual's recommendations for better grip.
For off-season storage, clean the tractor thoroughly, change the oil, drain the fuel system, disconnect the battery, and store it in a dry, covered area. Consider using a fuel stabilizer if fuel remains in the system.
