To start the Simplicity 1691959 GTH-L Tractor, ensure the parking brake is engaged, the PTO is disengaged, and the throttle is set to the 'Fast' position. Turn the ignition key to the 'Start' position until the engine runs, then release.
If the tractor does not start, check the battery connections, fuel level, and ensure the PTO is disengaged. Verify the spark plug is in good condition and inspect the fuses.
Regular maintenance includes checking the oil level before each use, changing the oil every 50 hours of operation, and cleaning the air filter every 25 hours. Check the tire pressure and inspect belts and blades regularly.
For uneven cutting, check the tire pressure for consistency, inspect the mower deck for levelness, and ensure the blades are sharp and not worn. Adjust the deck height if necessary.
Use unleaded gasoline with an octane rating of at least 87. Avoid using ethanol-blended fuels above E10 to prevent engine damage.
To engage the PTO, ensure the throttle is set to the 'Fast' position. Then, pull the PTO switch or lever to the 'On' position while the tractor is running.
If the engine overheats, immediately shut it down and let it cool. Check the coolant level and ensure the radiator is clean. Inspect the fan and belts for proper operation.
Thoroughly clean the tractor and remove any debris. Stabilize the fuel or drain the tank, change the oil, and disconnect the battery. Store in a dry, covered location to prevent deterioration.
To improve traction, consider using tire chains or weights. Check that the tires are properly inflated and use a lower gear to maintain better control on slippery surfaces.
Signs of a failing transmission include unusual noises, difficulty in shifting gears, and a loss of power. Regularly check the transmission fluid level and quality as part of maintenance.
