Read the operating instructions for your tractor before use, and follow the manufacturer's safety guidelines and recommendations for proper use of the tractor.
Start the tractor with the gear shift in the neutral position.
Release the brakes, and depress the clutch pedal to the floor as far as it will go. This is engaging the clutch.
Increase throttle speed gradually, releasing the clutch pedal slowly and smoothly at the same time. Keep the two motions balanced until the tractor starts to move, and let out the clutch pedal steadily until it is fully released.
