How do I safely stop the tractor and engage the parking brake?

To stop the tractor, move the throttle control between half and full speed before stopping to avoid engine backfire, then turn the ignition key to the 'STOP' position and remove the key. To engage the parking brake, depress the clutch/brake pedal all the way down, pull the parking brake lever up, then release pressure from the pedal — the pedal should remain in the brake position. Always remove the key when leaving the tractor to prevent unauthorized use.
