Tractor tilting head suppression measures
When the tractor just tilts its head, the front wheel just left the ground and you can step on the clutch pedal. Let the front wheel land and brake immediately. If the head tilt angle is large, but there is no danger of overturning, you can immediately step on the clutch pedal teeth, brake pedal, so that the tractor is stabilized at this height, and then the transmission is hung in neutral, and close the throttle to make the engine flameout, Loosen the brake pedal slowly, loosen the clutch pedal at the same time, and then depress the brake pedal so that the front wheel is slowly grounded and braked immediately. Note: Do not step on the clutch pedal without stepping on the brake pedal, otherwise the tilting locomotive will suddenly drop, which may cause serious damage to the front tires and other components. If the tractor tilts its head at a relatively large angle and there is a risk of overturning, the operator should quickly tilt the body to the side to prevent the steering wheel from coming out of the body and prevent it from being scalded by the boiling water in the tank, while depressing the clutch pedal teeth. The brake pedal stabilizes the vehicle at this altitude, and then closes the throttle to stop the engine. (If the engine does not turn off, the oil sump rises due to the back sloping of the oil pan, which can easily cause the oil to fly), and tries to leave the seat and stabilize it. Stay at the front of the car and hang up the neutral gear by repeatedly stepping on and releasing the brake pedal. Make the front wheel slowly fall to the ground. After the front wheel lands, it should immediately brake and remove some of the goods. Remedy after troubleshooting.
