Doubling your speed increases the possibility of an overturn by about four times. Remember to lock your tractor's individual wheel brakes together for road travel. Applying one brake too strongly can swing the tractor sideways, causing it to be rolled by the wagon. The tractor can also be forced into a spin with the brakes locked together if the brakes are not adjusted correctly. The owner's manual or your tractor dealer should be able to help you adjust the brakes to apply an equal amount of braking force when the brakes are locked together.
Sharp turns can also result in an overturn, especially if the wagon is loaded.
When a sharp turn is made, the trailed equipment will try to continue in a straight line, which can jackknife and roll the tractor. Use warning lights when possible. Signal all turns with lights or hand motions. To allow traffic to pass, pull off onto the shoulder and stop. Don't drive on the shoulder.
