The tractor must also provide for 3-point hitch attachment Category I. The tractors rated drawbar PTO horsepower on a 3-point should be no less than 20 HP and no more than 50 HP.

NOTE: Ballast weights may be required to maintain steering control. Refer to your tractor’s operator’s manual to determine proper ballast requirements.
