No power take-off is required. The small rotors are an advantage in two different ways over larger diameter rotors. First, the units extend only about 3 ft. behind the tractor for better maneuverability, and second, the small diameter forces them to spin at a higher RPM which disburses more material. Structural square tubing and angle iron frame provides the rugged platform onto which the rotors are attached. The RC-4 is great for use with ATV's or garden tractors.
Wheels provide transport by simply inverting the unit.
