Featuring the same 6″ x 12″ throat opening and 90-degree chipping angle as the standard Model 65XP, the PTO-powered version attaches via Category I three-point hitch (3/4-inch top pin and 7/8-inch bottom pins) or it can be a towable unit. It is recommended for equipment providing a range of 20 to 45 horsepower, operating in the 540 RPM range.
