An apparatus including an upper triangular framework parallel to and spaced above a lower triangular framework in an aligned relationship, wherein a slide yoke is mounted between spaced, aligned upper legs of the upper and lower triangular frameworks, wherein the yoke is mounted to a rear vertical leg to vary a gap defined between a forward vertical leg and a forward vertical leg of the yoke. The apparatus further includes a first, second, and third support mount for securement to a three-point hitch of a tractor. A hydraulic member includes hydraulic lines mounted to a rear vertical leg and to a slidable forward leg of the yoke with the lines securable to a hydraulic system of an associated tractor.
