Abstract
A grader blade unit is provided for ready attachment to small tractors in place of an underslung mower deck. A grader blade is attached to a turntable for pivotable adjustment to selected angular settings. An extensible draw bar affixed to the turntable has a front mounting yoke at its forward end. A rear mounting yoke is affixed to the turntable. The front and rear mounting yokes are adjustable in width and the drawbar is adjustable in length so as to accommodate the mounting links of different tractors. Wing sections hingedly connected to the opposite ends of the central blade are adjustable to selected angular positions relative to the central blade. Foot stirrups are removably affixed to the blade for controlling the slope of the blade in use.
