Abstract
A grader especially adapted for use in association with a tractor having a three-point hitch with the grader being capable of use in cutting, moving, spreading and leveling all types of soil, aggregate and the like. The grader can also be used to carry, spread and level hot and cold asphalt, soil, aggregate and the like. The grader has blades adjustable to a predetermined depth with the specific angle of the grader blades and the speed of movement in relation to the surface being worked determining the operational characteristics of the grader. The grader includes a pair of transversely extending blades oriented at a particular angle and being vertically adjustably attached to a pair of side frame members having ground engaging slide shoes along the lower surface thereof. The ends of the blades are vertically adjustably connected to the side frame members and provided with manually operated cam structures to adjust the blades vertically. The blades are mounted on an angled support bar in vertically adjusted positions to enable the position of the blades to be adjusted to compensate for wear.
