The MTDC combination plow and grader is an implement designed to combine elements of the hillside plow and Beatty grader (Figure 25). The implement design also increases the grading width capability up to 4–ft (1200–mm) trail tread. The MTDC grader is built around a 60–in (1500–mm) main beam (hillside beam) that has a cutting point mounted just in front of the wing. In addition, the beam has a small keel and rock tooth mounted on the rear. The wing is 50 in (1300 mm) long. This grading width is adjustable from approximately 12 to 43 in (300 to 1100 mm) and can be adjusted vertically through a 6–in (150–mm) range with an onboard mounted shoe (Figure 26). Draft is adjustable in two ranges. The vertical draft can be adjusted through a range of 16 in (400 mm). The lateral draft can be adjusted through a range of 24 in (600 mm) (Figure 27). The implement is heavy, weighing over 250 lb (113 kg). It disassembles easily for packing; however, it is somewhat awkward to pack because of its length.
