When grading widths reach 14’ and beyond, strength matters. The Industrias America Lower Draft Arm Land Plane is built for high-horsepower tractors and serious surface work. These models connect directly to the tractor’s lower draft arms, eliminating top-link stress and allowing the frame to handle pure pulling force across wide spans. Reinforced dual 3” x 6” frame rails prevent flex, even under heavy loads. Four 6” x ½” reversible blades aggressively cut and redistribute material, while ¼” moldboards with 14” height maintain steady material flow. A 4” x 8” hydraulic cylinder allows depth adjustment without leaving the cab. With four ST225/75R15 implement tires for balanced support and transport stability, this machine is built for county roads, large agricultural operations, and commercial grading jobs. This is not a light-duty driveway grader — it’s commercial-grade equipment built to work.
