The HI-LIFT Box Blade Series represents the largest and most heavy-duty grading equipment in the lineup. Built for demanding applications such as road construction, large-scale land leveling, and heavy agricultural work, these pull-type box blades are designed to move and control large volumes of material efficiently. Each model features a tall 42.5-inch moldboard built from high-strength steel, allowing the blade to carry more soil, gravel, or aggregate in every pass. This increased capacity improves productivity when working on long farm roads, construction sites, or large land preparation projects. The reversible hardened steel cutting edge provides long wear life and maintains consistent cutting performance even in abrasive soil conditions. With two heavy-duty 4” × 16” hydraulic cylinders, operators can control the implement precisely from the tractor, helping maintain smooth grading and consistent material distribution. A lunette ring hitch (pintle compatible) provides a strong, reliable connection for high-horsepower tractors, while reinforced running gear with 11L16 tires and heavy-duty hubs ensures stability and durability during operation. Designed for operators who demand strength, capacity, and reliability, the HI-LIFT Series is built to handle the toughest grading and earth-moving jobs on the farm or job site.
