IronCraft 4500 Series: 7′ Heavy-Duty Grader Blade with Ratchet Offset

The IronCraft 4507 is a top-tier 84″ Heavy-Duty Grader Blade, meticulously engineered for tractors ranging from 50 to 75 horsepower. As our toughest rear blade, the 4507 is built to handle intensive land grading, professional leveling, and heavy-duty backfilling for commercial farms, construction sites, and municipal projects.

Designed for maximum versatility, the 4500 Series is Category 1 and 2 Quick Hitch compatible. Its defining feature is the integrated ratchet jack offset, which allows for 16 inches of lateral adjustment, providing precision control that manual pin-style blades cannot match.

Industrial Precision & Performance Features

• Triple-Axis Maneuverability: Features a 5-position angle adjustment (forward and reverse) and a 3-position tilt adjustment for complex road crowning and slope maintenance.
• High-Capacity 17” Moldboard: The 17″ tall blade is constructed from 1/4″ thick steel, optimized for rolling large volumes of dirt, gravel, or snow.
• Reversible High-Carbon Cutting Edge: Equipped with a 6” reversible and replaceable cutting edge to ensure a long service life under aggressive use.
