IronCraft 4400 Series: 7′ Professional Offset Grader Blade

The IronCraft 4407 is a high-capacity 84″ Offset Grader Blade engineered for tractors between 35 and 60 horsepower. This 7-foot rear blade is the ultimate choice for large-scale property maintenance, offering the width and mechanical flexibility required to move topsoil, grade long gravel drives, and clear heavy snow with ease.

Built for industrial-grade reliability, the 4407 is Category 1 Quick Hitch compatible. Its standout feature is the triple-axis adjustability, providing manual control over angle, tilt, and lateral offset—essential for professional-grade ditching, road crowning, and clearing alongside fence lines.

Advanced Precision & Technical Features

• Triple-Axis Maneuverability: Features a 5-position angle adjustment, a 3-position tilt adjustment, and a 5-position lateral offset for total grading control.
• 84-Inch Wide Coverage: The 7-foot width ensures you clear your tractor’s tire tracks even when the blade is at an aggressive angle.
• Lateral Offset Capability: Shift the blade outside the tractor’s footprint to grade safely next to buildings, steep banks, or fence posts.
• High-Capacity Moldboard: A 15-1/2″ tall blade constructed from 3/16″ thick steel allows for superior material rolling and high-volume moving.
