Application
AccuGrade™ ready, the Box Blade is designed for grading and leveling of large commercial properties, housing pads, roadways, and parking lots.
Curved Moldboards
Front and rear curved moldboards allow for material to roll and fold, improving capacity and performance. Flowing material will easily find low spots and improve grading and leveling performance.
Wear Indicating Cutting Edges
Wear indicating cutting edges feature 20% more wear material on the ground engaging section of the edge and also indicate when it is time to flip or replace the edge.
Dual Parabolic Mirrors
Dual parabolic mirrors provide full visibility to the front cutting edge allowing the operator to identify how much the blade is loading and see out to the corners of the Box Blade.
Centrally Located Electronics
Technology components are centrally located and simply route to their respective harnesses back to this location on the tool. Then, a single harness routes to the control module in the cab or on the tool.
Protected Hydraulic Valve and ECM
The hydraulic valve and ECM are enclosed and mounted within the frame of the tool, protected from damage.
