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.
Read More
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.
Read More
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.
Read More
Dual Front Wheels

Dual front wheels are mounted on an independent axle and on casters to provide stability in both directions of travel. These wheels are air filled and will provide balance for the blade in both automatic and manual operation.

Bolt-on Side Cutters and Wings

These improve the life of the tool with reversible side cutters and replaceable box wings. Both are bolt-on for simple replacement.
Read More
Standard Fixed Masts

Standard fixed masts provide great performance for single or dual laser technology configurations as well as supporting 3D technology.
