Angle adjustment for fine precision grading and leveling
Turntable angle adjustmentTurntable angle adjustment

The turntable on the RB10, RB11, and RB21 Series Rear Blades makes it possible to adjust the angle to four different positions in both forward and reverse for those extra-tedious jobs.

Manually adjusting the blade forward makes it easy to handle leveling needs in a variety of soil conditions. Swing the blade around and use it to backfill or clear debris or snow.
