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

The tough, tubular steel frame on Frontier™ RB Series Rear Blades is perfect for grading. Its full-radius moldboard more than handles landscaping needs.

 

NOTE: This applies to all RB Series Frame except the RBL Series.

Hitch attaches quickly and efficiently

The Frontier™ RB10, RB20, and RB21 Series Rear Blades are all iMatch™ quick-hitch compatible and compatible with Category 1 hitches. Both systems provide a quick, efficient hookup.

Reversible cutting edge for longer wear life

All Frontier RB Series Rear Blade cutting edges are reversible, featuring bevels on both edges to give the blade twice the work life.

End plates allow Frontier™ RB Series Rear Blades to hold more material while dragging it from place to place. This is ideal for leveling uneven terrain.

 

Each of the field conversion kits are for a pair of end plates and prevent the blades from windrowing material when backfilling or leveling.

Optional skid shoes increase cutting edge life

Skid shoes increase the life of the cutting edge on all RB Series Rear Blades and avoid damaging the work surface while cleaning corrals or plowing snow.

 

NOTE: Skid shoe style shown in image above used with RB2060, RB2072, and RB2084 models.

 

The skid shoe kits include one pair and allow the blade to ride on the shoes at a set height to allow the operator control of the blade depth.

 

The bundles listed below identify the rear blades they fit.
