Rockweel Trench Cutter

The Rockwheel single‐drum trench cutters are utilized
when the narrowest cut is required.
These rock and concrete trench cutters have the same
power as their twin drum counterparts but with all the
power concentrated on a single drum. We call this
power density and it equals high productivity!
The TC‐series trench cutters feature a heavy duty
stabilizing wheel with teeth that bite into the ground to
secure the cutter and minimize torsional stress on the
excavator arm. Be sure to check out the Operator’s
Guide below for optimal usage.
