When combined with the endlessly rotating Erkat rotation units, rotary drum cutters can be located in the ideal position to meet cutting requirements. All rotation units have a hydraulic swivel joint as standard allowing endless rotation.
Combining your standard Erkat drum cutter with a rotation unit is a simple procedure. Erkat rotation units can also be fitted to drum cutters from other manufacturers.
