What size excavator do I need for a hydraulic drum cutter?

Expert Answer

The right excavator size for a hydraulic drum cutter depends on three main factors: operating weight, hydraulic flow and pressure, and the type of material you want to cut. In general, drum cutters are available for compact excavators through to large carriers, but the attachment must be matched carefully so the machine can power it efficiently and handle the attachment weight safely. If the excavator is too small, cutter performance will be slow and hydraulic temperatures may rise. If it is oversized without the right hydraulic match, you may not get efficient production either. Buyers should check auxiliary hydraulic flow, working pressure, case drain requirements, stick and arm capacity, and whether they need a bracket for a pin-on or quick coupler setup. VANROCK manufactures and supplies drum cutters for a wide range of excavators and can help size the attachment correctly and provide a quote based on your machine and application.
