What size excavator do I need for a flail mower attachment?

Expert Answer

The right excavator size for a flail mower depends on three main factors: operating weight, auxiliary hydraulic flow, and the width and weight of the mower head. In general, compact excavators can run narrower heads for grass and light brush, while mid-size machines are better for wider mowing widths, heavier rotors, and tougher roadside or embankment work. The machine must have enough hydraulic flow to maintain rotor speed under load and enough stability to safely handle the attachment at reach. Too small a carrier can lead to poor cutting, overheating, and control issues. Buyers should also confirm mounting dimensions, drain line requirements if applicable, and whether a case drain or specific coupler setup is needed. VANROCK manufactures and supplies excavator flail mowers for different carrier classes and can help size the attachment based on your excavator specs and intended application. If you use an OEM machine such as Caterpillar or Kubota, VANROCK is an independent manufacturer not affiliated with those OEMs.
