What is an excavator flail mower and how does it work?

Expert Answer

An excavator flail mower is a hydraulic mowing attachment that mounts to an excavator boom or stick for cutting grass, weeds, brush, and light woody growth in hard-to-reach areas. It works by using the excavator’s auxiliary hydraulic flow to spin a rotor fitted with flail knives or hammers. As the rotor turns at high speed, the flails strike and shred vegetation while the housing helps control discharge and improve safety. This setup is popular for ditch banks, pond edges, fence lines, roadside maintenance, and slope mowing where a tractor mower cannot safely reach. Performance depends mainly on hydraulic flow, pressure, carrier weight, and the head width. VANROCK manufactures and supplies excavator flail mower attachments for a wide range of carriers and can help match the mower to your machine’s hydraulic output, mounting geometry, and typical vegetation so you get the right setup and a practical quote.
