What size excavator do I need for a forestry mulcher attachment?

Expert Answer

The right excavator size depends on three things: operating weight, auxiliary hydraulic flow and pressure, and the diameter and density of the material you need to clear. In general, forestry mulcher attachments are commonly matched to compact, mid-size, and full-size excavators, but heavier carriers usually provide better stability, rotor recovery, and overall productivity. A machine that is too small for the mulcher may struggle to maintain rotor speed, run hot, or feel unstable when reaching out on slopes. Buyers should check available hydraulic flow, case drain requirements, coupler setup, guarding, and whether the excavator is intended for continuous high-load attachment work. If you mention an OEM machine brand such as Caterpillar, Komatsu, Kubota, or Bobcat, note that VANROCK is an independent manufacturer not affiliated with those OEMs. VANROCK manufactures and supplies excavator forestry mulchers and can review your machine specs to recommend the correct size and quote.
