Hardscape Heavy does not create separate warranty coverage beyond the manufacturer’s warranty unless explicitly stated on the product page.

Returns are governed by our store return policy.

Please review our full return policy before purchase. If you have questions about return eligibility or manufacturer warranty coverage for a specific item, contact us before ordering.

The Eterra EX Series is an excavator flail mower for mulching grass, brush, and woody material in place rather than leaving windrows behind to rake and haul. It hangs off the excavator arm so an operator can reach a bank, a ditch, or a tree line and mulch it down in one pass. It handles hard brush, saplings, grass, and brambles, chopping the material fine enough to leave on the ground as mulch.

Twenty Y-knife flail blades spin on an electronically balanced shaft, so they chop and mulch on contact and fold back instead of bending when they hit a rock or hidden debris. A curved housing pulls the material up into the blades for a finer cut and better mulching, while A572 steel and AR400 skid shoes take the wear of working hard ground. The EX-30 and EX-40 V2 come standard with chain guards that protect the operator from thrown debris, plus a universal rail mount that speeds hook-up across excavator attachments. This is built for land-clearing, roadside, and property crews that mow and mulch heavy growth off an excavator and need blades and a deck that hold up to brush, brambles, and the occasional rock.

Common Applications

  • Mowing and mulching grass, brush, and brambles on land-clearing and roadside jobs
  • Cutting saplings and woody growth up to a few inches thick
  • Maintaining ditch banks, tree lines, and overgrown lots from the excavator

Selection Notes

  • Two models: the 30-inch EX-30 for excavators in the 7,000 to 14,000 lb class and the 40-inch EX-40 V2 for 9,000 to 20,000 lb machines.
  • Both run 20 Y-knife flail blades and come standard with chain guards and a universal rail mount.
  • Hydraulic hoses, couplers, and a machine-specific mount are included; an optional thumb saddle can be installed with the order.
  • Confirm the coupler and your machine's flow with the supplier before ordering.
