The Eterra Sidewinder is a flail mower for mini skid steers. An open-face, deep cutter housing and 20 one-pound Y-knife blades cut grass and tangled brush without packing the housing, and a full-width steel roller with floating hydraulics lets the head follow ground contour. The mounting system slides the head to one side for fence and ditch line work.

The Eterra Sidewinder is the mowing head for crews knocking back rough growth on ground a full-size machine cannot get onto. It handles fence lines, ditch banks, trail edges and lot maintenance where the grass has gone past what a finish deck will take and the brush has not yet become a clearing job.

The housing is open-faced and deep, with a curved back that keeps material moving through instead of balling up under the deck. Blades are Y-knives on an electronically balanced carrier, which is what makes a flail head spin up smoothly and stay smooth as blades wear. A full-width steel roller sets the cut height and carries the head over dips rather than scalping them, and floating hydraulics let it ride the contour. The head sits close in front of the attachment connection so the weight stays over the carrier, which matters on a machine this size working across a slope. The whole mount slides sideways, so the cut can be pushed out past the tracks to reach a fence line the machine cannot straddle.

Common Applications

  • Cutting rough grass, brambles and light brush on maintenance rounds
  • Fence line and ditch bank mowing from a mini skid steer
  • Trail and right-of-way edge work
  • Land clearing follow-up on regrowth

Selection Notes

  • The head cuts up to 2 in of material in normal work. The supplier also publishes a 4 in cut capacity, qualified as achievable with careful operation.
  • Blade life is quoted at 500 hours, with the supplier's own condition that the head is not to be run into rock.
  • A mini universal mount is fitted as standard, and it is the default row in the buy box.
  • A Bobcat MT plate and a Mini ASV plate are offered in the buy box in place of it, and the price of the plate chosen is added to the machine.
  • Recommended material is medium to hard brush, grass and brambles.
  • Hydraulic flow is not settled: the supplier publishes three different ranges for this machine across three surfaces. Confirm the flow requirement against your carrier with the supplier before ordering.
