Shipping: LTL freight. Commercial delivery preferred.

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.

Shipping & Freight

For an order containing products from a single brand, shipping is a flat rate based on your order total:

  • Orders up to $5,000: $279
  • Orders $5,000 to $10,000: $347
  • Orders $10,000 and over: $517

These rates cover standard freight delivery to a commercial address. After you place your order, our team will confirm your delivery timeline within 1 to 3 business days.

Ordering from more than one brand? Multi-brand orders ship on separate freight and are quoted individually rather than at the flat rate above. Place your order or contact us first and we will confirm total freight before anything is finalized.

Liftgate service is not included in these rates. If your delivery location has no loading dock or forklift to unload the freight from the truck, liftgate service is required and will be added to your shipping charge. If you are unsure whether you need it, contact us before ordering.

Commercial delivery locations are preferred when available. Residential delivery, limited-access locations, and appointment scheduling may affect handling.

Lead times vary by product, manufacturer availability, and selected options. Some configured, special-order, or non-stock items require additional processing time before they ship.

Please inspect all freight shipments at delivery before signing. If you see visible damage, note it with the carrier and contact us as soon as possible.

If you need freight, delivery, or lead-time guidance before ordering, contact our team before you purchase.

Compatibility / Fitment

Compatibility varies by product type, machine setup, selected options, and intended application.

For machine-mounted equipment and attachments, buyers should confirm fitment before ordering using the relevant machine information, including model, attachment style, mount type, coupler type, hydraulic requirements, and any other product-specific requirements listed on the page.

Hardscape Heavy can assist with pre-order fitment guidance based on the information you provide. This guidance is limited to purchase and compatibility review before ordering and does not include field installation, hydraulic modification, fabrication, or on-site setup support.

If you are unsure whether a product will work with your machine or application, contact us before placing the order.

Returns & Warranty

Warranty coverage is provided by the product manufacturer where applicable. Warranty terms, coverage periods, exclusions, and claim procedures vary by brand and product type.

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. Because many products in this category involve freight shipping, special ordering, or configuration-specific selections, return eligibility may vary by product and condition. Special-order, custom-configured, used, damaged, or installed items may not be eligible for return.

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 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.
