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 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.
