The carbon steel market is poised to grow by 699.35 MT during 2020-2024 progressing at a CAGR of almost 8% during the forecast period." (Source: Business Wire)

This is what we are seeing all across the industry; day after day new emails from vendor's telling us that their prices are rising, every order we make for materials needs to be revised because the last price is no longer valid, and for good reason. The cost of steel materials has been steadily increasing throughout 2020, and it unfortunately has not slowed into 2021. The reduced capacities of companies in this industry due to Covid-19 health and safety regulations continues to have an impact. As a result, we are forced to increase our list pricing for 2021 and add a steel surcharge to off-set the rising costs that is projected to continue this year. We apologize for any inconvenience this may have on our close and prospective customers. We we will do what we can to keep our prices low when the opportunities are found, but right now we are left with little options.

Thank you for your understanding and continued support.


Product overview

Eterra Sidewinder 36" Flail Mower Head 30-35 GPM - Demo


This is a lightly used demo unit Sidewinder 36" Flail Mower. Built for the Eterra Raptor Boom mower, this attachment is ideal for cutting the toughest brush and maintaining roadside grass areas with ease. 

The open face and deep cutter design of the Eterra flail mower head makes it extremely useful for roadside mowing. The added reach and durability of this attachment is amazing. The power and speed of cut is outstanding. Cost of ownership is great because the teeth are readily available and inexpensive. It has a full width steel roller that allows you to float your machine hydraulics and the mower will follow the contour of the land. This gives you a far superior cut to using a large rotary mower that you have to balance and try to control over varying contours.
