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us that their prices are rising, every order we make for materials needs to be revised because the last price is no longer valid, and for good reason.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 Excavator Mounted Hydraulic String Trimmer


The Eterra HST-1000 Excavator String Trimmer is high performance hydraulically driven string trimmer that is ideal for roadside use along fence lines, ditches, around guard rail posts, and anywhere that is hard to reach with bladed cutters. Now, due to the success of Eterra's signature Skid Steer line, this String Trimmer has been engineered for use on Excavators and Mini Excavators. The base model comes with Eterra's signature Excavator Mount, the SMB-1000.

Eterra uses a heavy industrial strength string that mounts into a specially designed head that supports the string so it cannot sheer off easily. The HST-1000 spins at up to 3500 RPM so special consideration had to be given to supporting the string and not letting it just shear off in the holder.  

Hydraulics: Eterra knows that with so many applications, you are going to have many different flows and pressures to contend with, included is a flow divider that allows operators to tune their trimmer to be just the right speed on their particular machine. Included is a special pressure valve that will not allow you to over pressure the motor making this last and last. Whatever you throw at it, the HST-1000 will just keep on going. The attachments runs on 5 - 15 GPM @3000 psi.

With a total weight of just 75 lbs. you can mount the Eterra HST-1000 String Trimmer just about anywhere.
