Excavator Mounted Hydraulic String Trimmer | Eterra

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.
