If you’re running a compact to mid-size excavator and need real brush clearing power without giving up control, the Eterra EX-30 Flail Mower is a proven solution. This is not a light-duty grass cutter. It is built to handle thick brush, fence lines, ditches, and overgrowth while leaving a clean, mulched finish instead of a mess.
The balanced cutting drum, heavy Y-knife blades, and reliable Permco motor give you smooth operation even when working at full reach. It is light enough for smaller machines but built tough enough for daily contractor use.
What size excavator is this best for?
This mower works best on excavators in the 7,000 to 14,000 lb class depending on hydraulic performance.
What hydraulic flow do I need?
You will need between 8 and 26 GPM for proper operation.
Does it require a case drain?
No. This mower does not require a case drain.
What material can it cut?
It can handle grass, thick brush, brambles, and small trees up to about 6 inches depending on conditions.
