If you’re running a larger excavator and need more coverage with serious cutting power, the Eterra EX-40 V2 Flail Mower steps things up in a big way. This is the next move up from the EX-30, giving you a wider cut, more hydraulic demand, and the ability to clear heavier material faster.
Built with a heavier drum, stronger shaft, and larger operating range, the EX-40 V2 is designed for contractors and crews that need to cover ground efficiently while still getting a clean, mulched finish. It handles thick brush, ditch lines, and overgrowth without leaving piles behind.
What size excavator is this best for?
This mower is best suited for excavators in the 9,000 to 20,000 lb class.
What hydraulic flow do I need?
You will need roughly 15 to 50 GPM depending on performance expectations.
Does it require a case drain?
No. Most modern excavators do not require a case drain for this mower when properly matched.
What can it cut?
It is designed for grass, thick brush, brambles, and small trees up to around 6 inches.
What makes this better than a rotary cutter?
Flail mowers produce a finer mulch and throw less debris, which improves safety and leaves a cleaner finish.
How long do the blades last?
Blade life depends on conditions but can reach several hundred hours when used properly and kept out of rocks.
