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.

Features

• 40 inch cutting width for increased productivity
• 20 heavy-duty Y-knife flail blades weighing approx. 2.25 lbs each
• Permco hydraulic gear motor delivers consistent cutting power
• Electronically balanced cutter shaft for smooth operation and reduced vibration
• Heavy-duty A572 Grade 50 steel housing built for durability
• Chain guards included to reduce the throwing of debris
• AR400 skid shoes help protect the housing during ground contact

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?
