EX-40 V2 Excavator Flail Mower | Eterra

The Eterra EX-40 V2 Excavator Flail Mower is built for roadsides, ditches, and other hard-to-reach areas, handling grass, brush, and trees up to 6 inches in diameter. Weighing 616 lbs, it features a Permco gear drive motor that delivers consistent torque and long-term reliability, preventing power loss or overheating during heavy use. The flail rotation speed of 1,900-2,300 RPM ensures a clean cut, while the electronically balanced cutting shaft reduces vibration and wear, keeping operation smooth and extending component life.

Equipped with 20 heavy-duty Y-Knife flail blades, each weighing 2 ¼ lbs, the EX-40 V2 cuts and mulches 4-5 inch material, with careful operation allowing for up to 6-inch material. The curved housing design directs material efficiently through the mower, preventing buildup and ensuring consistent mulching. AR400 skid shoes protect the frame when mowing at ground level, while a rubber vibration dampener absorbs impact to reduce strain on the machine and operator. With a tip speed of 12,743 feet per minute, the EX-40 V2 is built for fast, efficient cutting in demanding environments.

For added safety and performance, the EX-40 V2 now comes standard with a chain guard, providing protection from flying debris. It’s also equipped with Eterra’s new universal mounting plate, now included on all excavator attachments, making hookup quicker, easier, and more consistent across your fleet.
