Frequently Asked Questions

How do flail blades work?

Flail blades are mounted on a rotating horizontal shaft inside a flail mower. As the shaft spins at high speed, the blades swing outward on hinges or fixed mounts and strike vegetation repeatedly, shredding it into small pieces. This free-swinging design allows blades to deflect when hitting obstacles, reducing damage to the equipment.
