ABSTRACT:
In the first preferred embodiment a flail cutter for a brush cutting machine comprises generally a shaft having a plurality of holes therethrough and a locking sheath also with a plurality of holes therethrough. The holes in the shaft and the holes in the locking sheath each receive a hanger, each hanger in turn holding a ring. Each ring holds a pair of flail blades. All blades are thus quickly attached to or removed from the shaft. After all blades have been attached to the shaft, the locking sheath is slid in one horizontal direction over the shaft to thereby lock the blades in attached engagement to the shaft. To remove all the blades, the locking sheath is slid in the opposite horizontal direction to release the blades from the shaft. In the second preferred embodiment, the hangers are attached directly to the shaft and the locking sheath is eliminated. Each hanger still holds the ring and the ring holds a pair of flail blades. The flail cutter is powered by a chain drive system. A method of providing a flail cutter for a brush cutting machine is also disclosed.
