  • Patent number: 4642976
    Abstract: This specification discloses a cutting head and mounting assembly for adjustably supporting the cutting head on a mower. The mounting assembly for the head permits easy adjustment of the height of the head above the ground, its horizontal angle with respect to the frame of the mower, and the inclination of the head from a horizontal to a vertical orientation or any angle of inclination therebetween. At the end of the head opposite its cutting flail members, there is a quick detach joint which allows, either an electric motor to be mounted and energized through a switch by electrical power available aboard the mower, or alternatively allows a cable drive to be mounted which drives the head from a friction drive mechanism taking power from the mower engine shaft, the friction drive being selectively engageable by means of a Bowden control cable. A guard to deflect cuttings away from the operation is mounted on the cutting head.
