Abstract: A brush mower head adapted to be carried by an articulating crane comprises:(1) a casing, adapted to be mounted to a crane(2) a motor carried by the casing, and(3) a drum with a center shaft mounted for rotation in the casing and powered by the motor, the axis for rotation in the drum in use being generally parallel to the ground. The drum is a cylinder having a length at least twice its diameter and has at least two hammer shafts running end to end parallel to the axis of rotation and being in balanced relationship one to another to minimize rotational imbalance of the drum. Hammers are mounted on the hammer shafts for free rotation thereabout in each of said wells. The hammers when the drum is rotating for mowing protrude by a centrifugal force beyond the surface of the cylinder and present a cutting edge to the brush being engaged.
