ABSTRACT:
A brush cutting apparatus is mounted on an articulated boom assembly wherein the second boom member carries a pivot axis oriented orthogonally to the pivotal connections of the first and second boom members allowing generally vertical movement of the boom assembly. The articulated boom assembly preferably mounts a brush cutting head at the distal end of the second boom member to provide a greater range of flexibility and versatility in the operation of the brush cutting head. The orthogonal pivot axis is defined by a hydraulic rotary actuator carried in the central portion of the second boom member and enables the brush cutting head to be moved through an arcuate path generally parallel to the orientation of the second boom member as defined through a pivotal movement of the second boom member relative to the first boom member. The arcuate scything motion allows the cutting head to cover a greater range of ground for each pass of the prime mover while staying generally parallel to the surface of the ground. Furthermore, the hydraulic rotary actuator is operable to provide a bidirectional breakaway mechanism that is operable irrespective of which side of the prime mover the cutting head is operated.
