ABSTRACT:
A heavy duty brush cutting machinery having vehicle mounted brush cutters mounted on a boom extending outwardly from the vehicle. The cutter head assembly is comprised of a generally circular rotary cutter blade, a blade-rotating motor and drive shaft, and a semi-circular cutter blade shroud mounting the motor and the drive shaft. The shroud is comprised of a top deck mounting the blade, motor and drive shaft. The top deck has a first peripheral edge encompassing an obtuse arc, a second segmental edge lying radially outwardly from the first edge and non-radially across the plane of the underlying cutter blade, and a third segental edge extending from the first edge and intersecting the second edge at an obtuse angle. The shroud includes an anvil cutting edge provided at the leading edge of the top deck's third segmental edge to sever or dislodge oversized objects from the blade before the object can be carried into the shroud enclosure.
