ABSTRACT:
A mower for cutting grass, brush and the like includes a substantially U-shaped frame which is to be pivotally connected to the front end of a vehicle. The frame has a pair of arms with free ends extending in the direction of travel when the mower is in a cutting position. The frame is movable between the cutting position and a non-operating position during which the vehicle may be driven over roads without removing the mower. A rocker arm is pivotally connected to the free end of each of the arms of the U-shaped frame, and a cutter assembly, including cutter blades, is suspended from the U-shaped frame being pivotally connected between the rocker arms. The cutter assembly has a support shoe at each end to which the rocker arms are pivotally connected. The points of pivotal connection of each of the rocker arms to the free ends of the U-shaped frame are located in front (with respect to the directon of travel of the mower) of the connection of the rocker arms to the support shoes. A third rocker arm extends parallel to and behind one of the other rocker arms and is also pivotally connected at one end to one of the pair of arms of the U-shaped frame and at the other end to one of the support shoes of the cutter assembly to form a parallelogram linkage between the cutter assembly and the arms of the U-shaped frame.
