Abstract
A mower has a pair of cutter heads which are pivotally supported by respective cantilever beams. The cantilever beams are pivotally coupled with a hitch assembly, which in turn is coupled with a traction unit via two lower lift arms and a floatable top link. The floatable top link allows the hitch assembly to float relative to the traction unit during transport. A hydraulic cylinder interconnected between the cantilever beams pivots the beams between a transport position and a working position. Stops on the hitch assembly limit pivotal movement of the beams relative to the hitch assembly.
