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.
Claims11
An agricultural working unit, comprising:
- a hitch assembly;
- a pair of working heads,
- a pair of cantilever beams, each said beam being connected at one end with said hitch assembly for pivoting horizontally about an upright axis, each said beam being connected at an other end with a respective said working head for establishing a horizontal axis about which said respective working head may pivot vertically;
- and
- an adjustable linkage arrangement coupled between said beams for pivoting each of said beams relative to said hitch assembly between a working position, wherein said pair of cantilever beams extend in opposite directions from said hitch assembly in transverse relationship to a forward direction of travel of said working heads during operation of said working heads, and a transport position, wherein said cantilever beams extend parallel to each other in trailing relationship to said hitch assembly when the hitch assembly is being moved in a transport direction opposite to said forward direction of travel.
