Abstract:
A pull-type mower conditioner type harvester has a mobile main frame carrying a vertically adjustable header or subframe which carries a plurality of harvesting components that extend between the opposite sides of the header, including a reciprocating sickle type cutter bar. The cutter bar includes a transverse support member that spans the width of the header and carries the cutter bar components, including a wobble type drive at one end of the cutter bar. The cutter bar is connected to the header by a pair of resilient mounting structures respectively connecting the opposite ends of the cutter bar to the opposite sides of the header, each mounting structure including a vertical, fore and aft link element that is connected to the header by a pair of fore and aft spaced rubber bushings and is connected to the cutter bar through a similar pair of fore and aft spaced rubber bushings that are respectively directly below the first pair of bushings, the mounting structure being relatively stiff in a fore and aft direction and in a vertical direction while being more flexible in a transverse or lateral direction to isolate vibrations due to the transverse or lateral reciprocating motion of the cutter bar sickle from the remainder of the harvester.
