ABSTRACT:
In a flexible floating cutterbar cutting platform for a combine harvester, compact spring elements connected to cutterbar suspension linkage subassemblies are remotely controlled for adjustment of cutterbar counterbalance force so that pressure between the ground and the cutterbar skid plates may be adjusted, on-the-go, to suit varying harvesting conditions. Pinned pivotable connection of the cutterbar suspension linkage subassemblies to the rigid portion of the platform facilitate assembly and offer an improved method of adjustment of cutterbar attitude relative to the ground (tilt) when in working position.
