A lateral flotation mechanism for the header on a combine harvester is disclosed wherein a pair of springs provide a counterbalancing force to stabilize the pivotal movement of the header about a centrally disposed pivot from externally imposed loads.

A lateral flotation mechanism for the header on a combine harvester is disclosed wherein a pair of springs provide a counterbalancing force to stabilize the pivotal movement of the header about a centrally disposed pivot from externally imposed loads. After the external load is removed from the header, the springs effect a rotation of the header about the center pivot to return the header to a predetermined stabilized position. The compression of the springs is adjustable to pre-load the springs and compensate for any imbalance in the header.

In a harvester apparatus having a base harvesting unit, a header for receiving and feeding crop material to a combine harvesting unit, a feederhouse connected to said base harvesting unit and a header support means interconnecting said feederhouse and said header, including pivotal means for support

In a harvester apparatus having a base harvesting unit, a header for receiving and feeding crop material to a combine harvesting unit, a feederhouse connected to said base harvesting unit and a header support means interconnecting said feederhouse and said header, including pivotal means for supporting said header for rotation about a substantially longitudinal axis relative to said combine harvesting unit, the improvement comprising: means operably disposed between said feederhouse and said header for applying a predetermined stabilizing moment in at least one direction about said longitudinal axis, the arrangement being such that in the absence of any external load, said header is maintained in a stable predetermined relationship relative to the combine base harvesting unit with respect to pivotal movement about said longitudinal axis, said header being pivotable about said longitudinal axis upon an application thereto of an external force causing a turning moment greater than said stabilizing moment, said means for applying moment acting to return said header toward said predetermined relationship when said external force is lessened.
