Abstract: An agricultural machine system includes: an agricultural work vehicle; an agricultural work machine; and a control system operatively coupled with the agricultural work vehicle and the agricultural work machine, the control system including: a sensor configured for: sensing an operative parameter; and outputting an operative parameter signal corresponding to the operative parameter; a controller system configured for: receiving the operative parameter signal; determining, based at least in part on the operative parameter signal, a floatation pressure for an on-ground floatation of the agricultural work machine.

Abstract: Improved headers of a combine harvester are disclosed. The headers include structure in the form of upper and lower infeed conveyors which cooperate to maintain compressive contact with a flow of crop material that is being conveyed by the belts to the header outlet regardless of the flow characteristics of the mat of material being conveyed. The result is a consistent flow of crop material being passed through the header which results in more efficient harvester operation and more productive crop yield.
