Abstract
A header assembly for an agricultural harvesting machine having a traction unit comprises a cutter, a main frame that supports the cutter, a float cylinder configured to be coupled between the main frame and the traction unit, an accumulator, and fluidic circuitry that fluidically couples the accumulator to the float cylinder. The fluidic circuitry is configured to provide a first flow of pressurized fluid under pressure to the float cylinder, so the float cylinder exerts a float force on the main frame, and, based on a control input that corresponds to a lifting operation of the header assembly, provide a restricted flow of fluid, that is restricted relative to the first flow, between the float cylinder and the accumulator.
