Abstract
An agricultural harvester includes a feeder house drivably coupled to a power source. The feeder house has a housing frame. A faceplate is pivotally coupled to the housing frame to facilitate a pivoting of the faceplate relative to the housing frame. A hydraulic cylinder has a first end connected to the housing frame and a second end coupled to the faceplate to facilitate movement of the faceplate relative to the housing frame. The hydraulic cylinder has a plurality of hydraulic ports for facilitating movement of the operating piston of the hydraulic cylinder, with at least a first hydraulic port of the plurality of hydraulic ports being connected in fluid communication with a hydraulic power system. A first accumulator containing a compressible gas charge is connected in fluid communication with the first hydraulic port of the hydraulic cylinder.
