Abstract:
1. An agricultural harvester, comprising: a power source; a hydraulic power system coupled to said power source; a feeder house drivably coupled to said power source, said feeder house having a housing frame; a faceplate pivotally coupled to said housing frame to facilitate a pivoting of said faceplate relative to said housing frame on at least one axis of motion; a hydraulic cylinder having a first end, a second end, and an operating piston, said first end being connected to said housing frame and said second end being coupled to said faceplate to facilitate movement of said faceplate relative to said housing frame, said hydraulic cylinder having a plurality of hydraulic ports for facilitating movement of said operating piston of said hydraulic cylinder, with at least a first hydraulic port of said plurality of hydraulic ports being connected in fluid communication with said hydraulic power system; a first accumulator directly fluidly connected with said first hydraulic port of said hydraulic cylinder, said first accumulator containing a first compressible gas charge; a second hydraulic port of said plurality of hydraulic ports of said hydraulic cylinder connected in fluid communication with said hydraulic power system; and a second accumulator directly fluidly connected with said second hydraulic port of said hydraulic cylinder, said second accumulator containing a second compressible gas charge, thereby defining said hydraulic cylinder, said first accumulator and said second accumulator as a continuous bi-directional damping device.
