摘要： A row unit for a header of an agricultural harvester is provided that includes a first longitudinally extending stripping plate and a second longitudinally extending stripping plate each mounted on a frame and each having opposed stripping edges which define a gap between the first stripping plate and the second stripping plate. The row unit includes both operator-selected macro adjustment of the gap and automatic micro adjustment of the gap. The micro adjustment occurs on both deck plates. The micro adjustment is achieved through resilient members positioned functionally between the deck plates and the row unit frame.

摘要： A lateral tilt control system for an agricultural harvester may include first and second tilt cylinders coupled between a support structure and an implement of the harvester. The first tilt cylinder may include a first cap-side chamber and a first rod-side chamber and the second tilt cylinder may include a second cap-side chamber and a second rod-side chamber. The system may also include a first fluid line providing a flow path between the first cap-side chamber and the second rod-side chamber and a second fluid line providing a flow path between the first rod-side chamber and the second cap-side chamber. Additionally, the system may include a pressure relief valve coupled between the first and second fluid lines to allow fluid to be transferred between the first and second fluid lines when a fluid pressure within either fluid line exceeds a relief pressure setting.

摘要： In one aspect, a method is disclosed for transporting an autonomous agricultural vehicle and an operator-driven agricultural vehicle from a first agricultural work site to a second agricultural work site. Each of the vehicles may have respective front ends and rear ends, and each of the respective rear ends may include a respective hitch. The method may include arranging the autonomous agricultural vehicle and the operator-driven agricultural vehicle such that the rear end of the autonomous agricultural vehicle faces the rear end of the operator-driven agricultural vehicle. The method may include coupling the hitch of the autonomous agricultural vehicle with the hitch of the operator-driven agricultural vehicle. The method may include towing the autonomous agricultural vehicle behind the operator-driven agricultural vehicle with the rear end of the autonomous agricultural vehicle facing a forward travel direction of the operator-driven agricultural vehicle.
