Abstract
An agricultural baler including a movable density door; a fluid cylinder for moving the density door and including a fluid chamber and a piston disposed in the fluid chamber having piston and rod sides, and a cylinder rod coupled to the piston on the rod side; a fluid supply circuit for suppling working fluid to the fluid cylinder, the fluid supply circuit selectively connectable to the fluid cylinder such that, in a first fluid supply mode, the fluid supply circuit is connected to the fluid cylinder to supply working fluid to only one side of the fluid chamber and that, in a second fluid supply mode, the fluid supply circuit is connected to the fluid cylinder to supply working fluid to both the piston and rod sides of the fluid chamber. A control unit configured to: receive density-data; determine a supply-mode-control-signal; and provide the supply-mode-control-signal to the fluid supply circuit.
