1. An agricultural system comprising:
an agricultural baler, comprising:
at least one movable density door;
at least one fluid cylinder for moving the at least one movable density door and comprising a fluid chamber and a piston disposed in the fluid chamber to separate the fluid chamber into a piston side and a rod side, and further comprising a cylinder rod coupled to the piston on the rod side; and
a fluid supply circuit for suppling working fluid to the at least one fluid cylinder, the fluid supply circuit being selectively connectable to the at least one fluid cylinder such that, in a first fluid supply mode, the fluid supply circuit is connected to the at least one 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 at least one fluid cylinder to supply working fluid to both the piston side and the rod side of the fluid chamber; and
a control unit configured to:
receive density-data indicative of a desired bale density for bales produced by the agricultural baler;
determine a supply-mode-control-signal for setting the fluid supply circuit to the first or second fluid supply mode, based on the density-data; and
provide the supply-mode-control-signal to the fluid supply circuit.
