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.

An agricultural system including an agricultural baler and a control unit. The agricultural baler includes a drive system; a bale chamber defined by at least one movable density door; and at least one actuator for moving the at least one density door. The control unit is configured to: receive a routine-trigger-signal; determine an actuator-control-signal for adjusting a speed at which the at least one actuator moves the at least one density door in response to the routine-trigger-signal; and provide the actuator-control-signal to the drive system for driving the at least one actuator.

An agricultural system including an agricultural baler and a control unit. The agricultural baler includes a baler driveline; a rotatable flywheel; and a rotary input shaft connected by way of the baler driveline to the rotatable flywheel. The driveline includes one or more clutches for controllably transferring rotary drive between the input shaft and the flywheel. The control unit is configured to receive input-power-data indicative of a drive power available at the rotary input shaft; and determine a clutch-control-signal for controlling an amount of torque transferred from the input shaft to the flywheel bye the one or more clutches, based on the input-power-data.

A bale identification assembly for use with an agricultural baler having a first supply roll mounted on the baler providing a binding material used by the knotter system to bind the formed bale, wherein the binding material on the first supply roll is free of identification tags. The bale identification assembly includes a second supply roll mounted on the baler providing an identifying filament. The knotter system joins the identifying filament from the second supply roll with the binding material from the first supply roll while tying a knot to bind the formed bale.

A torque smoothing apparatus is utilized in conjunction with a large square baler (LSB), which includes a bale chamber, a plunger mounted for reciprocation within the bale chamber, and an LSB drive line. In embodiments, the torque smoothing apparatus includes a planetary gear train and a flywheel, which is mechanically coupled to the LSB drive line through the planetary gear train. An auxiliary motor having a motor output is mechanically coupled to the LSB drive line through the planetary gear train, while a controller is operably coupled to the auxiliary motor. The controller commands the auxiliary motor to selectively apply torque to the LSB drive line such that the torque applied by the auxiliary motor, taken in combination with a torque contribution of the flywheel, reduces variations in torque demands placed on a vehicle engine as the plunger reciprocates during LSB bale formation.

An agricultural harvesting machine having a multiple stage compression system includes first and second compression systems. The first compression system includes a first compression mechanism which partially compresses the crop material in a compression chamber. The second compression system includes first and second compartments each having at least one open end and positioned rearward of the compression chamber. The second compression system has a first position in which the second compartment is aligned with the compression chamber and the first compartment is operatively positioned with a second compression mechanism. The second compression system has a second position in which the second compartment is operatively positioned with a third compression mechanism and the first compartment is aligned with the compression chamber. The second compression system includes a binding system operatively associated with the second compression mechanism.
