A baling system, comprising a tractor and and a baler, operable to receive loose material, form the loose material into a bale, and eject the bale, wherein the baling system is powered by a power take-off associated with the tractor, and the baler comprising: a forming chamber having a discharge outlet, wherein the bale is located in the forming chamber; and a plunger operable to move in a reciprocating manner within the forming chamber from a front-dead-center position in which the plunger is furthest from the bale to a rear-dead-center position in which the plunger is closest to the bale; characterised in that the baling system further comprises a communication bus extending between the baler and the tractor and operable to transmit electrical signals; a plunger position sensor operable to sense a position of the plunger in the forming chamber; a power take-off speed sensor operable to sense a speed of the power take-off; and a control unit in communication with the tractor, the plunger position sensor, and the power take-off speed sensor, and operable to substantially automatically pre-position the plunger at a predetermined position after the power take-off is deactivated, wherein the control unit is arranged to receive a deactivation signal sent by the tractor to the power take-off over the communication bus to release a pressure in the forming chamber, to repeatedly apply a braking force to the power take-off for a first braking interval and ro remove the braking force for a second braking interval until the power take-off has slowed to a predetermined maximum speed based on information received from the power take-off speed sensor, and then constantly applying the braking force so that the plunger stops at the predetermined position within the forming chamber. a forming chamber having a discharge outlet, wherein the bale is located in the forming chamber; and a plunger operable to move in a reciprocating manner within the forming chamber from a front-dead-center position in which the plunger is furthest from the bale to a rear-dead-center position in which the plunger is closest to the bale; characterised in that the baling system further comprises a communication bus extending between the baler and the tractor and operable to transmit electrical signals; a plunger position sensor operable to sense a position of the plunger in the forming chamber; a power take-off speed sensor operable to sense a speed of the power take-off; and a control unit in communication with the tractor, the plunger position sensor, and the power take-off speed sensor, and operable to substantially automatically pre-position the plunger at a predetermined position after the power take-off is deactivated, wherein the control unit is arranged to receive a deactivation signal sent by the tractor to the power take-off over the communication bus to release a pressure in the forming chamber, to repeatedly apply a braking force to the power take-off for a first braking interval and ro remove the braking force for a second braking interval until the power take-off has slowed to a predetermined maximum speed based on information received from the power take-off speed sensor, and then constantly applying the braking force so that the plunger stops at the predetermined position within the forming chamber.
