Abstract:
An agricultural round baler has an electronic control unit (ECU), a bale diameter sensor, a gate position sensor, and an electro-hydraulic valve that controls the flow to the gate lift cylinder. The ECU determines the height to which the gate must be raised based on the bale diameter. When the gate reaches the desired height, the ECU closes or restricts the electro-hydraulic valve for a brief period of time thereby momentarily slowing or stopping gate the gate. Momentarily trapping the bale between the gate and ground allows the bale to come to rest before the bale is released from the baler. The gate can then be fully opened so that the tractor and baler can be moved clear of the bale before closing the gate.
