Disclosed are excavators or other power machines having a lift arm structure with a bucket coupled to an arm to pick up material during a digging or scooping operation, and a bucket cleanout devices to aid in removal of material from the bucket. The bucket cleanout devices include components which are rotatably coupled to a support structure, such as the arm, an implement carrier and/or the bucket and configured to aid in removal of material during a material dumping movement of the bucket.

Bucket cleanout

A power machine includes a carrier comprising a supporting frame, an operator compartment and a joystick controller disposed in the operator compartment and configured to generate movement signals in response to operator movement of the joystick controller. An attachment is detachably coupled to the power machine. A carrier control unit is disposed on the carrier and configured to receive the movement signals from the joystick controller. An attachment control unit is disposed on the attachment and configured to control movement of the attachment. A network is coupled to the carrier control unit and to the attachment control unit and is configured to carry instructions from the carrier control unit to the attachment control unit. A state selection input is disposed in the operator compartment to select one of at least two operational states including a carrier state and an attachment state. In the carrier state, the carrier control unit is configured to control operation of the carrier in response to operator movement of the joystick controller. In the attachment state, the attachment control unit is configured to control operation of the attachment in response to operator movement of the joystick controller.
