Abstract

A power attachment is attachable to a power machine which has a power circuit. The power machine also includes an operator input device receiving an operator input and providing an output signal indicative of the operator input. The attachment includes a tool and an actuator, coupled to the tool, to drive the tool.
The actuator is also connectable to the power circuit of the power machine. A controller is operably coupled to the actuator and is operably couplable to the operator input device. The controller controls operation of the tool based on an operator input signal provided by the operator input device.
