Abstract:
A work machine includes a fluid circuit for use with an attachment configured to operate using one of a uni-directional flow and a bi-directional flow through the attachment. An operator-enabled mode selection switch operably connects to a controller. An electrical circuit includes the operator-enabled mode selection switch and a second operator-enabled switch. A first control valve is in fluid communication with the attachment. In response to the mode selection switch being operator-actuated to a bi-directional mode setting, the first control valve via the controller is actuatable to one of the bi-directional positions, electrical power being unavailable to the second operator-enabled switch of the electrical circuit. In response to the mode selection switch being operator-actuated to a uni-directional mode setting, the first control valve via the controller secures the first control valve in the uni-directional position, and electrical power is provided to the second operator-enabled switch of the electrical circuit.
