Patent ID: 8621860

Claim:
A work machine comprising: 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; the fluid circuit including an operator-enabled mode selection switch operably connected to a controller; an electrical circuit comprising the operator-enabled mode selection switch and a second operator-enabled switch; and a first control valve in fluid communication with the attachment, the first control valve comprising a first bi-directional position, a uni-directional position and a second bi-directional position; in response to the mode selection switch being actuated to a bi-directional mode setting by the operator, the first control valve via the controller, is actuatable by the operator to one of the bi-directional positions, and electrical power is unavailable to the second operator-enabled switch of the electrical circuit; in response to the mode selection switch being actuated to a uni-directional mode setting by the operator, 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.
