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.

Abstract: An open center hydraulic system that includes a variable displacement pump having an inlet, an outlet and a sensing port, the pump configured to provide reduced fluid flow in response to a predetermined fluid pressure differential between the outlet and the sensing port. A first fluid circuit and a second fluid circuit each serve as signal lines with the pump sensing port. During operation of the second fluid circuit, reduced fluid flow from the pump outlet is achieved as a result of the sum of induced fluid pressure reductions of respective controlled pressure reduction devices approaching the predetermined pump fluid pressure differential.
