    摘要: A work machine (10) comprises an auxiliary electro-hydraulic circuit (22) adapted to operate a hydraulic actuator (16) of an auxiliary tool (12) when the auxiliary tool (12) is attached to the work machine. The auxiliary electro-hydraulic circuit (22) is electrically controlled by a controller unit (24) in a proportional mode or a continuous mode.

    摘要: A backhoe control pattern selection arrangement is provided for a backhoe controlled by two control levers. The two levers are operatively connected to hydraulic systems that operate the boom and crowd hydraulic cylinders. An electrically operated valve block is electrically connected to a source of power and to a control switch, and hydraulically connected to the hydraulic systems. Changing the state of the control switch actuates the valve block and modifies the hydraulic systems to reverse the correspondence between the control levers and the boom and crowd functions.
