Pattern select valve for control levers of a title work vehicle |
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.
