Abstract
An agricultural-implement hydraulic circuit includes a pump supplying pressurized fluid to a first service line and a second service line via a feed line and a device for varying the flow rate of the pump. A distributor valve is disposed between the first service line and the second service line, with the first service line and the second service line being connected and disconnected according to a position of the distributor valve. A hydraulic motor is coupled to the first service line through the valve and discharges fluid to a return line. A hydraulic actuator is coupled to the second service line. An indicator-valve assembly is coupled to the feed line, with the indicator-valve assembly including an indicator sensitive to pressure in the feed line such that the indicator indicates a predetermined pressure in the feed line to an operator.
