Abstract

A construction machine including a first and second implement functions operable by a first and second actuator and a hydraulic system for controlling the actuators in response to operator controls. The hydraulic system includes a pump, a pressure line connected with the pump and pressurized by the pump, a tank line in communication with a reservoir, a first circuit including a first directional flow control valve in command of the first actuator to control the first implement function, a second circuit in parallel with the first circuit, the second circuit including a second directional flow control valve in command of the second actuator to control the second implement function, and a load sense line. The first circuit is not pressure compensated between the load sense line and the first directional control valve and the load sense line is connected to the second directional flow control valve with a pressure compensator.
