Abstract

A mobile machine (100) includes a frame (104), a plurality of crawlers (108) coupled to the frame, a plurality of actuators (118) operably coupled to the plurality of crawlers (108), and a fluid circuit (122) configured to supply a working fluid to each actuator (118) of the plurality of actuators. The fluid circuit (122) includes a plurality of hard plumbed sub-circuits (402) and a floating sub-circuit (428). The plurality of hard plumbed sub-circuits (402) are connected to the plurality of actuators (118) to allow flow of the working fluid to and from the plurality of actuators (118). The floating sub-circuit (428) interconnects the plurality of actuators (118) and allows the working fluid to flow between the plurality of actuators (118). The floating sub-circuit (428) includes floating valves (430) that control the flow of the working fluid in the floating sub-circuit (428) independent of the flow of the working fluid in the plurality of hard plumbed sub-circuits (402).
