Hydraulic Flow Limitations – If there are additional features using hydraulic fluid on the machine (example: boom
leveling), there may be conditions where the hitch steering valve will require significant amounts of hydraulic fluid
(e.g., while turning). During these conditions, there may be limited hydraulic flow to other components, which can
result in reduced performance.
