Abstract
The present inventors have recognized that contaminants in hydraulic fluid in a hydraulic system of an off-highway implement can be efficiently filtered by a filtration system of the source of hydraulic power by conducting an operation which controls existing valves for precisely operating cylinders of the system to return the fluid to the source of hydraulic power through a connector with little or no fluid going through cylinders. Such an operation can be advantageously executed immediately following connection of the source of hydraulic power to the manifold of the implement.
