[QUOTE="flyerdan, post: 114617, member: 2510"] If you put a double check valve in there, it will be in bypass no matter which direction you run it. The purpose of the check valve is to keep heavy rotating masses (like a bush hog) that spin at a fairly fast clip from grenading things when suddenly stopped. An auger, for example, doesn't need a safety check valve because it spins slowly, and if it binds the machine's bypass system protects everything. You should be able to reverse the sweeper with the brush in the air, for cleaning or whatever, but the oil will follow the path of least resistance and will bypass soon after it contacts the ground, depending on the rating of the check valve. If the brush spins fairly slowly, you might not need the check valve at all. It would depend on whether it keeps spinning after the flow is shut off. [/QUOTE]
