[QUOTE="Daddygoose51, post: 116451, member: 14631"] I have just repowered my machine with a brand new Perkins motor, so that's out of the picture . My hydraulics all four cylinders slowly leak down over time. And that's an issue when I'm running along and loosing height on my attachments. I also noticed the other day that when i was on a pretty good slop i stopped and the machine was slowly easing down the hill until i hit the parking break. With all this said , is it possible that a relief valve is leaking by causing this? and would this same problem be associated with loosing hydraulic power after running the machine for several hours?
