I can't try the cylinder on the tractor because I don't have the correct couplers on it. The picture in my previous post is from the eBay auction so you don't see anything wrong with it. Here are a few pics to try and show what I am talking about. I can pull on the piston rod and fluid and air will bubble out of the seal. If you look close in the second pic you can kind of see where the seal is broken. (it looked better before it was resized.) I don't see any way to take this apart, it looks all welded together.
