I've hesitated for a long time, about asking that question. I feel like a fool, but I can't figure it out. I need to put it up for the winter. It's a Vermeer V rake. It folded down, just fine, when I made my last cutting of hay. I noticed while taking, it wouldn't fold back up. I have tried everything I can think of (which ain't much). Stupid thin won't fold back up. Cylinder moves about an inch, and no more. I've stuck the hydraulic ends in countless different times. Just won't fold up. No fluid squirting anywhere, no visible sign of anything wrong. It can be locked up for transport, but not in the down position. I don't have another cylinder to see if that is actually the problem.
