Well John, hydraulic cylinders can move mountains, if they're in good shape and can get air-free fluid to them. The pump and filter look new? How's your hydraulic fluid level? Motor is out of box failure and has a bad seal(s) maybe? Maybe former owner thought the original motor was the problem, but wasn't? Maybe a control valve is failing or sticking under pressure and not moving to the position you're directing it, not allowing fluid to move?

"bucket won't move when someone puts a foot into it". Are you saying that you're releasing pressure and still won't go down, even when applying pressure? Double action control valve working with a two way cylinder, or two seperate control valves? I'm going to guess at one single two-way, and that may be where your problem is - sticking under pressure? If you meant "does move when someone puts a foot in it", then I'd be looking for leaking seals anywhere, including cylinders. But that's not what you said, so it doesn't sound like a cylinder is failing or has a leaky seal, otherwise would be dropping under load pressure instead of maintaining, or not budging to begin with.

I know nothing about any "skid ster", but with hydraulics, a motor moves fluid to whatever direction one allows it to flow with a control valve, and the cylinders move accordingly. A filter keeps dirt, debris, and moisture out.
