I'll do my best, this is my first tractor, so I'm a bit hydraulically challenged myself. There's one cylinder on the top of the upper "jaw". It is located in the middle. The hydro goes back underneath the tractor, out the back, and into another valve I had installed. This second valve also runs the top and tilt for the box blade. This valve is mounted on a pipe "arm" which is u-bolted to the ROPS. This attachment has a view of the valve I'm referring to.
