Looks an awful lot like KennyD's doesn't it? That's not a bad thing as he did a wonderful job on his. And he did it himself too.
I like it a lot as I can make adjustments on the box blade while in motion. I was out this evening working on our gravel road and it's a wonderful thing.
I do find that it's esay to hit the lever with my elbow and have the cylinder move when I didn't intend it to.

Little bit of a lesson I need to learn.
I'll have to add a tilt cylinder in the future. Already thinking that now that I have 'extra' hydraulic outlets I could add a grapple, or operate a 3 point log splitter, or operate a dump bed wagon, or....
I do have a confession though.

I was reversing the location or the pilot valve on the cylinder to gain more hose clearance against the tractors frame and cross threaded the banjo fitting.

Now it leaks like a sieve, but the rear of the tractor will never rust. I guess I'll need to order another cylinder from Mark as I don't think it can be repaired.
At least I got to play with it for a while before I discovered the problem.
