Looks good and a nice range of motion too.
My JD4100 goes to the shop on Monday to have Power Beyond installed. That will feed a dual valve mounted to the right of my seat. I already have the top link from Mark at CCM. I'll add the side link when I can. Like to have it, but it's not as important to me as the top link.
I didn't notice a valve in you pictures. perhaps I just missed it.
