It is more of a linkage setup because it moves in interior lever up and down. Sorry about that. I saw this on a tractor in person and forgot to take a picture in person and this is the best I could find on the internet without knowing what it is.Rockshaft valve? Or linkage to rockshaft valve? Hard to tell in the picture.
By the way, I just noticed it. Welcome to the forum.Very handy indeed. I'm shopping for another tractor. Just making sure the new to us tractor has one or has a kit available for it.
