So I don't hyjack farm23's Thread on the Bro-tek thumb which is a great looking thumb btw, I'm posting this thread for any 180 owners that are thinking about adding a backhoe circuit or extra hydraulic circuit. Here are two pictures showing the 1637 3 spool valve installed. Since these pictures were taken I've installed the OEM 2 spool valve on the left side of the steering console. When I finish the plumbing on the new aux. circuit I will post a few pictures.
