I wanted a hydraulic top link to go with my Ruegg 3 point and box blade and I got it all set up today. It took a bit of research to find all the right sizes and proper names of everything, so I thought I would spell it all out here for anyone else who wants to try. I bought the hoses to do a soft line, but decided to learn a new skill and run hard lines. Picked up 2 5 foot lengths of 3/8" mild steel tube, one 1/2" o ring boss to 37° jic adapter, one 3/8" o ring face to 37° jic, a few 3/8" tube sleeves and nuts. I picked this all up at a local hydraulic shop. I pulled a lock out valve off a 425 that I only use for mowing, so I could lock out the top link, which I suspect I will lock out some time when doing dirt work with my front blade at the same time as I'm using the box blade. I picked up pioneer style quick couplers that are compatible with the John Deere quick connects from the local rural King and the 1/4" npt to 37° jic adapters to hook the couplers onto the hard line. Grabbed a 14 gauge 2"x8" drop cut from a local sheet metal shop and had them put a 90° bend in it. I cut some off and drilled holes in it, then welded it across the 90° bend so it's quite strong. Overall I'm happy how the project turned out, I had to get kind of low with the hard line from the lock out valve. I could have picked up a right angle adapter to avoid it but no big deal. No leaks on the first try! Fun project.
