UPDATE: Well shortly after discovering my new 4052R had this loader valve issue I decided I needed to do what I had to do. I hauled it back to my dealer and let him know that they hadn't been paid yet and wouldn't get paid until I was satisfied that the loader works like it should. And I also loaded up my 3720 that I thought I traded in on it and headed home. It took several days of the dealer waiting to hear from Deere's troubleshooting department (dtac I guess it is called) and I don't think they offered any help. I put the manager onto this site and told him to READ! I also suggested they hook loader up to rear SCV's and trait to see if it performed better, which they did and it did. They then finally talked it over with their very experienced technician, Brian, who had been out of the loop since all the farmers were putting the crops in. He recalled having to put a new loader valve in a 4066. FINALLY, upon looking the part up they saw that the valve had been subbed to a different part number not once, but twice. They put in the latest valve and VIOLA! It works great and we got the deal finished up and everyone is happy. I think had it not been for this forum that John Deere would have preferred to hang me out to dry, except they hadn't been paid and luckily my old tractor was still there to take hostage. If anyone needs assistance getting their loader fixed any further than this forum, don't hesitate to get ahold of me and I can try to help. I also better note that my dealer did a fine job on this, it just took a while for them to get tired of dtac dragging their feet.
