I have my sights on a nice, very low hour, 4066R but it has this same bucket curl issue. Does anyone know if JD has fixed this or are they still explaining it away? Could be a deal ender for me.

Like a stated before my tractor has the same problems and both dealers near me can care less about my complaints. It's still under warranty so I called corporate they are supposed to be calling me back in a few days. Please everybody please never buy a John deere. Worst service ever.

OK. I recently traded for a new 4052R and didnt use loader for 5 minutes when I knew something wasnt right. Can anyone clue me in if this probelm ever got resolved or not? I hauled it back to my dealer and took old tractor home and have not paid a dime yet. I need to get this resolved or I am telling them to keep the dumb thing. I need to know names of dealers, reps, owners.... anything to get my dealer to stand up for me against the mothership. I farmed long enough to know that John Deere isn't the same reputable company it once was when it comes to standing behind their products and I refuse to let them have the upperhand again so need to push a little and get things done. If you like, we can exchange names and talk it over on phone too. Thanks everyone

My loader is equipped with the skid steer style mounts for attachments and not the john deere type. I was under the impression I could just use a skid steer bucket on it but thats not the case. Steer bucket sticks out so darn far that besides being trouble with hitting things I believe it changes all of the geometry as far as what it can lift and breakout force, etc. What is everyone else using for buckets? I have a standard bucket coming for the loader to see how it performs with one of those on. I don't have a clue why they weren't aware that a skid steer bucket won't work with it but I guess if it has that style mount one just assumes, as I did. The whole situation is a nightmare, lol.... Also, has anyone tried plumbing the loader to the rear scv's? I am guessing if one did that the loader will curl and lift like crazy if the loader valve is truly the problem... or am I washed up? Also, I am looking into buying a new Case/IH tractor and loader as a contingency plan if or when I get sick of the runaround. Does anyone know of problems with these tractors? Probably a Farmall 50. Buying red will be a bitter pill to swallow for me but I gotta do something....

We are in the process of purchasing one of the 40 series tractors. Thanks to all for posting about these issues.

I have a brand new 4044R (built in March, 2017) with the H180 MSL FEL and it does NOT exhibit any of the issues listed above.

I can lift the entire front of the tractor off the ground with the bucket flat on the ground and I can raise the tractor just by curling the bucket. It goes up and stays. No issues what so ever. I can do this even at idle.

The hydraulic systems are the same between 4044/4052/4066's - the loader valves are different depending on what FEL you have, the D170 or H180.

Hmmm.... I believe my loader valve was already in the tractor before they even got me a loader to put on it

Yes, you are right. I was thinking about the difference between the M with the D170 and the R with the H180.

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.
