2520 popping out of 4WD

Check to see if the shaft moves with the lever. Maybe they forgot the roll pin that goes in the lever and shaft. Something easy to check and cross your fingers that simple.

I think he was just referring to no ballast with that pic. Don't know why the tractor was on its side but a FEL without something on the 3PT is a big no no.

Update: I got my tractor back from the dealer today. I sure wish I could try adding the extra ballast weight to see if it has any effect, but I got it back in worse condition than when it went. I wasn't home when it was delivered, but I checked it out as soon as I got home. The 4wd lever now goes clear to the floor board and there is no longer any detent clicks, just a smooth glide from the the 2wd position to the floor. To make things worse, when the lever is down it is not engaged in 4wd even though the light it on. It's now screwed up more than it was. At least before I had 4wd even though it would pop out occassionally.

Tom, Smart move not letting them take your tractor!!!! Now the dealer is coming back out monday morning to pick my tractor up again for who knows how long. Needless to say I'm not happy!!!!!!

On the ballast issue: It may or may not work to prevent it from popping out of 4wd (yet to be determined) but I think the recomendation by Deere is a half *** solution to a design flaw. I've searched the internet extensively regarding this and no one is complaining much about their tractor of any brand popping out of 4wd unless they own a JD 2520. No one can tell me that it's unreasonable to expect your tractor to stay in 4wd with a modest load in the bucket with or without a ballast box. I agree that it is safer for stability purposes, but that isn't the question here.

Man that really stinks!!! I would suggest jumping thru the hoops and calling JD like I did. I wish I would have wrote everything down when I called! I do know with mine if I hold my heel on it, it won't pop out. I shouldn't have to do that though. I really believe that everyone has to start calling JD themselves and not the dealer.... I guess it will take somebody getting killed or severely hurt with a lawsuit for them to admit their is a problem, what a shame.... I really hope they get your tractor back to you soon at least the way it was before! I am not real confident in my dealer to fix the tractor, they didn't fix my chainsaw that I took to them twice and I have left 2 messages about it and they haven't called me back! There is another JD dealer closer to my home, maybe they are better at service? I would think that it wouldn't matter where you take it for service....

I've had my 2520 since August of 2006.
I have a 61" bucket on the FEL. I have moved many yards of heaping buckets of T-Pak with my 2520 and have gone down a fairly steep slope in 4WD with ballast box filled with concrete on while doing so. My tractor has never once popped out of 4WD. If it did...trade in and 3520 here I'd come!!

For the record, I dont care if your doing endo's down a slope in 4WD...it should break gears before it pops out of 4WD. Take any "proper ballast" statements and shove'em...it should never, ever pop out of gear.
EVER
EVER...EVER!!

Well, pardon me. I was responding to Tom's comment about both the potential of a serious accident, and the question of ballast, which I think is at the heart of this discussion.

I do own a 2520, and it has never come out of 4WD. However, I would not expect the front drivetrain to withstand the stress of slowing or stopping the tractor if the rear wheels became unloaded. The ballast discussion is about keeping the rear wheels doing the majority of the stopping.

Imagine if you had a two wheel drive tractor with an FEL, and treat the need for ballast the same as you would in that scenario. Let the front drive train supplement the traction of the rear wheels, not replace it.

As for the MFWD collar disengaging, Tom does have a valid point about why that should not happen. Relying on two small spring-loaded balls to keep the collar from moving may not withstand the shaft chattering under certain types of loads.

I stopped by the dealer today and they have my tractor apart waiting on parts. The mechanic wasn't there, but I spoke with the store manager. Appently they found something broken that wasn't noticed the first time they had it apart. They have been in contact with JD and think that this part was the cause of the 4wd popping out in addition to the 4wd not working at all when they brought it back last time. I don't know but I hope it comes back working properly this time with the 4wd fixed once and for all. I will speak with the mechanic and find out what part they are talking about and let you know in case this fixes the problem. I have not called JD yet, I'm kind of waiting to see if it comes back fixed this time. They are trying to get it back to me by Saturday.

I really hope they found the problem.... and I hope when you get it back and test the tractor that it is fixed!!! Makes you wander what they looked at the 1st time? Anyway thanks for the info I will be anxiously waiting to hear what the problem is / was...

I got my tractor back and so far so good. It hasn't popped out of 4wd since I got it back this most recent time. I talked to the mechanic and he said that he replaced a part called a "button". Aparently that part pushes against the detent. He said that he saw some issues with it that he didn't see the first time he took it apart. The good news is that he didn't have to split the tractor to replace, he was able to replace it by just taking off the side cover of the transmission where the 4wd shifter goes in. Maybe the new "button" and/or the tire pressure changes have solved the problem. I'm keeping my fingers crossed.
