Are you mechanically inclined? What about doing it yourself??
I broke it. Help!

I see that you are in eastern Iowa. I live in Cedar Rapids and took it to Rexco out on Blairs Ferry. They seem to be fair. Pick it up next Wednesday.

On the quote to fix mine did not include any bearings, pinion, etc, just r and r and replace tube, your estimate sounds ok to me, just not something you like to hear. ( Sort of like when the tax guy called me yesterday.) Sounds like you had that much fun and work with it, not counting the fact that you still have the tractor. Good luck.
The good news is that it will be done tomorrow. The bad news is the price of repairs. The good news is that my tax guy gave me good news for a change. The best news is that I am leaving Thursday night to go spoonbill snagging at Lake of the Ozarks over the weekend. The bad news is the work is not getting done. Bad news =2, Good/best news=3. Looks like I am ahead of the curve right now!

Having sufficient counterweight in the rear is incredibly important to the health of the pinion gears in the front wheels of a 4WD tractor. Otherwise the front axle becomes the fulcrum point for all the weight. That is alot of stress on the front axle assembly--in fact, too much.
I once used too little weight in the rear (a small plow) while carrying heavy loads in the loader of a 4WD tractor and it quickly tore the pinion gears and one ring gear up in the front. When I bought my parts at the dealer, I chatted with the head JD tech. about the situation. He said it is a common error he sees (and repairs) and strongly advises people to add alot more weight to the rear. As counter-intuitive as it may initially seem, it makes perfect sense. The more weight in the rear, the more you are shifting the fulcrum and stress back to the rear axle, which is better able to handle the weight (think of a see-saw, with the heavier person on one side). The front end of the tractor will become physically lighter (it could be measured), and to that degree you are preserving the front end axle assembly. Your manual should tell you the limits on the rear, but if your 3-point hitch can lift it, you are likely still within its limitations.

I come back to my initial thought, I just can't see the loader having enough strength to break the front end.
I'm thinking it was a casting problem.

Now they tell me that they do not have a part and they are trying to find it. The guy says "I hope that we do not have to wait for it to get here from China". Wrong thing to say to a guy waiting for his stuff to be fixed. Not getting it fixed in a timely manner would add insult to injury!
I think that it is the front axle tube that he cannot get.

I agree that more weight behind the rear axle puts less stress on the front end for loader work. That fulcrum effect. If you have power steering you will not notice the lighter steering effort as you do with standard steering. Try to use as much weight behind the tractor as your FEL bucket will hold. Why yours broke could just have been it was a weak axle or you hit something with a front tire.

Do you have any pictures ? I'd like to see where the axle stops are situated . When an axle oscilates enough to touch the stops , it put's enormous strain on the axle as the leverage advantage is around 5-1 . Imagine using a crowbar to move a heavy object , using a block of wood as the fulcrum 2' back , you will not move the object . Move the block to within a few inches as you will overcome the object . Just asking as ive seen the stops mounted/cast too close to the pivot point .

Those of us with B2400's will appreciate any more particulars you can give. Like Iron Horse suspects, the axle stops are very close to the center pivot and there is limited oscillation before the axle is stopped. On ground wilth even small humps one or the other front wheel is often in the air or nearly so.
I am most interested in whether the part that broke first is one of the two brackets (front and rear) that bolt to the frame and serve as the bearings for the axle to pivot on, or whether it is the 1 1/2" or so diameter tube running front to rear through the center of the axle tube that fits in the brackets.
It sounds like a bracket broke first and then the axle tube pivot was damaged. Weight alone seems unlikely to break a bracket since the force on the bracket is upward into the base. But if the axle oscillates enough to strike the stop then the force on the bracket is downward against the farily thin outer shell of the bracket, and, as Iron Horse said, it is a large multiple of the actual weight because of the leverage.
I grew up on a South Georgia farm in the 1950's with tractors including the John Deere A, Farmall M, and Massey Harris 44. You could break them if you tried hard, but when doing the normal work they were designed for you never thought about babying them. My first Kubota was an L2900 which didn't seem too fragile (though clearly less sturdy than the old machines), but the B2400 was a shock. It looked solid, but several years of use have shown that it is not up to rigorous work.
We don't want to gain from your misfortune, but if we could learn the particulars of the failure we might be able to avoid the same problem in the future.
Thanks.
