Funny I ran into this post today, Here is what happened to my
BX2350. Couple of weeks ago I had similar crack in the same location as this one, used JB weld, change the hydraulic fluid (or what left of it), filter clean screen…etc, no leak anymore. Couple of week later while mowing the grass I smelled a strong hydraulic fluid odder stopped the tractor and looked under and found the transmission case is two pieces.
So biggest mistake was to JW welding it and ignored the fact that the damage seem to come from the inside. That was very dumb.
Taking it to the dealer was out of the question, because I was expecting what happened with Genemcvay, at least with the cost not the way they dismantled the tractor this is really outrageous.
The main problem in my opinion was the damage happened in the differential, looking at the part diagram and found that I should start with the differential replaces what is broken, weld the case and of course hope nothing else broke inside. However the dealer will not do that, the dealer will replace the transmission case and that is a big job and required a mechanic with a very good skills obviously the dealer at Fort Smith doesn’t have.
The tractor has about 700 hours on it, couple of hundreds hour back the diff lock stopped working, I ignored that (who want a diff lock any way), not as dump like rushing to the JB weld thing but still dumb. I think that is when the problem started.
So it seem that something broke in the diff lock, jammed between the gears and the case and broke it.
Some googling today when I found this post and the ones below and start to think more and more than I am right.

Any way I just started taking it apart yesterday and will see how things will progress.
