STUPID ,STUPID, cracked what now ????

Must be an accomplished welder but most good welders with a lot of experiance can do it. No sweat job!

The welder should have a reverse polarity DC capability. You can just reverse the leads on a 200 AMP Lincoln gasoline welder etc if it is DC and lacks a reverse switch.

I have fixed Caterpillar transmission housings where the final drive was broken when trying to force ice frozen tracks to move.

To do it properly, the casting should be stripped down, and cleaned and pre-heated before welding, and if you're gonna do all that, it might be just as well to find a good used casting, and swap the guts of your's over to the donor case.

If you read the old post linked below you will find that you do not have to preheat to weld cast irom, but that you can "cold" weld cast iron IF you do it CORRECTLY. Cold welding is really the only choice for most of us because we do not have the facilities to uniformly heat large castings and them let then slowly cool. Hope you find the post interesting reading.

That bell housing flange is a structural part of the tractor, and I stand by may advice to replace it, and someone has found him a case at a reasonable price. Replacing it would be safer for him, and any subsequent owners of this tractor.
