Found out why my tractor was running poorly, smoking etc....after pulling the head....gasket was burned thru on cylinders 2 to 3. What can cause that to happen?

Good chance the head is warped in that area. Take it to a good automotive machine shop and have them check it out. It doesn't have to be much for the gasket to fail. Hopefully it is the head and not the block.
I had one on a Japanese Massey. Had two machine shops say it was fine by running a parallel bar across it. Finally after trying everything else I went back and said do a skim cut on the head. They argued I didn't need it. I said it's my $75.00, do it. Got a very sheepish phone call a couple days later, "you were right" and it was in the area between the cylinders. Not much, probably less than the .005" that was allowable.
Problem fixed. Doesn't take much on a diesel with that high compression ratio.

I just came back from the machine shop now. The guy lightly sanded the head surface and checked it for straightness with his gauge. He said it looked OK. I think I may just get it shaved anyway. To be safe. The boss however, wants me to bring the head in and have the valves check guides and everything else.the engine only has 1200 hours on it. But it looks like the head may have been off another engine. I noticed on cylinder number 2 there are dimples in the bottom of the head. Something like it came off an engine that had a broken valve and it marred the finish of the head. I would like to attach a picture but I don't know how.
