I did a quick internet search but didn't see where anybody else has had this problem. Hopefully the welder was just having a bad day and forgot to finish what he started. If it was me I'd be a bit leery after repairing it, but certainly wouldn't give up the tractor.
Unless it turned out to be a recurring problem.
