Rating wise you shouldn’t be able to break 1/4” chain with your tractor but you can. I have broken grade 70 1/4 chain. I think it is so small that it can easily be damaged which weakens it. 5/16” is a much better choice in my opinion. It is still plenty light to handle.
When you are dragging a log and it suddenly hangs up on a stump or other immovable object, it's not hard to brake a 1/4" chain. When you have a few thousand pounds of tractor moving along, it isn't going to stop on a dime just because that 1/4" chain tells it to.
