Kubota B5100 front differential problem

Thanks Brian. That makes good sense. Appreciate the help.

Update: This weekend I bolted up the front end and drained the oil from the front diff. There was almost no oil inside, and a few shards of metal came out. I refilled it and tried it, just to be sure, and the problem is still very much there. Probably a ring gear. So much for borrowing the neighbour's tractor to save myself some work. I'll see what he has to say. Thanks again everyone for your help on this.

Hey again, it turns out the ring gear stripped. There was hardly any oil in the front differential, and when I split it open the problem was obvious. The pinion is scarred but usable, but the ring gear is shot. Kubota up here in Canada doesn't list parts for that era of tractor. Thoughts on where to look?
