I believe this is all you will need to hook the tiller to your Gravely tractor. The bearing and u-joints all are good and smooth. The gear case turns smooth with no slop in the chain. Two tillers that I bought years ago, both turn smooth.What you see is what you get. I will not separate any parts from this set-up.
