</font><font color="blue" class="small">( In your photo what is the device on the pto shaft. Is it a thing like you use for a bushhog to let it freewheel. Also what should be the adjustment of the threaded shortarm link between the bracket mounted on the tractor and the tiller. thanks Paul )</font>
I have replaced that shaft with a new one since that picture was taken. The old shaft was a bit to short and when I tilled real deep it wanted to come apart on me. The yellow part you see in the picture is 1/2 of the protecive cover. If it was all there it would help keep you from getting wrapped up in the shaft should you have a momentary lapse in judgement and put you hand or arm near it. My new shaft has a protective cover on both ends.
