I just got my first implement (WoodMax Chipper) that uses the PTO. The implement manual says in at least two places to install the PTO with the shear bolt end attached to the tractor. The PTO shaft has a diagram printed on it that indicates the shear bolt end should be attached to the implement. I also watched one of Ted's videos (rotary mower) from Everyhing Attachments where he points out the shear bolt end attached to the implement.
So, which is it? Which end goes where and why?
