The OP shows a Kubota B21 in his profile, this should work to power a 12v utility winch. The challenge is how to mount and utilize a winch to best serve the intended purpose. And it seems we are still not sure of the intended purpose. My understanding is that he has a smaller 20 ton splitter that he operates vertically. Therefore he does not have to lift the rounds only has to properly position them under the wedge on the small platform on the end of the vertical beam. I think he is looking for mechanical methods to move the rounds a few feet to the back of the splitter and into position on the small platform. My 20 year old nephew does that for me and all I do is operate the splitter while I sit on a larger unsplit round. When my nephew is not available, I have to bend over and roll the rounds to the splitter then manhandle them into the correct position for splitting. It would be great to have an easier or mechanical way to move and position the rounds.
