I have a John Deere No.4 log splitter mounted on a 1968 JD 110 Garden tractor. The tractor runs the splitter with a pulley system off the PTO. The splitter has the owners manual and can be used on any 100, 200, 300, or 400 series tractors. I am wanting to sell it and have no idea what its worth...I cannot find any on ebay or anywhere to get a value. It works great! Any help would be great!!
