What is a Three Point Hitch and how does it work? I here you guys talk about the Classen Aerators and how good of a job they do but you need a Three Point Hitch. I am tired of getting pounded by using small walk behinds. I am looking to purchase a Aerator and really like the Ryan Lawnaire 28 but, have heard it does not do well on hills. Has anyone tried the new Classen Split-Drive? If so what do you think of it? I am guessing a three point hitch is only on tractors, maybe even powerd??? Could a three point hitch be put on a 4 wheeler? I can't justify buying a tractor so maaybe a 4 wheeler would work.
