I am making a new food plot and I am looking at two different disc tillers to buy. One is the Groundhog Max that you hook to your hitch and the down force of your ATV puts weight on the plowing discs and the other is the King Kutter 8 disc pull behind disc harrow. Does anyone know anything about these two items and how well they work? I am worried that the down force on the Groundhog will put too much weight on my hitch and cause wear on my ATV, but it looks so much easier than using the King Kutter.
