I am looking to purchase my first plow and I am trying to find which one is best. I have found an all purpose plow that is a 5 shank all purpose plow. It resembles a box blade just with out the box. Then at tsc i saw a sub soiler, middle buster and a cultivator. This fresh ground that was once wooded so I am dealing with roots. The sub soiler doesnt seem to be for me. The cultivator seems like I will be breaking and bending teeth for the initial plow. I am torn between the all purpose and the middle buster. The middle buster is about a 100 bucks cheaper but I'm not sure what how it will do with roots
