Even though this is my first plot , I can tell you all. The difference in a disc and a tiller is immense. We tried a 5 ft disc on that field that hadn't been touched in 20 years. It barely touched it. Rented the tiller for 125.00 for the weekend and had to go slow the first pass (@ 2 hrs for 2 acres) and got three total passes in 4 hours. Seed bed was 5 inches deep and very nice. The thatch you see in the pics is the old dead 4 inch fescue and other matter that was tilled up. Ill post pics in about another week. and Ill let you know on the beans. The farmer that owns the property say they will get a foot or so tall if frost or deer do not wipe them out.
