My friend used his tractor with tiller to work the ground the first time. I then used my pull behind disc to till the ground several times before planting. My disc did break ground on a few small areas that the tractor did not till and woked great. I think that the notched front disc really help break the ground better than smooth ones. I add some weight to the disc when i want it to dig deeper. The other plot pic is my "foundation Mix" at 12 days growth. One of the brassica plots is in the background.Switchy those are awesome...did you use an ATV only the first time you cut the ground?
