Just a heads up for you guys without a tractor but have an atv. A good option for a disc, if it is your only option, is acme rents has the antler king sodbuster disk that you can rent. I think it is like $70 a day or something. Last year after I had burnt down some crp with powermax and another desiccant mixed together I went in with that and on the first pass it was down 4-5", and with every pass after that it became a little deeper and a little more mellow. I used a 650 fourwheeler in low and it pulled hard but got the job done.
