Here' s a picture of the disc I use.
I bought it used for $30 from an older gentleman who didn' t use it anymore. It was made to be pulled behind a small lawn/garden tractor. I had to modify it just a little to pull it behind an atv. The weights I used on it are large block off plates for pipe. It took roughly 3 hours to get it ready to go to work. It works great as long as the ground isn' t too dry. A medium to large sized tractor would be a lot better and faster but considering the extra cash they cost I' ll have to stick with my little disc until I win the lottery. I have pictures of some plots that I have disced with it. Go to my website below and click on the food plot pics button. Hope this helps.
