The gangs are adjustable on most discs. What type/brand of disc are you using? Pull behind? 3pt? Setting the discs as straight as possible is the least aggressive. I went with the straightest setting on my 3pt disc the last few years. It's not as hard on the equipment and I have mostly been using the disc just to rough up my clover and set the weeds back. Smooth blades or notched or both on the disc you have?
