Chisel plows pull hard. Any brand usually are good. 10-12 shanks is all you need usually 12 inch spacings. But will need duals on a 2wd or 4wd. Don't recommend any brand of disk except for the IH models 37, 370, & 470. They are the best made. Look for one in the 18-21foot range again will need 4wd or duals.
