I have a 4 row no-till 7000 planter. There we two types of no till coulters offered for them, I actually have both types. One was a direct bolt to the row unit in front of the seed openers, and the other type was mounted to the upper row unit mounts and had its own down pressure springs just for the coulter. I have the first time on the 4 row 7000. I have the other type on my 5 row bean splitter that mounts behind it. I'll try and snap some photos for you and post them in the up coming days.
