Fabbed this from those Agri Supply discs. Makes a nice furrow down either side of the row. Second shot is looking down a row of blackberries i just irrigated. I do my cultivating with an old Dearborn 13-2 spring shank, 2 row cultivator. You can see in the picture, does a pretty good job. I make the rows wide enough to drive my 8N down, drag the cultivator up and back every once in awhile. Don't have a picture of it, but it's the curved shank with sweeps on it instead of chisels. Took the shields off and spaced out the shanks to cultivate the full width of the tractor. HTH Mark
