I bought these drills several years ago and they had these manifolds on it when I got it. There's three ten foot sections of fertilizer manifolds and tubes. Could probably adapt to any box drill. They're set for 12" spacing but I bet you could add a couple more fittings to them for 10" pretty easily if you were putting them on different drills. They even have the orifices in them still. Could pull the opener tubes if you thought you could use them. Thought I would do something with them but just haven't done anything with it. Still on the drill, but was going to take them off. Thought I'd see if they were anything anyone could use before I junked them.
