Kirk, here is a picture of one of my Cole mule drawn planters. Notice the mule hitch up front. This one bolts to my tool bar. This one has two seed cans(at the front) and one fertilizer can at the rear. One shift lever allows for one, both, or no seed drop from the seed cans. The other lever controls fertilizer. This "duplex" planter has the clockwise and counterclockwise seed plates. Seed plates sometimes come up on this site, Craigslist, and E-bay. You just have to keep looking because many of these planters are still used for food plots and deer plots.
