We had 2 of them in the sixties that we eventually built a toolbar and made a four-row mounted planter out of them. You can aquire plastic 24 cell plates to put in inplace of the steel plates, if that's what is in the planter now. They are fairly accurate and stay in the ground well, but the runner-type opener is best used in conventionally tilled soil, meaning plowed with a bottom plow or rototilled. They will not work well at all with surface trash where the ground was chisel plowed or if you are trying to no-til. The fertilizer attachments were notorious for rusting out, even with end-of-planting cleanout with water and compressed air and applying diesel fuel or light oil to the inside. We solved that problem by switching to liquid fertilizer with saddle tanks on the tractor. We got plastic plates at the A-C dealer and seed dealers and amassed quite a collection, as I upgraded to the #71 disc opener unit on a no-til frame and did much custom work over the next 16 or so years. The #71 unit was similiar to these old units, but were the disc opener type. We were able to plant at about 3.5 MPH with that old planter and get a good consistent seeddrop. I see yours has already been converted to 3 point hitch. They were originally snap-coupler. If you were fortunate enough to get the owner's manual, it will tell you the different sprocket settings to determine planting population and fert. amounts per acre. They are a nice, simple planter to maintain and operate. Looks like you got one in excellent shape!
