I just bought a couple old cole planters from an auction this weekend. One is mounted on an a 3 pt. A frame cultivator. The cultivator and the planter both have Cole decals on them, and the cultivator frame looks to be originally painted white and the planter green. It came with a 32 hole pea and soybean plate and a 8 hole hybrid corn flat. My question is the corn plate that I have the correct one for planting sweet corn? The other planter I bought is a double seed hopper style that looks like it will mount to the A frame cult. the same as the one thats on it already. It has two 6 hole corn plates in it. Its missing its lid but seems to turn good. Questions about this one is, whats the deal with having two hoppers? Is one planter better that the other? Can you still buy odd parts like the lids and decals for these planters? Thanks
