Looking for info on my Oliver planter. I planter corn this year but it looks terrible. I used the same plates the previous owner said he used but clearly didn't work out so well for me. These are the plates I have and looking for help with what plates go for what seed. I have 4 plates numbered 245537b, 4 plates numbered 245531b, 4 plates numbered 245510b, 4 plates numbered 245511b, 4 plates numbered 245506b, 4 plates numbered 245500b, 1 plate numbered 245533b, 1 plate numbered 245501b. Any help would be greatly appreciated.
