I think my 4-row 36" is a model 56. Excellent and trouble-free piece of machinery for a plate-type planter. Get the ground tilled well, and reasonably level, even if that means you have to disc at an angle. Experiment with the gear ratios and different plates to determine your actual seed rate. I've never tried to get 30,000 per acre with mine, but I'd bet it's possible. The best way to check it is to drop it into some sod in the barnlot that's been mowed really close. Then COUNT the number of seeds in a given length and use a calculator to get the approximate seed rate per acre. As mentioned in another post, don't push the speed too much, or you will get some erratic results. We pulled ours with a Farmall M in 4th gear at 3/4 throttle for best results, but with rain coming very soon, I planted corn once with the SM in 4th at full throttle, and it didn't do too badly! I've planted corn, soybeans, popcorn, sunflowers(special ring under plate), and garden seeds with mine. Not a modern planter, but a very dependable one!
