If you’re looking for a used John Deere air seeder for sale, you’ve come to the right place. You can find a 1991 or a 1990 air seeder for sale online. Both of these machines have the same basic design, but are made with different features. If you’re interested in an old air seeder, look for a John Deere Central Commodity System (CCS) model. This model has the same drive system as the current one, but is not the same as the newest model.
