Corn is America’s leading cereal crop and it is indeed necessary that there be adequate machinery for handling this crop. However, it is only by continuous efforts to insure good yields that modern corm machinery has been produced. Among these improved machines the corn planter is very important. To get the seed corn planted is of the greatest importance in securing a good crop. The corn grower must have equipment which is unexcelled to use for this operation. The modern farmer who is up-to-date assures himself that all seed corn used has a germination test of at least 98%. The present day farmer who is the successful corn grower is also just as particular about getting that seed into the ground. The corn planter must be mechanically accurate and serviceable.
