CHAPTER XXXIV SEEDERS AND DRILLS Utility of Seeders and Drills. The seeder should be used only where the drill is impractical, as it is not a machine adapted to the most improved methods of farming. The drill enables all the seed to be covered at a uniform depth and to be very uniformly distributed. The broadcast seeder may distribute the seed uniformly, but the harrow or other implement which follows it will not cover the seed at a uni- form depth, meaning that a part of the seed is placed too deep and a part too shallow. The saving of seed alone in sowing a large field is often sufficient to practically pay for a drill. There are certain seeds, however, that must be covered very shallow, and the modern drill is not well adapted for the purpose. At one time grass seed was broadcasted on meadows to thicken the stand, but the drill has been found to do this work more satisfactorily. SEEDERS Hand seeders are used on rough ground where horse machines can not be used. A very satisfactory type is the crank machine with a whirling distributor. It is not possible to secure a very even seeding in this way, but that is often quite unavoidable. This type of machine should have an agitator for feeding the grain to the distributor. No attempt should be made to use the machine on a windy Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Davidson, Jay Brownlee, 1880-1957.
