Also called a seeder. In addition to the simple hand-pushed seeder that mechanically pushes the seeds through holes in a seed box, there are also spot seeders, row seeders, and broadcast seeders that are pulled by a tractor. Spot seeders and row seeders are designed to drop the seeds from a delivery device located under the hopper, and are usually equipped with a furrow cutting device and a soil covering device. Broadcast seeders spread the seeds from a centrifugal spreader with blades, and many can also be used as fertilizer applicators. → Related items Agricultural machinery Source : Heibonsha Encyclopedia About MyPedia Information |
