The  headpiece  is  supported on the  soil  by two boat- shaped floats whereby the ends of the tubes are held about three inches from the soil surface. The  handle  for  drawing the  Implement  emanates  from  the  headpiece. The  Implement  is operated by two persons-One draws the implement while the, other follows to feed the, seed through the seed bowl. The seed regulation depends on both operators.

1.1 Introduction Seeds come in an immense variety of shapes and sizes. Small grains include wheat and rice as well as small and slippery oilseeds such as flax and canola. Large seeds include grain corn with seed on ears, soybeans, and other beans in pods. Plant height varies from ground-hugging peas to elevated ears on tall cornstalks. Such wide variations create unique demands for harvesting machinery. All these crops from oilseeds, grass, and clover seeds through to large fava beans are mechanically harvested with combines and mechanical threshers. The term “grain” will be used here to include all types of seeds. 1.2 History Until the nineteenth century, most grain was harvested by cutting with a sickle or scythe, then manually flailed or beaten to break the bond of the grain with the stalk, then winnowed to separate the grain from material other than grain (MOG). In the developing world, these practices or the use of small stationary threshers are still in use for rice...
