Grain Drill

Once a field has been adequately leveled, and the sod has been broken into small enough pieces (or the rocks have been removed if the case may be), it is ready to be planted by the farmer. The type of implement that a farmer uses to plant the field depends directly on the type of crop he is going to plant. If the farmer has decided that he wishes to plant a grain of some sort on his land, the implement that he would choose is the grain drill. A grain drill has a series of individual round disk openers which carve out a small trench for the grain seed to be dropped into. As the wheels rotate, seed is augered from the seed hopper, through the seed tubes, and into the small trench. Round trace chains or spike-toothed drags follow the disk openers, fill in the small trenches, and bury the seed in the soil.
