Weeding by hand is laborious and inefficient. Before the introduction of the seed drill, most seeds have been planted by hand broadcasting, an imprecise and wasteful course of with a poor distribution of seeds and low productivity. The seed is metered mechanically into an air stream created by a hydraulically powered onboard fan and conveyed initially to a distribution head which sub-divides the seeds into the pipes taking the seeds to the person colters. Most modern drills use air to convey seeds by plastic tubes from the seed hopper to the colters.
