A machine for sowing cereals and other seeds,
developed by Jethro Tull in England 1701,
although simple seeding devices were known in
Babylon 2000 BC. The seed is stored in a
hopper and delivered by tubes into furrows in
the ground. The furrows are made by a set of
blades, or coulters, attached to the front of
the drill. A harrow is drawn behind the drill
to cover up the seeds.
