Machine for sowing cereals and other seeds, developed by Jethro Tull in England in 1701, although simple seeding devices were known in Babylon in 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.
