Mechanization in 1801, displacing the centuries-old hand method of making individual sheets of paper. One of the first mechanical devices used in agriculture was the seed drill invented by Jethro Tull around 1700. The seed drill allowed more uniform spacing of seed and planting depth than hand methods, increasing yields and saving valuable seed. Mechanized agriculture greatly increased in the late eighteenth and early nineteenth centuries with horse drawn reapers and horse powered threshing machines. By the late nineteenth century steam power was applied to threshing and steam tractors appeared. Internal combustion began being used for tractors in the early twentieth
Seed drill the earth and the harrow would smooth the soil and break up any clumps. The drill would be set for the size of the seed used. Then the grain would be put in the hopper on top and then follow along behind it while the seed drill spaced and planted the seed. This system is still used today but it has been modified and updated so a farmer can plant many rows of seed at the same time. A seed drill can be pulled across the field using bullocks or a tractor. Seeds sown using a seed drill are distributed
