How was the advent of new technology helpful to the farmers?

The dramatic expansion of agriculture was made possible by new technology. Through the nineteenth century, as the settlers moved into new habitats and new lands, they modified their implements to meet their requirements. When they entered the mid-western prairie, the simple ploughs the farmers had used in the eastern coastal areas of the USA proved ineffective. The prairie was covered with a thick mat of grass with tough roots. To break the sod and turn the soil over, a variety of new ploughs were devised locally, some of them 12 feet long. Their front rested on small wheels and they were hitched on to six yokes of oxen or horses. By the early twentieth century, farmers in the Great Plains were breaking the ground with tractors and disk ploughs, clearing vast stretches for wheat cultivation.Once the crop had ripened it had to be harvested. Before the 1830s, the grain used to be harvested with a cradle or sickle. At harvest time, hundreds of men and women could be seen in the fields cutting the crop. In1831, Cyrus McCormick invented the first mechanical reaper which could cut in one day as much as five men could cut with cradles and 16 men with sickles. By the early twentieth century, most farmers were using combined harvesters to cut grain. With one of these machines, 500 acres of wheat could be harvested in two weeks. For the big farmers of the Great Plains these machines had many attractions. The prices of wheat were high and the demand seemed limitless. The new machines allowed these big farmers to rapidly clear large tracts, break up the soil, remove the grass and prepare the ground for cultivation. The work could be done quickly and with a minimal number of hands. With power-driven machinery, four men could plough, seed and harvest 2, 000 to 4, 000 acres of wheat in a season.
