Tillage is the manipulation of the soil into a desired condition by mechanical means; tools are employed to achieve some desired effect (such as pulverization, cutting, or movement). Soil is tilled to change its structure, to kill weeds, and to manage crop residues.
Ferguson developed a hydraulically activated three-point hitch to which implements could be attached and which could lift and lower implements to the required working position. Ferguson also developed automatic control systems (draft, position) which greatly enhanced the performance of the equipment. Draft control is a system whereby the drawbar pull can be maintained at a constant level by automatically adjusting the position of the implement (e.g. plow) in response to variations in draft (e.g. soil resistance).
