Industrial Use
To the extent that cultivating is done commercially today (such as in truck farming), it is usually powered by tractors, especially row-crop tractors. Industrial cultivators can vary greatly in size and shape, from 10 feet (3 m) to 80 feet (24 m) wide. Many are equipped with hydraulic wings that fold up to make road travel easier and safer. Different types are used for preparation of fields before planting, and for the control of weeds between row crops. The cultivator may be an implement trailed after the tractor via a drawbar; mounted on the three-point hitch; or mounted on a frame beneath the tractor. They are driven by a power take-off shaft. Generally considered a secondary tillage implement, they are commonly used for primary tillage in lighter soils instead of plowing.
The largest versions are now available in a 6 m (20 ft) width, and require a tractor with an excess of 150 horsepower (110 kW) PTO to drive them.

Famous quotes containing the word industrial:
“Nearly all the Escapists in the long past have managed their own budget and their social relations so unsuccessfully that I wouldn’t want them for my landlords, or my bankers, or my neighbors. They were valuable, like powerful stimulants, only when they were left out of the social and industrial routine.”
—Willa Cather (1876–1947)
“The two most far-reaching critical theories at the beginning of the latest phase of industrial society were those of Marx and Freud. Marx showed the moving powers and the conflicts in the social-historical process. Freud aimed at the critical uncovering of the inner conflicts. Both worked for the liberation of man, even though Marx’s concept was more comprehensive and less time-bound than Freud’s.”
—Erich Fromm (1900–1980)
