A\u00a0cultivator<\/b>\u00a0is a piece of\u00a0agricultural equipment<\/a>\u00a0used for secondary\u00a0tillage<\/a>. One sense of the name refers to frames with\u00a0teeth<\/i>\u00a0(also called\u00a0shanks<\/i>) that pierce the soil as they are dragged through it\u00a0linearly<\/a>. It also refers to machines that use\u00a0rotary motion<\/a>\u00a0of disks or teeth to accomplish a similar result. The\u00a0rotary tiller<\/b>\u00a0is a principal example.<\/p>\n

Cultivators stir and pulverize the soil, either before planting (to\u00a0aerate<\/a>\u00a0the soil and prepare a smooth, loose\u00a0seedbed<\/a>) or after the crop has begun growing (to kill\u00a0weeds<\/a>\u2014controlled disturbance of the\u00a0topsoil<\/a>\u00a0close to the crop plants kills the surrounding weeds by uprooting them, burying their leaves to disrupt their\u00a0photosynthesis<\/a>, or a combination of both). Unlike a\u00a0harrow<\/a>, which disturbs the entire surface of the soil, cultivators are designed to disturb the soil in careful patterns, sparing the crop plants but disrupting the weeds.<\/p>\n

Cultivators of the toothed type are often similar in form to\u00a0chisel plows<\/a>, but their goals are different. Cultivator teeth work near the surface, usually for\u00a0weed control<\/a>, whereas chisel plow shanks work deep beneath the surface, breaking up\u00a0hardpan<\/a>. Consequently, cultivating also takes much less power per shank than chisel plowing.<\/p>\n

Small toothed cultivators pushed or pulled by a single person are used as\u00a0garden tools<\/a>\u00a0for small-scale gardening, such as for the household's own use or for small\u00a0market gardens<\/a>. Similarly sized rotary tillers combine the functions of harrow and cultivator into one multipurpose machine.<\/p>\n

Cultivators are usually either self-propelled or drawn as an attachment behind either a\u00a0two-wheel tractor<\/a>\u00a0or four-wheel\u00a0tractor<\/a>. For two-wheel tractors, they are usually rigidly fixed and powered via couplings to the tractors' transmission. For four-wheel tractors they are usually attached by means of a\u00a0three-point hitch<\/a>\u00a0and driven by a\u00a0power take-off<\/a>\u00a0(PTO).\u00a0Drawbar<\/a>\u00a0hookup is also still commonly used worldwide.\u00a0Draft-animal<\/a>\u00a0power is sometimes still used today, being somewhat common in developing nations although rare in more industrialized economies.<\/p>\n
