A cultivator is a farm implement for stirring and pulverizing the soil,either before planting or to remove weeds and to aerate and loosen the soil after the crop has begun to grow. It is powered by a tractor and stirs the soil.usually to a greater depth than does the harrow (which is usually unpowered). Similar but much smaller machines are used for gardening.
