A rotary tiller, also known as a rototiller, rotavator, rotary hoe, power tiller, or rotary plough (in US: plow), is a motorised cultivator that works the soil by means of rotating tines or blades. Rotary tillers are either self-propelled or drawn as an attachment behind either a two-wheel tractor or four-wheel tractor. For two-wheel tractors they are rigidly fixed and powered via couplings to the tractors’ transmission. For four-wheel tractors they are attached by means of a three-point hitch and driven by a power take-off PTO.
In some parts of the world, the term “power tiller” can encompass the larger and similar appearing two-wheeled tractor, a machine which does, however, operate different attachments; in most English-speaking regions this difference is considered more rigid, as the term power tiller (and this article) refers solely to devices with soil cultivation as their primary and often only function.
» It cuts soil deeper and allows greater soil rotation, whether dry or wet soil, which improves organic structure of the soil.
» It is Suitable for slashing thick and fibrous residuals of crops such as sugarcane, banana, cotton etc. It also mixes them in the soil very well to increase fertility of the soil.
» Its increased thickness of the blades augments lifespan of the blades as well as reduces the cost of rotovation per hectare.
» It can till larger portion of land in comparatively lesser time which would result into savings in diesel
