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.
Rotavator / Rotary Tiller
Advantages
» 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
