The following specification particularly describes the invention and the manner in which it is to be performed
BACKGROUND
Field of Invention
[001] Embodiments of the present invention generally relate to an agricultural apparatus and particularly to a multipurpose tiller.
Description of Related Art
[002] In agriculture sector, elimination of plants such as weeds between and among row crops has been a major problem. In villages, a lot of manpower is required to eliminate the weeds from a crop field. Moreover, the elimination of the weeds consumes a lot of time and money. Further, there is a shortage of labors in the villages for eliminating the weeds. To reduce a need of a human intervention, tractors have been used by farmers to reduce an effort of eliminating the plants. However, the tractors are quite expensive and requires a lot of space. Moreover, a maintenance cost of the tractor involves a higher cost. Further, the tractors cannot be used in small areas, where the plants are planted in narrow rows.
[003] To overcome aforementioned problems, power tillers have been designed that helps the farmers in eliminating the plants in a faster and an easier way. However, the power tillers involve a higher initial cost and a high maintenance cost which is not affordable for the farmers having 2 to 3 acres of land. Moreover, various tilling equipment has been introduced such as, power tiller, a bull agro power tiller, and so forth. However, such trilling equipment perform only tilling operations, which makes the equipment less versatile. As in a rapid developing era, a farming industry requires the equipment or an apparatus which can perform multiple operations at a same time with less efforts.
[004] There is thus a need for an advanced and more-effective multipurpose mini tiller that can administer the drawbacks faced by the conventional approaches.
