Motorcycle Made to do Many things

Following is an extract/abstract from an article in Hindu dated February 11 2010. I got the link through my linkedin updates from Venkat.
Mr. Mansukhbhai Jagani an ordinary, not well educated farmer (a school dropout), in Mota Devaliya village, Amreli district, in Gujarat developed a machine system called Bullet Santi for small farm holdings, with attachments for tilling, sowing, inter-culturing and spraying. The motorcycle’s engine was converted to a 5.5 HP diesel engine and the rear wheel replaced with an attachment with two wheels.
Several farmers in the district have caught on to the idea, and there are now close to 40 Santis in the district. It costs between Rs. 14,000-18,000, making it much cheaper than other mechanical ploughs and it performs several functions such as weeding, ploughing and sowing for an acre. The bullet tractor ploughs an acre of land in just half an hour with only two litres of diesel.
With the help of National Innovation Foundation (NIF), Ahmedabad, Mr. Jagani got a patent in India and in the U.S. for this device. Mr. Jagani’s innovation was also displayed at the Indian Science Congress at Pune and at the Swadeshi Vigyan Mela at IIT, Delhi where he got an excellent response. He also got the opportunity to display his innovation in South Africa in an exhibition organized by the Department of Small, Medium & Micro Enterprises (SMME) of the Northern Provinces jointly with Commonwealth Science Council (CSC), London.
