How do the medium and large farmers obtain capital for farming? How is it different from the small farmers?

Large and medium farmers sell surplus farm products from a part of their produce. A part of the earnings is saved and kept for buying capital for the next season. A few of them give away the savings to small farmers and loans at high interest rates and get back the amount by the next season. Thus, they are able to arrange for the capital for farming from their own savings. Some farmers might also use the savings to buy cattle, trucks, or to set up shops.
