 By late 60's the government of India initiated the Green Revolution in India program and the need for mechanisation created more demands for farm tractors.To meet the initial demand the Government allowed lot of imports mostly from USSR and its Eastern Bloc neighbours.In addition six new manufacturers were established during this period although three companies (Kirloskar Tractors, Harsha Tractors and Pittie Tractors) did not survive.HMT, a large public sector unit, began manufacturing Agricultural Tractors in 1972 under the HMT brand name with technology acquired from Zetor of the Czech Republic.
