CSIR-CMERI developed a compact tractor for small farmers

CSIR-Central Mechanical Engineering Research Institute (CSIR-CMERI) has developed a compact, affordable and easily maneuverable tractor of low horsepower range to meet the requirement of the marginal and small farmers, with support from the SEED Division of DST.

A press release issued by Ministry of Science and Technology says they have promoted the technology among several existing SHG’s, and efforts were made to create new SHG's particularly for this technology. CSIR- CMERI is also discussing licensing it to local companies for large scale manufacturing, so that the benefits can reach the local farmers.

The tractor has been developed with a 9HP diesel engine with 8 forward and 2 reverse speeds, PTO with 6 splines @540 RPM. The total weight of the tractor is around 450 KG, having front and rear wheel sizes of 4.5-10 and 6-16 respectively. The wheelbase, ground clearance, and turning radius are 1200 mm, 255 mm, and 1.75 m respectively. It can help speed up farming, finishing it in a few hours in comparison to several days that the bullock cart needs and also reduces capital and maintenance cost of farmers. Hence, the affordable compact tractor could replace the bullock driven plough for small and marginal farmers.

The technology was demonstrated in nearby villages and to various manufacturers. A Ranchi based MSME has shown interest in manufacturing it by setting up a plant for mass production of the tractor. They plan to supply the developed tractor to farmers through different state government tenders at subsidized rates."

Marginal and small farmers comprise over 80 percent of cultivators in India. A large population of them still depend on bullock driven farming in which operational costs, maintenance costs and poor returns pose a challenge. Though power tillers are replacing bullock driven plough, they are cumbersome to operate. Tractors on the other hand are unsuitable for small farmers and unaffordable for most small farmers.
