The Context

Mechanization of agriculture is critical to
enhancing the agricultural production to feed
an ever-increasing global population. Apart
from the cost of buying an expensive piece of
equipment like a tractor, the rising cost of diesel
fuel also significantly impacts the affordability of
tractors, especially in less-developed countries.
This has led to a low permeation of tractors
in the farming sector of developing countries.
For instance, in India only 5% of agricultural
households own a tractor. Tractor demand is
expected to go up due to shortage and rising
costs of farm labour. Development alternatives
that aid in the transition from diesel to power
tractors is the need of the hour.

The Context

The project has developed Solectrac - a Solar Electric
Tractor that is a fully functional agricultural tractor operating
with up to five times the efficiency of a diesel version
performing the same farming tasks. Solectrac with a battery
inverter system provides electric power anywhere, anytime.
It can also be used for portable power, water pumping and
mechanical functions as well as hauling and transportation
needs. Since the Solectrac is electric, its batteries can be
charged directly by renewable energy or it can be charged
at a low cost from the electric utility grid at off-peak rates.
Solectrac uses patented “quick change” battery packs to
extend operational periods. A striking technical feature here
is the special transmission system made specifically for
electric tractors wherein it takes power from the batteries
instead of the PTO (Power Take Off) Shaft as in the case of
conventional tractors. Yet another novelty is the “Mid Hitch”
which allows for clear visibility and hence better control of
the implements attached in front of the tractor, a feature not
seen in traditional diesel driven tractors.

The Outcome

The team has completed the development of Pre-Production Prototype and implements. The
Computer Aid Design (CAD) drawings are also complete. The Final Production Prototype and
complete testing for commercial production is presently under progress.
