ACKNOWLEDGEMENT

I take this opportunity to express my profound gratitude and deep to my mentor Mr.

Vinayak Hemadri for his exemplary guidance, monitoring and constant encouragement

throughout the course of this thesis. The blessing, help and guidance given by him time to

time shall carry me a long way on the journey of life in which I am about to embark. I also

take this opportunity to express a deep sense of gratitude to the mentor for his cordial

support, valuable information and guidance, which helped me in completing this task through

various stages.

Lastly, I thank almighty, my parents, and friends for their constant encouragement

without which this assignment would not be completed.

ABSTRACT

Rice is one of the chief grains in India, and as such, is a major food crop, especially in

the Eastern and Southern regions of India. Rice production accounts for a sizable amount of

the economy. However, farmers that lack resources continue to harvest the same using

traditional methods, which affect their yield, thereby affecting their earnings.

We propose to build a semi-automated paddy thresher that will help farmers improve

efficiency during threshing. It will also lower grain damage and reduce labor needed for

threshing. We also hope to lower power consumption and provide a mechanism for speed

control. We sincerely believe that the improved design can help enrich the lives of farmers

across the nation.
