Abstract
Weeding is one of the most labour-intensive operations in agriculture. Conventional manual methods are slow and costly, while chemical herbicides raise environmental concerns. A battery-driven motorized weeder offers a clean, efficient mechanical solution.
This project fabricates a lightweight agriculture weeder powered by a rechargeable battery and DC motors. Rotary blades or tines mounted on the chassis uproot or cut weeds between crop rows. Speed control and directional switches allow the operator to manoeuvre the machine safely in the field.
It is an excellent final-year project for Mechanical and Agricultural Engineering students, combining chassis design, power transmission and practical farm mechanisation.
