Design of Shoulder Strapped Grass Cutter

Abstract

Shoulder strapped grass cutting machine is being used in cutting grass, cleaning forest, gardening and maintenance of playground. Studies shows that during operating this machine the operator suffers a lot of pain in neck, shoulder, arm, wrist and fingers.Also the cutter blade is often damaged due to hindrance such as stones, bricks etc. coming in the path. Hence, we modified the design of the machine by replacing the shoulder strap by a push carrier to wear machine weight and reduce vibrations, adjust the height of cut for effective operation and ease of control. We also provided a casing to the blade for its protection from hindrances. Results after performance evaluation shows that the modification in machine was ergonomically acceptable and user friendly.
