Development of an Improved Solar Powered Lawnmower

Abstract

The need to develop, a user friendly, environment friendly, less noisy, less weighty lawnmower, led to this research on the development of a solar powered lawnmower. It was aimed at developing a solar powered lawnmower, which was achieved by designing, fabricating and testing the solar powered lawnmower system. The frame of the mower was made up of mild steel and the blade of the mower was made up of stainless steel, because of its strength and transmits a relatively high mass and speed form the motor. The motor used for transmitting enough speed to cut grass, was a 12V, 1hp, 3,500rev/min motor. Von-misses stress analysis was carried out on the blade to ascertain its strength during operation, using creo-parametric software. The performance evaluation on the machine showed that the mower battery lasted longer, charged fast, and had a low weight compared to the conventional ones.
