Design and simulation of a User-Friendly solar operated grass cutting device

Abstract

Conventional grass cutting devices are basically operated either by fuel or electrical energy. These are not environment-friendly and, furthermore, they demand high operational and maintenance costs. Encouraging the use of renewable energy resources is essential for sustainability. This paper proposes the design and fabrication of a solar operated lawn mower. Its blade cutting operation is based on the scotch yoke mechanism. The lawn mower components are presented. In addition, all necessary calculations of converting the solar energy into electrical energy are performed, as well as the calculations on the battery capacity needed and the time to charge. Moreover, structural analysis is done to check the strength of the developed frame and of the blades. The 3D CAD prototype is created, and the structural analysis of the lawn mower are performed by using SolidWorks© software. The design and calculations demonstrate that an efficient and sustainable solar operated lawn mower can be produced at minor costs.
