This project emphasizes on minimization of harmful efforts of using the manual grass cutter. The new developed grass cutter is operated on the solar power and it consist of different parts likes Solar plate, Battery 12 Volt D.C., Wiper motor, Pedestal bearings, Rotar with blades and Grass cutter. In the new modified grass cutter the rotar is fixed between the two pedestal bearings is attached with the frame of grass cutter and wiper motor is attached to the rotar with universal coupling and wiper motor is fixed the grass cutter frame. Solar plate is fixed on the upper part of the grass cutter because of sun ray is directly on the solar plate and solar plate is directly connected to the wiper motor. Then start the rotating the motor is clockwise or anticlockwise depend upon the connection or as per our requirement. Now the project mainly concentrates on designing a suitable operating system. To maintain simplicity and economy in the design the locally fabricated unit has been used. Our project achieves higher safety, reduces human effort, increases the efficiency of the grass cutter, reduces the work load, reduces the fatigue of workers and reduces maintenance cost.
