Development of a prototype mechanical one-handed grass clipping cleaner / Syakirah Aqilah Syahril Mukhzani

This study examines the role of single-handed mechanical grass clipping cleaner as farmers need an easier way to clean grass clipping after the grass is cut. Using traditional rakes is not effective as it consumes time and energy to clean a larger field. Moreover, when using the blower, it required fuel to power up the blower motor. This method is high cost and not environmentally friendly as the blower will exhaust harmful gases. The objective of this project is to design a single-handed mechanical grass clipping cleaning device that can be operated by a single person by benchmarking and comparing the design with related available products in the market. An analysis is made to the finalised design on the rotating element part to study the maximum stress that can be withstand by it while the mechanical grass clipping cleaner is operating. Moreover, to fabricate single handed mechanical grass clipping cleaner that is only powered by power transmission mechanism. In conclusion, the prototype is fabricated, and it works when the rotating element rotates to collect the grass clipping into the collecting bin. The rotating element is rotated by the power that is transmitted by the sprocket and chain from the back tire. Result shows grass clippings are collected inside the bin effortlessly without producing any sound and harmful emissions
