Design of a Hand-held Grass Mower

The hand-held grass mowing machine is a petrolpowered machine with rotary blades for cutting grass on lawn. The machine was designed with locally available materials, putting into consideration factors such as strength, durability, light weight, ease of assembly and disassembling. This machine saves both energy and time, which is not so with the manual and pushable mowing methods, thereby providing greater and flexible mobility. A detailed design of the machine was done and performance test result shows that proper grass trimming is achieved in a comparatively shorter time with 67 percent process efficiency.
