THE DESIGN AND FABRICATION OF MECHANCIAL LAWN MOWER

    Mechanical engineering department of the named institute has many non operational machines sequel to this fact maintenance which resulted to non development and non maintenance of the institute community at large.
    By this fact the project (mechanical lawn mower) was constructed and design to help in the development and maintenance of institution, community and the society at large in the area of grass cutting in our environment and the improvement in our food production and also the reduction of manpower.
    In other words, during the construction and design of this project many things were put into consideration such as our environmental condition, effectiveness of the machine and also maintenance were well observed and a minimized cost of maintenance and a highly successful repair was adopted and also the appropriate tools cost and quality of material were well consider.
