Garden maintenance, Hand- arm vibrations. Shrub trimming, Trimmers



Garden maintenance in public and private sectors involves day- by day care and endures great cost and labor. In addition to this the labors are subjected to Hand arm vibration (HAV) due to vibrating machines. HAVs cause musculoskeletal disorders, numbness and reduce hand grip strength. Noise induced hearing loss and ocular disorders are some of the issues associated with motorized vibrating garden trimmers. Hence it is necessary to design garden maintenance equipment by considering the problems associated with it. This paper proposes an optimized model of hedge trimmers capable of angle adjustment in blade projection. Furthermore, the paper investigates the performance of proposed trimming machine to conventional hedge trimmer in terms of uniformity in cutting, time taken for trimming operation, temperature of the equipment and vibration associated with it.
