Ergonomic diagnosis of harnesses used in gasoline brush cutters: parameters for the design of comfortable accessories

Abstract

Motorized manual equipment is increasingly present in everyday tasks. Projects that are not focused on ergonomic attributes plus the misuse of those tools can lead to musculoskeletal disorders. The present study carried out an analysis of the incidence of discomfort caused by harnesses in activities with gasoline brush cutters. Through a field survey, 10 potential users performed the mowing activity by experimenting 5 different harnesses, one of them was designed with ergonomic attributes. The results showed that the harness with ergonomic qualities presented lower complaints of discomfort during the activity.
