Agricultural and forestry machinery. Safety requirements and testing for portable, hand-held, powered brush-cutters and grass-trimmers - Machines for use with back-pack power unit1 Scope This part of ISO 11806 gives safety requirements and measures for their verification for the design and construction of portable, hand held, powered brush cutters and grass trimmers with a back pack mounted combustion engine power source and mechanical power transmission between the power source and the cutting attachment. Methods for the elimination or reduction of hazards arising from the use of these machines and the type of information on
