Agricultural and forestry machinery. Safety requirements and testing for portable, hand-held, powered brush-cutters and grass-trimmers - Machines fitted with an integral combustion engine LONG_TITLE BS EN 3613 on normal1 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 (hereafter called machines) having an integral combustion engine as their power unit 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
