The draft protocol establishes the safety certification procedure for electric pedestrian-controlled walk-behind cylinder and rotary lawnmowers, designed mainly for household use or similar purposes, with a single-phase electric motor with a voltage not exceeding 250 V, equipped with metallic cutting means and/or non-metallic cutting means and/or non-metallic cutting means with one or more cutting elements pivotally mounted on a generally circular drive unit, where these cutting elements rely on centrifugal force to achieve cutting, and have a kinetic energy for each single cutting element of greater than 10 J.
