It does not apply to: robotic and remote-controlled lawnmowers, flail mowers, grassland mowers, sickle bar mowers, towed/semi-mounted grass cutting machines, and scrub-clearing machines; cutting-means assembly when used in combination with an agricultural tractor; electrically powered and battery-powered lawnmowers.
