With the cylinder design, you can get electric lawnmowers, petrol-powered ones or simple hand-pushed models. The blades rotate vertically like a cylinder against a bottom blade and this gives a scissor-like cut for a well-manicured lawn. Cylinder mowers are perfect for level lawns where you're after a really fine, short cut. They come with a variety of cutting widths, rollers for a striped effect and a detachable grass collection box
