Whats the difference between a petrol mower and a rotary petrol mower?
A petrol mower is one that is fitted with a petrol engine, it can use several different methods to cut the grass. Alternatives are mains electric – with a long cable, and battery electric. Rotary mowers are usually the type that has a blade rotating on a vertical shaft. They cut the grass by the speed of the blade and can be used for quite long grass. The other type is usually called a cylinder mower. This has a horizontal shaft carrying twisted blades that cut in a scissor type action against a stationery blade. This type generally produces a finer finish.
