Petrol Lawnmower

A typical modern gasoline/petrol powered rotary "push mower" (or grass cutter) which has self-powered cutting blades, but still requires human power to move across the ground. "Walk-behind" mowers can be self-propelled, only requiring a human to walk behind and guide the mower.Most rotary lawn mowers are powered by an internal combustion engine, which runs on either two cycles or four. Two-cycle motors burn a mixture of gasoline and oil, while four-cycle motors burn gasoline and have a separate lubrication system.
