  The gas-powered push lawn mower is an older mower type. Today there are many mowers that run solely on electricity and can be ridden, but gas-powered mowers are typically more powerful and can even cut wet grass. Push mowers are considered safest on changing terrain. When researching lawn mowers, consider your lawn's size, terrain, grass density and price range before purchasing one.
