Gas Walk-Behind Mower: Why does my lawn mower cut unevenly?
If your lawn mower isn't cutting the grass evenly, first make sure that the wheels are set at the same height. If a wheel is damaged, replace it to ensure that the mower travels evenly over the lawn.
Also check that the blade is sharp and undamaged. A dull blade tatters rather than slices the ends of the grass, leaving the tips brown and dry. A damaged blade is off balance, so it cuts unevenly. Replace the blade if it's damaged.
