A push mower, also known as a manual lawn mower, is a type of lawn mower that is pushed forward by the user. It is propelled by the physical effort of the person using it, rather than by an external power source. Push mowers are typically smaller and more lightweight than other types of lawn mowers, making them easier to maneuver around the lawn. They are also generally less expensive than self-propelled mowers.
A self-propelled lawn mower, on the other hand, is powered by an internal combustion engine or an electric motor and is capable of moving forward on its own. The user controls the speed and direction of the mower by a set of handles, and the mower moves forward under its own power. Self-propelled mowers are typically larger and heavier than push mowers, and they are more expensive as well. However, they are also easier to use, as the user does not have to exert as much physical effort to push the mower around the lawn.
In general, push mowers are best for small lawns with relatively flat terrain, while self-propelled mowers are better suited for larger lawns or yards with hills or uneven terrain. Both types of mowers have their own set of advantages and disadvantages, and the best choice for you will depend on your specific needs and preferences.
