A push mower is a type of lawn mower that requires the user to manually push it across the grass. It typically features a rotating blade that cuts the grass as the mower is moved forward. Push mowers can be powered by gas, electricity, or are even available in a manual reel version, which uses a set of blades that spin as the mower is pushed. These mowers are popular for small to medium-sized lawns due to their ease of use and lower environmental impact compared to riding mowers. They are also generally more affordable and require less maintenance, making them a practical choice for many homeowners.
