A walk-behind lawnmower is designated into two categories, push and self-propelled. For a push, the operator pushes this mower around the yard to mow. For a self-propelled, the lawnmower is powered by a transmission, self-propelled walk behinds range from single-speed to variable speed models. 

Push mowers are best for smaller, flatter lawns. They are also popular with riding mower owners who need something smaller for trimming in tight areas or around landscaping. 

Self-propelled rotary mowers take the effort out of mowing thanks to a transmission that drives the mower forward. Single-speed and variable speed options have simple controls and are easy to use. Most self-propelled mowers offer 3-in-1 capability; they can be used for side discharge, bagging and mulching.

Residential walk-behind mowers, whether push or self-propelled, generally feature cutting widths of 19” to 30”.
