Ten Best Quiet Lawn Mowers In 2021 + Mini Buyers Guide

Whether you’re a professional landscaper or a homeowner who wants to keep their lawn, garden, or other green space looking trim and neat, there are a number of exciting new breakthroughs in lawn mowing technology that are transforming the experience by drastically reducing the amount of noise produced when operating a lawnmower. Instead of creating a disturbance that could potentially disrupt neighbors, members of the household, or the general public, today’s new quiet lawnmowers allow users to quickly and efficiently cut and trim grass without producing a lot of noise.

A Mini Buyers Guide for Choosing the Right Quiet Lawnmower

Before choosing the right quiet lawnmower for you, it is important to assess how you will plan on using your new lawnmower. For smaller yards that will be frequently mown, a more narrow, hand-powered model could be the ideal lawnmower for your needs. For larger yards and more substantive landscaping needs, a lawnmower with a bigger deck (a wider cutting swathe) and a more powerful motor could be a worthwhile investment.

Today’s quieter lawnmowers come in three basic types:


Human Powered

Human-powered lawnmowers have been around for more than a century, but many of the older designs suffered from an inability to handle thicker clumps of grass, taller grass, and debris with ease. Today’s new human-powered models take advantage of engineering breakthroughs to ensure that the lawnmower is easy to operate, tough enough to handle more challenging areas of grass and debris, and come with a variety of useful attachments, including grass catchers. Human-powered lawnmowers are not just virtually silent when in use but come with the added advantage of being a sustainable and environmentally-friendly way to perform basic lawn and garden care.


Electric Motor

The first electric lawnmowers relied on lengthy cords to operate, making it difficult and cumbersome to perform large trim jobs or do quick clean-ups on trouble spots in your yard. Today’s advanced electric lawnmowers have been engineered to be incredibly quiet when in use, and many come with powerful, rechargeable batteries so that no lengthy extension cords are needed. Electric lawnmowers not only operate far more quietly than traditional gas-powered motors, they provide for a more pleasant cutting experience as there are never any messy, explosive, and stinky fuels to deal with.


Gasoline Motor

Although no gas-powered lawnmower can hope to operate as silently as a human-powered lawnmower, some of today’s leading lawn and garden equipment manufacturers have revolutionized the design of their lawnmowers in order to combine the power and reach of a gas-powered mower with new breakthroughs in sound reduction technology.
