Why you should trust this review
We tested five cordless push mowers over a full mowing season on flat and gently rolling quarter-acre lawns in fescue and Bermuda grass. We measured blade tip speed with a contact tachometer, recorded cut uniformity with a 10-point photo scoring system, and timed battery depletion at three growth heights. Three testers of different heights and strengths rated maneuverability and handle ergonomics.
How we tested cordless electric push mowers
Standardized test: mow a flat 8,000 square foot fescue lawn at 3-inch height with a full battery. Record time to complete, battery remaining, and rate cut quality on 10-point scale. Repeat at 2.5 inches. Measure time for blade to stop after trigger release. Weigh mower on certified postal scale for verified weight comparison.
Who should buy a cordless electric push mower?
Push mowers are the right choice for flat lots up to a quarter acre, budget-conscious buyers who want cordless convenience without the self-propelled premium, and physically active homeowners who prefer the workout of pushing. They are also lighter for transport and storage, which matters if your lawn mower lives in a basement, garage, or truck bed.
Ryobi RY401150 40V HP: brushless efficiency at a real-world price
The Ryobi 40V HP mower with brushless motor was the best all-around push mower in our test. The brushless motor produced 15% higher blade tip speed than the brushed competitors, resulting in cleaner cuts at lower heights and more effective mulching. The single-point height adjustment — one lever moves all four wheels simultaneously — is a quality-of-life feature that costs nothing but makes height changes effortless. The steel deck held up to rocks and curb contact without damage during the season.
Runtime on the 5Ah battery covered our entire 8,000 sq ft test lawn at 3 inches with 25% remaining. At 2.5 inches, the draw is higher and finished with 15% remaining — still enough for touch-ups.
Greenworks 40V 20-inch: best for Greenworks platform users
The Greenworks push mower delivers comparable cut quality to the Ryobi with a reliable brushless motor. It is slightly heavier at 53 lbs but has a wider handle that some testers found more comfortable. The 40V platform compatibility with Greenworks string trimmers and blowers makes it a strong choice for users building out a full Greenworks system. The 20-inch deck, mulch, bag, and rear discharge options all included in the box represent solid value.
What to look for in a cordless electric push mower
Brushless motor: Always choose brushless over brushed for efficiency, longevity, and sustained blade speed under load. The premium is minimal at this price tier.
Deck material: Steel decks resist dents and last longer. Plastic decks are lighter but dent from rock strikes. For most home use, either works, but steel is the premium choice.
Weight: Under 55 lbs for a 20-inch push mower is the target. Every pound over that is felt on slopes and when maneuvering around obstacles.
Single-lever height adjustment: A feature found on better models but absent on budget ones. Worth prioritizing because you will use it every time you mow.
Battery platform: Matching your push mower battery to other cordless tools means you can interchange batteries when a tool runs low mid-job.
Frequently asked questions
Is a push cordless mower suitable for a quarter-acre lawn?+
Yes for flat terrain. A 20-inch deck covers 5,000 square feet in about 30-35 passes and typically uses 60-70% of a 4Ah battery, leaving enough for a second partial run.
How much lighter is a push mower versus self-propelled?+
Push mowers are typically 10-15 lbs lighter, which matters when lifting it over curbs, into the truck, or up steps to a storage area.
Do cordless push mowers require any maintenance?+
Minimal compared to gas. Keep the underside of the deck clean after each use, sharpen or replace the blade annually, and store the battery at partial charge during winter.
Can I use any 40V battery in a Ryobi 40V push mower?+
Yes, any Ryobi 40V ONE+ battery is compatible regardless of Ah rating. Higher Ah batteries extend runtime proportionally.
