The 21-inch steel deck cuts a wide swath, and integrated LED lights extend mowing hours into early morning or dusk.

What separates this mower is the 80V platform's sheer torque and the rapid charger that refills the 4.0Ah battery in 30 minutes. The mower folds vertically for compact garage storage, and the battery works with 75+ Greenworks yard tools. At 65 pounds, it's heavier than push models, but the self-propelled system makes it feel lighter than 40V competitors.

Buyer's Guide

What to Look for in a Cordless Lawn Mower

Battery Voltage & Runtime

Higher voltage equals more cutting power. 80V mowers handle thick grass like gas engines, while 20-24V models suit small, maintained lawns. Match runtime to your yard size—45 minutes covers ~5,000 sq ft.

Self-Propelled vs. Push

Self-propelled drives save effort on slopes and large lawns but add weight and cost. Push mowers are lighter, simpler, and ideal for flat, small properties where maneuverability matters more than muscle.

Cutting Width & Deck Size

13-16 inch decks navigate gates and tight spots; 17-21 inch decks finish large lawns faster. A 21-inch mower cuts 30% fewer passes than a 16-inch model, saving significant time on quarter-acre lots.

Height Adjustment Range

Look for 5-6 height positions from 1.5 to 4 inches. More settings let you scalp in spring, maintain summer height, and mulch leaves in fall. Single-lever adjustment beats adjusting each wheel individually.

Weight & Storage

Lightweight mowers under 40 pounds lift easily over curbs and store vertically. Heavier self-propelled models fold flat but need more garage space. Consider who will be mowing and your storage constraints.

Brand Ecosystem Compatibility

Sticking with one battery platform—Greenworks 40V/80V or MZK 40V—saves money on future tool purchases. A single battery that powers your mower, trimmer, and blower maximizes value and reduces clutter.

Our Testing Process

How We Test Lawn and Garden

⏱️
Runtime Trials
Mowed continuous 200-foot passes on standard turf until battery depletion, recording exact minutes and area covered per charge.
🌾
Dense Grass Performance
Tested each mower on 6-inch tall fescue and weedy patches to measure blade speed recovery and stalling resistance under load.
📐
Height Accuracy
Measured actual cut height versus dial settings at all positions to verify precision and consistency across the deck width.
📦
Maneuverability Course
Navigated obstacle courses with tight turns, tree rings, and gate widths to score handling and user fatigue over 30-minute sessions.
🔊
Sound Level Testing
Recorded decibel levels at operator ear position and property line to assess neighbor-friendly operation during early morning use.
🔋
Charge Speed Analysis
Timed full recharge cycles from empty and measured battery temperature to evaluate charger efficiency and long-term battery health.
Frequently Asked Questions

Lawn and Garden — FAQ

How long do cordless lawn mower batteries last?
Most lithium-ion batteries deliver 300-500 charge cycles, translating to 3-5 years of typical seasonal use. Store batteries indoors during winter and avoid complete discharge to maximize lifespan.
Can battery mowers cut thick or wet grass?
Higher voltage mowers (80V) handle thick grass reliably. Wet grass strains any mower and reduces runtime by 30-40%. Mow when turf is dry for best results and to avoid clumping.
Is self-propelled worth the extra cost?
Self-propelled justifies its price on slopes over 10 degrees or lawns exceeding 5,000 square feet. For flat, small yards, push mowers save money and weight without sacrificing cut quality.
How do I store a cordless mower in winter?
Remove the battery and store it at 50% charge in a climate-controlled space. Clean the deck, sharpen blades, and fold the mower vertically or cover it in an unheated shed.
What runtime do I need for my lawn size?
20 minutes covers 2,000 sq ft; 45 minutes handles 5,000 sq ft; 60+ minutes suits quarter-acre lots. Buy extra batteries if your property exceeds single-charge capacity.
Are cordless mowers lower maintenance than gas?
Yes—no oil changes, spark plugs, or fuel stabilizer needed. Just sharpen blades annually, clean the deck, and keep batteries charged. Brushless motors require zero maintenance.
Final Verdict

🏆 Bottom Line

The Greenworks 80V 21-inch self-propelled mower stands as the clear choice for homeowners wanting gas-like power without maintenance headaches, excelling on large, challenging lawns.

If your yard is under 3,000 square feet and flat, save money with the MZK 20V or STEELITE 21V compact mowers—they deliver clean cuts and easy storage without overpaying for unneeded voltage.
