Buyer's Guide

What to Look for in a Cordless Lawn Mower

Battery Voltage & Runtime

Higher voltage equals more power. 80V tackles thick grass like gas, while 20-24V suits small, flat lawns. Runtime varies from 30-60 minutes per charge. Consider spare batteries for larger yards.

Cutting Deck Width

Wider decks finish faster but add weight. 21-inch cuts wide swaths for large lawns. 13-16 inch decks maneuver around obstacles and store easier. Match deck size to your yard's complexity.

Self-Propelled vs Push

Self-propelled drives the wheels, saving effort on slopes and large yards. Push mowers are lighter, cheaper, and better for flat, small lawns under 2,000 square feet. Test both if you have physical limitations.

Height Adjustment Positions

More positions equal finer control over cut length. Six positions handle varied grass types and seasons. Single-lever adjustment changes all wheels at once, while individual levers take longer but cost less.

Weight & Maneuverability

Lightweight mowers (30-40 lbs) are easy to lift and turn. Heavier models (60+ lbs) provide stability but fatigue users. Consider storage location and lawn obstacles when choosing weight class.

Tool Platform Compatibility

Greenworks 40V and 80V batteries work across 75+ tools, saving money long-term. MZK and STEELITE offer limited ecosystems. Buying into a platform reduces future battery costs for trimmers, blowers, and more.

Our Testing Process

How We Test Lawn and Garden

โฑ๏ธ
Runtime Test
Mowed identical 1,000 sq ft test plots repeatedly until batteries depleted, measuring actual minutes of cutting time across flat and sloped terrain.
๐Ÿ“
Slope Handling
Tested on 15-degree inclines to evaluate self-propelled systems and push mower stability, measuring wheel slip and user effort required.
๐ŸŒพ
Cutting Performance
Cut 6-inch tall fescue and thick Bermuda grass at various heights, measuring evenness, blade speed recovery, and mulching quality.
๐Ÿ”Š
Noise Level
Measured decibel levels at operator ear position and property line to ensure neighbor-friendly operation across all models.
๐Ÿ”ง
Assembly & Storage
Timed unboxing to first cut. Evaluated foldability, vertical storage capability, and garage footprint for each mower.
โšก
Battery Recharge
Drained batteries completely, then timed full recharge cycles. Tested rapid chargers against standard chargers where applicable.
Frequently Asked Questions

Lawn and Garden โ€” FAQ

How long do batteries last on a single charge?
Runtime ranges from 30-60 minutes depending on voltage and grass conditions. Our tests showed 80V systems average 45 minutes, while 20-24V units manage 30-35 minutes in normal cutting. Two-battery kits effectively double runtime.
Can cordless mowers handle thick or wet grass?
80V and 40V brushless models cut thick grass effectively, though wet grass challenges any mower. Lower voltage 20-24V units struggle with dense growth. Always cut more frequently during spring growth periods for best results.
What's the difference between self-propelled and push mowers?
Self-propelled mowers drive their own wheels, requiring minimal push effort on hills. Push mowers rely entirely on user force. Self-propelled adds cost and weight but saves energy on slopes over 10 degrees or lawns over 5,000 sq ft.
How much maintenance do cordless mowers require?
Virtually none. No oil changes, spark plugs, or air filters. Sharpen blades annually, clean the deck after use, and store batteries indoors during winter. Brushless motors are maintenance-free for the mower's lifespan.
Are cordless mowers worth it compared to gas models?
For yards under half-acre, absolutely. They're quieter, lighter, require no fuel storage, and start instantly. Gas still wins for massive lawns or commercial use. Battery technology now matches gas power for residential applications.
How should I store my cordless mower in winter?
Remove batteries and store them at 40-60% charge in a dry, room-temperature location. Clean the deck thoroughly. Store the mower itself in a shed or garage. Avoid leaving batteries in freezing conditions for extended periods.
Final Verdict

๐Ÿ† Bottom Line

The Greenworks 80V Self-Propelled mower is our top pick for its unmatched power and convenience on challenging terrain.

Upgrade if you have slopes or thick grass; choose the MZK 20V or STEELITE for flat, small yards under 2,000 square feet.
