Quick Verdict
The Greenworks 80V Self-Propelled Cordless Lawn Mower is one of the most capable cordless mowers we’ve tested for larger residential yards, with a wide 25-inch deck and dual battery ports that cut mowing time significantly. Its higher price and variable real-world runtime keep it from a perfect score, but for homeowners who want gas-style performance without the maintenance, it’s an easy recommendation. Rating: 4.5/5
Pros
- Wide 25" deck covers more ground per pass, ideal for lawns up to 3/4 acre, reducing total mowing time.
- Brushless motor provides high torque and longevity, with quiet operation (3x quieter than gas) that's neighbor-friendly.
- Self-propelled rear-wheel drive with variable speed control improves traction and reduces effort on slopes.
- Dual battery ports allow seamless switching between batteries, extending runtime without manual swaps.
- LED headlights enhance visibility for early morning or evening mowing, adding flexibility.
Cons
- Included 4.0Ah battery may not deliver the full 3/4 acre on thick or tall grass, potentially requiring a second battery.
- No bagging or mulching options mentioned; only side discharge, which may leave clippings on the lawn.
- Limited to battery runtime; for very large lawns, gas or corded electric might be more practical.
Bottom line: The Greenworks 80V 25" Self-Propelled Lawn Mower is a solid choice for homeowners with flat to moderately sloped yards up to 3/4 acre, offering a wide cut, brushless power, and self-propulsion. Its main limitation is the included 4.0Ah battery, which may not cover the full acreage under demanding conditions, and the lack of a bagging option.
Product position: This mower targets the mid-to-large suburban lawn segment where gas mowers dominate but buyers want the convenience of electric. With an 80V system and dual battery ports, it aims to deliver gas-like performance without the maintenance and emissions. The 25" deck is wider than typical 21" electric models, signaling a focus on efficiency.
Important features: The 25" steel deck reduces the number of passes needed, saving time. The brushless motor offers high torque and longer life, and it operates quietly, which is a plus in noise-sensitive neighborhoods. Self-propulsion with variable speed control helps on slopes and reduces operator fatigue. Dual battery ports allow you to insert two batteries and automatically switch to the second when the first depletes, extending runtime. LED headlights enable mowing in low light.
Limitations and alternatives: The supplied 4.0Ah battery may not deliver the claimed 3/4 acre if grass is thick or wet; you may need a second battery for larger jobs. This mower appears to lack a bagging option, meaning it only side discharges, which can leave clippings on the lawn and require raking. For those who need bagging or have very large yards, consider a gas mower or a model with bagging capability. If your lawn is under 1/4 acre, a smaller, less expensive electric mower might suffice.
Final verdict: The Greenworks 80V is a well-designed electric mower that offers strong value for its price, provided your lawn fits within its battery range and you can live without bagging. Before buying, measure your yard and consider grass conditions to ensure the battery will cover it, and check if additional batteries are affordable for your needs.
Strong Match: Homeowners with flat to moderately sloped lawns up to 3/4 acre who want a self-propelled electric mower with a wide deck to cut mowing time and avoid gas maintenance.
Also Consider It If: You value quiet operation for early morning or late evening mowing, or you have a larger property and are willing to invest in a second battery to extend runtime.
Not the Best Fit: If you need to bag clippings for a pristine lawn or have a very large yard (over 3/4 acre) that would require multiple battery swaps, this mower may not serve you well.
Decision in One Sentence: The Greenworks 80V 25" self-propelled mower is a great buy for medium-sized lawns where electric convenience and a wide cut are priorities, but check battery range and bagging needs first.
Consider It For:
- Wide 25" deck that cuts down mowing time on medium to large lawns.
- Brushless motor with quiet operation, ideal for noise-sensitive areas.
- Self-propelled rear-wheel drive with variable speed for easy handling on slopes.
- Dual battery ports for extended runtime without manual battery swapping.
- LED headlights for low-light mowing flexibility.
Pass If:
- You need a bagging option to collect clippings; this model only side discharges.
- Your lawn exceeds 3/4 acre or has thick, wet grass that drains the battery quickly.
- You prefer not to manage battery charging and want the unlimited runtime of a gas mower.

Performance & Build Quality
The 80V brushless motor is the heart of this mower, and it’s what separates it from lower-voltage cordless models. In thicker spring grass, it maintains blade speed without the bogging you’d feel on a 40V machine, producing clean cuts even on a single pass. It’s noticeably quieter than a gas mower, and there are no oil changes, spark plugs, or fuel stabilization to worry about — a genuine long-term maintenance advantage.
The 25-inch deck is a standout. Compared to the 20- or 21-inch decks on most residential mowers, it covers more ground per pass, which realistically shortens mowing time on a half-acre lot. The self-propelled rear-wheel drive with variable speed control performs well on slopes, where front-wheel-drive mowers tend to lose traction.
Two design features deserve special mention. The dual battery ports with automatic switchover mean the mower keeps running when the first battery drains — no mid-mow interruptions if you add a second battery. And the aluminum handles feel sturdier than the stamped steel found on entry-level electrics, contributing to a more premium overall build.
Real-world runtime is the honest caveat. Greenworks claims up to 3/4 acre on a full charge, and that figure holds on reasonably maintained lawns. But dense, tall, or damp grass — or hilly terrain — will cut runtime noticeably. The LED headlight is a practical touch for early morning or evening sessions, though it’s a convenience rather than a necessity.
Pros & Cons
- Powerful 80V brushless motor — strong torque and consistent cutting in thick grass
- Wide 25-inch deck — fewer passes and faster mowing than 21-inch models
- Self-propelled rear-wheel drive — excellent traction on slopes and uneven ground
- Dual battery ports — automatic switchover extends runtime without stopping
- Low maintenance and quiet — no gas, oil, or spark plug upkeep
- Premium build details — aluminum handles and LED headlights add long-term value
Flaws but not dealbreakers:
- Higher upfront price — at $599, it’s overkill for small, flat lawns
- Variable real-world runtime — thick, wet, or tall grass can fall well short of the 3/4-acre claim; a second battery may be needed
- Heavier and less nimble — the wide deck makes tight turns and storage more cumbersome than smaller mowers
Who Should Buy / Who Should Skip
Buy this mower if: you have a medium to large lawn (roughly 1/4 to 3/4 acre), deal with slopes or thick grass, and want to eliminate gas maintenance without sacrificing cutting power. The dual-battery design and wide deck make it especially suited to longer mowing sessions.
Skip this mower if: you have a small, flat yard under a quarter acre — a lighter, cheaper 40V model will do the job for less money. Also reconsider if you’re on a strict budget or lack storage space for a wider-deck machine.
Frequently Asked Questions
How long does the battery last on a single charge?
Greenworks claims up to 3/4 acre per charge with the included 4.0Ah battery. Real-world results depend on grass height, thickness, moisture, and terrain — dense or hilly lawns will drain it faster.
Do I need to buy a second battery?
Not necessarily. The dual battery ports with automatic switchover mean you can add a second battery to extend runtime, but many owners with well-maintained half-acre lawns finish on one charge.
Is this mower as powerful as a gas mower?
For most residential lawns, yes. The 80V brushless motor delivers torque comparable to many gas push mowers, and it maintains blade speed in thick grass. Extremely overgrown fields may still favor gas.
What maintenance does it require?
Very little compared to gas: no oil changes, spark plugs, or fuel treatment. Occasional blade sharpening, deck cleaning, and battery care are all it needs.
Is it good for hilly lawns?
Yes. The self-propelled rear-wheel drive provides better traction on slopes than front-wheel-drive designs, and the variable speed control lets you match pace to the terrain.
Is $599 worth it?
If you have a medium or large lawn and want gas-like performance with minimal upkeep, the time savings and reduced maintenance justify the price. For small yards, a less expensive model makes more sense.
