Greenworks Mowers Reviews: The Ultimate Voltage Guide
From the lightweight 40V agile push mowers to the beastly Pro 80V series, we break down which Greenworks electric mower is the perfect match for your lawn.
Top Pick : Greenworks Pro 80V 21-Inch
Check Price on AmazonIntroduction: Why Choose Greenworks?
If you have been following our coverage of electric lawn mower reviews, you know the market is crowded. Yet, Greenworks remains a dominant force. Why? Because they aren’t just a mower company; they are a battery company.
Unlike traditional gas manufacturers who are clumsily pivoting to electric, Greenworks started with batteries. Their ecosystem is massive. The same battery that powers your mower can run your leaf blower, edger, and even your snow thrower. This interoperability saves you money and garage space.
However, their lineup can be confusing. With 24V, 40V, 48V (2x24V), 60V, and 80V options, how do you know which one handles thick grass and which one is just a toy? In this comprehensive review, we categorize their machines to help you stop guessing and start mowing.
Decoding the Voltage: 40V vs. 60V vs. 80V
Before we dive into specific models, you need to understand the “Power Hierarchy.” Voltage essentially equates to the “horsepower” of the unit.
- 40V G-MAX System: Designed for small to medium yards (up to 1/3 acre). These are lightweight, often have plastic decks, and are very quiet. Great for maintaining a tidy, flat lawn.
- 60V Pro System: The “Sweet Spot.” These often feature steel decks and brushless motors. They compete directly with the power of gas mowers but maintain the agility of electric tools. Perfect for 1/2 acre lots.
- 80V Pro System: The Beast. If you have thick St. Augustine grass, uneven terrain, or a property up to 1 acre, this is what you want. It delivers torque comparable to a 160cc gas engine.
1. Greenworks Pro 80V 21-Inch Self-Propelled Mower
Best For: Large Lawns & Thick Grass
This is the flagship. The Greenworks Pro 80V is widely regarded as one of the few electric mowers that can truly replace a gas unit without compromise. It features a durable 21-inch steel deck and runs on a brushless motor that detects grass density.
Performance: In our tests, the “SmartCut” technology is a game-changer. When you hit a patch of overgrown grass or weeds, the motor audibly revs up, powering the blade through without stalling. It mulches exceptionally well, returning nutrients to the soil (see our guide on lawn fertilizing naturally).
The Catch: It is heavy. The steel deck and large battery make it feel like a tank. However, the rear-wheel-drive self-propel system mitigates this significantly.

2. Greenworks 60V 21-Inch Mower
Best For: The Average Suburban Home
If the 80V is overkill and the 40V feels like a toy, the 60V Pro is just right. It shares the durable steel deck DNA of its big brother but sheds some weight. For most homeowners with a quarter-acre to half-acre lot, this is the sweet spot of performance and price.
It usually comes with a 5.0Ah battery, which provides about 45 minutes of run time. If you own other 60V tools like the best lawn trimmers from Greenworks, swapping batteries is a breeze. The cut quality is crisp, provided you keep your blade sharp (learn how here).
3. Greenworks 40V 20-Inch Twin Force
Best For: Small Yards & Budget Buyers
This model is a legend in the electric mower world. The 40V Twin Force uses two blades (dual blades) to create a fine mulch. Unlike the single-blade monsters above, this unit utilizes a composite (plastic) deck. While that sounds cheap, it has a massive advantage: it never rusts and is incredibly light.
The “Twin Force” refers to the dual battery ports. While it doesn’t draw from both simultaneously, it allows you to carry a spare on board. When one dies, you switch over. It is perfect for flat lawns where maneuverability is key. However, don’t expect it to plow through a jungle; if you have neglected your lawn maintenance for weeks, this mower might struggle.
Alternatives: When Greenworks Isn’t the Answer
While we love Greenworks, they aren’t the only game in town. If you are looking for specific features, consider these alternatives:
- For Automation: Why push a mower at all? The Mammotion Luba 2 and Sunseeker Orion X7 are robotic mowers that handle slopes and complex yards without perimeter wires.
- For Striping: If you want those professional baseball field stripes, the Segway Navimow offers precision GPS cutting that is hard to beat manually.
- For Commercial Use: If you run a business, you might want to look at Kress Robotic Mowers or commercial-grade electric stand-ons.
Quick Comparison: 40V vs 60V vs 80V
| Feature | 40V System | 60V System | 80V Pro System |
|---|---|---|---|
| Ideal Yard Size | Up to 1/3 Acre | Up to 1/2 Acre | Up to 1 Acre |
| Deck Material | Mostly Composite | Steel | Heavy-Duty Steel |
| Engine Equivalent | ~140cc Gas | ~150cc Gas | ~160cc-170cc Gas |
| Tool Compatibility | 75+ Tools | 50+ Tools | 75+ Tools |
| Weight | Lightweight | Moderate | Heavy |
Maintenance Tips for Your Greenworks Mower
Electric mowers are “low maintenance,” not “no maintenance.” To get the best cut:
- Sharpen the Blade: A dull blade tears grass, leading to a brown haze and susceptibility to lawn pests and diseases like brown patch fungus.
- Clean the Deck: Use a plastic putty knife to scrape wet grass from the underside. This ensures proper airflow for mulching.
- Store Batteries Indoors: Extreme heat and freezing cold kill lithium-ion cells. Store your batteries in a climate-controlled area, especially when preparing your lawn for winter.
- Check the Bag: If you bag clippings, ensure the mesh isn’t clogged with dust. A clogged bag prevents suction.
Frequently Asked Questions
Are Greenworks mowers worth the money?
Yes, they are widely considered the value leaders in the electric space. They offer performance close to EGO at a generally lower price point, with a more diverse tool ecosystem.
How long do the batteries last?
A standard 4.0Ah battery typically lasts 45-60 minutes. However, if you are cutting wet or tall grass, run time can drop significantly. We always recommend having two batteries.
Can I leave the battery on the charger?
Greenworks chargers have smart shut-off features, but it is best practice to remove the battery once fully charged to maximize its long-term lifespan.
Does it work on hills?
The self-propelled 60V and 80V models handle hills well because they are rear-wheel drive. However, for extremely steep slopes, you should consider a specialized robotic mower with AWD.
Final Verdict
The Greenworks lineup in 2025 is stronger than ever. They have successfully bridged the gap between toy-like electric gadgets and serious landscaping equipment.
Our Recommendations:
- Buy the 80V Pro if you are transitioning from a gas mower and refuse to sacrifice power. It is a beast that eats tall grass for breakfast.
- Buy the 60V Pro if you want the best balance of weight, power, and cost for a standard suburban home.
- Buy the 40V if you are on a budget or have a small, simple yard.
Whichever you choose, you are making a solid investment in a greener, quieter lawn care routine. Say goodbye to pull cords and gas cans forever.
