Greenworks 40V 13-Inch Cordless String Trimmer
Excellent balance of power and runtime for medium to large yards.
Greenworks 40V 13-Inch Cordless String Trimmer (ST40B210)
Best OverallPros
- Excellent runtime on a single charge
- Automatic line feed works reliably
- Good build quality for the price
Cons
- Not as powerful as gas models for thick brush
- Battery and charger sold separately in some kits
The Greenworks 40V 13-Inch String Trimmer is the sweet spot in the lineup. It uses a 40V battery that provides enough power to handle standard grass and weeds without the weight penalty of the 80V models. Owners consistently report being able to trim a typical quarter-acre lot on a single charge.
The automatic line feed system is a significant upgrade over bump-feed mechanisms, saving time and frustration. The adjustable handle and telescoping shaft make it comfortable for users of different heights. It is a direct competitor to the Ryobi 40V and DeWalt 20V MAX trimmers, offering comparable performance at a lower price point.
Greenworks 80V 16-Inch Cordless String Trimmer
Best for Heavy DutyPros
- Power comparable to gas trimmers
- Wide 16-inch cutting path
- Brushless motor for longevity
Cons
- Heavier and more expensive
- Battery takes longer to charge
The Greenworks 80V 16-Inch String Trimmer is the brand's most powerful cordless model, designed to tackle thick weeds, brambles, and overgrown properties. It uses a brushless motor and a high-capacity 80V battery to deliver gas-like performance without the noise, fumes, or maintenance.
The wider 16-inch cutting head means you can finish large areas faster. However, the weight is a significant factor at 11.5 pounds, which can be tiring for extended use. It is best suited for users with large properties who need a gas alternative. The 80V battery is also compatible with the full Greenworks 80V range of tools.
Greenworks 24V 12-Inch Cordless String Trimmer
Best Budget / Small YardsPros
- Very lightweight and easy to handle
- Low entry cost for small gardens
- Quiet operation
Cons
- Limited runtime for larger yards
- Manual line feed is less convenient
The Greenworks 24V 12-Inch String Trimmer is the entry-level model, perfect for small gardens, patios, and light trimming tasks. It is extremely lightweight at just 5 pounds, making it ideal for users who find heavier tools difficult to manage. The 24V battery is shared with the Greenworks 24V range of tools.
Owner reviews note that it is fine for grass but struggles with thicker weeds. The manual line feed requires you to stop and push a button to advance the line. It is not a heavy-duty tool, but for the price, it is a capable starter strimmer for a small yard or for use by a less experienced gardener.
Greenworks 40V 15-Inch Cordless String Trimmer (ST40B410)
Best for Larger LawnsPros
- Wider cutting path for faster work
- Brushless motor for better efficiency
- Comfortable adjustable handle
Cons
- Slightly heavier than the 13-inch model
- Battery not included in some kits
The Greenworks 40V 15-Inch String Trimmer is an upgraded version of our top pick, featuring a wider 15-inch cutting head and a brushless motor. The brushless motor provides more torque and longer runtime compared to the brushed motor in the 13-inch model. This makes it a better choice for larger lawns where you need to cover more ground quickly.
It retains the automatic line feed system and adjustable handle of the 13-inch model. The main trade-off is the slight increase in weight. For users with a half-acre or more, the extra cutting width and efficiency of the brushless motor justify the higher price.
Greenworks 80V 17-Inch Cordless String Trimmer (Attachments Capable)
Best VersatilityPros
- Accepts multiple attachments (edger, blower)
- Very powerful brushless motor
- Widest cutting path in the range
Cons
- Heaviest model in the lineup
- Attachments sold separately
The Greenworks 80V 17-Inch Attachments Capable String Trimmer is the most versatile model in the range. It uses the same powerful 80V system but features a split-shaft design that allows you to attach other tools like an edger, pole saw, or blower. This makes it an excellent choice for users who want a single power head for multiple garden tasks.
With a 17-inch cutting width, it is the fastest at covering ground. However, it is also the heaviest model at 12 pounds. The bump-feed line system is standard. It is a direct competitor to the Ryobi 40V Expand-It system and the DeWalt 60V FlexVolt attachments capable trimmer, but uses the higher voltage 80V battery for more power.
| Model | Best For | Cutting Width | Voltage | Line Feed | Rating |
|---|---|---|---|---|---|
| 24V 12-Inch | Small yards / Budget | 12 inches | 24V | Manual | 4.0 / 5 |
| 40V 13-Inch | Best Overall | 13 inches | 40V | Automatic | 4.5 / 5 |
| 40V 15-Inch | Large Lawns | 15 inches | 40V | Automatic | 4.4 / 5 |
| 80V 16-Inch | Heavy Duty | 16 inches | 80V | Bump | 4.3 / 5 |
| 80V 17-Inch Att. | Versatility | 17 inches | 80V | Bump | 4.2 / 5 |
Who is a Greenworks Strimmer For?
Greenworks strimmers are designed for homeowners who want a battery-powered alternative to gas trimmers. They are ideal for users who already own other Greenworks tools and want to share batteries. The 24V range is for small gardens and light use. The 40V range is the best fit for most medium-sized yards. The 80V range is for heavy-duty tasks and large properties where gas-like power is needed.
Performance and Power
Performance varies significantly across the voltage ranges. The 24V model is suitable for light grass trimming. The 40V models provide enough power for standard grass and weeds. The 80V models can handle thick brush and overgrown areas. Owner reviews on retailer sites consistently praise the 40V and 80V models for their power, though some note that the 80V models are heavier. All models are quieter than gas trimmers and require no fuel mixing.
Build Quality and Warranty
Greenworks tools are generally well-regarded for their build quality at their price point. The 40V and 80V models feature brushless motors for longer life and better efficiency. The 24V model uses a brushed motor. Greenworks offers a 4-year warranty on the tool and a 2-year warranty on the battery, which is competitive with other major brands. Some users have reported issues with the automatic line feed on the 40V models, but overall reliability is good.
Alternatives to Greenworks
If Greenworks does not suit your needs, consider these alternatives. Ryobi offers a similar 40V range with a wider selection of tools in the same battery platform. Stihl offers professional-grade battery trimmers with superior build quality but at a higher price. DeWalt and Makita offer 20V/18V trimmers that are great if you are already in their ecosystems. For budget-conscious buyers, Black+Decker offers a range of affordable cordless trimmers.
What to Check Before Buying a Greenworks Strimmer
First, check your yard size. For under 1/4 acre, the 24V model is sufficient. For 1/4 to 1/2 acre, the 40V 13-inch model is ideal. For over 1/2 acre, consider the 40V 15-inch or 80V models. Second, check the battery ecosystem. If you already own Greenworks tools, choose a model that uses the same battery voltage. Third, consider the cutting width. A wider cutting path means faster work but a heavier tool. Fourth, decide on line feed type. Automatic is more convenient than bump or manual feed.
Mistakes to Avoid
A common mistake is buying a 24V model for a large yard. It will run out of battery quickly and may not have enough power for thicker weeds. Another mistake is ignoring the weight of the 80V models. They are heavy and can be tiring to use for extended periods. A third mistake is buying a tool-only kit if you do not already own a compatible battery and charger, as this will require an additional purchase. Always check what is included in the kit.
