Best Electric String Trimmer Mowers for Small and Large Yards
The best electric string trimmer mower depends on whether you want a compact mower-trimmer combination, a cordless multi-tool, or a dedicated walk-behind string mower. The BLACK+DECKER MTC220 is best for small yards and hard-to-reach spaces; the corded BESTA512CM suits buyers who want continuous power; and the EARTHQUAKE model is better for covering a wider area. The other cordless options add edging and, in one case, interchangeable cutting blades.
| Product | Best For | Power Type |
|---|---|---|
| BLACK+DECKER MTC220 | Small yards and tight spaces | Cordless battery |
| BLACK+DECKER BESTA512CM | Continuous operation near an outlet | Corded electric |
| WeGofly 4-in-1 | Multiple cutting tasks | Cordless battery |
| 21V 12-inch Weed Wacker | Trimming and edging | Cordless battery |
| EARTHQUAKE 60V Walk-Behind | Wider cutting coverage | Cordless battery |
BLACK+DECKER MTC220 3-in-1 Combo
Best for: Small yards, slopes, and areas a standard walk-behind mower may not reach easily. This cordless combo works as a string trimmer, lawn edger, and compact mower. Its removable wheeled deck converts the trimmer into a small mower, while adjustable length and height help tailor the tool to the task.
The included two batteries and charger support cordless use, and the AFS automatic-feed spool advances line without requiring manual line adjustments. It is a practical choice when one tool needs to handle several small-yard jobs. Limitation: Its 12-inch cutting width and compact mower format are better suited to smaller areas than broad lawns.
BLACK+DECKER BESTA512CM Corded Combo
Best for: Buyers who want mowing, trimming, and edging functions with corded power. This 12-inch combination has a 6.5-amp motor and POWERDRIVE Transmission, which the product information identifies for cutting tough weeds and thick grass. Its AFS system feeds line automatically, without bumping or manual adjustments.
Choose this model if you prefer not to manage rechargeable batteries and can work within the reach of a power cord. It combines a compact push mower with a string trimmer and edger, making it a versatile option for smaller lawn areas. Limitation: Because it is corded, movement is constrained by access to an outlet and the cord’s reach.
WeGofly 4-in-1 Cordless Garden Tool
Best for: Buyers who want to switch among several cutting styles. The tool is described as a string trimmer, lawn edger, mini mower, and brush cutter. It includes trimmer line, metal blades, and saw blades, which can be changed for different daily cutting tasks.
Two 21V 6.0Ah batteries and a charger are included. The listed weight is 5.2 pounds, making weight a useful comparison point for shoppers prioritizing a lightweight tool. This model was selected for its range of attachments and cordless setup. Limitation: It has multiple blade types, so buyers should consider whether they want that added versatility or would prefer a simpler trimmer-and-edger design.
21V 12-Inch Cordless Weed Wacker
Best for: Small to mid-sized yards where trimming and edging are the primary needs. This 12-inch cordless trimmer has a listed 9000-RPM cutting head and converts between trimming and edging. It includes two 4.0Ah batteries and a fast charger; the product listing states up to 60–90 minutes of use.
The auto-feed and manual-feed modes offer two ways to advance line. The listing specifies that the automatic mode feeds line when the tool starts, while manual feeding uses a release button. Choose this model if you want a cordless trimmer with edging functionality. Limitation: It is not described as a wheeled mower, so it is not the best match for buyers seeking a walk-behind mower substitute.
EARTHQUAKE 60V Walk-Behind String Mower
Best for: Buyers who want a dedicated walk-behind string mower and a wider cutting path. The EARTHQUAKE model has a 22-inch cutting diameter, three cutting-speed settings, and 14-inch never-go-flat wheels. It includes two 4Ah batteries, with up to 90 minutes of runtime listed by the manufacturer.
An adjustable handlebar and easy assembly are also listed features. Compared with the compact 12-inch combo tools, its wider cutting diameter is better suited to covering more ground per pass. Limitation: It is a walk-behind string mower rather than a multi-function trimmer-and-edger combo, so it may not suit shoppers who need those specific tool modes.
Buying Guide: How To Choose An Electric String Trimmer Mower
Do you need a mower conversion or a dedicated walk-behind mower?
A convertible combo is useful when you need trimming and edging as well as occasional mowing in a small yard. A dedicated walk-behind string mower, such as the EARTHQUAKE, offers a wider listed cutting diameter and is designed for mowing larger patches of grass or weeds. Compare the cutting width with the area you need to cover.
Should you choose corded or cordless power?
A corded model can run from an outlet without battery recharging, but the cord limits where you can work. Cordless models avoid that tether and include rechargeable batteries. Compare the number and capacity of included batteries, and check whether the product listing provides a runtime estimate. Actual working time can depend on conditions and use.
Which cutting features matter most?
For routine lawn edges, a trimmer-and-edger combination may be sufficient. Choose a model with multiple blade types if you need more cutting options, and review the included attachments carefully. Automatic line feed can reduce the need for manual line adjustments, while a mower deck or wheels can make a compact combo function more like a small mower.
How should you compare comfort and coverage?
Look at cutting diameter, listed weight, wheel size, and handle adjustments. A wider cutting diameter may reduce the number of passes, while a lightweight design can be easier to maneuver. These features do not replace checking the product’s intended use: compact combos and dedicated walk-behind mowers serve different yard sizes and tasks.
Frequently Asked Questions
Can a string trimmer replace a lawn mower?
A standard string trimmer is designed for trimming, not broad lawn mowing. A combo with a removable wheeled deck or a dedicated walk-behind string mower is a better fit when you want mower-style coverage.
Is a corded electric trimmer mower suitable for a small yard?
It can suit a small yard if an outlet and cord reach the work area. The main trade-off is that the cord limits movement compared with a cordless model.
What does automatic line feed do?
An automatic-feed system advances trimmer line without requiring the user to bump the tool or manually adjust the line during ordinary operation, according to the listed features of these models.
Which option has the widest listed cutting diameter?
The EARTHQUAKE 60V Walk-Behind String Mower has the widest listed cutting diameter among these products, at 22 inches.
