String Trimmers with Edger Attachments: Top 5 Models

The best string trimmers with edger attachments combine the functionality of two essential lawn care tools into one, offering versatility and saving storage space. These tools are indispensable for achieving crisp, clean lines along driveways, sidewalks, and flower beds, elevating a yard’s appearance. As a technician with over a decade of experience in lawn care equipment, I recommend considering electric (corded or battery-powered) for small to medium yards and gas-powered for large properties or commercial use.

String Trimmer: Overview and Optimal Selection

A string trimmer, often called a weed eater or weed whacker, is primarily designed to cut grass and weeds in areas a lawn mower can’t reach. Its spinning line allows it to maneuver around obstacles like trees, fences, and garden beds. An edger attachment, or a string trimmer designed to convert into an edger, takes this functionality a step further by creating a distinct, clean cut along defined borders. This dual functionality offers remarkable versatility, saving you both money and storage space by combining two essential tools into one.

When considering a string trimmer with edger capabilities, you’ll encounter three main types: electric (corded), electric (battery-powered), and gas-powered. Each type has distinct advantages and disadvantages that cater to different yard sizes and user preferences.

• Electric (Corded): These trimmers offer consistent power without the need for refueling or recharging. They are typically lighter and produce less noise and vibration. However, their major drawback is the reliance on an electrical outlet, limiting your range and requiring careful cord management. They are generally best suited for smaller urban yards with easy access to power.
• Electric (Battery-Powered): Offering the freedom of cordless operation, battery-powered string trimmers are increasingly popular. They are quieter, produce zero emissions, and require less maintenance than gas models. Advances in battery technology mean many newer models can rival the power of light-duty gas trimmers, making them ideal for small to medium-sized yards. The primary considerations are battery run time and charge time, and the initial cost of batteries and chargers can be higher.
• Gas-Powered: For large properties, thick brush, or professional use, gas string trimmers remain the powerhouse choice. They offer maximum power and unrestricted mobility, allowing for extended use without recharging. However, they are typically heavier, noisier, require fuel mixing, produce emissions, and involve more maintenance, including spark plug and air filter changes. Starting them often involves a pull-cord mechanism, which can sometimes be finicky.

The engine type largely dictates the trimmer’s power and how it performs during both trimming and edging tasks. Corded electric models, with their continuous power supply, are excellent for consistent, light-to-medium work without interruption. Battery-powered units provide superb mobility and quiet operation, perfect for residential use where noise and emissions are concerns. Modern battery technologies, like those in 56V or 60V systems, can deliver surprising power, capable of tackling tougher tasks. Gas-powered engines, often 2-cycle, are the go-to for maximum torque and extended run times, making them suitable for large properties, commercial applications, or clearing dense overgrowth.

Power and Performance

The raw power of your string trimmer directly impacts its ability to cut through various types of vegetation and maintain a clean edge. For battery models, look at the voltage (V) – higher voltage typically means more power and potentially longer run times. Amperage (A) is the key metric for corded electric models. For gas trimmers, engine displacement in cubic centimeters (cc) indicates power. A larger cutting swath, typically ranging from 12 to 17 inches, allows you to cover more ground faster, which is particularly beneficial for larger areas. Features like variable speed control give you precision for delicate trimming around flowers and maximum power for heavy edging, while automatic or bump-feed line advancement ensures uninterrupted work.

Cutting Head and Line

The cutting head and the type of trimmer line are crucial for effective trimming and precise edging. Different line shapes offer distinct advantages:

• Round lines are standard, durable, and good for general-purpose grass trimming.
• Square lines provide sharper edges, making them more aggressive for tougher weeds.
• Multi-sided (star or twisted) lines combine durability with cutting power, excelling at cutting through denser brush.
• Twisted lines often reduce noise and enhance cutting efficiency.

Line thickness also matters. Thinner lines (0.065-0.080 inches) are ideal for light grass, while medium lines (0.085-0.105 inches) handle grass and non-woody weeds effectively. For heavy weeds and brush, a thick line (0.110 inches and above) is necessary. For edging, a robust line and a well-designed head are critical for a clean, deep cut.

Additional Features

Beyond basic cutting, several features enhance the versatility and user experience of string trimmers with edger attachments.

• Attachment Capability: This is paramount for an edger function. Many high-end string trimmers are “attachment-capable,” meaning their powerhead can accept various accessories like edgers, hedge trimmers, pole saws, and even cultivators. Brands like DeWalt, Ryobi, and Husqvarna are known for their robust attachment systems.
• Wheeled Edger Function: Some 2-in-1 models convert to a wheeled edger, providing stability and guiding the trimmer for perfectly straight lines. This feature makes achieving professional-looking edges much easier, especially for beginners.
• Shaft Design: Straight shafts offer better reach under bushes and into tight spaces, while curved shafts are often lighter and more comfortable for some users, though with less reach.
• Ergonomics and Weight: A comfortable grip, adjustable handle, and manageable weight reduce fatigue, particularly during longer tasks. Anti-vibration features are also highly beneficial, especially for gas models.
• Safety Features: Consider features like safety guards, locking mechanisms, and accessible emergency stops.

EGO Powerload 56V 15-inch Cordless String Trimmer

The EGO Powerload 56V 15-inch Cordless String Trimmer is often lauded for its user-friendliness and impressive battery performance. Its standout feature, the Powerload head, simplifies line replacement to an almost effortless push-button process, which is a huge time-saver. Users appreciate its low vibration brushless motor and the adjustable telescopic aluminum shaft, making it comfortable for various heights and tasks. While it’s slightly heavier than some other battery-powered options, its power-to-weight ratio is excellent, and many find it a worthy contender against gas models for its ability to tackle tough weeds and provide precise edges with an appropriate attachment.

DeWalt FLEXVOLT 60V MAX 17-inch Attachment Capable Trimmer

For those seeking robust power and ultimate versatility, the DeWalt FLEXVOLT 60V MAX 17-inch Attachment Capable Trimmer is a top-tier choice. This trimmer is a workhorse, offering power comparable to many professional gas models without the associated fumes and noise. Its “attachment-capable” design is key, allowing you to quickly swap out the trimmer head for a dedicated edger, tiller, pole saw, or hedge trimmer attachment, transforming it into a multi-functional yard care system. While its weight and higher price point make it a “splurge” for some, its durability and raw power justify the investment for serious homeowners or even light commercial use.

BLACK+DECKER 20V String Trimmer/Edger

The BLACK+DECKER 20V String Trimmer/Edger stands out as an excellent value option, specifically designed for seamless transitions between trimming and edging. Many models feature a quick-release button that pivots the head 90 degrees and a guide wheel, making it incredibly easy to create clean, straight edges along sidewalks and flower beds. This lightweight and compact unit is highly customizable, with optional accessories like additional batteries or a removable mower deck. While its 20V battery system is best suited for smaller to medium-sized yards and lighter tasks, its ease of use, integrated edger function, and affordability make it a fantastic choice for typical home lawn maintenance.

Using and Maintaining Your String Trimmer with Edger Attachments

Proper use and consistent maintenance are crucial for maximizing the performance and lifespan of your string trimmer with edger attachments.

Preparation Before Use

Safety should always be your top priority. Before starting any work, ensure you are wearing appropriate personal protective equipment (PPE), including safety glasses, long pants, sturdy closed-toe shoes or boots, and hearing protection, especially for gas-powered models. Check the trimmer line for wear and ensure it’s loaded correctly. If using a battery-powered model, make sure the battery is fully charged. For gas trimmers, confirm the fuel tank is adequately filled with the correct fuel mixture. Finally, inspect your work area for any debris, rocks, or obstacles that could be thrown or damage the cutting line.

Trimming and Edging Techniques

When trimming, hold the string trimmer firmly with both hands, keeping it slightly angled. Use a sweeping motion, moving from side to side, gradually advancing forward. For tough patches, use the tip of the line to “feather” the grass down. When transitioning to edging, if your model has a wheeled edger, simply pivot the head and engage the wheel along your hard surface (driveway, sidewalk). Walk slowly, allowing the wheel to guide the line for a perfectly straight and consistent edge. For attachment-capable models, swap to the dedicated edger attachment. Always aim to cut away from yourself and any bystanders to prevent debris from flying towards them.

Cleaning and Maintenance

After each use, take a few minutes to clean your string trimmer. Remove any grass clippings, dirt, and debris from the cutting head, shaft, and engine area. This prevents buildup that can hinder performance or cause overheating. For battery models, remove the battery and store it in a cool, dry place, separate from the tool. For gas models, periodically check the air filter and spark plug, cleaning or replacing them as needed according to the manufacturer’s instructions. Keep the trimmer line fresh; old, brittle line can break easily. Proper storage in a dry, protected area will prevent rust and extend the tool’s life.

Their staff can also provide advice and answer questions.
