Why a 2-in-1 Trimmer-Edger Combo Saves You Money and Garage Space
I used to own a separate string trimmer and a separate lawn edger. They took up two spots on my garage wall. I spent about $250 total on both tools. Then I switched to a combo trimmer-edger. One tool does both jobs. It cost less. It takes up half the space. And I do not have to switch tools halfway through yard work.
A good 2-in-1 trimmer-edger lets you trim grass around trees and fences. Then you rotate the head or shaft and edge along your driveway, sidewalk, and flower beds. The result is a clean, professional-looking yard without buying two separate tools.

1. Worx WG170.9 — Best 3-in-1 Combo Overall
The Worx WG170.9 is my favorite trimmer-edger combo because it also works as a mini mower. You twist the head 90 degrees to switch from trimming to edging. Twist it fully and add the wheels to use it as a small mower for tight spots. Three tools in one device.
At 4.6 pounds, it is light and easy to handle. The Command Feed system lets you feed line by pressing a button on the handle. No bumping. The 12-inch cutting width is fine for small to medium yards. For $69 as a bare tool, this is incredible value.
2. Black+Decker BESTA510 — Best Corded 2-in-1
The BESTA510 is a corded 2-in-1 that costs just $59. The 6.5-amp motor delivers steady power. You never worry about battery life. Just plug it in and go. The 14-inch cutting path is wider than most battery trimmers at this price.
The auto-feed system advances line automatically. The shaft rotates to convert from trimmer to edger. The edge guide wheel helps you cut straight lines along driveways and sidewalks. The tradeoff is the cord. You need a good extension cord and a plan for not cutting through it.
3. Black+Decker LSTE525 — Cordless with Easy Feed
The Black+Decker LSTE525 is a 20V cordless trimmer-edger with a standout feature. The Easy Feed button on the handle advances line with one press. You do not bump the head on the ground. This saves time and frustration.
The head rotates 180 degrees for edging mode. At 5.7 pounds with the battery, it is light enough for long trimming sessions. The 12-inch cutting path handles typical yard work. It uses Black+Decker 20V MAX batteries, the same ones used in dozens of their power tools.
4. Worx WG163.9 — Simple and Affordable Trimmer-Edger
The Worx WG163.9 is a straightforward 2-in-1 trimmer and edger. No extra modes. Just reliable trimming and edging. The 20V battery system works with over 90 Worx tools. The 4.6-pound weight makes it one of the lightest combos available.
The Command Feed system is the same as the WG170.9. Press a button on the handle to feed line. The head tilts to edging position. The telescopic shaft adjusts to your height. At $74.99 as a bare tool, this is a great entry into the Worx ecosystem.
5. Ryobi ONE+ 18V P20014 — Best for Existing Ryobi Owners
The Ryobi P20014 is a 2-in-1 trimmer-edger that runs on the massive Ryobi 18V ONE+ battery system. Over 200 tools use the same battery. If you own a Ryobi drill, saw, or blower, you already have the battery this trimmer needs.
The 13-inch cutting path is good for a lightweight trimmer. The rotating shaft converts to edging mode. The auto-feed head keeps line flowing without bumping. At $98 for the bare tool, it is affordable and reliable. The 5.5-pound weight is easy on arms.
6. Greenworks 24V 12-inch Brushless 2-in-1
The Greenworks 24V brushless trimmer-edger stands out for its warranty and included accessories. You get a 3-year warranty, 10 plastic blades, and a brushless motor. The brushless motor means longer runtime and longer tool life.
The 2-in-1 design converts between trimming and edging. The adjustable shaft and handle help you find a comfortable position. At 5.3 pounds, it is easy to handle. The 12-inch cutting width works well for typical suburban yards.
7. Black+Decker MTC220 — 3-in-1 with Mower
The Black+Decker MTC220 is a full 3-in-1 system. It includes the string trimmer, edger, and a push mower deck. The power head snaps into the mower deck to cut grass. Pop it out and use it as a trimmer or edger. This is perfect for small yards where you do not want three separate tools.
The kit comes with two 20V MAX batteries and a charger. Having two batteries means you can trim while one charges. The 12-inch trimmer path and compact mower deck work best on yards under a quarter acre. At $169 for the whole kit, you get three tools for less than the price of a standalone mower.
How 2-in-1 Edging Actually Works
There are two ways combo trimmers switch to edging mode. The first is a rotating shaft. You twist the lower shaft 180 degrees and the trimmer head turns sideways for edging. The second is a rotating head. You press a button and tilt the head 90 degrees. Both methods work. Rotating heads are faster to switch. Rotating shafts give you better visibility of the cutting line.
Some trimmers add a guide wheel for edging. The wheel rolls along the edge of your driveway or sidewalk. This keeps your cuts straight and even. It also prevents the line from scraping against concrete, which wears it down fast.
Trimmer vs Edger: What Is the Difference?
A string trimmer cuts grass horizontally. You hold it parallel to the ground and sweep side to side. It trims grass in places your mower cannot reach. Around trees, fences, mailboxes, and garden beds.
An edger cuts grass vertically. You hold it at a 90-degree angle to the ground and cut along hard edges. Driveways, sidewalks, patios, and curbs. The edger creates the clean, sharp line between your lawn and the pavement. A 2-in-1 trimmer-edger lets you do both jobs with one tool.
Corded vs Cordless for Combo Tools
Corded combo tools like the Black+Decker BESTA510 give you unlimited runtime. You never stop to charge. The motor delivers full power the whole time. Corded tools also cost less. The downside is dealing with an extension cord. For small yards with easy outlet access, corded is a smart choice.
Cordless combos give you freedom. You can trim anywhere without dragging a cord. Modern 20V and 24V batteries run 30 to 45 minutes. That covers most small to medium yards. Buy a second battery and you can trim and edge back-to-back without waiting for a charge.
