Best Weed Eater For Lawn Mower: Mower-and-Trimmer Combos

#1 · Best Overall

1. BLACK+DECKER MTC220

• Weight: 9.9 lb
• Size: 12-Inch

Best for: Small yards and tight spaces.

Why it ranks #1: Its removable wheeled deck converts the 12-inch tool among mower, trimmer, and edger modes, and the package includes two batteries and a charger.

A removable wheeled mower deck turns the BLACK+DECKER MTC220 from a string trimmer into a compact mower, then lets it work as an edger. That conversion suits smaller yards, slopes, and hard-to-reach patches where a standard walk-behind mower can be awkward to maneuver.

The 12-inch cutting size and 9.9-pound listed weight make this a compact option for piecemeal lawn care, while the detachable deck supports switching between mowing and trimming without keeping separate machines. Its AFS automatic-feed spool advances line without bumping, helping maintain a steady trimming workflow. Two included 20V MAX batteries and a charger are supplied, and adjustable length and height let you set up the tool for the task at hand.

Skip it if you need to cover a broad lawn quickly; the 12-inch deck is compact, while Greenworks' 21-inch mower kit offers a wider cutting path.

Choose this for a smaller yard, sloped ground, or lawn edges that call for frequent changes between mowing and trimming. Its 12-inch deck is a practical fit for compact areas, not a wide-lawn mowing substitute.

#2 · Best Corded Option

2. BLACK+DECKER BESTA512CM

• Weight: 9.9 lb
• Dimensions: 15"D x 7"W x 37"H

Best for: Corded compact-yard combo.

Why it ranks #2: This 12-inch corded combo changes between mower, trimmer, and edger, with a 6.5-amp motor and automatic line feed.

A 6.5-amp motor with POWERDRIVE transmission gives this corded BLACK+DECKER combo the power to tackle tough weeds and thick grass while serving as a mower, trimmer, and edger. Its detachable deck makes it possible to move from compact mowing to detail work with one tool.

The 12-inch mower format keeps the tool suited to compact areas, and removing the deck changes it into a string trimmer for lawn edges and overgrowth. Rotate the trimmer to edge, then let the AFS spool feed line without bumping or manual adjustment. Because this model is corded, it runs from an electrical connection rather than the included battery-and-charger setup found in cordless kits; plan the mowing route around access to power.

Skip it if you want to work away from an electrical connection; the cordless BLACK+DECKER MTC220 includes two batteries and a charger.

This suits a compact yard where a corded tool can reach the work area and a single machine can mow, trim, and edge. Choose another format if routing a cord would interrupt your lawn-care workflow.

#3 · Best Battery Pair

3. LawnMaster 20VMWGT

• Weight: 5.3 lb
• Size: 5.51 in
• Dimensions: 20.59"D x 12"W x 25.82"H

Best for: Mower-and-trimmer pairing.

Why it ranks #3: The kit pairs a 13-inch mower with a 10-inch trimmer and includes two 4.0Ah batteries and a charger.

A 13-inch mower and separate 10-inch grass trimmer give the LawnMaster 20VMWGT combo two distinct tools for lawn coverage and edge work. It includes two 24V Max batteries and a charger, while the mower offers five cutting heights for adjusting its cut to the yard.

The mower's 13-inch width and five height settings support compact mowing with some adjustment over the finished cut. For boundaries and tighter patches, the 10-inch trimmer has a dual-line auto-feed head, so line advances without manual pulling. Its pivoting assist handle and cutting head provide adjustment while trimming. The included pair of 24V Max 4.0Ah batteries and charger means the kit arrives with its stated power components, rather than requiring a separate battery purchase.

Skip it if you want a 20-inch mower deck for broader coverage; the Greenworks 48V 20-inch combo has a wider listed cutting width.

This is a fit for buyers who want a compact mower and dedicated trimmer, with batteries and charger included. Its 13-inch mower width makes more sense for smaller areas than for covering a broad lawn quickly.

#4 · Widest Mower Deck

4. Greenworks 20-Inch Combo

• Weight: 48 lb
• Dimensions: 56"D x 21"W x 45"H

Best for: Three-tool battery yard kit.

Why it ranks #4: Its 20-inch steel-deck mower is supplied with a 12-inch trimmer, blower, three batteries, and two chargers.

A 20-inch steel-deck mower, 12-inch string trimmer, and 320-CFM blower come together in this Greenworks 48V combo. The mower's intelligent power-cutting system maintains consistent speed, while Turbo mode raises blade speed to 3,250 RPM for thick or wet grass, according to the supplied product details.

The mower is rated for up to 30 minutes of runtime with two fully charged 4Ah USB batteries, with actual runtime varying by grass conditions and operator technique. Its 20-inch deck offers a wider mowing path than the included 12-inch trimmer's cutting path, making the trimmer useful for edges and narrower patches. Three batteries and two chargers are included, and the platform description says Greenworks 24V tools can share a PowerAll 24V battery.

Skip it if you need a stated mower runtime beyond 30 minutes per two-battery charge; Greenworks' 48V 21-inch kit lists no runtime figure here.

This fits buyers seeking mowing, trimming, and blowing tools on a Greenworks battery platform, with Turbo mode for thicker or wet grass. Factor the stated runtime variation into plans for larger or demanding lawns.

Listed on Amazon as: Greenworks 48V (2x24V) Electric Lawn Mower Combo Kit: 20"Steel Deck Push Mower, 12" String Trimmer, 320 CFM Blower, 3 Batteries & 2 Chargers, 3-Year Warranty.

#5 · Self-Propelled Pick

5. Greenworks 21-Inch Kit

• Weight: 78.3 lb
• Dimensions: 43.11"D x 17.13"W x 22.83"H

Best for: Battery-powered whole-yard kit.

Why it ranks #5: The kit includes a 21-inch self-propelled mower with a 12-inch trimmer, plus a blower; its mower offers mulching, bagging, and side discharge.

A 21-inch self-propelled mower anchors Greenworks' 48V kit, with a 12-inch string trimmer and blower included to carry lawn care beyond mowing. The mower's brushless motor and three-in-one cutting system support a broader routine, from choosing a grass-disposal method to finishing edges and clearing debris.

The mower offers mulching, rear bagging, and side discharge, so you can select how to handle cut grass for the task. Seven height positions give additional control over cutting height, while self-propulsion helps move the 21-inch mower through the yard. The included 12-inch trimmer is suited to tighter areas, and a 320-CFM blower handles cleanup. Vertical storage is a helpful feature when the kit is not in use, though the listed kit weight is 78.3 pounds.

Skip it if you want a lightweight mower-trimmer pairing; the 5.3-pound-listed LawnMaster 20VMWGT is a smaller combo option.

Pick this kit for buyers who want a self-propelled mower alongside a trimmer and blower, plus multiple clipping options. Account for the listed 78.3-pound weight when moving the kit and planning storage.

#6

6. Gisam YL-30

• Size: 18.9"

Best for: Wheeled mower-and-edger combo.

Why it ranks #6: The listed 18.9-inch cordless 3-in-1 combines a mower, string trimmer, and wheeled edger, with two 4.0Ah batteries.

An 18.9-inch cordless mower, string trimmer, and wheeled edger are combined in Gisam's three-in-one yard tool. Its brushless motor and two included 4.0Ah batteries distinguish the setup, while adjustable height and angle provide ways to position the tool for different lawn tasks.

The wheeled design supports a mower-style approach to grass cutting and an edging role, while the string-trimmer function covers work that calls for a handheld tool. Adjustable height and angle let the user change the tool's position across those tasks. The supplied title lists two 4.0Ah batteries and three blades, so the kit includes spare cutting options and battery capacity on hand. The stated 18.9-inch size is a consideration when choosing a tool for narrower areas.

Skip it if you mainly need a narrow handheld trimmer; the Givilo 11-inch weed wacker has a smaller listed cutting width.

Consider this for buyers seeking a wheeled cordless tool that combines mowing, trimming, and edging, with two batteries supplied. Its 18.9-inch stated size is worth weighing for narrow edges or confined work areas.

Listed on Amazon as: 18.9" Cordless Lawn Mower, String Trimmer & Wheeled Edger 3-in-1 Combo, Brushless 2 4.0Ah Batteries, 3 Blades, Adjustable Height & Angle Electric Weed Eater and Lawnmower

#7

7. WeGofly WEG21T

• Size: 13-Inch
• Dimensions: 33"L x 8"W

Best for: Multi-function cordless yard tool.

Why it ranks #7: Its 13-inch cordless tool covers trimming, edging, mini mowing, and brush cutting, and comes with two 21V 6.0Ah batteries.

Four functions—string trimming, edging, mini mowing, and brush cutting—make the WeGofly a flexible option for mixed yard tasks. Its 13-inch format and included pair of 21V 6.0Ah batteries give the tool a compact cutting profile with batteries and charger supplied.

Switching among trimmer, edger, mini mower, and brush cutter roles lets one tool address lawn edges, overgrown weeds, and small shrubs, according to the product details. Steel gears are specified, and the 5.2-pound listed weight supports handling a tool intended for varied yard work. Two 21V 6.0Ah batteries and a matched charger are included. A storage bag keeps accessories, screws, and blades together after use, helping organize the supplied components between jobs.

Skip it if you want a wheeled mower for larger lawn passes; the Greenworks 48V 21-inch kit includes a self-propelled mower.

This suits buyers who want one cordless tool for trimming edges, mini mowing, and cutting weeds or small shrubs. Its handheld 13-inch format is better matched to varied detail work than broad, mower-style coverage.

Listed on Amazon as: 13" Electric Weed Wacker, 4 in 1 Cordless String Trimmer/Lawn Edger/Lawn Mower/Brush Cutter with Steel Gears, 2×21V 6.0Ah Batteries & Charger, 5.2 LBS Lightweight Grass Trimmer for Yard Garden

#8

8. LIONTOTO 3-in-1

• Dimensions: 1"L x 1"W

Best for: Foldable cordless multi-tool.

Why it ranks #8: This cordless tool converts among trimmer, wheeled brush cutter, and edger, with two blades and a string option; mower performance details are limited.

A foldable three-in-one design lets the LIONTOTO switch between string trimming, lawn edging, and a wheel-supported mini-mower or brush-cutter role. Its 19,000-RPM motor and two 2.0Ah batteries are paired with round and square blades plus a trimming-line option.

The wheel-supported configuration helps guide the tool for edging or brush-cutting work, while the foldable design supports storage after use. Two blades and trimming line give the operator different cutting options for light flower-bed trimming or thicker brush, as described in the product details. The listing states a one-hour runtime and includes two 2.0Ah batteries. That runtime figure is useful for planning, though the supplied details do not specify the conditions for it.

Skip it if you need a mower with a stated 20-inch deck; the Greenworks 48V 20-inch combo lists that wider mower format.

This fits buyers looking for a foldable cordless tool for light trimming, edging, and brush work with multiple cutting options. Treat the stated one-hour runtime as a planning boundary, not a substitute for a full-size mower.

Listed on Amazon as: Foldable 3-in-1 Cordless String Trimmer/Lawn Edger/Mini Mower – 2×2.0Ah Battery Weed Wacker/Upgraded Wheeled Design, Adj Handle, Round/Square Blades&Trimming Line, 1H Runtime for Brush/Weeds/Grass

#9

9. ALSO GO 21V Trimmer

• Size: 12 in
• Dimensions: 49.21"L x 12"W

Best for: Auto-feed daily trimming.

Why it ranks #9: It is a 12-inch cordless trimmer with two 2.5Ah batteries and automatic line feed, but the listed functions do not include mowing.

A 9,500-RPM motor and 12-inch cutting path give the ALSO GO weed wacker a defined setup for routine trimming and edging. Its automatic line-feed system extends line as needed and trims excess at startup, helping avoid manual pulling or bumping during the job.

The 12-inch cutting path covers a useful strip while trimming lawn boundaries and garden areas, and the automatic feed system senses line length before extending more. A built-in blade trims excess line at startup, keeping line preparation part of the tool's operating sequence. The package includes two 2.5Ah batteries and 10 spare spools, giving the owner replacement line supplies and battery capacity for planned maintenance work.

Skip it if you need a stated 30-minute runtime with a 4.0Ah battery; the Givilo GTD20E lists that pairing.

Choose this for regular edging and trimming where automatic line feed and a 12-inch path suit the work. It includes two 2.5Ah batteries and spare spools, but the supplied details do not state a runtime.

#10

10. Givilo GTD20E

• Size: 11 Inch
• Dimensions: 33"L x 8"W

Best for: DeWalt-battery trimmer owners.

Why it ranks #10: This 11-inch cordless trimmer accepts compatible DEWALT 20V MAX batteries, but batteries are not included and it has no mower function.

Compatibility with DeWalt 20V MAX lithium-ion batteries lets the Givilo 11-inch weed wacker use batteries from that platform for cordless trimming. Its brushless motor and dual safety switch add two practical considerations: motor design for trimming work and a safeguard against accidental starts.

For a buyer who already owns a listed compatible DeWalt 20V MAX battery, this tool can be used without adding a separate battery platform; the product is sold tool-only, with battery and charger not included. The supplied facts state up to 30 minutes of nonstop trimming when paired with a 20V 4.0Ah battery. An 11-inch cutting width suits focused trimming around a yard, while the dual safety switch helps prevent accidental starts.

Skip it if you need a battery and charger in the box; the LawnMaster 20VMWGT combo includes two 4.0Ah batteries and a charger.

Choose this for trimming when you already have a compatible DeWalt 20V MAX battery, especially if an 11-inch cutting width fits your work. Remember that the tool-only package does not supply a battery or charger.
