Top 4 Best Cordless Electric Lawn Mower Weed Eater Combos

Your garage is a graveyard of half-broken lawn tools. The gas trimmer won’t start after winter, the extension cord tangles every time you edge the driveway, and the mower is too big for that awkward strip behind the fence. You need one tool that handles it all without the fuss.

A cordless electric combo—mower, trimmer, and sometimes edger in one—cuts the clutter and the noise. The best ones share batteries, switch modes in seconds, and handle small to mid-size yards without a single drop of gas. But not every combo fits every lawn, and the trade-offs matter.

We tested and compared four leading models, from a compact 3-in-1 that transforms into a mini mower to a heavy-duty brush cutter with steel gears. Below, you’ll find a spec comparison, honest reviews of each, and a clear winner for most homeowners. If you want to see more dedicated options, check our cordless mower guide or our weed eater roundup.

Here’s a quick look at how the four stack up on the specs that drive your buying decision.

BLACK+DECKER MTC220 Combo

This 3-in-1 is the Swiss Army knife for small, awkward yards. The wheeled deck pops off, turning the trimmer into a 12-inch push mower. That means you can mow a tiny front lawn, then convert back to trim edges and slopes without hauling a second machine. It’s perfect for townhouses, cabins, or anyone tired of wrestling a full-size mower up a hill.

The PowerDrive transmission keeps the line spinning through dense grass without bogging down, and the AFS auto-feed spool means you won’t stop every few minutes to bump the head. It runs on two included batteries, so you can swap when the first drains. The adjustable handle and height settings make it comfortable for different users.

Honest trade-off: the mower deck is small, so it’s slow on anything larger than a postage-stamp lawn. And while the batteries are fine for trimming, they may not finish a big mowing session on one charge. You’ll be fine unless your yard is over a quarter acre—then look for a dedicated mower.

• Converts between mower, trimmer, and edger without tools
• Two batteries included—keep one charging while you work
• AFS auto-feed spool prevents line jams
• 12-inch cutting width on the mower deck
• Adjustable height and length for comfort

Best for: Homeowners with small, sloped, or oddly shaped yards who want one tool to do it all.

BLACK+DECKER BESTA512CM

If you have an outlet within reach of every corner of your lawn, this corded combo saves you from battery anxiety. The 6.5-amp motor with PowerDrive transmission delivers consistent power—no fading as the battery drains. The 12-inch cutting width and 8,000 RPM handle thick grass and weeds without stalling.

It’s a true 3-in-1: the trimmer head tilts for edging, and the wheeled attachment turns it into a compact mower. The AFS auto-feed spool keeps the line advancing automatically, so you won’t bump the head to get more line. At just over 10 pounds, it’s light enough to carry up steps or use overhead for hard-to-reach spots.

The catch is the cord. You’ll be swapping outlets or using an extension cord, and the cord can get in the way when you’re maneuvering around flower beds. It’s also not ideal for large properties—the 12-inch deck means more passes. But for small lawns where an outlet is handy, this is a reliable workhorse.

• 6.5-amp motor never loses power—consistent performance
• 12-inch cutting width, 1.6-inch height adjustment
• Converts to edger with a simple twist
• AFS auto-feed spool for continuous trimming
• Lightweight, adjustable handle for comfort

Best for: Budget-conscious buyers with small, flat lawns and easy access to outdoor outlets.

YOPTWX 21V Combo Kit

This kit pairs a cordless weed wacker with a handheld leaf blower, so you can trim and then blow clippings off the driveway without switching tools. It’s a smart pairing if your routine is more about tidiness than heavy mowing. The trimmer uses four types of cutting blades—plastic for delicate grass, rhombus for thick weeds, U-blade for reeds, and saw blade for branches—so you can adapt to whatever is growing.

The telescoping pole extends from 35 to 47 inches, and the head tilts 90 degrees, which makes reaching under shrubs or along fences much easier. It also folds for compact storage. The two included batteries give 90–120 minutes of runtime without load, or 60–90 minutes of actual work. The leaf blower shares those batteries, so you won’t be stuck with a dead blower.

What’s not perfect: the blade system means you’re not using traditional trimmer line, so it can be harsher on delicate plants if you’re not careful. Also, there’s no mower deck, so this won’t replace your lawnmower. It’s a trimmer and blower combo, not a full-yard solution. If you already have a mower, this fills the gaps nicely.

• Includes trimmer, leaf blower, and weed collection bag
• Four blade types for different vegetation
• Adjustable pole (35–47 inches) and 0–90° head
• Two high-capacity batteries included
• Folds down for storage

Best for: Homeowners who want to trim edges and blow leaves with one cordless system, without needing a mower attachment.

WeGofly 14-inch 4-in-1

This one’s for the serious yard warrior. The WeGofly runs a 15,000 RPM brushless motor with steel gears, so it chews through overgrown weeds, small shrubs, and even branches. The 14-inch cutting width means fewer passes than the 12-inch models. It converts to a string trimmer, edger, mini mower, and brush cutter—all with the included attachments.

The two 21V 6.0Ah batteries are the biggest in this roundup, giving you the longest runtime. The brushless motor is more efficient and durable than brushed motors, and the steel gear set prevents the burnout that plagues cheaper trimmers. It’s also lightweight and ergonomic, with an adjustable handle and head, so it’s friendly for seniors or anyone with arm fatigue.

The trade-off is complexity. With four modes and multiple blades, there’s a learning curve, and you’ll need to switch attachments more often than with a simple trimmer. The mini mower deck is still small—good for tight spots, but not a full-yard mower. And while the battery life is excellent, charging two 6.0Ah packs takes time. But if you have a tough, overgrown lot, this tool will save you hours.

• Brushless motor with 15,000 RPM and steel gears
• Two 6.0Ah batteries for extended runtime
• 4-in-1: trimmer, edger, mower, brush cutter
• 14-inch cutting width for efficiency
• 3-year warranty on main unit, 2-year on batteries

Best for: Owners of larger, overgrown, or brush-heavy properties who need serious cutting power and long runtime.

How We Chose These Products

We started with the real-world scenarios: small lawns, steep slopes, thick weeds, and the need to store everything in a shed. Each product had to offer at least two functions—mowing, trimming, or edging—and come with a battery system or cord that made sense for its intended use. We prioritized models with auto-feed spools or blade systems that reduce downtime, and we looked at cutting width and motor power to gauge how fast they’d finish a job.

We also weighed portability, adjustable features, and included accessories. A combo that folds or converts without tools scores points. Battery count and amp-hours matter for cordless models. And we factored in warranty and support, since lawn tools take a beating. We didn’t include any product we wouldn’t recommend to a neighbor, and we avoided overhyped specs.

Buying Guide: What Really Matters

Before you buy, measure your yard. A 12-inch cutting width is fine for a small lawn, but if you have a quarter acre or more, you’ll want a 14-inch or a dedicated mower. Also consider the terrain: slopes and uneven ground are easier with a lightweight, wheeled deck that you can tilt.

Battery runtime is the biggest cordless concern. Look at amp-hours (Ah)—higher means longer. Two batteries are better than one, so you can charge one while using the other. For corded models, the motor amperage (like 6.5 amps) tells you power, but you’re limited by cord reach. Think about where your outlets are.

Finally, think about the tasks beyond trimming. Do you edge along sidewalks? Then a tilting head is essential. Do you have brush or brambles? Then a metal blade option beats standard line. And if you need to blow clippings afterward, a combo with a blower saves a separate purchase. Match the tool to your actual weekly routine, not the dream yard.

Our Top Recommendation

The BLACK+DECKER MTC220 is our overall pick for most homeowners. It’s the only one that truly replaces three tools—mower, trimmer, and edger—in a single cordless system. The wheeled deck transforms it into a mini mower that handles small lawns and slopes, and the AFS spool keeps you working without interruptions. It’s not the most powerful for heavy brush, but for everyday yard maintenance, it’s the most versatile and convenient.

If your yard is bigger or more overgrown, the WeGofly 14-inch is the runner-up for its brushless motor, steel gears, and long battery life. And if you’re on a tight budget and have an outlet nearby, the BLACK+DECKER BESTA512CM offers reliable corded power at a lower price. For those who just need trimming and leaf cleanup, the YOPTWX combo kit is a smart value.

No matter which you choose, check the current price on Amazon—they fluctuate. And if you’re still weighing options, our push mower guide covers standalone mowers, or see models with battery and charger for more ideas.

Frequently Asked Questions

Can I use a cordless weed eater as a lawn mower?

Only if it has a wheeled attachment, like the BLACK+DECKER MTC220 or WeGofly. These convert the trimmer head into a small push mower, but they’re best for tiny lawns or touch-ups. For a regular yard, you’ll want a dedicated mower.

How long do the batteries last on a cordless combo?

It depends on the battery capacity and the task. The YOPTWX claims 60–90 minutes of actual work with its two batteries. The WeGofly’s 6.0Ah batteries last longer, but heavy cutting in thick grass drains them faster. Always have a second battery charged.

What’s the difference between a string trimmer and a brush cutter?

A string trimmer uses flexible line for grass and light weeds. A brush cutter uses metal blades to slice through thick brush, small shrubs, and branches. The WeGofly and YOPTWX include blade options, so you can switch based on what you’re cutting.

Are corded or cordless combos better?

Cordless gives you freedom and no cord hassle, but you’re limited by battery life. Corded (like the BESTA512CM) offers unlimited runtime and consistent power, but you need an outlet nearby and must manage the cord. Choose cordless for convenience and portability; choose corded if you have a small yard and don’t mind the cord.
