Black+decker 3 in 1 cordless lawn mower review: the specs at a glance

Who the BLACK+DECKER MTC220 is for

This kit is for the homeowner whose yard defeats a full-size mower: small lawns, slopes, and the strips and corners a walk-behind cannot reach. The trimmer handles edges and weeds, the edger cleans up along paths, and the removable MTD100 deck turns the tool into a 12 inch push mower for small patches of grass. Two LBXR2020 20V MAX batteries and a charger come in the box, so one battery can charge while the other works. If your mowing is measured in minutes rather than acres, one tool doing three jobs is the appeal.

The pick

BLACK+DECKER MTC220, a 20V cordless 3-in-1 trimmer, edger and 12 inch mower combo with two batteries, charger, AFS automatic feed spool, PowerDrive transmission and adjustable deck height, backed by a 2 year limited warranty.

What 3-in-1 means in practice

The three modes share one power head. As a trimmer it is a standard 20V string trimmer with an AF-100 spool, an auxiliary handle and a guard; as an edger the head pivots for vertical cutting along driveways and beds; as a mower the trimmer clips into the removable wheeled MTD100 deck for a 12 inch cutting width. Switching modes is the product’s reason to exist: one battery platform, one tool to store, three jobs covered. The listing does not state a runtime figure, so how long two batteries last across all three modes is unconfirmed. The 12 inch mower width is honest about its scope: this is for patches and touch-ups, not for mowing a lawn end to end.

The conversion itself is the product’s core trick. The MTD100 is a removable wheeled deck: dock the LST220 trimmer into it and you have a 12-inch push mower; lift it out and you are back to a string trimmer. The trimmer head pivots into edger mode for the third function, and the pivoting handle adjusts to the task. The auxiliary handle and guard come in the box, so the trimmer is fully kitted from day one. In mower mode the 12-inch width suits patches and strips; in trimmer mode the head reaches where no deck can go, which is why the listing aims it at slopes and areas that are tough to reach with standard walk-behind mowers.

What the MTC220 does well

Three genuine tools, one battery platform

The trimmer, edger and mower modes are all real functions, not attachments in name only: the pivoting head, the adjustable deck height and the wheeled mower deck each do their job. For a small yard with edges, slopes and a patch of lawn, one kit replaces three separate tools.

Two batteries in the box

Two LBXR2020 20V MAX batteries and a charger are included, which matters on a tool with three jobs to do. One battery works while the other charges, and 20V MAX is BLACK+DECKER’s common platform, so the batteries suit other tools you may own.

AFS automatic feed, no bumping

The AFS automatic feed spool advances the line without bumping the head or stopping to adjust, per the listing. That keeps trimming continuous, which is the difference between a quick edge job and a fiddly one.

PowerDrive against bogging

The PowerDrive transmission is listed as preventing bogging in dense grass and weeds. On a 20V trimmer, sustained power under load is the weak point, so a transmission aimed at that exact problem is worth noting.

Limitations to know before you buy

12 inches is a patch mower, not a lawn mower

The mower deck cuts 12 inches wide. That suits small patches, slopes and areas a walk-behind cannot reach, which the listing names outright. It does not suit mowing a whole lawn; a full-size mower is the tool for that.

No runtime figure stated

The listing claims continuous operation for the feed spool but gives no minutes per battery. Runtime across trimmer, edger and mower modes is the number that decides whether two batteries finish your yard, and it is missing.

Mower mode needs the deck

The mower function depends on the detachable MTD100 deck. It is a conversion, not a dedicated mower: expect a light-duty cut, and keep the deck attached only for the patches it suits.

Line diameter not stated

The AF-100 spool is included but its line diameter is not listed. Without the figure, we cannot say what weeds it will handle.

Getting the most from the two batteries

Rotate the batteries between the tool and the charger as you work. Use the trimmer for what it does best, edges and weeds, and save the mower deck for the small patches it is sized for rather than forcing it across the whole lawn. Keep the AFS spool wound and the guard on; a clean head feeds line better than a clogged one. After the season, store the batteries indoors at a partial charge.

The two LBXR2020 20V MAX batteries are the work rhythm of this kit: run one down, swap in the second, and put the first on the charger. The listing names PowerDrive transmission as the anti-bogging feature, which matters because a 20V trimmer motor works hardest in dense grass and weeds. Keep the AF-100 spool fed with line, since the AFS automatic feed only advances what is on the spool, and store the batteries indoors between sessions rather than in a freezing shed.

Who should skip the BLACK+DECKER MTC220

Skip it if you mow a real lawn: a 12 inch converted deck is not a substitute for a walk-behind. Skip it if you need heavy brush cutting, since the line diameter is unstated and the tool is built for grass and weeds. And skip it if you already run another battery platform and do not want a second charger and battery type on the shelf.

Matching it to your property

On small suburban lots, slopes and townhouse yards, this kit covers the whole job: trim the edges, edge the paths, mow the patch. On larger properties it is a complement to a real mower, handling the trimmer work and the spots the big machine cannot reach. In spring it cleans up winter debris along beds; through summer it is the weekly edge-and-touch-up tool. Year-round, keep the deck clean and the spool fed, and the three modes stay ready.

The 9.9 lb item weight is the figure that makes the slope story work: this is a tool you carry up a bank one-handed, not a machine you wrestle. The 40.5 by 15.25 inch footprint hangs on a garage wall or stands in a shed corner without claiming floor space. For a townhouse yard or a sloped lot where a walk-behind mower is overkill and a lone trimmer leaves the patch unmowed, the three modes between them cover the whole property.
