The Black and Decker 20V MAX string trimmer converts between a trimmer and a wheeled edger without tools, runs on the 20V MAX battery platform shared across Black and Decker's cordless lineup, and includes two batteries to extend session length.
It suits homeowners managing residential lawns, fence lines, and sidewalk edges who want a lightweight, cord-free option with smart line feed. The included batteries are standard capacity, and users with larger properties or longer sessions may find it worthwhile to add a higher-capacity 20V MAX battery.

Fence Lines, Sidewalk Edging, and Maintained Residential Lots on a Single Battery Platform
If you already own Black and Decker 20V MAX tools such as a hedge trimmer or drill, the batteries from those tools will run this trimmer directly, which effectively extends your available runtime without purchasing additional batteries.
The wheeled edger conversion lets you run a clean line along driveways and sidewalks without switching to a separate tool, and the single wheel provides enough tracking control for straight edges on flat pavement. The adjustable handle length accommodates a range of user heights and also shortens for compact storage.
EASYFEED advances the trimmer line with a button push rather than the bump-feed mechanism common on lower-cost trimmers, which reduces the frustration of line advancement during a session. Two speed settings let you conserve battery on light grass trimming and shift to higher torque when cutting through thicker weeds or doing edging work that draws more power.
What to Expect from the Black and Decker 20V MAX Trimmer in Real Use
For residential fence line trimming, sidewalk edging, and general grass cleanup, the trimmer performs consistently with adequate power on both speed settings. Users coming from corded trimmers note the cordless format is a meaningful improvement for mobility, and the lightweight build makes it manageable for extended sessions, including for older users and those who find heavier tools fatiguing.
The two included batteries are standard capacity. Users with corner lots and larger trimming areas report cycling through both batteries during a session, and several have added a higher-capacity 20V MAX battery from other Black and Decker tools or purchased separately. Battery compatibility across the 20V MAX platform is a practical advantage if you're already in that ecosystem.
The EASYFEED line advance works reliably and draws consistent praise from users who have struggled with bump-feed systems on other trimmers. Edging performance is described as clean and controlled with the single wheel guide.
One long-term durability note drawn from extended use: the plastic trigger mechanism can wear over time and may eventually require disassembly and filing to restore smooth operation. This is a repair some users have completed successfully using guidance available on video platforms.

Frequently Asked Questions
Are Black and Decker 20V MAX batteries from other tools compatible with this trimmer?
Yes. The 20V MAX battery platform is shared across Black and Decker's cordless tool lineup, so any 20V MAX battery you own from a hedge trimmer, drill, or other tool will operate this trimmer. This also means you can purchase higher-capacity 20V MAX batteries separately to extend runtime beyond what the included standard-capacity batteries provide, which is useful on larger properties.
How does the 2-in-1 trimmer to edger conversion work?
The head of the trimmer rotates between the horizontal trimming position and the vertical edging position without requiring any tools. You release the pivot, rotate the cutting head 90 degrees, and the wheeled guide drops into position for edging along pavement. The wheel runs along the hard surface to maintain a consistent cutting depth as you walk the line. Rotating back to trimmer position follows the same process in reverse.
What should you do if the trigger becomes difficult to press over time?
The plastic trigger lever on this trimmer style can wear at the contact point after extended use, which makes it progressively harder to engage the motor. If you reach the point where the trigger will not activate the motor despite firm pressure, the repair involves disassembling the handle housing and filing the worn area of the lever smooth so it can travel far enough to actuate the internal switch.
Video guides for this specific repair are available for similar Black and Decker trimmer models. When reassembling, ensure the pivot spring is fully seated in its housing before closing the two halves of the unit.
