Runtime Extension Technology
BLACK+DECKER's Extended Runtime Technology features electronics that allow this trimmer/edger to maintain constant speed in a variety of grass conditions so the it runs at an efficient speed for extended battery life. In high-power mode, the LST420 ramps up the power output to quickly take down heavy grass and weeds. In runtime mode, the trimmer/edger provides up to one hour of runtime for normal trimming.
The LST420 comes with two 2.0 amp-hour lithium-ion batteries (model LBXR2020), which offers 33 percent more runtime per battery pack than the previous LBXR20 pack.
Trim in Comfort
Easy to start and quiet to operate, the LST420 cordless trimmer/edger weighs 5.7 pounds. Plus, it's fully adjustable so you can work at the ideal height, with pivoting handle positions to trim at odd angles in comfort and a telescoping pole that easily adjusts to a your preferred length.
This cordless trimmer/edger also features BLACK+DECKER's PowerDrive Transmission, which delivers consistent power in most grass types, helping to maintain cutting performance while trimming and edging in heavy grass or weeds. That ultra-efficient performance plus a generous 12-inch cutting swath help every job go faster.
With the LST420, you never have to bump to release the string or waste time continually adjusting the string spool. The BLACK+DECKER Automatic Feed Spool keeps the string at the optimal length automatically and continuously. The LST420 also converts from trimmer to an edger in seconds. A wheeled edge guide has been added for balance, helping to eliminate the need to hover the trimmer/edger over the line of grass between the lawn and sidewalk while edging. Simply roll along the sidewalk or driveway, and the wheel supports the weight of the trimmer/edger for a fine edge and straight, clean edges.
BLACK+DECKER's 20-volt MAX lithium-ion batteries offer a longer lifespan and retains its charge 5x longer than similar 18-volt NiCad batteries. They're compatible with the full line of BLACK+DECKER's 20-volt MAX line of power and gardening tools, and you won't be limited by an extension cord.
Easy to use and maneuver, the battery-powered timmer and edger eliminates the need for gas or oil to be stored.

Top Customer Reviews
Assembly: Assembly was real easy and consisted of pushing the plastic guard into a slot (1 screw) and attaching the D shaped handle (1 bolt).
Adjustments: The D shaped handle can be moved up and down the shaft, but the angle cannot be adjusted. The telescopic shaft can be shortened or lengthened. The distance between the center of the motor at the bottom of the shaft (center of the Black & Decker label on the motor) to the top of the handle can be adjusted from 36 inches to 49 inches. I'm 6 foot tall and it feels best fully extended for me.
Batteries and cutting line: Two 20 volt LBXR2020 Type 4 40 Wh batteries are included. The manual indicates that it takes five hours to fully charge one battery. The following LI-ION batteries can also be used: LBX20, LBXR20, LB2X4020. Use only 0.065 inch (1.65 mm) diameter round nylon monofilament line. B&D recommends the AF-100 spool: Black & Decker AF-100 String Trimmer Replacement Spool with 30 Feet of .065-Inch Line.
Warranty: 2 years for home use.
The LST420 works so good that my corded weedeater may just hang on the garage wall all summer long.
to the instructions.Have to say I was very impressed with the cutting power in #1 position and never had to use #2. I did my whole yard (15,00 s.f.) in about 30 minutes and still no slowdown on power at end. It's much lighter than my B&D corded electric so I didn't feel as though I'd been carrying an anvil around. I think the few that complained about the battery going down too soon when using, may be doing a lot of stop and start...much harder on batteries than just constantly holding the trigger down until job is complete. Considering Amazon's price was same as Walmart's and being delivered to my door free....it's a no brainer. Did I mention it comes w/ a 2 year warranty! Thanks B&D, you're on top of your game!
