Offering Black & Decker's exclusive PowerDrive Transmission, the 12-Inch cordless GrassHog LST220 trimmer and edger delivers more power from the motor to the cutting string so you can get the job done faster. You'll be able to trim grass in hard-to-reach areas where mowers cannot cut while also maintaining a neat edging along hard surfaces.
 Two 20-volt batteries for longer run time and better access to remote property areas (see larger image). |  Cut the extension cord and enjoy a long charge with the 20-volt lithium-ion battery (see larger image). |  Switch from trimming to edging in seconds (see larger image). |
It's powered by a 20-volt Max lithium-ion battery that offers a longer lifespan and retains its charge 5x longer than Black & Decker's 18-volt NiCad batteries--and this package includes two batteries so you can keep one charged while using the other. The battery is also designed with 50 percent less battery weight, and the unit weighs a total of 5.2 pounds with battery installed.
It features a Groom'N'Edge head that can be rotated 180-degrees for quick switches between cutting and edging tasks along with Black & Decker's Automatic Feed Spool (AFS) system, which uses centrifugal force to dispense more line whenever you need it for added predictability and dependability--no bumping required. Other features include a telescoping pole that easily adjusts to your preferred height, flip-down edge guide, 7500 RPM motor, and 0.065 line diameter.
The included Energy Star-qualified charger will charge a fully depleted battery in about 8 hours. You can also swap the battery among your other Black & Decker cordless lawn tools that are compatible with 20-volt Max lithium-ion batteries. It's backed by a two-year limited warranty.

This review is from: Black & Decker LST220 12-Inch 20-Volt Lithium-Ion Cordless GrassHog Trimmer/Edger (Lawn & Patio)
Over the years I've used many Black & Decker products. Everything from power tools to lawn care equipment, most are as advertised and effectively do the job just as good as the higher priced competition. I haven't used a gas powered tool in over 12 years now. I've also gone the electric route as well. My eleven year old 18 volt B&D trimmer has more then proved itself and finally was put out to pasture. I'm still surprised that I got that much running time from the two 18 volt batteries that came with the unit. For quick and easy trimming, its been a capable tool. That said, I picked up the Black & Decker LST220 Grasshog Trimmer at my local hardware store last weekend.
After a quick inventory, I scanned over the brief instructions. Its pretty much cut and dry as to what's in the box. There's the trimmer, instructions, two batteries, cord, and a charger. The company also tags on a two year limited warranty. The instructions on Black & Decker tools are still amusing to say the least. It doesn't take a degree in rocket science to put a piece of their gear together. Knowing what I know about battery powered lawn tools, I knew I would need both batteries to complete the tasks in my large front and back yards. So I charged both of the 20 volt batteries for about 8 hours each. Now the test. First off, the B&D LST220 Trimmer has a nice light feel to it. Like my older trimmer, the handle has a good ergonomic feel to it. It easily moves up and down and rotates a full 360 degrees. Adjustment is easy. It didn't take me long to find out about the line's new auto feed system. Its much nicer then the old bump and feed system. On average I found myself using about four of the 30' line spools a year. Only time will tell if that number drops with this new system. The trimmer does seem faster. I don't doubt the advertised 7500 rpm a bit. The 12" trim path has not changed from my older model. The trigger configuration hasn't changed either. Its still has a nice feel. Trimming wise, this model operates smoothly without any hiccups. It does a great job of getting under bushes and around the fence line. Just like my older unit, I was not surprised that I had to utilize both batteries to get the front yard trimming done. I noticed a drop off in power at about 15 minutes. Good thing B&D includes two batteries. One battery doesn't come anywhere near getting the job done. The metal guard for edging has stayed much the same design as the original model. Like my older B&D trimmers, the LST220 Trimmer is not capable of doing a great job of edging because of the steady drain on battery power. Even with two 20 volt batteries, its just not enough juice. I always have to break out my electric powered edger or hand tools to complete the task. Why Black & Decker even promotes its lineup of battery powered trimmers as edgers is a mystery to me. Even though I am user of many Black & Decker products, I find the company's website limited on up to date product information. Product registration is available via the site. It seems that it took them ages to post a toll free number. Now depending on the product, there is a toll free number posted for each line. When I did contact customer service for other tools that I've owned, I've always received outstanding service. Signing up for the company newsletter via email is nothing more then receiving an occasion survey on products. Even with its battery limitations, the Black & Decker LST220 Cordless Grass Hog Trimmer is a useful working tool in clearing out ground not accessible by a mower. When it comes to edging that's a different story. Personally I don't think there is any battery powered tool out there that certifies as a true edging tool. I know I've not seen or used one. Still, this Black & Decker tool covers the bases as a good gas free trimmer.

Amazon Verified Purchase(What's this?)
This review is from: Black & Decker LST220 12-Inch 20-Volt Lithium-Ion Cordless GrassHog Trimmer/Edger (Lawn & Patio)
This is my first cordless electric trimmer. Despite of mediocre reviews at consumer reports I decided to try this one, after yet another half hour on my knees in the garage trying to start my diva-esque 3-year-old 2-cycle gas engine trimmer..
Shipping was slow, packing the worst I've ever seen from Amazon! But it worked, and it was fairly easy to put the parts together. I used it twice now, so here is my impression: Sleek looks, length is adjustable (but barely enough for me, and I am only 6ft tall), charging really takes 8 hours for each battery (!), and the trimmer runs between 10 and 12 minutes with a fully charged battery - less if you are edging stubborn St Augustine grass. It is louder than I expected, but still much better than a gas engine trimmer. Trimming: The line is a little thinner (.65) compared to my Ryobi gas trimmer (.80), the diameter of the cutting area is a lot smaller and it uses only one line instead of two, so it takes a little longer to trim the same area. But it still works fine on a regular size suburban lot like mine. I did not find anything that this trimmer would not 'mowe down', so this is a success! It takes a little more time, but the lower weight, noise and aggravation level are making up for it. No more mixing gas and oil and fiddling with starters.. Edging: The Black&Decker is too weak, at least for edging the stubborn crawling shoots of our Floridian St Augustine grass. It still works, but I have to carry a manual pruning cutter with me and walk the edged line again to cut the remaining grass by hand.. I am not sure if the line is too soft or too thin or whether it is just the lack of power or rotation speed, all I can say is it cannot compare to a good gas powered edger. The batteries are gone fast too, when you are edging. That's a disappoinment. Since this unit is very light weight and the batteries are small, it makes you wonder why they didn't double the battery size/capacity? It would still be very small and light weight.. All in all a really nice tool for a suburban lot, and good enough if you are willing to add some manual work here and there.. I consider trying the cordless lithium-ion leaf blower, but since that one comes only with one battery, I am worried it may work only a few minutes - waiting for your reviews!

LIGHTWEIGHT BUT SHORT RUN TIME,
This review is from: Black & Decker LST220 12-Inch 20-Volt Lithium-Ion Cordless GrassHog Trimmer/Edger (Lawn & Patio)
I bought this product from my local "bigbox" store a month ago so thought I would drop a review here anyway. The LST220 came with two 20volt lithium ion batteries, a charger, and a leaf blower. I am not the least big mechanically inclined, but I put this wonder together in a few minutes. Batteries each take a full 8 hours to charge, which is a drawback for me, since they only gave me 20 minutes of weeding on each battery, and take 8 hours to charge each one. This unit's height can be adjusted with the quick easy turn of a collar, and the (.065) line is automatic--so no more bump & feed! It is so lightweight and easy to use, and I really do love the fact that I don't have to mess with pulling that nasty string a dozen times on a smelly gas-powered trimmer any more. With this model, all you do is push a button! The only cons would be that the battery lasts me 20 minutes of run time, so I get to do about 35-40 minutes total weed whacking using two batteries. Quite honestly, I can't stand doing much more than that anyway, but I called B&D to verify this, and was told that 20 minutes' run time is the best that I can expect to get for each battery. When I asked B&D why they don't make one with a longer battery life (an hour per battery would be good) I was told that it would make the unit much too heavy (huh??). An electric (corded) weed trimmer is not an option for me since I would have to have an 800ft. cord. I gave it 4 stars instead of 5 only because of the short battery use; a quicker charge time would be a plus. Otherwise, I really enjoy using it, so much so that I think I'm addicted. Haven't had to change the spool yet, but will update this when I do.
UPDATE: By the time I had used this 12-14 times, I was only getting 7-10 minutes' run time from each battery. With 16+ hours charge time, it would take me 3-4 days to complete one small area. It's a shame really, as everything else about this machine is great. B&D told me not to expect more than 7 minutes of use from each battery. I ended up returning this weed whacker, and still looking for a good cordless. For those of you who claim to get 35+ minutes' continuous run time from each battery, I'd like to know how.
