And it speeds your work by feeding trimmer line without bumping, and by quickly converting from grass trimmer to electric edgers for lawn.

Review: Great Product - Exactly as described very powerful. The only complaint I have is it's very difficult to connect the battery to the base charger to charge you have to finagle with it quite a bit to get it just right. Kind of a pain. Other than than it works great.
Review: This is the one! - Got it in the mail today just in time for my weekly mowing. I had bought Brand new and dumped a Greenworks duel string trimmer two weeks ago that jammed about 6 times in 30 minutes. I unpackaged this B&D today charged the battery while I mowed. Charges a little slow it was only 1/3 full after an hour or so. I put it in the trimmer with only 1/3 battery life and proceeded to trim through my half acre lawn edges without running out of battery and with zero jamming. It was a tremendous experience. I love this thing! Imagine what it can do on a full charge. Will it work for a farmer who’s mowing down alfalfa? Probably not but for the homeowner who just needs to make his yard look nice this is the one! I agree with some other reviews that is could be a little taller (6-12”), and the battery takes a while to charge but that’s a small price to pay for such a durable well designed trimmer that gets the job done so quickly and without any hassle. Handle is super grippy, auto feed is great, Lightweight, 40v is plenty of power, no cords to deal with, etc. Five stars!

## Questions & Answers

**Q: What's the difference between this 140c model and the current lst136 model? autofeed?**
A: There is actually not much difference between the two.  By the way, the LST136 is a discontinued model, while the LST140C is a current model...I think it just came out this year.They both have the same autofeed, and use the same spool, and of course, the same size line.  The LST136 will pull 40v at max power, and 36v at normal/lower power...I noticed that someone has claimed that the LST140C is just on/off, but pages six and twelve of the manual says it's a variable speed control.  I experimented a little, and it appears that the trigger's range of motion between off and full power is very, very short, as opposed to the LST136 (I really hate the bastard who stole mine--I'd either have to spend a lot more, or travel to another city to get another).  I just now checked the B&D website to see what they say, and the LST136 is supposed to spin at 6500-8500 rpm, while the LST140C is supposed to be just 6500 rpm.  Either their manual is wrong, or their website...take your pick.The LST136 uses the LBXR36 battery pack, and the LST140C uses the LBX1540...but aside from minor style differences (including rubber on the bottom of the LBXR36), and the LBX1540 having a three level charge indicator vs. the four that the LBXR36 has, they are identical, including charge/use time.  They are interchangable, which is the very first thing I tried out, once I'd put my 140C together.  By the way, that battery has been off the charger for about a year, give or take a few months, and it appears to still have a full charge on it...awesome!My LST136 came with the fast charger, and the LST140C I just bought came with a slow charger, which is likely part of why the LST140C is cheaper.  The fast charger is a lot bigger...the battery fits into it, while the slow charger is a little thing that clips onto the terminals.On the LST140C, the plastic runs around a foot further down the shaft, with the handle snapping onto a pair of spring-loaded buttons, one of which has indentations which lock the position of the handle...a great improvement over the handle design of the LST136.  The handle on the LST136, if I recall correctly, can be moved up and down the shaft, and can easily be accidentally turned out of line with the control switch, which isn't all that helpful.  Also, the LST140C's length adjustment is mounted on the lower end of the plastic, as opposed to being somewhere between the handle and the head.If there is any difference between in the head/guard, it isn't much at all.I wish the LST140C's switch had a bit more play, but I suspect it won't really matter overall.

**Q: Does this one come with the high speed charger? or the regular one? how long does it take to charge?**
A: Regular charger I believe.  For me it seems to take about three hours to recharge.  I have two because I also bought a hedge trimmer.  They seem to last about 25 minutes each, which is more than I can last.

**Q: Do you have to stop every 5 minutes and re-adjust the line feed on this model?**
A: yes - my LST136 will not autofeed with the newer slightly different version of AF100 spools that lack the chamfered spindle hole, old 18v model still autofeeds a champ with same spools

**Q: Hello, is this the 20v or 40v battery?  I only ask because others are saying 20v:/**
A: My trimmer came with a 40V battery. I also bought the extra 2.5 ah 40V battery and 3 spools of line. I'm very happy with the purchase.

### ⭐⭐⭐⭐ Great Weed Trimmer...But plan on buying new batteries!
*by J***. on August 23, 2023*

Great light weight trimmer and it was quiet compared to my old Worx. 2 features that I really miss from my Worx that would make this trimmer fantastic.... add wheels so that you can trim under bushes and other things in your yard that cannot be moved. and the battery...awful! 40V doesnt mean anything with out the battery amp hours and the battery they include only has 1.5ah which gave me 15 minutes of use... and my battery was fully charged overnight. my worx battery was a 40V 4.0ah and it lasted almost an hour...big difference! I missed that on the specification page when I was ordering a new trimmer. If you are wondering why I just didnt order another Worx trimmer, I did and had to return it. They have totally cheaped out on their product durability and it was broken when I opened the box. I saw other possible areas on the worx trimmer that would break easy too. my old worx trimmer was made with more durable material and lasted almost 8 years; so I thought I would give this black decker trimmer a try. I think this trimmer works great but i think black+decker needs to treat their customers better and give them a quality battery as well...not this worthless one that is included with the trimmer. and by the way the charger is very cheap too and hard to get the battery on and off.
