Best Overall String Trimmer: Black+Decker 40V MAX 13 inch

As I mentioned in our best overall string trimmer review, I own this weed wacker model. I have an entire line of Black+Decker outdoor power equipment – the lawnmower, leaf blower, and string trimmer. All of them are the 40V MAX models, so I can keep charged batteries going at all times.

Both my wife and I like this trimmer. It’s a push-button start.  It’s maneuverable, has an adjustable shaft and handle, and isn’t very heavy at all.  My guess is, all in (including the 1.5AH battery) it weighs in around 8 pounds.  I don’t often use the lawn trimmer and edger feature, but it is there when you need it and is pretty simple to use.  It’s really quiet as well – you won’t need to worry about you or your loved one damaging their hearing when using this string trimmer.

Getting more line while working is really easy. It comes with an automatic feed spool (AFS) technology – that just means the trimmer line is automatically released as needed. No bumping is needed. I use Black+Decker spools and string since it’s cheap. Like many cordless string trimmers, this model uses 0.065-inch line diameter string.

Is it the strongest model of all the cordless trimmers available? No. But I don’t let my yard get overrun with weeds like the Maginot Line either. The 13 in wide cutting radius is plenty for working in the yard or around the patio. Most homeowners should be happy owning this grass trimmer model.

The BLACK+DECKER LSTE525 trimmer edger has everything you need to rid your lawn of those pesky weeds. Its electric PowerDrive Transmission is one of the best in its class. It’s powerful enough to get the job done, yet easy enough to handle.

Runtime Extension Technology

The Runtime Extension technology allows you to switch between longer run times, or more power. The switch will either boost power for tougher weeds. Or, you can set it to conserve life on the battery.

20 Volt Max Lithium Battery

This weed eater comes with one or two 20 volt Max Lithium batteries that deliver long lasting, powerful cuts. You’ll also get a charger and a spool of string. The battery system is part of the 20 volt Max battery family of BLACK+DECKER tools. This means one battery will fit every BLACK+DECKER tool that uses this battery. I’d opt for a package with an extra battery – it’s handy to have one fully charged while working on the lawn.

Automatic Spool Feed

Other great features on this string trimmer include an automatic spool feed that will always provide enough string for continuous cutting. A 12 inch cutting radius that cuts down on the time needed to weed eat. You will also be pleased to know that the rotating head allows for easy edging with its guided wheels for a perfect looking edge cut every time.

This is one of the most versatile, yet easy to use straight shaft electric weed eaters on the market. Weighing under 7 lbs. the BLACK+DECKER LSTE525 is easy enough for anyone to use while still providing a powerful cut.

The Grass Hog line of BLACK+DECKER products has been a popular choice of home owners for years to maintain their yards. B+D has clearly decided to go with the MAX lineup of batteries – so it’s nearly impossible to find products that work with the Grass Hog.

If you are looking for a solid replacement for your aging Hog, the LST300 is a good choice. It’s an inexpensive way to upgrade into the MAX lineup of batteries.

Lightweight & User Friendly Design

The LST300 string trimmer features a lightweight, user friendly design with plenty of power. Its 20 volt MAX lithium ion battery packs power and a long life for most tough jobs around the house. At under 6 pounds in total weight, this model is one of the more powerful in its class.

This trimmer is one of the most user friendly ones around. It’s easy to start, very lightweight and requires little know how to get a perfect cut every time. The automatic feed spool aids in operation by never having to bump the trimmer head to get more string.

Long Battery Life

Its long battery life and 12 inch swath mean you can get done the job faster so you can go back to enjoying your day.

Easily Convert to an Edger

To top it off, the BLACK+DECKER LST300 weed eater easily converts from a string trimmer to an edger in seconds. Go from trimming to edging at the push of a button to put that final touch on your yard and make it look like a professional cut.

Overall, the BLACK+DECKER LST300 is a great option for home owners with a small to medium sized yard. Its versatility makes it one of the best in class of cordless weed eaters and edger’s. It’s easy to use, has a long battery life and will get the job done quickly.

Best Corded B+D String Trimmer: BESTA510 14 inch

We like BESTA510 14 inch

If you can put up with using an extension cord – and have an outlet close enough to use in your yard – then corded electric weed eaters are an outstanding value. They are nearly always less expensive than other trimmers and provide a great deal of power. That’s the case with our pick – the Black+Decker BESTA510.

Very Lightweight

The BLACK+DECKER BESTA510 is another lightweight and easy to use corded electric weed eater. Don’t let its small and compact size fool you though. Its 6.5 amp motor produces high torque for maximum performance. Add in the PowerDrive transmission that prevents it from bogging down in those thick weed areas; you have one of the more powerful electric trimmer’s in its class.

Adjustable Handle

This trimmer is one of the easiest to use in the class. The handle is adjustable height for your comfort. You’ll want to make sure the weed eater is at the right height when working on the toughest weeds in hard to reach areas. With a 14 inch cutting area, you can cover plenty of grass in a short amount of time.

Auto Feed Spool

To keep you trimming, the auto-feed spool always makes sure you have enough string to keep cutting without having to bump the line or stop working. And in just seconds, the 14-inch trimmer head will rotate for edging. The guided wheels will ensure a nice cut as well.

Packed with features and coming in at a very low price; the BLACK+DECKER BESTA510 is a solid choice for smaller yards that can still tackle tough weeds.

Best Edger – Trencher: Black+Decker LE750

We like Black+Decker LE750

Weed eating is just half the job when it comes to having a professional-looking yard. If you already own a standard trimmer, you know how difficult it can be to flip it upside down and try to edge your pathways. The BLACK+DECKER LE750 will solve this problem.

Perfect Looking Edge

It’s a trimmer edger and landscape trencher combo that will give a perfect-looking edge. And with the flip of a button, create new landscaping paths with ease. The wheeled edge guide helps keep your cuts straight and true around flower beds and sidewalks.

Its powerful 11 amp motor has more than enough power to do exactly what you need. It has a max torque of 150 in. /lbs. and 4,700 RPM’s.

Great For Low Voltage Wire Trenching

This power tool shines when you need to bury some 12v wire in your yard – maybe to power some landscape lights. Instead of having to hand trench, you can convert the LE750 into a 1 to 1.5 inch trencher. It’d be good for putting in an invisible pet fence or setting up your boundaries for a robotic mower as well.

True Ergonomic Use

Once you receive the edger, it snaps together in seconds with no tools necessary. Operating it is just as easy with its push button start and adjustable handle. There is even a left handed assist for true ergonomic use.

This edger and trencher in one is a superior product that will be all you need to have your yard looking like you just paid hundreds or thousands of dollars for it. At a low price point, its value is unheard of with all that you get in the BLACK+DECKER LE750.

  12. Complete nonsense all of it including the comments, plastic gears!!!

  14. Mine comes to the rescue when the gas equipment will not work. Just as powerful for tough large weeds ad a gas unit but yet feeds without fault, never winds up weeds, it is great, so long as the cord reaches. I got the cord wrapped around it and guess what? The cord ended up in the cord catcher! Well thought out design.
