Black & Decker LST136B electric edger: Features 

As with the TORO 51831T electric edger, the standout feature of this tool is that it is cordless. This makes it extremely handy to use given that it’s not restricted at all, so you can get into even the furthest corners of your garden to give them a spruce up. It’s compatible with a 40-volt lithium-ion rechargeable battery (though this has to be purchased separately), which works to give you 45 minutes to an hour of run time. 

Due to its battery-powered nature, this machine is quiet to run so you won’t be disturbing your neighbors as you tend to your lawn. It’s also equipped with a PowerCommand dial, which allows you to choose whether you want to max out on power or save your battery for a longer running time. Another feature that aims to make your life easier is the automatic feed spool which ensures your tool is working continuously, so you don’t have to stop and make adjustments midway through the task. 

You can convert this tool from an edger to a trimmer with just a quick turn of the machine’s shaft, and get more functionality to tidy up your garden with. Unfortunately, despite its versatility, a downfall of this edger is that the batteries and charger are sold separately to the main unit. That means the initial cost price is a lot higher than it first seems, and means you’ll have to make sure to bolt them onto your overall purchase. However inconvenient this may seem, this tool should be cost-effective in the long run thanks to its battery and will allow you the freedom of going wherever you like with it. The blow is also softened by the excellent warranty that comes along with this edger, which covers three years.

Black & Decker LST136B: User reviews 

The Black & Decker LST136B electric lawn edger has a 4.5-star rating out of five on Home Depot, a score gathered from 1,768 reviews. 91% of those who reviewed this edger said they would recommend it, which is a strong testament to its abilities. 

Glowing reviews for the Black & Decker LST136B mentioned the ease of assembly and excellent value for money of this tool. Others were impressed by the PowerCommand dial, with one reviewer saying: “I like the power settings so that you can run it to conserve power but also have the capability of clearing difficult weeds”. Another added that this is the “best string trimmer” they have ever owned, and allows them to “edge sidewalks and flower beds, and trim bushes as well”. 

Some reviewers spoke of a slight learning curve when getting to grips with this edger. One said it took some time to work out they “Had to hold two” buttons together at the same time in order for it to work”, whilst another said that it’s worth watching videos on how to operate the product before you dive in.

Should you buy the Black & Decker LST136B electric edger? 

The Black & Decker LST136B is a great tool for getting your garden into shape, and won’t break the bank either. Besides the fact that you need to buy the battery and the charger separately, it’s a worthy investment given its dual functionality and feature that allows you to either max out on power or run time. 

Given the battery-powered nature of this model, it is best suited to small or medium-sized gardens. If you need something that won’t ever have the issue of running out of charge, then the WORX WG896 might be best for you.
