Product Details

The BLACK+DECKER LST400 12in High Performance String Trimmer/Edger. With up to 1 hour runtime**, this lightweight trimmer/edger gets the job done with maximum comfort and control. It is quiet and easy to start, delivering great cutting results without the mess and hassles of gas powered trimmers. The Trimmer/Edger easily converts from a Trimmer to an Edger in seconds. A wheeled edge guide has been added for balance and 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. In a significant step forward in string trimmer technology, the Lithium High Performance Trimmer/Edger features a dual-mode switch, which provides the options of choosing high power or extended run time for trimming large yards without the hassles of gas-powered trimmer/edgers. In high-power mode, the Trimmer/Edger 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. BLACK+DECKER?S patented Automatic Feed Spool AFS advances the trimming line with no bumping required. The Trimmer/Edger comes complete with a pre-wound 30-foot spool. A critical component that enhances the Trimmer/Edger?s cutting power is BLACK+DECKER?S patented POWERDRIVE Transmission, which delivers consistent power in most grass types, helping to maintain cutting performance while trimming and edging in heavy grass or weeds.

20 volt max Lithium Use for trimming areas of overgrowth after mowing and to edge around borders, sidewalks and flowerbeds Easy converts from trimmer to edger Pivoting handle and adjustable length Powerdrive transmission Automatic feed spool Runtime extender technology Patented gear drive transmission Maintains constant speed won't slow down during trimming 12"

I love this weedwacker! It is so light to I can easily use it for as long as it takes to get the job done. The "mower" attachment is great for larger patches that I still can't get with my riding mower. I can get 15 minutes working time from each battery included. I recently bought an additional larger battery and that gives me 30 minutes. It is high powered and does the job without using gas. It is easy to use. I simply love this tool!

I like this product. I have used as trimmer and edger, but the reason I bought was the mower attachment. I have a small hill and my regular mower is hard to use on. This solved the problem. Battery Good 15 to 20 minutes, did buy a fast charger to work longer. Trimmer works well!

I needed a weed trimmer for light duty and did not want to use a petroleum based trimmer and after reading multiple reviews I decided on LST400. it easily cuts through all of my weeds along my fence and house. it also does a good job of edging my driveway. the one hour charge is sufficient for me as I like to take brakes and work on other things so waiting 30 min for it to charge is fine by me. (I have the quick charging station and it works great!) the over all feel of the device is it is not like holding the Heavy powerhouse gas trimers which can leave your arms feeling as they are going to fall off in just 30mins of use. it does not come with a shoulder strap or harness but honestly it does not need one as it is light in weight and meant for light duty.

I've been using the weed eater for a month now, and it's tackled every job I've done. With the battery fully charged, I can work for over two hours, and I don't notice any loss in power regardless of the type of weeds I'm cutting.
