A Little Background
Weeds and tall, unwanted grass have always been the major problem for every gardener or land and home owner. They often had so much hassle when it comes to trimming down everything to size and to keep the garden well-maintained. The manual way of cutting grass has been slowly replaced with technology, such as weed wackers or string trimmers.
These trimmers often come in either gas or electric form, with the gas powered one being the most common. A weed trimmer works with rotating strings that are designed to eliminate the grass and weed similar to a grass mower, but are more often used for weeds and garden maintenance.
With the new trend of the electric weed wackers, there is a question as to whether they are much better than their gas powered counterparts. Some say that electric and battery-operated ones give less carbon footprint and thus, are more environment-friendly when it comes down to it. However, some people who are more of traditional garden owners tend to still stick to their guns when it comes to weed trimmers and go for gas powered ones. In general, gas powered trimmers are good for big laws but if you only maintain a small suburban or metropolitan garden then an electric weed trimmer should do the trick – plus it lessens noise pollution and gas emission.
How We Picked
We picked the best weed wacker based from a series of criteria:
Is the battery long lasting, easy to charge and is the power equal to the maximum runtime of the weed trimmer? Having a Lithium Ion Max battery is perhaps the most recommended among all of the weed wackers that are electric powered, but when it comes to gas powered ones, the 4 cycle ones are the best when it comes to performance and stability.
Does the trimmer have enough flexibility and is it the right size for general users? Lightweight weed wackers are a big plus. The handle must be easy to grip so that you have better control over the weed trimming – design is everything when it comes to user comfort. The design of the weed trimmer also adds to its durability. Size also matters – electric powered weed wackers are usually supposed to be lightweight, compared to their gas powered counterparts.
Is the price worth the value of the product? You have to know if the price is well established for its different features. A weed trimmer usually ranges from $20 to $200, depending on its material and best use. Some trimmers are made for compact gardens and lawns while some are mostly gas powered ones, and are best used for large fields and hectares of land.
Do the reviews tell you more pros than cons? Take note of the reviews listed on Amazon, if they mostly tell you that the product has advantages rather than disadvantages. Take note of the score or rating – just because newer reviews are mostly bad doesn’t mean it’s that bad – you need to view more reviews to justify, since first impressions aren’t always what they are.
Can you easily choose and control the RPM? Variable speed weed wackers are the best to work with for easy adaptability on any situation. Different weeds have different thickness, and it all pretty much depends on your current situation, so you must have a variable speed control for your weed trimmer so that it can perform at its best even without wasting too much energy – especially for the electric weed wackers.
Switching between modes such as edging and trimming is important and should be done hassle free on the said weed wacker. You will need a reliable double purpose weed trimmer and edger with just a few simple operations that aren’t too complicated.
BLACK+DECKER LST136W 40V Max Lithium String Trimmer
For our best weed wacker, this smooth and stable machine runs on 40 V included Max lithium battery for longer lasting power and run time.
Being able to do continuous work, this weed wacker keeps away bumping due to its automatic feed spool designed to make your job easier. In addition, there is a switch between trimmer and edger mode using the shaft so you have a total control over your weed operation. Get your lawn or garden tidied up easier thanks to its quicker weed trimming using the PowerDrive transmission from motor to string.
You can easily control the speed to maximize your run time using its Power Command so that it will be able to operate at different conditions and thickness of weeds. Easily switch and choose between two modes using the Power Command dial: 8,500 RPM max power for use on thicker weeds, or a battery saver max runtime rate of 6,500 RPM.
Adding to that, power consumption is not a problem due to the fact that the 40 V battery can charge up to only 1 hour using the fast charger. With the trimmer also having a 0.065 line diameter, it holds a 180 degree rotatable head design. This rotatable head makes the weed wacker very convenient in tight spots where normal head designs don’t usually work, adding to its flexibility.
The BLACK+DECKER LST136W 40V Max Lithium String Trimmer weighs only 7.8 lbs, making it a very lightweight weed wacker. Generally, it is good for precision cutting due to its small, slim and ergonomic shape. As a whole, this weed trimmer also doesn’t necessarily spray a lot of particles compared to other brands so it is basically perfect for general purpose weed trimming. There is also an available variant in a cheaper, no-battery version. When you order the package, it includes the trimmer and edger itself, fast charger, spool (AF-100), 40 V Max Li-ion battery and a guard. This weed wacker comes with a 3 year warranty.
Who Else Likes It?
According to The Garden Tool Review , they praised the BLACK+DECKER LST136W 40V Max Lithium String Trimmer for its lightweight and usability features. The Power Command dial is said to be very efficient in switching between full power and max runtime – perfect for different tasks, whether minimal or on full blast. The cordless and fuel-less design makes this weed wacker a truly environmental-friendly product and convenient to use. The battery is also very quick to charge, the review says, which is significantly quicker than charging an iPhone. The review concludes that this weed wacker is a very comfortable machine to use and recommended for small garden owners.
Another review from Chainsaw Journal also states that the Power Command dial is the best thing in the machine, being able to switch between a power saver and a powered-up trimmer. It is also thoroughly praised for its great design features such as the automatic spool and the battery’s charging time and power.
Flaws but Not Dealbrakers
Unfortunately, much like other electric weed wackers, this is not for very thick bushes and for heavy duty power use. In addition to that, the battery can last only up to 1 hour for the max runtime mode (10 to 15 minutes on full power) compared to other heavy brands that have more than 1 hour runtime. It is only intended for use on small to medium sized gardens so if you want something for a big scale weed trimming then go for, perhaps, a gas powered weed wacker.
The BLACK+DECKER LCC140 40-volt Max String Trimmer and Sweeper Lithium Ion Combo Kit is our step-up pick. This heavy duty trimmer kit includes a 40 V max Li-ion battery for longer lasting operation at 2.0 Ahr.
With its great longer lasting power, the 40 V Max battery has a nominal voltage of 36 V and also compatible with other similar lithium tools, so you can use it for other weed wackers you may own. In addition, this tool is a 2 in 1 edger and cutter for convenient weed trimming along sidewalks. It comes with a 13 inch string trimmer as well as a sweeper so you can easily clear out debris and clean up the mess from trimming weeds.
Having a sturdy, light and powerful sweeper, it is carefully designed to easily clean up hard surfaces and similar places, so you get more value for the weed trimmer. This also has an automatic feed spool for continuous operation.
Charging won’t be a problem when it comes to this string trimmer because of the 90 minute charging time with its fast charger, which puts your problems to ease so you can have more time running the machine rather than charging it for a very long time. It also has a battery life indicator so you know when it is charging, fully charged and when it needs to be charged.
The combo kit’s sweeper runs at 120 MPH and only weighs 4.7 lbs, so it is a convenient and lightweight addition to your weed trimming operation. Worry no more about user comfort and flexibility because of the soft grip handle for the sweeper, which ensures that you are in total control.
You will have mostly no worries about leaves and debris getting stuck on the blow tube due to its scraper. The package, when you order the BLACK+DECKER LCC140 40-volt Max String Trimmer and Sweeper Lithium Ion Combo Kit, includes the trimmer, sweeper, battery and charger. It weighs 13.6 lbs, has overall dimensions of 13 in x 43.3 in x 7 in and is under a 3 year warranty.
