Aldi 20V Cordless String Trimmer
Aldi continues with yard and garden products for their Aldi Finds going into summer. The week of April 19th, 2023 you can pick up either this Ferrex Cordless Trimmer or the Ferrex Cordless Blower to keep your yard looking good.
This cordless string trimmer (aka weed wacker) will be available for just $49.99. It will work either as a trimmer or as an edger to keep your sidewalk and driveway edges clean.
This looks to be a different model or updated version compared to last year but the price has remained the same. I am not sure what specific changes were made but in the pictures below it seems like there were some changes. But those could just be cosmetic changes.
It uses the included 20V rechargeable battery to power the trimmer which may a little on the small side for some yards. Unfortunately Aldi doesn’t list the size of the battery for this year’s model. Last year’s model had a 1.5 Ah battery and I would expect it is the same or possibly bumped up a bit to a 2.0 Ah.
If you need a little more cutting power check out Aldi’s Ferrex Chainsaw! Yeah you read that right Aldi is selling a chainsaw.

Is the Ferrex Cordless Trimmer a Good Deal?
The Ferrex Trimmer/Edger will be selling for $49.99 which seems like a pretty good price for a cordless trimmer. The first thing to consider is this trimmer runs on a 20V battery which is on the smaller side. This string trimmer is probably best for a very small yard or for someone that needs a lighter trimmer and doesn’t mind stopping to recharge.
The other thing to consider is the lifetime of the battery. Since Ferrex is one of Aldi’s “Store Brands” (as far as I know) you probably won’t be able to go down to the local hardware store and find a replacement battery when the included one eventually dies.

All batteries like this will go bad at some point but with other brands you can generally find replacements pretty easily so the entire tool isn’t worthless. This does have a three year warranty and there should be some company that offers replacement parts and support so you should be able to get one, just with more effort. With other brands you can also get more tools that use the same batteries.
The Competition
If you have decided the 20V Trimmer is right for you let’s look at the price of the competition. I looked online for 20V Trimmer/Edgers that include a battery and charger and I found that most were $70-$100+ for a brand I recognized.
I also found this Power Smart String Trimmer on sale for a bit less. You can also find good deals on this Worx Trimmer if you keep your eyes open for good sales.
Probably the best deal I found was the Black and Decker Trimmer + Blower Bundle which includes 2 batteries and a charger. This is the option I would go with if I needed a small Trimmer/Edger and a Leaf Blower.
No products found.
It is more than buying both from Aldi but they have great reviedws and I know I can find replacement batteries and other parts pretty easy. If you only need the trimmer the Power Smart Trimmer could be an option for just more if you don’t want to go with the Ferrex Cordless Trimmer.
So the Ferrex Cordless Trimmer/Edger Looks like a good, but not great deal. If you want to save the money or just like buying at Aldi instead of online I’m sure you will get your money’s worth. But if you want something that more widely available I would give another of these brands a shot.
No products found.
If You Need Something a Bit Bigger
If you have a larger yard I recommend going with a 40V trimmer like this Ryobi I use. The 40V battery is generally going to last longer and the motor may have a bit more power. I also have a 40V Ryobi Leaf Blower that uses the same battery and charger. With that I can keep one battery charged up and swap as needed. There are other brands out there with similar batteries and specs but Ryobi is the one I have experience with.

Ferrex 20V Cordless Trimmer and Edger Reviews
Did the exit hole for the trimmer line have a bushing to preserve the line?
I’ve managed okay with this trimmer, although the line does NOT feed automatically (and I’m sorry others report no US customer service for replacing parts likely to wear out or get lost). But, on my trimmer, the hole through which line exits the spool to do the trimming has no bushing, so it is spinning line, with the resistance of grass and soil, rubbing against only the relatively soft plastic hole in the permanent housing (of the spool and line). Over time, the line has cut into that plastic hole and created the likes of two scissor blades that clip the line with hardly 30 seconds of use.
Did yours come with a bushing that perhaps mine has lost? I’ve spent more time in 2 hardware stores going through their marvelous collections and have settled on a brass fitting made to screw into wood furniture. The fitting has internal threads ready to receive screws. It is therefore like a brass tube, through which I have fed the line and now await the Gorilla glue I applied to bond the external-thread brass item better to the plastic hole. Fingers crossed. Let’s see if it will be the bushing needed. I fear these were manufactured without thought of line cutting into the plastic, over time, and thus without any bushing. I’d like to read anyone else’s experience.
Help! Can’t use our weed whacker
Our garage was put into disarray this winter when contractors came to make repairs from a flood. Now we can’t find our chargers for the weed whacker ANYwhere! Any suggestions where we can find a replacement?
Best investment I’ve made
This is the best tool for me. My lawn is average, not too thick and it does a great job. not to heavy and no cord to watch for. I have not had a problem with it in the 2 years using it. Would recommend it.
NO After sales Support
This thing could be really great. I mean, really. However, the battery charge is just long enough to complete my yard (not a bad thing, but I can’t immediately take it over the my mom’s house and help her yard).
There are no replacement spools of string available. Nothing at Walmart, Lowe’s, or Home Depot fits. The best thing you can do is go to Amazon and buy a roll of .050 replacement string, it will fit your spool, just make sure you wind it the correct way.
Lastly, my spool cover (the plastic squeeze cap) broke. I called the number on the back of the manual which took you to Merotec USA. I mentioned what I had, the guy on the phone said to go to forcetools.co. That was it. He wasn’t interested in helping any further. And this item is NOT on that website.
So, unless I can find a cap that fits, we’re out $50 and the company that makes it doesn’t give a crap about it.
Only worked twice
The trimmer worked only twice After that the trimmer would not work batter fully charged and trimmer does nothing Not a reliable product
