Gardenline Cordless Trimmer (Ferrex Cordless Trimmer / Edger)

Last Updated on April 3, 2024

EDITOR’S NOTE 1: A number of people have asked us about where to find replacement line. The Gardenline trimmer uses a 0.055 inch (1.4 mm) line, which is not a common size in the United States (although it does seem more common overseas). Most hardware stores don’t carry line in this size, which can be frustrating for consumers. 

When we reached out to the trimmer manufacturer, Sumec North America, they referred us to the replacement trimmer line available on its website (as of 2022, the link appears now broken). Note, though, the shipping costs are very high unless you buy in bulk. You may also be able to find the trimmer line other places online.

EDITOR’S NOTE 2: Aldi now sells its lawn equipment under the Ferrex private label. Aldi seems to be using some of the same suppliers, though, so our review of the Gardenline trimmer may also apply to the Ferrex one. The Ferrex 20V Cordless Trimmer/Edger cost $39.99 at Aldi in April of 2024.

I purchased the Gardenline 20 Volt Cordless Trimmer (manual) in April 2018. I’ve been needing to replace a gas-powered string trimmer that had died the previous year. I’d been looking at electric trimmers since then, but I have been wary of their price. Aldi moved Gardenline products to the floor and the trimmer was priced at $40, so I figured it was worth the shot. [EDITOR’S NOTE: The 2018 trimmer also comes with a 2-year warranty.]

Unboxing the trimmer was rather uneventful. It is a lot lighter than anticipated (~10-15 lbs.; no official weight found). It comes assembled with the exception of the shield and battery. The shield clips on without effort. The battery and charger were in their own boxes, but they are equally easy to get working together. I plugged the battery in to charge and unplugged it the next morning.

The trimmer seemed short, but no worries; it’s on a telescoping pole, so you can adjust the height. It feels like something is in the pole to assist the retraction, but it does not stop the ease of extending the height of the trimmer. The mechanic also doesn’t make noise inside the aluminum pole. The handle has a wingnut and bolt that allow the user to change the angle when holding the trimmer, while the green handle at the top holds the battery pack. The other end has a push button to change the angle of the trimmer head, as well as a switch that allows the trimmer head to rotate.

Using the trimmer was equally easy and uneventful. Popping the battery into the handle, I walked up the driveway, pressed the thumb switch, and pulled the trigger, and it started to spin. I did not feel the torque I was used to from the gas-powered string trimmer, so I was a little concerned. But when I held it to the height I wanted, it easily cut the blades of grass to the height I wanted. (An unexpected surprise to me was how being able to change the neck and head of the trimmer made the work much easier.) I got to the end of the line, stopped, took my finger off the trigger, rotated the head, and used the wheel to walk the trimmer to edge along the sidewalk. It was quick, easy, and painless.

I moved along the rest of the yard. Due to how long it had been since I last trimmed, I had to give more attention to some areas than others. The trimmer seemed to stop working after about 30-40 minutes of continuous work, getting me to the front of the house. I’m not going to pretend it has the power to cut brush, but it did cut through some hardy ivy that was moving off my stone wall onto the driveway. After the battery was empty, I set it to charge, and I mowed the lawn. After mowing the lawn (about 1 to 1.5 hours) I checked the battery and it had not fully charged. I grabbed the battery pack the next day and did the back yard.

… and after. (Click to enlarge)

I believe I made the trimmer do heavy work due to the lack of trimming done over the past year. I think next week’s touch ups will be completed on one charge. I like the result in the yard.

The Verdict:

On the positive side, this trimmer is quick, easy, and intuitive to use, with a lightweight build and no fuss. On the negative side, the battery takes a long time to recharge and there is no secondary battery (unless you have a battery from another Gardenline product). Overall, at this point in time, I would buy this product again. I would also refer this product to a friend, or gift this product to my elderly parents.

  1. Hi. I bought the trimmer and I am impressed with the product for the price. But I am running out of line and I can’t find where to buy replacement line, 0.055″ or 1.4 mm. Or even a spool if I have to. Do you have any suggestions? Thanks.

    • We’ve updated our post with what we know.

    • If you have an ORiley autoparts store near you get them to order the prime Line round cut trimmer line 0.050 diameter. It works in the ALDI Gardenline Cordless Trimmer. Just bought it and used it this morning. I hope this helps.

      • Would you happen to have the O’Reilly’s part or item number? I searched for Prime Line round cut trimmer line 0.050 diameter and that size doesn’t show up. Any help would be greatly appreciated.

    • rue ann olmstead

      I never even thought about buying replacement line.
      I just shoved in .080 “weed eater) from my 2000 ft. role I bought years ago.
      I used it all last year, and the only downside, might be that I only get about as much time out of my battery(compared to this review).
      Works great, and….. I can chop down small brush, and big weeds.

      • Need a battery charger mine was misplaced have looked at Walmart Home Depot Lowe’s battery plus advanced auto oreilley auto parts!

    • I have one of these trimmers also that a friend gave me-but cannot find any line for it anywhere–any suggestions where to get some line for it

    • I lost my battery need a new one where can I get one ?

  2. I’m having the same problem. Can’t get an extra battery or string. The one site that advertised the string cartridges seems to be involved in scams. I bought my first unit from the previous owner of my home, then bought a second thinking I could get string and that I would have a second battery. Turns out that even though the Aldi part number is the same (52646), the batteries are not compatible and both are the 20v models. I would not recommend buying this – you can’t get supplies or parts in this country. I don’t understand why an international firm would sell a product it can’t support.

    • I am returning my Gardenline trimmer from Aldi. Very, very disappointing. Bought it two weeks ago. I cannot find any .055 string replacement (I went to Home Depot, Sears, and Ace Hardware). DON’T BUY THE ALDI Gardenline Trimmer!

      • I have the Ferrex 20V Trimmer/Edger I bought from Aldi, in the User Manual it said the replacement string diameter is .065 (1.65mm). It is readily available at Home Depot and other online stores.

      • I read the manual that came with the Ferrex wireless Trimmer/Edger I bought from Aldi 6 months ago. It said it uses a .065 line which is readily available at Home Depot. I already have a .065 roll I used for my old Black & Decker trimmer and it worked fine.

        I wanted extra batteries for my Ferrex Trimmer/Edger and Blower to extend the usage time but no replacement batteries are available according to the customer service I called from the phone number in the user manual.

      • If you have the 20 Volt Ferrex battery with 3 slots and a hole in the middle of the battery, Amazon has a charger that works. It is a “SuperHandy Charger 20 volt charger. Sold by SuperHandy and Supplied by SuperHandy. Works great for my Aldi Ferrex battery. Also, The SuperHandy (GUT051) battery will [probably work as a replacement battery.

      • Right! I have been to the same places cannot find any line for it! And a friend gave me the trimmer! Do not buy any weed trimmers at Aldi’s

    • Lowes bro………….

  3. Hey Josh,
    Any idea where to get the string for this trimmer?

    • I’ve updated the post (see the top) with what I know. I’ll update it further as I learn more.

    • If you have an ORiley autoparts store near you get them to order the prime Line round cut trimmer line 0.050 diameter. It works in the ALDI Gardenline Cordless Trimmer. Just bought it and used it this morning. I hope this helps.

  4. The link to the website above to purchase the replacement trimmer line is broken. The replacement parts for the trimmer are being handled by As of this writing, the replacement batteries are on back order and can be purchased at that site when the arrive.

    On my trimmer, the China man who wound my line spool, wound it too tight and kinked the line, so I have lots of experience with the line spool. I finally removed all the original trimmer line and replaced it with .065″ diameter line I bought at that huge blue home improvement store that begins with the letter “L”.

    I paid $10 for 200 foot of line and the difference in size is only about .20 mm. The machine will never know the difference and it worked perfect for me.

    Do yourself a favor and buy the cheap .065″ line and rewind it yourself. It’s so easy. There’s even an arrow to help with the direction. Then wait for the batteries to pop up on the web site and get one of those too, if you need it for bigger jobs.

    • I went to a store and bought the skinniest .065 wound it like a sewing bobbin carefully and tight it works fine if wound right

      Im conserned it is so loud can I put a drop of oil any where??

    • I’m looking for the garden line replacement battery, you mentioned a website, what site can I go to order a battery?


    This site sells this replacement line for $5.99, but the only shopping option is $7.10 priority mail.

  6. it can be bought on line for 6 bucks but the shipping is 2 day only and costs 8 bucks

  7. Bought it at Aldi’s at the beginning of summer. For the price, it’s excellent. I’ve had inexpensive black and decker trimmers in the past and this one works as good or better. Just now running out of line and found this site. Susan’s link above is good source. I like David’s suggestion for .65mm line. I will try that. Great review Joshua!


    • “WORX WA0010 5 pack Replacement Spool Line with cap” on eBay less than $10.00 it fits perfectly for my Gardenline trimmer model # 52646.

  9. This company sells Garden Line supplies. The replacement string spool is out of stock. I have seen some others on Ebay but not sure if they fit this specific model.
    I really like this trimmer, it is the second one we bought since my husband misplaced the battery charge for the first one we bought in 2017. It is lightweight and easy for me to handle. My husband has muscular dystrophy with weakness in his hands and this one is easy for him to use as well.

  10. you can use heavy line, trim the line to a point to get it start on reel it will last longer

  11. I ordered a second battery from the Sumec (Force Power Equipment) website. When I opened the box, I found a broken battery inside (the outercase was open and I could not close it again because the holes for the screws had broken off). I contacted Sumec first by mail > no answer. Then I called them, they found back my mail and promised to follow up > no reply. I called them again and finally they sent me a new battery. This time it was not broken when it arrived … but it showed the same problem after 4 or 5 uses. I contacted Sumec again … 3 times > no answer. Final result: I have one working battery (the original one) and 2 broken ones. I can not trim my yard in one go. I can do 2/3 with one battery. Then I need to take a +2hr break to recharge the battery before I can do the rest. I will never buy a Gardenline product again and I will never buy an unknown brand at Aldi again because of their lack of spare parts and service.

    • We once had a difficult experience with an Aldi vendor and we ended up contacting Aldi directly after the vendor was unresponsive. ( We found them helpful in getting the situation resolved.

  12. Last year I bought all three of Aldi’s Gardenline cordless yard tools: The edger/trimmer, the hedge trimmer and the blower. I wanted to wait to review them until I had a chance to use them for all of last year. I am happy to report that I am very satisfied with all three.

    These are light duty items, so as long as you keep that in mind and your needs are not severe, they are an excellent value. I think for most average sized suburban yards, they would be plenty adequate.

    As the review above noted, each item comes with one battery. This is cheap, but the battery life is actually good. I can do all the bushes in my yard (a lot, 30+) with the hedge trimmer on one battery. I can do the sidewalks and driveway with the edger on one battery as well. The blower uses batteries the fastest and sometimes requires two batteries if I am blowing a lot. By buying all three products, I have three batteries which eliminates any potential battery anxiety. On the rare cases when I would use all three products on the same day, it would be a long enough project that I could plug depleted batteries in as I use them and they charge pretty quickly. I like the charge indicator on the batteries, too.

    The edger does use very thin trim line, with only one line sticking out rather than two like heavier duty edgers have. This worried me initially, but it works well enough for my needs. I live in Houston, where we have thick St. Augustine grass and it will cut through it fine. Maybe not instant vaporization like you would get with a powerful gas unit, but good enough. I replaced the .055 line with .065 which is easier to find. It doesn’t advance quite as easily, but it fits and has the advantage of being a bit tougher to break. I like the rotating handle and adjustable head. I can use it vertically like an edger for sidewalks, then switch it to horizontal for other trimming. The small wheel is a nice feature for edging.

    The hedge trimmer works great. It is a bit smaller than some I’ve seen but I have no complaints at all about its function. As I mentioned above, you’d have to do an awful lot of trimming to run through a whole battery charge.

    The blower is the most conspicuously light duty of the three. Don’t expect a wind storm to come out of it like you would get with a larger plug in or gas unit. For my purposes, though, it is fine for collecting grass clippings on the driveway or patio. I kept my plug in blower for collecting leaves in the fall. The Aldi one is too small for that. The switch might be a weak point with these. My switch failed pretty soon. Fortunately, the stores still had them in stock and I was able to exchange it for a new one no problem. It went the rest of the season without any issues.

    • Hi Jonathan, where did you get your three batteries for your products?ca i use Black and Decker 20v Lithium-Ion 2000mAh battery for the 20v trimmer. I had purchased just two months back but the battery is not recharging not sure what is the issue.

  13. Hi,
    Wanted to let everyone know that I was able to find supplies for the Gardenline trimmer at
    This company, Force Tools USA only ships orders to the 48 Contiguous United States and Canada. We were able to buy they replacement line, 0.055″ and also an extra battery for our trimmer.

    • “WORX WA0010 5 pack Replacement Spool Line” on eBay less than $10.00 it fits perfectly for my Gardenline trimmer model # 52646.

      • The Gardenline string trimmer changes from year to year, but the model number doesn’t. The string for the trimmer I bought this year doesn’t work with the trimmer I bought this year, nor were the batteries inter-changeable either.

        What year did you buy your trimmer?

  14. Harry E McCarty

    First, while my grass trimmer has the same number-52626, it looks different . My handle is black and was purchased in 2019. I cannot move the head angle on mine or do not know how this is done.

    • Interesting, the trimmer I purchased this year has the same number #52646 as the trimmer I purchased last year, but the string (spool head is smaller) is different and the batteries were not inter-changeable.

  15. I bought the Gardenline cordless string trimmer along with the blower and hedge trimmer. Since the batteries are interchangeable I rotate keeping one or 2 charging while I am using one. They are light weight and easy for ne to use. I am unable to pick up much weight due to spinal surgery. My batteries lasted 2 years before needing replacement. They work better than my husbands high dollar gas powered weed eater and blower. My son uses them when he does the neighbors lawns. I would highly recommend these products to anyone. They are a great product and they do a great job.

  16. My line trimmer battery won’t hold a charge now and when I called the company, they stated that they don’t sell replacement batteries, they only replace them within the warranty period. I said “so the whole unit is junk now?” and he said “they were not meant for long term use.” I’ve only had this a couple of years, so I am not impressed! Don’t waste your money!

  17. If you have an ORiley autoparts store near you get them to order the prime Line round cut trimmer line 0.050 diameter. It works in the ALDI Gardenline Cordless Trimmer. Just bought it and used it this morning. I hope this helps.

  18. Gardenline cordless trimmer, piece of junk. Thought was good brother broke cap on line, lost spool. looking 2 years, you go to so called manufacture web site they cant even find. Just Bad company.

  19. rue ann olmstead

    I never even thought about buying replacement line……..
    I just shoved in .080 “weed eater” line, from my 2000 ft. role I had bought years ago. I used it all last year, and the only downside, might be that I only get about as much time out of my battery (compared to this review).
    Works great, and….. I CAN chop down small brush, and big weeds.

  20. My local Ace Hardware was able to order the string for this trimmer. Two pack for 9.99

  21. fyi, I’ve found that if you search by numbers imprinted on the product itself you might find more results than if you search for “Gardenline”. I’m looking for a new battery and when I searched for “ABP118W1” I found a replacement.

  22. Steve Callender

    The gardenline trimmer is a good product, and I’ve been able to find adequate trimmer line.
    The BATTERY, however, only gives about 15 minutes of use.
    Where can I buy a second battery, so I can have a spare if I have more than 15 minutes of trimming to do?

  23. I got a spare battery through this site: They had problems with one of their earlier batches of batteries (casing was opening up because the screws had been tightened too much) but they sent me a replacement which was fine.

  24. The cord will not advance as I use the edger. It has been working fine for a few years. Any advice to get the cord to advance on its own?

  25. I have this trimmer and have been pleased with its performance. The instructions with my trimmer say to use only 0.065″ line.

  26. I bought 2 Gardenline blowers at Aldi for about $15.00 each and was pleased, so 2 years later when I saw the Ferrex string trimmer on clearance for $9.50 I bought 2 of those. Not because I needed 2 string trimmers, but because I wanted an extra battery. The batteries from the string trimmers also fit the blowers, which is good, because I now get about 1 minute of run time on the original batteries. While I like them a lot, I can’t recommend them because they seem to be disposable tools. I can’t find replacement batteries anywhere.

  27. Does anyone know if you can use Carbon Steel Wire Wheel on this weed whacker and if it is a 6 inch or 8 inch. I’m trying to do without the string trimmer.

  28. The cordless trimmer/edger is back at Aldi the week of April 10th, 2024.

  29. I just bought a brand new one and I can’t tell if it doesn’t have a thread or if it’s broken

  30. How can I purchase the replacement spoons for the trimmer?
