    The media could not be loaded.

     Winner! I’ll first address things that negative reviews here mention, then give my thoughts on the positives. Before buying, I read some negative reviews about the spool/string. After using the machine a dozen times, here’s the deal.

    First, there are complaints that when you order extra spools, there is an incorrect part number. Okay…..? My advice, just figure out the right part number. What does that have to do with how good the machine is? But here’s the bigger point, if you’re a home owner, you won’t need an extra spool! I have no idea why you’d want one. If you’re a commercial user, okay maybe you want some extra spools to save reload time (I still done see it…takes 3 minutes to reload), but if you’re a commercial user, you REALLY want a battery/gas unit, not a corded (I’ll get into that shortly).

    Second, others complain about the line being too thin. This is untrue. Typically weed eaters with a curve in the frame take the thinner line and those with straight frames take the thicker twine. The thickness depends on how thick the weeds are, but also how powerful the motor on your machine is. I bought the bigger (straight framed machine) and it comes with the line thickness you’d expect (I think it was about .085″). IT’S NOT TOO THIN for heavy home use.

    Third, some complained that the string runs out quickly. This is true. But that’s basically giving the machine a low rating because the company loaded it with half as much string as the “could” have at the factory in order to save money. Annoying? Maybe. But come on, you’re going to have to reload the thing pretty fast anyway. It’s not helpful to buyers looking for a great machine to point them away from this one simply because you wanted and extra 4 feet on string loaded in it from the factory. Imagine giving a great flat screen TV a bad review simply because the remote control batteries it came with were “heavy duty” and not alkaline, so they had to be replaced after only 12 months.

    Forth, some reviews complained that the spool doesn’t hold as much string as I’d wish it would. This is true. And it’s my only real valid complaint. The spool seems small for the size/weight of the unit. This does not compromise the unit. It just means you’re going to have to reload it with string 6 times a year instead of 3 times a year. To me, not a huge deal.

    Now for the good…..

    As a homeowner, I wanted a strong corded weed eater. And this one is THAT. I feel like I’ve owned too many small engine, gas-powered machines that stop working by the third year (weed eaters, ROTO tillers, leaf blowers). Small engine repair is over my head and EXPENSIVE. So I end up throwing the unit away. Electric stuff just works for me as a home owner. What about batter powered units? Battery powered units have gotten better and better. The problem is the life of the battery and its cost to replace. Lithium batteries need to be kept charged up. If you neglect it in the garage (think all winter) the battery will not perform as well, and all too often they die on me by the third year. And the batteries cost so much to replace that I just throw the whole unit away). I want something that won’t end up in the landfill after 3 year. CORDED!! Is it a pain dragging the cord around. Yeah, a bit. But I suspect I’ll have this machine 10 years from now (time will tell). I was surprised at how strong it is, especially for the price.

    If I was a commercial user, I’d go battery powered in a second. They use the units FAR more, so three years on a battery is a good deal for the convenience of cordless maneuverability and travel. But for a home owner, I think it’s not worth it (to me).

    I’m happy with the unit. I’m going to buy a decorative porch box where I can keep a 100 foot extension cord in the front and back and leave them there as “dedicated” weed eater lines. Fast, straightforward, powerful, not batteries to maintain, no fuel fumes….and I’m hoping this guy will still run a decade from now.

    I wanted to allow a couple of complete mowing cycles before giving my feedback on the “Green Work”, And —YES!— I COULDN’T BE HAPPIER WITH IT!

    This machine is extremely powerful, solidly built, and it is aesthetically pleasing too. It can compete in all respects with her much higher-maintenance gasoline ‘colleagues’, and it is much more environmentally friendly. It is also very suitable for a tall person (I am 6’3″).

    THREE RECOMMENDATIONS:

    1. DON’T CUT CORNERS ON THE EXTENSION CORD! Especially if you, as I did, opt for a 100 footer, buy a good 12 GAUGE one (not a 14 gauge, even less so a 16!). As I have said, the “Green Work” ‘s 10 amp. engine is super-powerful, and it would overheat and —ultimately— suffer with a thinner cord. When I called “Green Work” for an advice, they told me that a 10 gauge (the maximum, I believe) would be even better; but, trust me, 12 gauge is perfect. I used my mower in full August Virginia sun, for up to 6 hours in a row, and it never overheated.

    2. USE A VELCRO STRAP INSTEAD. One of the most recurring complaints about the Mod. “21142” is HOW HARD ITS TRIGGER IS. I must admit that, despite being a strong, athletic man, I had to struggle with this issue myself, by resting for a few seconds —every couple of minutes— due to the trigger’s very high tension (unfortunately, by law there can’t be any ‘freeze’ option). Needless to say, this necessity greatly delayed my overall mowing time. But, yesterday, I came up with one of those ‘genius’ ideas that can make you feel very happy, an idea I now want to share with you. With a 9-10″ VELCRO STRAP you can easily block the trigger in the ‘on’ position, you can finally relax your right hand and thus fully enjoy your mowing experience. (As opposed to a regular string or to a rubber band, a velcro strap is very quick to be released and this aspect, of course, is crucial for your safety, here). The Mod. “21142” is a real ‘mule’, and with this new possibility I make it work in continuous mode…What a luxury!

    3. WHEN CHANGING THE LINE FOLLOW THIS VIDEO’S PRECIOUS INSTRUCTIONS! Another problem many customers complain about is the new spool type (black head vs. green head) that Mod. “21142” now assembles. The manual doesn’t make any reference to it, and I know of several customers who literally went crazy trying to figure out how to change the line in this new spool. The following June 2016 video, “Green Works” kindly sent me upon request, is thus A REAL LIFESAVER: […]

    Bravissimo, “Green Work” 21142!

    Huge warning to save others the trouble I’ve been through. Greenworks has changed this trimmer in 2018 and it no longer uses replacement spool 29622. You cannot order a replacement spool on Amazon for this trimmer. I called Greenworks, spent 20 mins on hold to ask them, and they said I could order directly from them. Normally I like to have 2-3 spools and then I used replacement line, which is much less expensive and usually performs better than OEM line.

    The lack of replacement spools (read the reviews for part #29622 if you doubt me) is a big deal to me as I don’t want to have to wait weeks for this to ship from the manufacturer. I want to be able to “buy it now” here on Amazon and have new spools ready to go.

    Sorry, it’s a great trimmer aside from that, and hope they correct this. Easy fix.

    Hope this helps and I’ll update this review if Amazon does indeed begin carrying the spools.
