Greenworks 80V 18" Brushless Cordless Chainsaw (Great For Tree Felling, Limbing, Pruning, and Firewood) / 75+ Compatible Tools), 2.0Ah Battery and Rapid Charger Included

I bought this because we have 50 acres with a bunch of medium to large trees that are always having limbs break that need to be cut up. I own a small 20 V electric chainsaw, and I have absolutely loved using that but cannot handle anything bigger than 8 inches wide. I have owned gas chainsaws in the past, and I have absolutely hated them. They leak oil, they smell like crap, they are way too loud and they in general extremely unreliable. I bought this chainsaw because I had such good luck with my little Electric one I figured why not get a nice big electric chainsaw, and since I already own Greenworks products, reliable and well-made. I figured when I first got the saw OK it’ll be quieter but it’ll probably be slower and heat through batteries pretty quickly which I was already prepared for because I have a bunch of 80 V batteries but after using this thing the first day, oh my God! I fell in love! This chainsaw is so easy to use and the battery life is excellent even with the 2Ah battery. I typically run out of energy before the chainsaw does. This chainsaw runs a little bit slower than a gas chainsaw but anytime you might spend cutting a little bit longer is easily made up in the fact that you don’t have to mix gas and oil fiddle around with a carburetor or a pole start being said this chainsaw goes through stuff pretty quick, and I have yet to have it stall on me and I have cut a pretty large tree with it as seen in the photos. This chainsaw with the battery equipped is slightly heavier than a gas equivalent, but it’s barely noticeable to me, and this thing won’t vibrate your hands to kingdom. Come like a guess one. I’ve heard people complain about the fact. This thing leaks oil, but that has not been the case with me apart from the residual oil that is on the bar when you’re done using it and honestly you won’t find a chainsaw that doesn’t leak from time to time. I’ve also heard some people show dislike for the auto off feature, which in my opinion is nice to have because you don’t want the chainsaw on for very long unattended and turning it back on is literally as easy as just clicking a little button right next to the trigger so that is not a problem at all for me. The only thing I might say I’m not too much of a fan of is the fact that the bar is so skinny , but that comes with positives and negatives. The posit is that it has a bit of flex and when you’re cutting so if you get hung up, it’s a bit easier to free it and so far only negative with it is that it might make it a little bit easier to derail the chain , but considering the chain never gets hot like a chainsaw you can take the little tool out of the back of the chainsaw and take the cover off realign the chain and put it back on within a minute. Don’t hesitate to get this because it really is a night and day difference from using a gas chainsaw. You can use this anytime of the day and not piss off your neighbors and it’s in general a lot more fun to use because you’re not worrying about dealing with all the hassle of a gas chainsaw so you can just pick it up put a battery in it and go to work. I would definitely buy this again!

I can't say enough about this. It's an amazing saw. I'd give it 6 stars if I could. I've had Husqvarna, Craftsman and several other gas saws. This is soooooo much better. I never have to deal with stalls, gas/oil mixtures, it shuts off between cuts, it's quieter. I absolutely love it. I bought extra batteries for longer run times. They charge in about 20 minutes so I can swap around easily if there's power nearby. I've downed and cut up 16" diameter trees, cuts through limbs like butter. Most of the time I run a 14" bar and chain. That's long enough for most of what I do, lighter and easier to wield. I don't know if I'd want to deal with recharging if I was an arborist for a living, away from a power source, but for general home use, this thing is nothing short of life-changing. I used to dread having to get my saw out, wrestle with starting, fueling, maintaining and stabilizing the right mix, etc. I leave this on the back porch and grab it whenever I go out for firewood. Because I don't have to use gas/oil, I can throw it in the cab of the truck any time and not worry about fumes or spillage. Starts and runs every time. It's taken chain saw use from frustrating to fun. My one hesitation is that I haven't used it in the summer yet. I have a little 20v Black and Decker that heats ups and shuts down quickly in anything but the coldest weather. This 80V Greenworks has never shut down on me and I've seen reviews that says it doesn't have overheating issues but I'll test that for myself over the hot southern NC summer. I also bought the Leaf Blower (https://www.amazon.com/gp/product/B0CLSDL517) so now I have two chargers. The leaf blower is also great. I'm recommending both to family and friends.

I've been using chainsaws on a regular basis since 1979, but I was a little reluctant to purchase a new battery-powered saw. The Greenworks 80 volt saw cuts very well, with the battery lasting about 45 minutes during actual use. I cut up a 16" diameter sugar maple with as much ease as my Stihl 251 which I've been using for the past eleven years. Purchased at the sale price of $209, this Greenworks model is a terrific bargain. Highly recommended.

The manufacturer claims this chainsaw equals a "45cc gas engine equivalent" and I agree, now having owned it for a month. The power seems about equal to a 45cc conventional chainsaw. The battery life is good, lasting about as long as 1.5 tankfuls of gasoline. The weight, 14.8 pounds, is heavier than most 45cc conventional chainsaws. It starts effortlessly with a button-press at a variety of altitudes, far more convenient than conventional chainsaws. It is quiet while cutting and silent between cuts -- no earmuffs needed -- what a treat! I keep a chainsaw on the tractor to trim errant brush I might encounter while out doing tractor-chores. It turns out this Greenworks chainsaw is TOO BULKY and TOO HEAVY to assume that role. This saw is even a bit too large for comfortable limbing. Minus one star. It excels at felling and bucking, however; exactly the roles you would expect for a 45cc equivalent. I'll be keeping this saw and parting-out the Stihl saw I bucked with last season (47cc). Another day I might try the Greenworks 40-volt chainsaw and see if that's suitable for tractor duty. Do yourself a favor -- if you choose to buy this saw, buy all the proper accessories up front. I highly recommend a chisel chain from Oregon OREGON 91VXL062G 62 Drive Link Long Top Plate 3/8-Inch Low Profile Chain , which performs far better than the stock "low kickback" chain designed for children. An Orgeon chain works nicely with an Oregon bar: Oregon 180SDEA041 .050" Gauge 3/8" Low Pro Pitch 18" Double Guard Bar . Replace the two bar nuts with a standard size that's easy to adjust: these Bar Nuts Replaces Stihl 6 Pack fit perfectly onto the M8-sized studs. Greenworks forgot to include a scrench in the box, so buy your own: Oregon 512959 13mm by 19mm Chain Saw Scrench . Unless you're accustomed to taking breaks every 1.5 tankfuls of gasoline with a conventional chainsaw, you'll want a second battery: GreenWorks GBA80200 80V 2.0AH Lithium Ion Battery . And lastly don't forget to stock up on bar oil: Oregon 54-026 Chain Saw Bar And Chain Oil - Quart . A tankful of bar oil seems to last 3 or 4 battery-charges. In summary, this Greenworks saw turned out to be too bulky and too heavy for the role I envisioned. On the other hand, I've had fun felling and bucking about 2 cords of woods in the mountains of West Virginia with it so far. It really has replaced a 45cc conventional chainsaw for me; it's a nice complement to the 34cc and 57cc saws I operate also. 4 stars. UPDATE SUMMER 2017: After two years of ownership now, my 4-star rating stands. I no longer own a 45cc conventional chainsaw, nor do I need one. I rely on this Greenworks 80v saw for all of my bucking and for most felling, 4 to 5 cords yearly. This saw is a bit bulkier and heavier than a 45cc conventional chainsaw, yes, but I choose it nonetheless. I tolerate the excess bulk and weight because I enjoy the always-starts performance and relative quiet. My biggest gripe is premature battery failure: of the four 80-volt/2-amp-hour batteries I purchased, none lasted longer than a year. This corresponded to 100 or 200 charge/discharge cycles each. Contributing factors may be exposure to cold winters (-40F) and wetness - as my firewood tools sit outdoors year-round. On the plus side, Greenworks covers these battery packs with a 2-year warranty. They replaced each of my four batteries upon request, cheerfully, at no charge. I'll give credit to Greenworks for good warranty service and so will not dock them another star. A correction to my review above: Greenworks *does* include a scrench (screwdriver+wrench tool) in the package. You need not purchase the scrench and bar nuts I linked above. My mistake. Greenworks conceals its scrench inside the saw handle, at the bottom corner, next to the site for the little finger of the right hand. Took me longer than a year to discover that gizmo. For tractor duties and for limbing, these days I am happy using the Greenworks 40-volt chainsaw, GreenWorks 20312 G-MAX 40V 16-Inch Cordless Chainsaw, 4AH Battery and a Charger Included , as hinted in my review previously.

This thing is pretty amazing. Slices through huge trunks like butter. A bit scary, has lots of safety features and I can see why, but if you want to seriously cut some wood, this will do it. Battery charges quick too.

If I could give this review zero stars, I would give zero stars; but apparently that is not an option. I own many Green Works products. I started in 2015 with a push mower I still use today with its original battery. I purchased a 2nd Green Works lawn mower with self propel to help me mow our hill in the backyard. I own, a snow blower which is nice when you live in Green Bay, Wisconsin! I have two weed trimmers, a pole saw, and an edger. All of these products work great! I even owned a Green Works chain saw and used it so much I worn it out and could not get replacement parts to fix the cracked oil chamber. So I decided to replace my old Green Works saw with this saw in July 2025; BIG MISTAKE! The saw worked fine the few times I used it in the first 45 days, then it would stop cutting sometimes a few seconds into a cut, sometimes a few minutes after I started cutting. New chain, good bar, lots of oil, charged battery, just stopped working. Here is were Amazon earned an F. When I called Green Works for support they wanted the model number off the saw and serial number. I gave them everything including information off the original box and my Amazon receipt showing the purchase dated July 2025. The saw Amazon sold me was manufactured on 4/17/18. The batteries in the box were manufactured in 2025. This became a huge problem with Green Works. They would not replace the saw and continued to give me the run around. Record videos of the problem, take pictures of the saw. Green Works even sent me a new chain, which I knew would make no difference since I had already installed three new chains on the saw and it solved nothing; the saw still stops working. I brought up my problem with Green Works with Amazon customer service in chat and explained the date on the saw does not match the date on the box, charger or battery. The representative from Amazon said they would help me and refund my money. A week went by, no refund and when I contacted customer service again, they said no refund can be issued even though I was promised one by the first customer service representative I chatted with. Amazon said that representative made a mistake and no refund would be issued. In the end Amazon did nothing to resolve the problem but direct me back to Green Works, which is not willing to honor their warranty on the product. My advice to anyone buying Green Works tools from Amazon, be sure the item is the current year model and not some other product they dumped in a box, because that is EXACTLY what happened to me. I did not see the manufacture date on the saw or I would have returned my Amazon purchase IMMEDIATELY thinking there was someone wrong with this order. So now I have a saw that does not work. Amazon customer service will not help me and Green Works keeps giving me the run around. It is not like I am new to Green Works products. I have been a loyal customer for over 10 years using lots of their tools. I am also a very experienced chain saw user. I have been cutting wood since I was a kid with lots of experiences, breaking down gas powered chain saws, cleaning and sharpening chains and dealing with chain saw related issues. I do not recommend this saw and I would watch your manufacture dates on any products you get and question all items you purchase as being new and the original product placed in that box by the manufacturer. I do not expect to get any kind of positive resolution to this matter, but I am documenting this poor review for all other customers thinking of buying any Green Works product from Amazon. Watch your dates; they are playing games with the products they sell and will not back you up after the sale; specially if the 30 days have passed. After that time, you are DONE; zero support from Amazon!!

I ordered this battery-driven 18" Greenworks chainsaw through Amazon some weeks ago. This is an amazing chainsaw -- the best I have ever owned. For most homeowners with light-to-modest chainsaw needs, it beats both hard-to-start and testy-to-maintain gas models, as well as corded electric models. I have several large-diameter oak and pine trees on my property that were felled during a tornado. This saw makes light work of them, with these sole qualifications. First, though portable like a gas saw, this Greenworks model is hefty once the weighty lithium ion battery is fitted. Second, it is necessary not to overwork that battery. The problem is not with its life -- it will continue to provide power for loads of cuts, fully re-charging in just 30 minutes -- but its overuse. When overworked and therefore overheated, the battery sends out a warning beep to give it a rest for awhile. I recommend giving the saw a five-minute wait between two large-diameter hardwood cuts with a sharp chain, for example. Third, like any chainsaw, the chain needs sharpening after virtually any heavy use. Sharpening is an art, but one that can be mastered through trial and error. I recommend purchasing the German Pferd CS-X Chainsharp sharpening tool, which files down both the teeth and rakers simultaneously to the correct tolerances. Just be sure to order the 5/32" / 4.-mm model, available online for about $35, including spare rat files, through Centerline at www.centerlinedistribution.com. It's also smart to have at least two sharpened chains available for any project. This 18" Greenworks chainsaw uses the 62-link Oregon 3/8" low-profile chain, 050"/1.3 mm gauge, AdvanceCut model 91PX062G, about $16 each plus shipping online. I ordered three chains online to pay just one $8 shipping charge through Chain Saws Direct. Took just five days to fill the order.

I bought the Greenworks Pro 80V 18-Inch Cordless Chainsaw in late November 2020 to augment a 10 year old 20" Husqvarna Rancher 455 that was getting a bit finicky to start (I ordered a new carburetor for the Rancher but that's a story for another review). I have two properties that are fairly well wooded; so it seems I'm pulling the chain saw out about a half-dozen times per year for trimming or dealing with large fallen branches or whole trees. Typically a big job for me would be 6 to 8 hours to cut up a fallen tree. If you use your chain saw much more than me, then the Greenworks (or any electric or battery model) is probably not for you. But if you need a chain saw for small to medium jobs from time to time, then I encourage you to try the Greenworks saw. The saw arrived quickly from Amazon and was packed reasonably well. The battery was wrapped but was bouncing around a bit in Greenworks box. Setup is a snap, just charge the battery, put chain oil in the saw, pop-in in the battery, press a button and pull the trigger. Again, this will not replace the power and heft of mid-to-large gas powered chain saw, but the Greenworks certainly held its own. Out of the box, with the factory chain it cut through 6 -10" red oak and silver maple logs pretty quickly. Its obviously significantly lighter overall than the Rancher and I noticed a bit of "chatter" when starting a cut. But with a bit more pressure it cut really well. The first day I did at least 75 cuts and the battery still had more power, but probably not a whole lot more. After working, the battery charged in less than 30 minutes. The saw is very easy to handle, balanced well, and I do feel safer using the Greenworks. It stops very quickly when the trigger is released or the hand brake is engaged. I had absolutely no chain issues, though I will say it came from the factory adjusted pretty tightly (which I left as is). Mine has not leaked any oil after sitting around for a couple of weeks. I like the see-through chain-oil reservoir as I can see the level slowly going down while cutting. The stock chain wasn't bad, but obviously I don't know how long it will last until it needs a sharpening. I will likely buy a slightly more aggressive chain, Oregon has three models that should fit. Note that some of the chain companies indicate a 63 link chain is needed, BUT IT USES A 62 LINK CHAIN. I didn't have any battery heating or cutoff issues, as I typically do 4 or 5 cuts, then stack, and then reposition the main log. I did buy a second battery, but I'm not sure I'll need it, as the recharge time is pretty quick. I did find that the two nuts holding the chain bar were loose after using the saw for the first day, so be sure to regularly check and tighten them as needed (with the wrench tucked away in the handle). SO... bottom line, I really like the saw. There's nothing like not worrying about starting or keeping the saw running. I'll post an update if any issues arise.

The Greenworks 80V 18-inch chainsaw (model GCS80421) is a cordless tool for casual users needing a low-maintenance option for small yard or outdoor jobs. It’s powerful for an electric saw but doesn’t match gas saws for heavy-duty work, but it will do the job. Performance: With a chain speed of ~65.6 ft/s (20 m/s), it’s close to entry-level gas saws (60–80 ft/s) but cuts slower due to lower torque—same chain, less grunt. It handles branches up to 10 inches but if you lean into the cut it will stall. Stalling triggers a beep, a stop, and a short wait, which breaks your rhythm. The Greenworks 80V chainsaw uses the chain model 29152, which is an 18-inch replacement chainsaw chain with a pitch of 0.05 inches and a 3/8-inch gauge. This 18 inch chain is the narrower gauge normal for the smaller saws (16 inch and less) allows faster/easier cutting. I have had to adjust the chain often as it appears to stretch. the file is 5/32. Battery Life: The 2Ah battery lasts 5–10 minutes of continuous cutting (e.g., small logs or firewood). Lighter tasks like pruning might stretch it, but heavy cuts drain it fast. The saw goes through chain oil at a rate of one fill per battery charge, so remember to bring some along with you. Larger 4Ah or 5Ah batteries are available, (costly) but I haven’t tested their runtime or power. Usability: At 15 lbs with the 2Ah battery, it’s heavier than compact gas saws (9–10 lbs). Starting is a breeze—just insert the battery and go. No gas mixing or carburetor hassles. Applications: Ideal for small jobs like yard cleanup, clearing hunting trails, or cutting campfire wood (<8-inch logs). It’s not a pro-grade saw for big tasks. Pros: No gas, minimal maintenance Portable for light outdoor use Quiet and easy to start no gas smell can sit or months without problems Cons: No gas but you still need chain oil spare/replacement battery costs almost as much as saw. Slower cuts, power drops with battery charge level, where a gas saw (10,000rpm) vibrates this electric is more of a rattle as you feel the chain teeth as rpm is lower 2Ah battery lasts 5–10 min cutting Heavy (~15 lbs) vs. gas saws Verdict: The Greenworks 80V 18-inch chainsaw (GCS80421) is solid for homeowners or hunters tackling occasional small jobs. If you’re used to gas saws, its short battery life might disappoint—consider a larger battery for longer cuts.

Came quickly. Works great. Quiet and no gas or fumes to deal with. Bough5 a couple extra chain.s. Battery lasts quite a well too

Va super bien vraiment content de mon achat

Background -- I live on a 6.5 acre hobby farm and own two Echo chainsaws (18" and 20") to compare to. They, and all the other two stroke engines I have around here are a constant headache. I also own a diesel tractor, a zero turn, and in the past had walk-behind tractors, rototillers, gas pressure washer, etc. Lots of small engines, so much so that after a couple years of living here I went out and took a small engine repair course because dealing with this stuff became expensive and a hassle. I basically have come to hate the smell, the noise, and the hassle of two-stroke engines. Won't start half the time, carburetor clogging up, yanking a stupid start chain over and over again, refilling with fuel, polluting like crazy, etc. etc. I am also an owner of an electric car and a plugin-hybrid, and I own a few other things in the Greenworks 80V Pro collection (lawnmower, string trimmer, and hedge trimmer), so I already had two battery packs and a charger. I was unable to find the 18" version of this chainsaw without the battery and charger, so I have now have 3 packs and two chargers. Which is not necessarily a bad thing as I'll explain below. Most other machines that operate on wood are electric (saws, planers, drills, etc.) so why not a chainsaw? I was very excited to get my hands on this. Now to the review. It's fine, actually excellent, for power. If you keep the teeth sharp you will have no problems. I got it today and took it out straight away to cut up a couple spruces tree I had felled earlier this spring. Softwood, yes, but thick diameter (up to 24" or so) and had no problems. I then cut the stumps down as low to the ground as I could, and that worked well, but drained the battery more quickly. I did a few more cuts, and did some lengthwise cuts on some longer pieces to see how it would do. Overall, power was good. Cuts were clean and pretty fast, and I only stalled out once when I got in an awkward angle. I did have to swap the battery pack twice, but by the time I came back to the charger for the second swap, the first was already finished. With the two chargers and three packs that I have, I could probably go continuously. I was very happy to not have the smell, the noise, and the hassle of starting/stopping like with my gas saw. In terms of the actual build of the saw, I'd say this is the weaker side of the product. The bar is flimsier than my Echo saws, and the plastic housing not as strong or nicely put together. The handle is not as comfortable, the plastic thinner, etc. The tightening system is very similar, but not as robust. The chain did come off at one point, as others have complained about -- likely because it needed some tightening -- but the saw stopped immediately so it wasn't a safety concern. I haven't had problems with the bar oil tank like someone else was complaining about. So I feel like this product is 85-90% there. I far prefer using it (vs my gas saws) so .... given that there's always something to cut around the farm, I will probably end up breaking it over time by taking on too big of tasks with it... But it seems to me like most of the parts in here are fairly replaceable, as long as Greenworks is committed to this line and battery pack over time. But I do hope they come out with something that is just a bit beefier, maybe even something that takes their larger battery pack and has a 20" or bigger bar? That would be awesome.

Good for limited use. If you need extended run time definitely get a 2nd battery.
