This is an older model. The newer model is sold by Costco (and GW online). I've owned both, and both work well. The newer model has a "turbo" switch on the controls, allowing you to set the higher speed without relying on the auto sensing feature. The new model also has a slightly different handle that folds more easily, and also has two battery ports that switch from the depleted battery to the fresh one automatically.

I bought the newer model from Costco about a year ago for $499 with two 4Ah batteries. The GW tools and batteries sold by Costco come with an 8 year warranty...4 from GW and additional 4 from Costco. If you see the new model from Costco on sale again (Reg $649) for $499, it's a better deal....2ea 4Ah batteries, plus the 8 year warranty on both the tool and batteries.
One more thing. It ships in mulch mode and that's the way I left it so no emptying the bag over and over. Don't even have to attach the grass catcher. I raised the cutting height from 1 to 3 (out of 7 positions). It also has an auto-sensing technology that speeds up the blade when needed (thick, tall, wet grass), then slows it back down.

I swear I don't work for Greenworks. Just more than impressed with what they've done here. You can see the before and after of what I found when I got here and what it looks like now.

I wonder why they are getting returned.
I noticed that too. I'm wondering how they get so many of these returned when they have so many shipping restrictions that they seem to have trouble just shipping any of them anywhere in the first place. Confused

That's a great deal! The second battery is what I really wish I had. But I needed this ASAP and couldn't really wait for a better deal than Walmart shipping this one to us in 2 days for free. (Unknown Bonus was a cashback site with an R was running some kind of deal where I got 7% cash back on the $434 the day I ordered.) With the 5Ah, I was able to cut the side (between the next house over) and 90-95% of his front yard you see in the photo. I was trying to cut it before dark, so I didn't use the self-propel the entire time.

Then let the battery cool down and charged it. The next morning I finished the front and his entire backyard with self propel on and still had 1 of 3 battery lights lit. I've had Black & Decker cordless stuff since they were the awful NiCad, so I always want more batteries. But I can make this work as long as his regular guy comes back (he dropped by yesterday to make sure he still had the job after he saw somebody else cut the grass laugh out loud).

Turbo mode doesn't seem like an improvement to me. Why would I want to manually control something that's been automated? I would rather have it decide when it needs more or less battery instead of me.

And 2 onboard batteries wouldn't sell me either. As soon as the first one depleted, I would stop and remove it and put it in front of a fan to cool so I could start recharging it (although these chargers have a built-in fan to cool the individual cells while charging which is nothing short of brilliant in my book). I would prefer just the 2 4Ah batteries, but not pushing them both around the yard until one dies.

If Costco would've had that deal last week, I would've jumped on it if they could've delivered it quickly. And if the extra 4 years also covers the batteries, then that's like getting new batteries every few years because I seriously doubt these will last anywhere near 8 years, maybe not even 4. But if I can get 4 years of periodically cutting my 94-year-old Dad's lawn when we visit without messing with oil, gas, fumes, etc, with this Walmart version, then I'll be a happy camper.

I'm seriously considering folding it up and taking it home with us because I don't want to come back and find out he's let someone else use it and I'm left with a beat-up mower that no longer holds a charge. Maybe I only need to take the 80V battery? Not many people have those just lying around you know.

So I specifically waited to get the version that the other posted listed, but I opted to buy the push model (not self-propelled) to save some money and because I count mowing the lawn as a physical fitness activity (lol). Well, that and because I also need to navigate around a bunch of objects and such so I didn't want to fiddle with the self-propelled controls. Anyway...

I wanted that version because I really wanted the updated folding mechanism. It's so much easier to pull the mechanism and fold the entire thing over rather than having to fiddle with the knobs. The manual turbo was also a key feature for me because I ALWAYS leave it on due to the fact that I don't bag the clippings - no matter what the length of the grass I want the mower to chop it up as fine as possible so that it can break down more easily to feed back into the ground for the turf. Due to the fact that I always leave it on Turbo mode the extra battery bay is nice because I don't have to go all the way back to the garage to grab the second battery.

It's quieter than a gas mower for sure, but I imagine that it's a bit louder because it comes with a mulching blade and a vaned plastic piece close to the blade that generates additional turbulence to aide with mulching.

Honestly though either mower is great and does the job. I don't think you need to worry too much about the battery besides keeping it out of any place that gets too hot. The main thing I would do is to keep the underside relatively clean AND make sure that the blade is sharpened. A sharp blade makes a HUGE difference with regards to battery life and health of your turf glass itself. It will make clean cuts on the grass as opposed too ripping and tearing away at it and mulch better while also greatly reducing the amount of resistance for the electric motor. Without how light the mower is (comparatively) and the fact that there are no fluids that can spill anywhere I regularly flip the thing over to check the blade and blow out any grass that's sticking.

All in all I like it a lot more than the old gas mower that my dad had. He still had it, but I ended up getting him a 60V greenworks (his yard is smaller) just so that it's easier for him to take it in and out of the basement when he needs to use it. It's like half the weight of the old gas mower.

"Turbo mode doesn't seem like an improvement to me. Why would I want to manually control something that's been automated? I would rather have it decide when it needs more or less battery instead of me."

I've owned both models, and for my use (always mulching) the turbo mode has much more vacuum/pickup power. The prior model decided when to speed up, often not as often as I wanted it to. It only senses resistance to the blade. I find the dual battery port handy, and since it is self-propelled, the extra weight is not a factor. When one is depleted, it switches to the fresh one automatically. Otherwise, I'd have to stop, remove the battery, walk back to the garage to get the fresh one and go back to the mower and install it before resuming.

Yes, the 8 year warranty covers both the tool and the batteries. If you go to the product page on Costco.com and click "expand" on the description, you can see the details.

It sounds like whatever model each of us has, we're happy with it and that's pretty rare. I was amazed at how much this one mulched with what I was driving it into. Did it leave a few clippings here and there? Yes. But I'm going to cut his yard again in a few days so it should look even better then.

I did see a review on the Greenworkstools website where someone gave these suggestions:


Here is a list of things that may help you
1.) When using self-propelled disengage the last little push forward( a few inches) and the mower will pull back with no wheel lock.
2.) If you use the bag do not let it get to full. It will shorten run time and change the angle of your blade.
3.) Balance sharpen the blade.
4.) Do not store your battery fully charged
5.) Overlap about 10% from your last cut pass or you will get stray blades of grass uncut.


So do you guys balance sharpen your own blades or where do you get it done? I use a Sharpal for the blades on my 19-year-old Robomow RL800. But this blade is huge compared to those and I wouldn't want it off-balance.

I have a cone shaped device that you place the blade on. If it is out of balance it will tip to one side. Grind a bit more off that side for balance. Pretty crude, bu effective, I got it off Amazon years age, you could probably make your own.

I've had the non-self mower 80v and it's awesome. Great cuts, just need to make sure your blade is sharp. Great household tool for the yard. But I think I need the newer 25inch to save me some more time mowing.

I'm in the 40v product line and got the self-propelled lawn mower yesterday. Not too loud (I do not need earplugs), very nice and clean cuts. I'm impressed. Btw, two 40v 4ah full batteries for about 5000sq ft. I don't know if this is good or bad, but if it lasts longer, that would be great. I leave the self-propelled mode on.

Have the two 4ah batteries pack from Costco. I love this mower, also got the weed walker and blower combo (one 2ah battery that's significantly lighter… great for both). Very satisfied, my .3 acre lot only needs a bit more than one 4ah battery, using self propelled and mow about every two weeks when the grass is a bit thicker.

Just need the hedge trimmer and I'd be a very happy boy.

The last time I saw this mower at Costco (in store), it was $599 with one 4Ah and one 2Ah included. They seem to shuffle the package. I hope you find it at the deal I got, with two 4Ah batteries for $499. They usually run lawn tool specials in the fall. Happy hunting!Smilie

I have the latest 80V SP, my GF has the older style 60V SP and I've used it a few times. It is fine for a smaller yard. Also if you are, or intend to buy more tools, it is wise to stick with one battery platform, either 60 or 80 volts. then the tools, batteries, and chargers will be the same. The 80v has a bit more "oomph", but not really noticeable in most situations. It depends on the size of your lawn, the type of grass, and how often you mow.

I think the 60V is fine for most situations. I do like the newer design with the easy folding handle I think I'd go with the 60V from T/S...do you have other 60 or 80V tools? That would be a factor for me.

I have the non-propelled 21" 80V GW Pro, and I bought it in 2017. Love this thing.

I got it on sale with 2 batteries, and having two really makes all the difference. Then I got a third battery with one of the other tools.(I also have the 80V GW Pro weed wacker, blower, and hedge trimmer).

The mower only uses one battery at a time, but having an extra fully charged battery means I never have to wait. It takes me roughly a battery and a half to mow my yard, sometimes if I let it go longer it takes more when the grass is thicker.

I've seen posts about making sure to let the battery cool before charging, and that's probably good advice, but I've never paid any attention. I take the battery out of the mower and slap it right into the charger. I'm wearing gloves so I honestly don't remember every noticing it being hot or anything. Three 2017 batteries and no problems all still kicking.

One thing I do now days is I usually don't run the batteries until they're exhausted. I tend to change batteries as I pass the garage out of convenience instead of waiting until the battery dies. I've come to learn that if I do it differently the battery will almost certainly die when I'm at the furthest point from my house (smile).

Some say that's bad to not run batteries all the way down but again, I've had these since 2017 and no problems so far. Frankly, now coming up on 6 years, I think if all 3 died tomorrow I'd replace them and continue on without a second thought. That said, I hope they don't all die at once (smile).

I like the ecosystem well enough that in 2018 I bought similar setups for my daughter, my sister, and my brother. Of all the purchases, my brother had one battery arrive DOA, so that was a little bit of a pain, but otherwise everyone seems pretty happy with it all. I also got my brother the small 80V GW Pro cordless snow shovel. That was probably the weakest link in the ecosystem, more novelty than for serious use, but his daughter got a kick out of it and good for lighter snows.

My only real criticism for the whole system is that the battery is a little heavy. For the mower that doesn't matter, but for the weed wacker and hedger, it becomes a bit of a workout for me. But I love not having to mess with gasoline for any of this stuff, so it makes it all worth it to me.
