New 40 volt lithium-ion battery self-propelled lawn mower from Greenworks

I just saw an interesting listing on Amazon for a Greenworks 21" self-propelled cordless electric lawn mower, powered by their 40 volt G-MAX lithium-ion batteries. It has two battery ports with auto-switching similar to their Twin-Force model, so it should have at least a one hour run time with two 4Ah batteries. It is similar to their 80 volt self-propelled model with a 3 in 1 steel deck and a brushless motor, seven height adjustments from 1-3/8" to 3-3/4", 8" front wheels and 10" rear wheels, and a 20" long blade. The price shown is $299 without batteries or charger (bare tool), and it is not currently available, but Amazon is accepting orders.

Edit: They've changed the listing status from <Temporarily out of stock> to <Currently unavailable>, so it can no longer be ordered at this time and it may never be available. So at this time the only self-propelled walk behind mowers that use lithium-ion batteries are the 80 volt Greenworks and 56 volt EGO.

Well, it looks like I missed another self-propelled lithium-ion lawn mower. It's the Troy-Bilt TB610 40 volt 21" deck with front wheel drive that is sold through Lowe's for $599. It comes with two 40 volt Core batteries and weighs a hefty 87 pounds.

Thanks for the link to the Greenworks 40 volt self propelled. It is exactly what I have been looking to find. Hoping for availability before next season.

There is also the Ryobi 40 volt self propelled with brushless motor.

It's available again. The model number is MO40L02.

Also, EGO has added a 20" steel deck self-propelled model, but it is very pricy at $749 !

I really like the looks of that one, and I also like the idea of adding more 40v greenworks batteries to my collection. However, I just couldn't resist picking up a self propelled Ego mower for $300 with the quick charger and 7.5 amp hour battery. Compared to my greenworks 25223 19" 40v mower or my Snapper rider, the Ego looked like it gave the lawn a rather rough cut the first time out. I have since purchased a set of replacement blades (one regular and one high lift bagging blade) to replace the blade which looks like the original owner might have tried mowing some rocks with it.
I might have been a bit inefficient using the self propel feature a lot the first time out and the blade might have given the mower more work, but the mower performed well and the battery at least got the front yard cut (a little over 1/4 acre).
I really got it so that this fall I can see first hand how it does at picking up leaves while mowing. I know that my Snapper will not last forever and neither will the shed in which it is stored. I am hoping to find that I can get by with equipment that I can store in my basement and not replace the gas mower or shed, and I really enjoy the quiet mowing with the same batteries from my string trimmer and chainsaw.

Well, it appears that the Greenworks 80 volt self-propelled mower has been discontinued, and has now been reintroduced as a Kobalt model at Lowe’s. It sells for $599 with two 2 Ah batteries, and the model number is KMP 2080A-06.

I was wondering since you guys have some experience using battery powered mowers. When the battery starts running down, does mower start slowing down as the voltage drops? Or does it remain at a constant speed until a certain voltage level is reached and then shuts off? And about how long does it take to recharge the battery? Thanks!!!

unlike some older equipment I own with NiCd batteries, the lithium-based battery stuff I have stops in a second or 2. Not quite like a switch, but very fast.

battery re-charge rates are extremely variable by make/model.

Stop the presses ! So now there’s a self-propelled version of the Greenworks 60 volt lawn mower, that is being sold at Lowe’s for $499 with a 5 Ah battery and charger.

https://www.lowes.com/pd/Greenworks-Pro-GW-60V-21-in-Self-Proplled-Mower-with-5AH-Battery/1000332225

The only complaint I have is that they promise only up to 30 minutes run time per battery charge. I have the push version of this mower, and it can run up to 60 minutes on a 4 Ah battery, so it sounds like the self-propel system uses a lot of power.

Amazon had a few of the 40volt self propelled Greenworks mowers for sale today at $99.99
It must be a last of the line clearance or a pricing error.
I got one on order before it switched back to No Longer Available.
I won't have a review for a few months.

Interesting. I had signed up for an email alert for when this mower became available, and never received one. That price sounds really fishy. Are you sure you were on the real Amazon website ?

I had also signed up for an alert from Amazon and got an e-mail this morning. It would be a little difficult to believe that someone was impersonating Amazon and knew what item I was waiting on an availability alert. I agree though that the price seems incorrect. I just logged in and verified that my account has all of my prior orders and also today's order. I should really know for certain by Friday because I am still feeling a bit skeptical myself.

Strange that you got an email but I did not. I just checked the listing and my alert is still there, but no email in my mailbox. Are you a Prime member ? If so, maybe they give preference to Prime members, or maybe they just send emails out in order of receiving alert requests, or maybe there are two different Amazons in parallel universes. Anyway, I hope you luck out and get the mower at that price.

Go to the listing. If it is out of stock and not currently available, it will show a button for an email alert. If it is out of stock, but orders are being accepted, it will not show an alert button. Which model are you interested in buying, 20” push, 21” push or 21” self-propelled ?

The mower did arrive. Of course at $99.99 it did not include a battery or charger. I only ran it long enough to be sure that it works and it does. The drive mechanism does not seem to fully disengage like the Ego mower, but I will need more time to try that again.
I'm mostly curious to compare how quickly I go through the charge on a (148 actual) 160 watt hour (40volt 4 amp hour) battery using the self propelled function when I know how quickly I go through the 420 watt hour Ego version already. At least there is a storage spot on board for a second battery, but no auto switching.
Real world testing this Spring.

That price is still amazing ! They are currently listing it at $312.02. How difficult is it to remove a 4 Ah battery ?

Yes. Both the 20” and 21” models have ball bearing wheels, 8” in front and 10” in back. I have seen it selling in that price range. Just put it in your cart and then move to “Save for later.” Periodically check your cart to see if the price has changed.

Amazon shows some in their 'warehouse' with notes about cosmetic problems - seem cheap enough at 135....

anyone know just how severe damage is to stuff like that? did they just get scratched-up?


#21

They are used returns. Probably functional, but banged up. I doubt Amazon tests them prior to shipment, and I would not want something that may have been abused by its prior owner.

Also, I have to wonder why Amazon has so many returns, while there are no new ones for sale. There are many complaints of it being extremely difficult to remove the battery, and unlike the Twin Force, it only has one live battery port.

Got my first chance to test out the MO40L02 (Greenworks 40volt self-propelled) and MowerMike was certainly on to something about difficulty in removing the battery. Cannot be wearing gloves and must be rather precise in grabbing the battery at the push tab and the opposing side quite firmly and pulling hard. I tried to grab the battery from the sides and just push the tab with one finger, but there was no room to get a decent grip. Not a deal breaker for me, but it was an unpleasant surprise to find it to be a challenge.
Overall though, with 2 4amp batteries on board (320 watt hour total), I got more run-time than my Ego self-propelled mower (420 watt hour battery) and a better quality of cut. So, I sold the Ego mower to a gentleman with a much smaller lawn and recouped almost the entire cost.
I still cannot believe that the brushless motor is really that much of an improvement in efficiency and really need to wait for the lawn to get growing in order to see if that changes the run-time by a significant amount.

I have just bought the Greenworks 40v one here in the UK with 2 2Ah batteries only has a 41cm. I find is pathetic barely cuts anything, nothing if it damp.Is going to get returned. My dealer is going to bring round a Stihl battery mower for me to try.
If I do not like that it is back to looking for a small petrol one to replace my ageing Honda Izy.

Here are some pics of being unable to grab the battery from its sides. I have to put my thumb on the lower side and use three fingers on the top side (middle one to operate the release tab). It takes quite a grip to lift the battery, or I place a strap around the battery (not blocking the vents) to make for an easy lift. Still losing a few points to the Ego brand in this regard.

I purchased the "tool only" non-SP version of this mower (MO40L01) direct from Greenworks during their 4th of July sale and got it for $199.99 delivered. MSRP is $249.99 so I thought that was a great deal. Already had 2 4Ah batteries and 2 chargers that came with the 16" Chainsaw and 20" Snow Thrower so I figured I was set there. Goal was to spend under $200.00, so I did just that !!

Was looking at the 19 & 20" versions as well on various sites and found a few under $200, but glad I went with the 21" … especially after receiving and seeing that it actually has a 20" wide blade. Seems that all these cordless mowers are this way in that they call out the deck width instead of the cut / blade width.

MSRP of the 19" on GW's site is $279.99 and the 20" is 269.99 … why would you pay more for less cut ??

Anyway, I absolutely love this mower for the very small yard at my wife's office (takes less than 15 minutes) that I purchased it for. Also tested it out at home on our 15,000 square ft. yard that typically takes an hour to cut and I was still impressed that I only went through 1.5 of the 4Ah batteries to cut the whole thing. It gives a nice cut, but I really prefer Self Propelled for this yard, so it will not be replacing either of my S-P Lawn-Boys (10525 & 10323) any time soon.

The 1st time I cut the office lawn, it only used 1 bar of the 4Ah battery. When I cut it the 2nd time I used a 2.5Ah battery and again only used 1 bar. Swapped battery into the 2100202 string trimmer and used another bar (1/2 to 3/4 hr of work total both cutting & trimming).
Then brought battery home with a half a charge left and did a 1/3 to 1/2 my blowing at home with the 24322 blower/vac (15-20 minutes or so on max LOW speed) before it ran out of juice ... not too bad for the "small" battery !! Finished up my blowing with a 4Ah battery, this time on max HIGH speed and had 1/2 of the battery left.

Love these tools so far !!

Now a few questions for you MO40L02 (SELF PROPELLED version) OWNERS out there …

Now that you've had it a while, how do you like it ??

How long does the battery actually last ??

Greenworks does not have the MANUAL available on the web site nor does anyone else so I'm curious as to how FAST the SP speed is … is the speed range stated in the manual like it is for these other GW built versions I could find manuals for ??

0.7-1.2 meters per sec = 1.56 to 2.68 MPH (GW MO80L00 80V 21" Deck)

0.5-1.7 meters per sec = 1.09 to 3.80 MPH (GW MO60L01 60V 21" Deck)

0.5-1.5 meters per sec = 1.09 to 3.34 MPH (Kobalt 40V 20" Deck)

You would think it is a typo with the fastest mower here being the 60V, then the 40V, then the 80V the slowest.

I'd really think you would want to go with 60 or 80V with an SP version, but hey that is why I'm asking.

Me adopting a 2nd battery platform is highly unlikely … 3rd really if you count Ryobi 18V. But if I could be happy with the performance (and speed) of the 40V it would be awfully tempting to pick one of these up to use at home for those times I don't want to smell like two-stroke or just want a nice and quieter walk in the yard.

I did that on their site in the FAQ section for the mower … I'll let you all know what I find out. If I get no response, I'll e-mail them … they were quick to reply (on the 4th of July even) when I contacted them with a problem with the Snowthower that was shipped to me.

Well they answered the question on the site AND sent me a PDF copy of the manual.

Site FAQ Answer:

Self-propelled adjustable speed is a slow walk to a brisk walk. it's approximately 1.5km to 3.0 km; so guessing they meant KPM = 0.93 to 1.86 MPH
This make no sense and is way off of what the other manuals stated that I posted yesterday.

MO40L02 Manual says:

0.5-1.4 meters per sec (1.6-4.6 FPS) = 1.09 to 3.14 MPH

Which fall in line with what other manuals stated; same slow speed as the Kobalt 20" 40V & GW 21" 60V just a tad slower on the top end.

I could probably live with 3.14 MPH

I've been watching the price on this MO40L02 40V Self Propelled mower on Amazon for the past month. It had dipped just below $300 at one point a few weeks ago and I was tempted to order one up. Well since then, it has been over $340 then dipped down to around $310 for a day or two then back up over $340 some time between so I thought … if it goes below $300 again, I should jump on it.

Well, it dropped to $258.37 yesterday so YES at 26% off of the $349 MSRP … I ordered one up. They offered me another $60 off if I applied for an Amazon store card, so I did that too and got it for under $200 before tax ($211.39 with tax).

Price is still at $258.37 today if anyone else wants to jump on this deal !!


Bottom line is I only paid $11.30 more than I paid for the MO40L01 pusher version.

UPS is delivering it tomorrow so I'll use it this weekend and write a review.

Guess if you have a postage stamp lawn, it's all good but if you mow as much as I do (4 acres), only a gas engine wide cut machine will do. Even a 60" deck takes a couple hours.

My yard is about a 1/3 acre and takes me about an hour with my 21" cut / 3.5 MPH Self-Propelled Lawn-Boy.

Don't know anyone who would cut 4 acres with ANY sort of push mower … self propelled or not. Really anything over a 1/2 ACRE most people would have a rider, and many people with smaller yards than mine use a rider.

With the 21" Deck (20" cut) Greenworks non-self propelled version of this mower I was able to cut my whole lawn on 1-1/2 4Ah batteries. I've got (3) 4Ah, (1) 2.5Ah, and (1) 2Ah batteries so I'm pretty sure I have more than enough battery to cut my complete lawn with the Self Propelled version … the self-propel motor would need to use more battery than the blade motor for me to not get the job done and that is highly unlikely.

Grass was not very long or thick when I cut it with the pusher with 1-1/2 batteries, so taller and/or thicker grass will definitely go through batteries faster. Times like that (typically Spring and Early Summer or after heavy rain) would be when I'd just use the Lawn-Boy … times where it is less of a job (typically later in the Summer or when there has not been much rain) would be when the battery powered mower would be ideal for the job.

Like everything else in life, it's all about using the right tool for the job at hand … cordless tools definitely are useful as long as you know their limitations and don't expect them to do jobs that are beyond their capability.

99% of negative reviews are likely people who expected too much out of a product … yes, there is a lot of junk product out there that deserves bad reviews but so far none of the Greenworks 40V G-MAX product line that I've purchased and have been using for the past 3 months falls into that category.

I've been buying Lithium Ion powered tools since 2012 including Ryobi 18V & 4V, Craftsman Nextec 12V, and Menards Masterforce 12V (same mfr. as Nextec) and have had only one battery failure and one tool failure to date. Battery failure was a Ryobi 18V still under warranty and they sent me a new one no charge ... tool failure was a Nextec Drill but it had a ton of use in the 3 years before it died.

Had a lot of 9.6 & 14.4V Makita NI-CD & NI-MH before I jumped to lithium, these were great tools for their time and are still acceptable performers with "good NI-MH" batteries … just got tired of constantly buying new batteries.

Doug - is that non-SP version too heavy to push around? - been kinda thinking about a new mower - the twinforce leaves stragglers and is beginning to show it's age - nicks out of the plastic deck and some odd intermittent delay in starting. I have .39 acres minus the the house and driveway footprint.

It's not bad, actually as easy if not easer to push than the mid 80's Lawn-Boy 21" Aluminum deck mower it replaced.

The GW has sealed ball bearing wheels and only weighs 60.48 lbs. with a 4Ah battery and mulch plug.
The old LB has the bronze bushing mod done to it's wheels so it rolls decent (but not as well as ball bearings) and weighs 58.4 lbs. with a much plate and half tank of gas.

When I bought this house in 1992 at the young age of 29, I used my 1977 Lawn-Boy 7024 21" Aluminum Deck pusher (avatar) until 1999 when I bought the 10323 Self Propelled. I would still switch back-in-forth between my two mowers as the 7024 is just such a joy to use especially now that it has commercial BB wheels on it. Had more yard then too as we had a 20x22 garage and now have a 24x48 garage, wider driveway, and a back patio that displaced quite a bit of lawn.

I do like to push mow my yard every once in a while (got 3 plain push L-B's), but not every week ... more like once or twice a summer. Our lawn is somewhat hilly too, so more reason I prefer self propelled at my age.

You definitely have less grass to cut than me and if it is relatively flat, all the more easier.

I got my pusher direct from GW on a 20% off 4th of July Sale … maybe wait and see if they have a LABOR DAY sale.

REVIEW:

UPS dropped off my MO40L02 around 2:00 and I just got done mowing my complete 15,000 sq-ft. yard with it.

Self Propel Speed on MAX the whole time, grass was long in spots, brown in others so not too much of a load … cutting motor kicked into high speed maybe 6-10 times in the thicker areas but quickly dropped back down to 2800 RPM once I was back into thin. I would say it was very similar mowing to when I used the pusher version.

Took 1 hour 7.5 minutes
First 4Ah battery died at 26:58
Second 4Ah Battery died at 54:41 (close to the same)
Third 4Ah Battery had 2 bars (1/2 a charge) left when done

So since the pusher used 1.5 batteries to do the same work, the Self Propelled drive motor required 1 whole extra battery to get the job done … not bad at all.

Weight comparison with 4Ah battery and mulch plug:
MO40L01 Push … 60.48 lbs.
vs.
MO40L02 S-P …. 64.48 lbs. (only 4 LBS. heavier)

I'm used to Lawn-Boy Duraforce Self Propel (both 1-speed and 3-speed) and the Greenworks lever works similarly (pull bail up to GO / release to STOP), so no big learning curve there. Just like the Lawn-Boys, you need to release the bail before you actually stop the mower to turn as it needs to roll forward a bit to release the drive wheel clutches. Only difference is there is a slight dwell to the propel kicking in on the GW where the LB's belt drive is instant. And since the GW is just an electrical on/off switch, you obviously can't feather the speed with bail movement / pully tension like you can on the LB's belt drive system.

The Greenworks self propel system has minimal drag when not activated too, so it can be pushed almost as easy as the pusher version.

Not quite as fast as the 3-Speed in 3rd Gear as was expected, but not annoyingly slow like a factory stock 10323 1-Speed Duraforce … LB 3rd gear is 3.5 MPH per drive system manual where the GW is supposed to go up to 3.13 MPH per owners manual.

My 10323 has 10550 Gears in it so it is faster than stock, but not quite as fast as the 10525 3-Speed.

I'll have to do some timed tests when I get a chance to see just how fast everything really is in comparison.

Hi everybody, I bought this same mower on sale, but from Amazon Warehouse Deals for a little over $200 with two batteries and all accessories. It looks new, however, I think I know why it was returned. The rear axle is not even, so all 4 wheels do not touch the ground. It's not bent, just looks poorly welded at the factory. Rather than return it, I decided to start the warranty process, however, it will probably take a couple of weeks, since they are out of Canada. Meanwhile, I don't have any welding tools, can I twist the axle somehow, so that both wheel brackets are in the same direction?

If I need to make a new thread, I apologize.

To the previous poster, I don’t think you can fix this problem by twisting the axle. It will remain elastic until it suddenly yields too much or fails. I had a similar problem with an Earthwise lawn mower, and simply used it that way without any real problems. If this really bothers you and still want to keep the mower, you can buy the complete axle assembly from the Greenworks Ordertree website, using the part number shown in the parts list at the back of the manual.

They are sending me the axle, no problems there, it'll just take a while. But this morning I mowed most of my lawn on three wheels and it did a superb job even on tall moist grass, where earthwise mower would clog up every few minutes. Very happy with it.

Right, it was funny finding a qc passed sticker just a few inches above the problem area.

On a separate topic, mine is not a push model, does it make sense to exchange it for a push mower? Price is a little higher, but not sure of the benefit, especially if it eats the battery. My lawn is mostly flat and this mower is much easier to manage than my previous one.

Which Earthwise mower do you own ? Is it one of the heavy 20” SLA battery models that weigh nearly 100 lbs. The Greenworks Li-ion battery models are much lighter, so self-propelled is totally unnecessary on a flat lawn.

160 FOOT Long SPEED TEST in my side yard TEST RESULTS from Saturday:

GW @ MAX SPEED: 160FT in 32-33 Seconds = 3.00-3.09 MPH with fresh fully charged battery
GW @ MAX SPEED: 160FT in 35-36 Seconds = 2.75-2.82 MPH with a 1/2 discharged battery
Mower just seemed a little faster each time I put in a fresh battery on Friday and this comparison proves it was not just my imagination !!
Owners Manual states 4.6 FPS MAX Speed = 3.13 MPH, which is close enough.

10525 in 3rd Gear / 3260 RPM: 160FT in 28-29 Seconds = 3.41-3.53 MPH (s/b 3.8 MPH @ 3000 RPM per drive service manual)

10323 w/ 10550 Gears / 3300 RPM: 160FT in 30-31 Seconds = 3.19-3.30 MPH

These Greenworks mowers with their bigger (10 & 8") ball bearing wheels roll pretty easy and I was curious as to how the rolling resistance compared between the two of them as well as my Lawn-Boys. Had a 28 lb. pocket/fish scale so I hooked this on each mowers handle bar to see how many lbs. of force was required to push (pull) each of them on my level garage floor.

GW Push was maybe a 1/2 lb of pull to move it at a slow walk
GW S-P was 1.5-2.0 lbs of pull
10525 was 0.5-1.0 lbs of pull (ball bearing comm wheels)
10323 was 1.0 lbs of pull (stock plastic wheels)
7270 was 0.5-1.0 lbs of pull (bronze bushed stock plastic wheels)

A real comparison would be on grass but would need to find a relatively flat and smooth spot to do it on and that would be difficult to find in my yard !!

My "Boys" are not getting kicked to the curb any time soon, just love playing with new tech. Tall, thick, or wet grass the Lawn-Boys are more suited for these demanding situations ... heck there are some four cycle mowers have a hard time when the going gets tough.

Dryer lawn, not overgrown and it's hot out ... this is when I'll get out the cordless one.

You will get the replacement part rather quickly. Somehow a 1st GEN (not G-MAX) battery got put in the box with my Snowblower. I sent them an e-mail on the 4th of July expecting a reply the following day. Instead someone from Canada replied almost immediately and got the process of the correct battery going right away. I got the battery sometime Mon-Wed the following week, so it took less than a week to arrive.

Which Earthwise mower do you own ? Is it one of the heavy 20” SLA battery models that weigh nearly 100 lbs. The Greenworks Li-ion battery models are much lighter, so self-propelled is totally unnecessary on a flat lawn.

Yep, that earthwise, full thick steel deck thought. Got to say, it has been pretty reliable. I tend to hit rocks and worried about greenworks plastic bumper.

If it was bent or had a broken wheel, sure. But there is no sign of damage. If I had a blowtorch, I think I could've heated it and twist it back about 10 degrees. But I'll have the part next week they claim, so no biggie.

thanx Doug, yeah, my lawn is flat

ugh - system not quoting - I'm replying to this;


It's not bad, actually as easy if not easer to push than the mid 80's Lawn-Boy 21" Aluminum deck mower it replaced.

The GW has sealed ball bearing wheels and only weighs 60.48 lbs. with a 4Ah battery and mulch plug.
The old LB has the bronze bushing mod done to it's wheels so it rolls decent (but not as well as ball bearings) and weighs 58.4 lbs. with a much plate and half tank of gas.

When I bought this house in 1992 at the young age of 29, I used my 1977 Lawn-Boy 7024 21" Aluminum Deck pusher (avatar) until 1999 when I bought the 10323 Self Propelled. I would still switch back-in-forth between my two mowers as the 7024 is just such a joy to use especially now that it has commercial BB wheels on it. Had more yard then too as we had a 20x22 garage and now have a 24x48 garage, wider driveway, and a back patio that displaced quite a bit of lawn.

I do like to push mow my yard every once in a while (got 3 plain push L-B's), but not every week ... more like once or twice a summer. Our lawn is somewhat hilly too, so more reason I prefer self propelled at my age.

You definitely have less grass to cut than me and if it is relatively flat, all the more easier.

I got my pusher direct from GW on a 20% off 4th of July Sale … maybe wait and see if they have a LABOR DAY sale.

Thought I'd post pics of my 15k sq-ft. lawn so you can see exactly what I mowed last Friday with the Self Propelled MO40L02 with only 2-1/2 4Ah batteries … I think it is pretty impressive !!

Got my axle put in and mowed the lawn properly for the first time. What a difference! The only problem is that I had about 10 sq feet remaning and the batteries wouldn't charge due to being "too hot". Perhaps I shouldn't be mowing in 90 plus temperature anyway. Between this mower and selling the old Earthwise, I'm down less than $50.

Interesting that your batteries were too hot to charge … when I cut my yard with the Self-Propelled model this week and 2 weeks ago, the batteries were NOT too warm after 25-30 minutes of continuous mowing either time for the charger to start charging right away. I was surprised actually since they are usually too warm when I use them especially with the blower. Temps were in the high 70's maybe low 80's so maybe this helped and I was using 4AH batteries. Don't remember if I was able to immediately charge the same 4Ah battery after 40 minutes with the pusher version when I cut my whole lawn with it the one time 2 months ago.

I'm guessing you have the 2.5Ah ones which would normally come with the MO40L2512 pusher (assuming this is what you've got) and maybe since they discharge faster, they can get too warm especially if it is hot outside.

I've got a 2.5Ah battery so I'll start with this when I cut next to see if it gets too warm in the SP version.

Click to expand...

The 10525 speed was too far off of spec in this 1st test (s/b around 4 MPH @ 3200 RPM) and the Greenworks was a bit slow too (s/b 4.6 fps or 3.13 MPH) so I decided to lengthen my test by another 40 FT to 200 FT thinking I would get more accurate times with the longer test:

10525 in 3rd Gear: 200FT in 35-36 Seconds = 5.56-5.71 fps = 3.79 to 3.89 MPH

GW @ MAX SPEED: 200FT in 40-41 Seconds = 4.80-5.00 fps = 3.33 to 3.41 MPH (fully charged 4Ah battery; did not have a less than full battery to re-test)

Definitely feel these results are more accurate.

Cut my yard again with the SP-GW again this week … grass was a little longer and thicker than 2 weeks ago thanks to all the recent rain we got and 1st battery did not last quite as long as the last time (did not time it though) as would be expected if it was working harder. Also my wife was cutting with me, so I only cut about half the yard this time so battery usage for whole yard could not be compared.

Ran the MO40L02 Self-Propelled again yesterday.

Had been cutting at setting "4" (2-5/8" cut height) for the past couple months because it has been so dry but dropped it down to "3" (2-1/8" cut) this week because it has again gotten greener and thicker.

So this thicker & longer grass was a more real world test for this mower and instead of running at low speed most of the time and jumping up to high in the taller/thick spots, it kicked up to high and stayed there for most of the time … obviously using more battery:
4Ah Battery 1: died at around 19 minutes (vs. 27 with light cutting load)
4Ah Battery 2: died at around 36 minutes (17 min run time)

My wife was helping out again this week so I only cut about half the yard, but I think I had enough batteries left (1 each 4Ah, 2.5Ah, & 2Ah) that I could have got the whole yard done with it.

Mulching like usual and on fastest SP speed and it did a good job … maybe the Lawn-Boy with a sharp Gator/Mulcher would give a slightly better cut when long and thick like this, but can't say for sure.

Could likely have gotten a cleaner/better cut if I had slowed down the SP speed, but I don't care enough to even consider trying going slower … then again, a LB slower than max SP speed would likely give a better cut too !!

Still impressed especially with this being the 40V system and not the 60V or 80V that are more common with the Self Propel feature.

I am noticing when this blade hits something, the damage is much bigger than on my previous mower. I've used two blades in 7 years and they were like new, this is me only mowing twice. I guess I have to get used to this mower settings.

Is there a way to bend these abrasions back or just file them off?

Most lawn mower blades are THICKER than these GW blades … also a typical gas powered engine crank shaft is quite a bit larger in diameter than the shaft on the electric motor used on these cordless mowers.

The cutting edge on these thinner and lighter duty blades is 45Deg, where most mower blades have a 30Deg angle cutting edge … not that this has anything to do with the durability of the GW blades, just thought I'd point it out.

I bent a crankshaft on a Lawn-Boy "F" Series engine by hitting a tree root and this had a 1" crank (IIRC) … did not think I hit it that hard either.

This Greenworks motor has a 17MM (0.668") shaft, so I've been REAL CAREFULL avoiding rocks, curbs, big sticks, etc. when cutting my lawn. If you were to BEND this shaft, I'm guessing you would need to buy a whole new motor from GW, and I'm sure they are not cheap.

All of this may come into play as to why these GW blades seem softer and ding up easier than other lawnmower blades do.

Replacement motors are available from Greenworks, but on the new models you can only buy them as a complete assembly, including the outer housing, battery compartment, electronics etc. I checked the cost to replace the motor assembly on my 60 volt 21” push mower and it is listed as $75 plus shipping. By contrast, the replacement cost for the motor on my 40 volt 19” push mower is only $45, but it consists of the rotor only. Nonetheless, this is still a lot less than the cost of a complete mower tool only.

The motor assembly for 40V MO40L02 (SP) … 311011576 is $180.55 on the GW parts site and is out of stock.
The motor assembly for 40V MO40L01 (Push) 311161571 is not listed.

Only difference between the two is the SP version has a second KO in the shroud base for the SP motor cord and obviously connections & electronics under the shroud for the SP motor. But if I bent a shaft or damaged the blade motor in anyway, I'm thinking the basic motor within the assembly would be the same and likely cheaper to buy the non-SP motor assembly (hopefully similar to the cost of the 60V which sounds reasonable).

Ran the MO40L02 Self-Propelled again today and decided to try it out as a BAGGER at the same "3" / 2-1/8" cutting height as last week.

Got more rain this week so grass was again long and thick like last week plus leaves are starting to fall so I thought instead of mulching I'd see how well it does bagging.

The grass being a similar thickness and length as last week I was surprised that the blade motor mostly stayed on LOW / 2800 RPM speed only kicking up to HI / 3200 RPM in the really thick patches (vs. last week mulching it stayed on HI most of the time). It really does a great job of filling the bag completely too … similar to or possibly more than a 10525 rear bagger can hold.

4Ah Battery #1: died at around 29 minutes (4 bags worth of grass and I left the stop watch go when emptying)
4Ah Battery #2: died at around 54 minutes (mid-way through bag 7)
4Ah battery #3: had 2 bars (1/2 charge) left when done at 1 hour 13 minutes (full bag number 8)

Really thought battery usage would have been similar to mulching since the SP is having to pull the weight of the bagged grass but that was certainly NOT the case. Did a good job sucking up leaves out of the grass too, except in a few spots where they were trampled down … don't think a LB would have sucked them up either.

The cutting quality was very good as a bagger too, also picked up most of the left over clumps from last week mulching where it was really thick.

Did a bagging comparison test this weekend with the 40V 21" Greenworks vs. my 10525 Rear Bagger Lawn-Boy.

Reason I did this quick test was after two weeks of bagging, it seemed that the Greenworks 21" Rear Bagger held more grass than the L-B so with my wife running the GW and I running the L-B I figured the easiest way to compare bag capacities was to dump a couple of each into a Ryobi AC04313 Pop-Up Lawn & Leaf bag and measure the settled depth of grass. The inside diameter of this thing is about 21.5".

10525 with full 100-6362 bag of grass settled in at about 8" of depth at 21.5" dia. ... with simple math this calculates out to:
2639.17 cu-in = 1.53 cu-ft or 1.24 bushels which is less than 1/2 of L-B's published 2.5 bushels.

And YES, I was right the GW bag was 12" of grass depth at 21.5" dia. (50% more) or:
3958.8 cu-in = 2.29 cu-ft or 1.86 bushels.

This was really thick & green grass, so maybe the L-B 2.5 Bushel spec is for really dry grass !!

Don't think I've ever seen a "published capacity" for the Greenworks bag … anyone else know or seen it listed somewhere ??

I've never seen the bag capacity listed for the 21" Greenworks either, however, the 21" 82 volt Snapper bag capacity is listed at 1.6 Bushels. Since the Snapper is just a rebranded Greenworks, I would believe that the bag capacities are about the same. The problem with your test is that the clippings get compressed when you transfer them to the barrel, so the resulting volume will be smaller.

you could cut the bottom off an empty gallon jug, count how many to fill each bag with packing peanuts - compute percent difference?

But, then you've got those dang packing peanuts all over the place!
