The Green Works twin force 40 volts here I bought this back in 2016 April so had it for about two years and at the time I bought this mower because the reviews on this mower were not so good there were a lot of people saying that they were like QC issues and they would die after about a month of use right so I revisited that this year because my Robo-moe failed this is not like a super heavy-duty mower.
I needed you know my robo-moe was mowing most of my yard for me and I would just use this for like trimming up the edges and things like that anyway my Robo mode died finally yet another component on it failed it’s not real great for reliability but anyway so I bought this one I looked at the reviews first and it seemed like people were you know not complaining that it was dying after a month of use anymore so I assumed that they fixed whatever a reliability issue it was that they had so this is the 80 volts 21 inch Green Works pro mower and it has a metal deck which is nice the the 40 volt had a plastic deck and it also has one large blade under the metal deck as opposed to the two blades on the 40 volt and what that means is you get a much better cut it’s it’s just like using a traditional gas lawnmower so anyway I’ve had this mower for I bought it in February late february so I’ve had it for about two months maybe a month and a half something like that I’ve mowed numerous times with it and I like it it doesn’t you know their own they don’t seem to be any problems with it so one thing that I have noticed is like almost immediately this little plastic front cover came loose and I haven’t been able to figure out how to reattach it I assume something broke so that’s kind of chancy but everything else on the mower seems pretty solid I generally with my mowers I run over rocks by accident you know I’ve got kudzu in my backyard so I run over kudzu to kill the roots like you know I abused them i I’m not I’m not easy on my mowers and and this one seems to be holding up just fine in front of me here you you can see a comparison between the batteries I have a whole video by the way the review for this mower I’ve got that linked down below the video in the description if you want to check that out I’m not gonna revisit that too much but I also have a whole review for the the various batteries here that Greenworks offers so these are the 240 volt batteries that go with the twin twin force and these are the 280 volt batteries that go with well these are 280 volt batteries that can be used with this mower this is a 4 amp hour battery and this is a 2 amp hour battery I highly recommend using the 4 amp hour batteries with this mower unless you unless you have a very small yard to mow the 2 amp hour isn’t gonna cut it and I feel like probably the amp draw is high enough that you’re actually heating up the battery too much and it’s reducing you know that the the capacity of the battery as you’re mowing because I feel like these 4 amp hour batteries last way more than twice as long as the 2 amp hour batteries that that you know that’s anecdotal I haven’t done a scientific test or anything but it’s just my my opinion that these 4 amp hour batteries are a much better choice with the with the mower I use the 2 amp hour batteries in my chainsaw so they claim I think that you can mow with an entire battery an entire 4 amp hour battery you can have you know you can buy two of them right so 2 4 amp hour batteries they claim that you can mow with an entire battery be charging the previous battery and and just swap them out and like it’s a direct swap in my experience that hasn’t been the case usually if I have one of these on the charger like I just burned it you know I do mode with it and I start with another one and I mow the entire battery usually the first battery that I’m charging is not done charging yet it’s maybe three quarters of the way charged well one two thirds I guess because the only the only indicator you get are these three LEDs so usually the third LED is still blinking on the charger by the time I’m done having said that two batteries is more than enough for my yards.
I don’t know how much square footage I have but it’s fairly large it feels very uncomfortable to mow with a 21 inch mower just because it takes so long fortunately I have three teenage boys and we usually just swap out and so one of us will do one-third the other do the other third and you know another one will do the the final third and I mean that that makes it pretty manageable and so with all three of us mowing we go through about two batteries to four amp our batteries for this yard so it does work and it works quite well I mean let me get some of this stuff out of the way and I’ll show you some of the features of the mower all right so you know the first thing that most people are probably curious about is how does the battery go and this is one of the four amp hour batteries fully charged and so it just slides into this little slot here and there’s this tab right here at the top for releasing it so you just push it until it clicks and you’re ready to go at that point any time the the battery is in the mower the mower is armed so at that point the way you start it is you just hold down this button and you push the brake it gets louder than that the control board senses the current that the motor is drawing and it will apply more power to the mower or less depending on the load of the work that you’re doing so if you have really tall grass it gets louder and it feeds more current to the motor if you have short grass and it doesn’t have to work as hard than it doesn’t if if you’re mowing you know if you’re just holding the button down over a section of grass that’s already been mowed then it it steps down pretty quickly to its its lowest amp load but it’s an electric mower there’s practically no cost to turning it off convenience wise so when you know when you’re transporting it don’t hold it down like you would with a gas mower just turn it off and then start it back up when you reach the new spot that you want to mow the push-button start is incredibly convenient I like I said usually I have my kids help me mow and they always complain and have trouble with the pull cords every single time I I don’t think they’ve ever gone to mow and they haven’t called me out there to help them start the mower with the push-button start everybody gets it it’s super easy so I highly recommend the push button start it is fantastic if you hate pole cords let’s see removing the battery is just as simple as inserting it all you do is you push down on this tab here that releases it and then you slide it out at this point the mower is disarmed and you can work on it so it has this height adjustment maybe I’m stupid but I always just leave it in the in the number one slot I like to cut my grass fairly low but it has a lot of slots goes all the way up to seven there is a linked cable here or a push rod that raises the front wheels as you know as well as the back wheels at the same time so I don’t know seems like a fairly robust system to me incidentally I have seen I think Green Works licenses the this system to other companies because I’m almost positive that the steal battery powered lithium-ion mower is the exact same model rebranded from Green Works I’ve looked at them in the stores they’re identical they’ve got the same push rod linkages the battery size is the same everything’s the same right it’s just a different color it’s been rebranded also there’s a cobalt mower that I also believe is a rebranded Green Works mower Cobalts like a Lowe’s brand so I don’t know if that’s a an indication that it’s a it’s a good system because other companies are willing to license it or if that’s just an indication that Green Works has a has a good marketing team I don’t know but but there’s that so let’s see the mower itself but let’s flip it over first and then I’ll talk about cost you always want to pull the battery before you if when you do something like this so this is the blade here and as you can see it’s fairly similar to a traditional blade in that it takes one solid bolt to take the blade off however there’s this weird plastic fan thing and I assume that this is to cool the brushless motor I’m not entirely sure I was initially concerned that this plastic fan thing would break when I hit a rock or something but so far it hasn’t broken.
I don’t know what the the durability and longevity of that is but I mean so far after just a month and a half of using it it seems to be a fairly solid system I have mine set up as a mulcher I believe it does come with a bagging option but I always mulch you have to store it inside because it is an electric system and you don’t want to you don’t want to mow in the rain and you don’t want to leave it out in the rain because you’ll probably kill the electronics I don’t think they’re weather sealed so what you’ll find is that if you store it inside and you don’t clean the deck your garage will end up smelling like lawn clippings looks like mine has mold a bit but in practice I I’m fine with that it seems to work just fine I’ve got a fair amount of space where I can store it so it’s good anyway it seems like a fairly robust system I I like it let’s talk cost so again this is 2018 at this time the mower itself each that is not cheap especially when you consider that most people are probably gonna want to buy two of these so total cost of the system it’s expensive but it’s a fairly nice system you know I’m willing to pay it just because I like electric tools I don’t like gasoline-powered tools it’s a little quieter than a gasoline mower so I can listen to books while I’m mowing my kids can start it you know it’s easy to work with I can solar charge the batteries if I want to and I you know it’s better for the environment i I don’t like going to gas stations if I don’t have to I think we need to get rid of ice engines in general so this is a step in that direction I think eventually I’m certain the cost for all of this will come down most I think most of the costs in a system like this is in the battery and also in the controller for the mower or for the for the motor the the electronic speed controllers for these motors are constantly getting smaller and cheaper as time goes by so I I think that that’s going to be a reduced cost issue and also lithium batteries continue to get cheaper as time goes on so I think eventually it’s not unreasonable to assume that you’ll be able to get a mower like this for you know something like that with two two batteries but that’s not today so whether you’re not you want to buy one is kind of a personal choice I like it I’m gonna be keeping mine I’m gonna be selling my twin force so there’s that I don’t feel the need to mow with this on film because it it works just like a regular gas mower I mean it’s great I haven’t noticed any difference between this and my and my couple of you know gas mowers as far as quality goes you know with the twin force it had those two blades and it would sometimes leave a strip down the middle this one doesn’t do that it’s got a single blade it works fine it’s a replacement it’s a gas or replacement it works great so I’m not gonna mow with it on camera but just know that you can pretty much expect it to perform like a like a regular gas mower.
