Upgrade to Greenworks 24V cordless mowing and enjoy eco-friendly power without compromise.
1. Get an additional battery if you have a large yard space to eliminate time waiting on charging.
2. If your grass is tall as mine, remove the mulch bag because it's gonna fill very fast and that's more cutting time to constantly stop and empty.
3. For faster cutting of tall grass remove the mulching gaurd and add a piece of stick to hold the door open. It will mess your clothes but it makes my cutting goes faster (see images attached). It does stop when cutting thicker grass weeds but you just have to start it and pull it back and forth over it and your good.
Overall it's an excellent purchase so far. Let's see how long it will last me.
It cut through my lawn just as well as my old mower did, it got into tight spaces, I could easily pick it up, and the charge lasted through both my back and front yard (and there was a lot of grass!)
It does feel like a toy, so I'm not sure how long it will last (but that's not horrible, considering the price), and the grass catcher is small so you have to empty it more frequently.
It was easy to put together and charge the battery- which is included and can also be used to charge things like phones for some reason.
I'm glad I bought it, it's perfect for my small yards (maybe each are about 50' x 60' in size.)
I'm so happy about it that I had to leave a review! If it breaks, I'll add an update!
(1) I have been using a corded electric mower for about 15 years. I have a very large lawn, both front and back. I’ve made it a point to use a 13-amp mower because it is powerful enough to cut through thick grass and weeds. I prefer electric because there is zero maintenance. I prefer corded because there are no issues with battery charges or battery longevity.
(2) It is imperative that you use a thick gauge power cord to prevent the motor from burning out. The longer the cord, the thicker you need. This is because the electric current diminishes the farther it needs to travel from the outlet to the mower. A thicker gauge will ensure the electricity current’s integrity. I need 125 feet, so I use a 10 gauge (which costs just as much or more than the mower). It can get tricky to become accustomed to using a cord this long, but once I got the hang of it, it was pretty easy. Just be careful… Over the years I’ve mowed through two cords… given their expense, that was very sad indeed. — If you are mowing a smaller area, you probably won’t need to purchases a 10 gauge, but it wouldn’t hurt.
(3) Once an electric mower dies, it’s dead. There is no repairing the motor. I highly recommend buying an extended warranty if you are planning to use the mower often and for large areas.
(4) When mowing tall grass/weeds, do not try to bulldoze through. You could burn out the motor. Tilt the mower up and VERY gradually settle it over the tall grass/weeds. The rotor will do its job without the risk of it getting tangled and overtaxing the motor. Unfortunately, I forgot to do that with my last mower when going over a trouble spot… and I was wearing headphones and I didn’t hear the motor’s distress. I burned out the motor. I had to buy this product to replace it. (You can just imagine how mad I was at myself!)
Properly used, an electric mower will typically give many years of service. My previous two mowers were Kobalt brand. Together, they both lasted over 10 years (with heavy usage). I bought this Greenworks mower because it was convenient to buy from Amazon and the specs are equivalent to a Kobalt. What’s more, it was less expensive. So far, the performance has been excellent. Since I am unfamiliar with this mower’s longevity, I purchased and extended warranty.
Overall, I am very happy with Greenworks. If you keep in mind the foregoing tips, I think you will be happy with it too.
On to the product. First, no assembly required. Remove the cardboard spacers, lift the unit out of the box, decide how you want the discharge to work, everything snaps in or out, set up the handle, pretty intuitive, adjust the cutting height, one lever, plug it in and you're in business.
September 2018: The mower has performed well for three seasons, 2 years on the warrantee. During the last mowing the machine would not restart after a shutdown, reason unknown. Called customer service and they are sending a replacement unit, although that that will take about 3 weeks. I had specifically bought a 100' 12-gauge cord, which I believe is what the manufacturer specified at the time, but am now informed that that is oversize and t should be 14 or 16 gauge. So, wire size is critical.
I ordered the package with the 100' 12/3 cord and the cord reel. The cord seems fine, pliable and easy to handle and lighted at the ends so that you know that you're getting power. The reel was a little disappointing, but at the price it's hard to complain. The main thing is to accept that its purpose is to store the cord, not to help you manage it in use. It barely stores the 100' #12 cord to say nothing of anything more and only if carefully wound. I think that probably the catch that holds the end of the cord to the reel will fail fairly quickly, but hopefully that will not be a major issue. So, you're probably going to strip the cord off the reel and go to work. It is worthwhile to spend a few minutes winding the cord carefully back onto the reel and then be able to carry it easily and store it compactly as opposed to a loosely coiled cord. Given the mower shape and the cord reel I can store both in the space formerly occupied by just by my old electric mower.
I have been familiar with electric lawnmowers since the 1950s; my parents never owned a gas mower. Corded electric mowers are hard to beat for an area that can be reached with a 100' cord from well-spaced outlets. No gas and oil, no exhaust, no tune-ups or mechanical maintenance, less noise, etc. Using this machine today was an interesting experience. My old machine was about 7-8 years old and on its last legs. Clearly not just an electric motor on a platform with a spinning blade as the brand name that it replaces seems to have been, this unit is lighter in weight than my old machine and appears to be engineered to do this specific job. I have a fairly rough semi-natural lot, perhaps semi-neglected would be more accurate. Yard work is the bane of my life; the stuff always grows back. I routinely cut grass, or whatever it may be, that should have been cut weeks ago, do light semi-brush cutting, deep leaf mulching, including those left over from last fall and maybe before, etc., whenever I get to it. I did all of those things today, faster than before with better results, with rpm drops by the motor of seemingly not more than about 10%, and with no feeling that I was abusing the mower.
We'll see how it goes in the longer run. I will change the review and the rating if all does not go as I hope over time.
September 2018: This mower has operated well and as expected for three seasons, 2 warrantee years, with the advantages and some of the noted disadvantages of an electric vs. gas machine. Working yesterday, the machine would not restart after a shutdown. Called customer service and they are shipping a no charge replacement unit, which will arrive in about three weeks. I was instructed to dispose of the the failed unit responsibly, OK. Interestingly, I was informed that the 100' 12-gauge cable, which I believe was their spec of the time, and which I ordered bundled with the mower from AZ is oversized. Don't know enough about electronics to completely understand that, but I'll replace it with 14-16 gauge, which is what they now specify.
Let's get a few things out of the way, these do not impact the product score, as they are common to all products in this category:
1. This is a corded mower. Dealing with the cord is sometimes a pain. If you have a lot of trees or obstacles you may want to consider something else.
2. Maximum power is limited to a 120V outlet and what can safely make it out an extension cord (about 1650W, for reference 1HP is ~745W).
3. With no batteries to wear out or engines to refuel/re oil, this is very cheap to operate. Running this mower at peak output generally costs 8-25c/hour. You also hit an advantage in purchase price as gas or cordless units with the same features generally cost 50-100% more.
4. Short of hitting something, bogging down an electric motor generally allows it to produce more power and speed back up again (unlike a gasoline engine).
So, what's good about this? Well:
1. 21" Steel deck. The actual blade is 19.5" leaving you a little less than an inch on either side of the deck that won't be cut. You can get a much closer cut with this than the B&D plastic models that have a very thick plastic housing. It's also going to survive rocks/sticks much better than the plastic ones. Both the discharge cover and bag seem to attach easily and solidly. It also makes it look more like a lawn mower and less like a big kid's toy.
2. Light (<55lbs). Since you're not carrying your power source onboard it will be lighter than any other mower in this size class (compare to 75-90lb for gas or battery electric). Larger rear wheels give easy maneuverability. Single lever height adjust works well and is spring loaded so you can raise or lower it with one hand.
3. 3 in one operation - A lot of electric mowers whether they're cordless or corded are limited on power, most get around this by using more efficient blade designs that generate less lift but mulching can be slower. With a reasonably well manicured lawn it doesn't matter much, but cut quality and performance drop off a lot if mulching tall or really thick grass. Since this model has a side discharge that remains an option for thick grass and improves cut speed significantly without wasting your clippings, quite a few electrics don't have a discharge option.
The bad?
1. Wheels/axles could be shielded a little bit so the cord doesn't tend to wrap around it and go under.
2. Mulching anything thick is slow, mowing through thick grass can take quite a bit of time (and tends to clump the output.) I think this is more related to the blade design, when you move fast through thick patches it will cut but leave a few standing, if it had more lift I think it would draw these up (and also help propel the discharge better). Unfortunately the blade seems to have proprietary mounting holes so that's hard to do.
Now, into the nitty-gritty:
This mower is powered by a brushed DC electric motor (Globe 7080). Brushed DC motors are lighter and cheaper than AC synchronous motors or induction motors. However they're generally less durable or efficient.
The Globe 7080 has a peak efficiency (their spec) of 68%. Peak efficiency at 3500RPM (590W output at 7.3A), Peak power at 2245RPM (860W output at 13A). Here's why that's a problem:
Mowers are generally limited (by agreement) to a maximum blade tip speed of 19000 feet per minute (for safety of items that may be thrown from the mower). Higher blade speeds give more lift helping the grass get lifted into the cutting path and making cleaner cuts. At max efficiency RPM the blade is moving about 17,800FPM on this mower. If you start cutting too fast you'll bog it down. Because it's electric it picks up torque so it will keep spinning but you don't hit peak power until about 11,600FPM. This is far too slow and you'll start seeing missed cuts and ragged lines (I noticed this in actual usage).
So since you can't really cut that slow, maximum usable power is closer to 600-650W, or less than 1HP. By comparison, a Honda GCV160 engine at 3600RPM (a common governer setting for push mowers) outputs about 3425W, falling to around 2800W at 3000RPM.
Obviously there are electrical supply limitations to a mower like this. It's perfectly serviceable but nothing amazing, if they ran a brushless motor in here it would undoubtedly cost more but the efficiency could be much higher (>85%) and could be designed for peak power much closer to the ideal blade speed.
Here's the specs on the motor, some were given others were hand calculated.

It has been two years to the date that I bought this law mower, I could not be any happier, besides the fact that in those 2 years, I do not know what is to deal with carrying fuel cans in my car, fixing clogged carburetors, changing spark plugs, oil, and air filters.
The only thing that I have done to this machine, is the occasional cleaning of the machine and keeping the blade sharp.
I gave it a five starts when I bought it and used the first day, I keep giving it the five stars.
Fist review 2014
Nice machine, light weight, easy to handle, a lot of power but it is not a self propel mower. Excellent if you want to keep yourself fit. Recommended if your lot is 25 ft in the front and 25-50 ft in the back. If you have 100 Ft lot get ready to drag a lot of cable.
The motor is a brush motor which means that is a high speed with a lot of torque.
Noise level is much lower than a gas engine mower, no fumes, no gas, no oil changes and no tune-ups. No need to store fuel in your garage or shed.
This mower is high adjustable and can be operated as a side discharge, allowing to cut a lawn that is too high.
Before you decide to buy a wired electrical lawn mower, you have to understand the issues related to the wire gauge of your extension cord.
Most of the failures associated with electrical lawn mowers, are due because the owner does not use the appropriate extension cord for the job.
First you must understand wire gauge AWG, the lower the number the thicker is the wire, so a 12 AWG cable is actually thicker than a 18 AWG cable, and a 12 AWG cable can deliver à higher current carrying capacity than a 18 AWG cable.
Below are the voltage drops for different AWG cables based on a length of 100 FT, but remember to take in consideration that the power outlets in your home are fed with 14 AWG cables, so in the sample below if you use a 18 AWG cable 100 FT, and the power outlet in your back yard is about 50 Ft away from the circuit breaker panel in your home, your total voltage drop will be 17 +3.5 Volts= 20.5 Volts that means that your lawn mower motor will be getting 99.5 volts, well below the rated 110-120 Volts it requires to do the job.
Furthermore, when the voltage drops it will increase the load / amps on the motor, which will overheat and stop or fail.
Cutting a lawn that has grown too high or is wet will increase the chances of failure if you are using the wrong AWG extension cord, the extra effort required to do the job will increase the amps on the motor and will overheat.
Using an old power outlet that is not weather protected in the outside of your home, could also give you problems. There is the possibility that the wires, and the power outlet may be corroded not been able to provide the extension cord with a good contact.
Do not connect / turn on other electrical appliances / high power demand devices in the same circuit you are using to power the lawn mower, it may trigger off the breaker in the electrical panel ( I said circuit, not power outlet, you may have several power outlets in the same circuit).
If the electrical panel circuit breaker is triggered off, that is a sign that you are doing something wrong. Unfortunately some times that protection may be too late, and the motor may have already burned out, the circuit breaker in the electrical panel is there to protect your home and you, but not the lawn mower.
Motors have thermal protections some reset after cooling off, some get damage and do not reset. Do not abuse the thermal protection of the motor, is not intended as an on and off switch, constant abuse will end in permanent failure.
If your lawn mower stops by the thermal protection, disconnect it and place it in the shade, let it cool off.
If the thermal protection worked, it should be able to start again, it may take up to an hour to cool off in hot weather, grab a beer and check the extension cord and outlet. Disconnect the extension cord and quickly check the temperature of the extension cord, if the cable is too hot, you are doing something wrong.
If the lawn is too high, place the wheels of the mower in the highest setting; use the side discharge feature of your mower if available. Read the owner's manual to check if you can remove the grass catch bag and operate the mower. Doing this will reduce the effort that the motor does to cut a tall grass.
Make sure the blades are sharpened and not bended, walk slow and give time to the mower to do the job. Learn to listen to the mower motor noise, so you know what kind of effort is doing. ALWAYS READ THE MANUAL.
The manufacturer recommends 16 AWG extension cords; I highly suggest that you use a 14 AWG if you are going to run over 100 FT extension cords. Avoid 12 AWG extension cords in 100 FT lengths; it is expensive, heavy and difficult to handle it for storage
The extension cord should have the AWG stamped on the outside insulation jacket.
Extension Cord Gauge AWG 12, 120 Volt, 13 Amps, 100 Ft, voltage drop 4.25 Volts, Electric motors receives 115.75 Volts
Extension Cord Gauge AWG 14, 120 Volt, 13 Amps, 100 Ft, voltage drop 6.75 Volts, Electric motors receives 113.25 Volts
Extension Cord Gauge AWG 16, 120 Volt, 13 Amps, 100 Ft, voltage drop 11.25 Volts, Electric motors receives 109 Volts
Extension Cord Gauge AWG 18, 120 Volt, 13 Amps, 100 Ft, voltage drop 17 Volts, Electric motors receives 102 Volts
Additional circuit inside home electrical outlet to breaker box
Home electrical circuit AWG 14, 120 Volt, 13 Amps, 50 Ft, voltage drop 3.5 Volts, deduct 3.5 from the above applicable values.
These values are for you to get an idea of the issues with long extension cords 100 ft +, you may only need a 50 ft extension cord, and the circuit for the power outlet in your home may be only 25 ft, so a 16 AWG extension cord as recommended by the manufacturer will be enough.

" Greenworks 21" Corded Electric Lawn Mower Review and Tips "
I have used it 4 times now to mow about 1/4 of an acre of St Augustine grass and it has performed consistently every time - even when the grass was pretty long the first time I used it. I've used it with the bag (which attaches very easily) with the mulching plug and, for a few minutes, with the side chute. All work well. I use the mulching plug attachment most since I believe in returning the clippings to the lawn.
Here's what I loved about this mower:
Weight: Our last mower was a gas, self-propelled Honda and even without the bag attachment it was getting to be a chore to use. This mower is not self-propelled but it is unbelievably light to move around. I usually carry the extension cables in one hand and push the mower in the other when moving from back yard to front and it is not a major effort at all. Our front yard has a slight slope to it and the self-propelled used to struggle with this, as did I, but this one is light enough to make that part so much easier.
Deck : The Greenworks line at this time has all metal decks. I was a bit concerned about grass clippings clinging to the underneath and resulting in rust and the manual does say that you need to wipe off the underneath after use to prevent rust. I have only used this when the grass is dry (easy in Texas) and every time that I checked the clippings had not clung to the underneath of the deck.
Exhaust: There is none!! I am sure our last mower was belching enough CO into the air to put me into a regular funk after lawn work. This one, obviously, has no exhaust and, I have to admit, there I get a kick out of the fact that I have stopped pouring fumes into the air every week!
Wheel Height: Adjustable one handed and glides smoothly. I love it after struggling with each wheel on our old Honda.
Start up: I must be getting old but yanking on the cord multiple times to get the gas mower going was becoming something I dreaded. This one starts quickly at the press of a button, is super quiet and I don't feel bad mowing at 8 AM if that is what I need to do.
And here's what I don't like:
Plastic screws: The screws that allow you to fold down the handle on the mower is connected using a plastic screw and lever system. I have my doubts that this will last very long since I fold it down after every use. However, I have little doubt that if and when it breaks I can come up with another system to keep the handlebar in place.
Deck size: While certainly large enough to not be a big pain, the fact that it is a few inches narrower than our Honda requires a lot more walking. BUT it is walking without fumes in your face and with a lighter machine so it does balance out.
Cables: This is a corded machine. I have read that using a certain grade of extension cord is important and the user's manual states this as well. I have one extension cord at the right grade and one that is a bit lower. The mower does fine when I have to double up the cords and use the 'inferior' one but if you want to follow the instructions to the letter you need to double check that. Also the cables are a pain the first few times you mow. I learned eventually to start close to where the cord was plugged in and always turn the machine in the direction away from the cord when turning around. Otherwise having to reorganize the cord was an absolute nuisance. Trees are a bit tricky but by the third time I had the method down and it was frustration free.
All in all, this is an excellent corded mower and I cannot recommend it highly enough!
Edit in August 2012: Still a great mower but the plastic screw in the handle fold down mechanism came loose and fell off while mowing. I've replaced it with a basic, but probably more sturdy, metal nut.
If mowing at the highest height possible (3.5 inches) it cuts St Augustine visibly unevenly. I keep it at 3 inches and all is good.
The cords are still fairly maddening. So if you don't handle frustration well you may want to look at a battery powered rechargeable version instead. I prefer not to have to eventually add a big battery to a landfill so I am still happy with my mower! :)
