Powered by the GreenWorks G-MAX 40-volt lithium-ion system, this mower features a dual blade design for higher cutting efficiency, utilizing two 10-inch metal blades (offering a 20-inch cutting deck). For enhanced cutting capabilities, this mower also features dual motors to operate each of the 10-inch blades and a dual battery design to increase run time. Get up to 70 minutes of run time with the G-MAX 40-volt high-capacity 4 Ah and low capacity 2 Ah Lith-Ion Batteries (included with purchase). Adding an additional G-MAX 40-volt high-capacity 4 Ah battery (sold separately) gives you almost 2 hours of run time. You can operate the mower with one battery at a time or with two fully charged batteries for efficiency, power switches automatically to the next battery for ease of use.

Super quiet, super light, very easy to use.
Christian Billet
I get well over an hour's worth of mowing from a full charge of both batteries - more than enough to mow my lawn (lot is .4 acre, but only about half of that in lawn).
T. Rottmayer
They sell other mowers with different batteries, but I highly recommend to never buy anything that isn't lithium.

Size Name: Twin Force 20" Deck Verified Purchase
My wife and I wanted a mower that wasn't as loud and noisy as a gas mower, didn't require burning oil, and didn't vibrate as much. This mower fulfilled all of our wishes. We have a 1/3 acre lot, and this mower with two batteries works just fine. The only time we need to recharge the batteries half way through mowing is when we wait way too long between mowings, and the motors need to do some extra work to chop down the tall weeds. This mower is fairly easy to push, since it is much lighter weight than a gas mower. We also bought the electric trimmer that uses the same battery system, so we were sure to buy that kit with an extra charger and battery. Sometimes we use the extra battery, but it is nice to have just in case. Overall, I would buy this again and am quite satisfied.

Update 5/17/2014-
Still using this mower all the time, and it still works great. I've taken to only using one battery at a time, and keeping the other on the charger while mowing. Not sure it makes a difference, but I like it anyway to take a little break while mowing to switch batteries. When done mowing, I do tip the mower on its side and clean the underside. Some more expensive mowers have a water hose attachment to clean the underside, but I'm not sure I would spray water into the motor on this unit. :-) Using a stick works just as well, and seems to keep things working better.

Greenworks 25302 Twin Force.

Pros

Very cool looking and lightweight. Nice hard case clippings bag (but a little small). Nice easy height adjustment. I cannot comment on the longevity of the batteries as I have only had this mower a very short time, however as received they worked really well, charged quickly, and from a battery technology standpoint this seems to be a well executed concept. Auto battery selection while mowing is seamless.

Cons

If you like a well manicured lawn this is NOT the mower for you. On regularly mowed normal height grass it produces a very ragged cut, even after several passes. If you have a need to mow anything taller than normal grass (edge of cutting area, high grass, weeds, or plants) it will only flatten them down and pass over them without cutting them. If it manages to cut them it will not mulch them or collect them. Basically anything tall does not cut easily or mulch. Twin blades simply do not compare to single blade mower. Blades actually do not overlap to produce a clean 20" cut. What you basically have are (2) 10" trimmers with hard blades under the deck working side by side.

Safety toe guard is very flexible rubber, is way too flexible, and way too short. When mower is moved backwards it immediately folds right under the deck and offers NO PROTECTION from rolling back over your toes. If this was a normal full bladed mower I am sure it would be damaged by blade contact. This is an important safety feature and is something I have seen in independent reviews on the net. The company must be aware of if it, even if it only performs cursory product reliability and design tests, and has chosen not modify or improve.

Size Name: 16" Deck Verified Purchase
I needed a lightweight, small lawn mower for the trim around my house. II was hoping this small, lightweight product would do the trick, and it does. I wish I could say I purchased this product to help the environment and save the whales, but I was really just looking for something that would be easy to use, require little maintenance, and be small and not take up too much room.

Pros:

- Small, lightweight
- Very maneuverable to get into the small places my riding mower cannot
- Wide range of height adjustments (issue with the previous model I think)
- "Senses" deeper grass and speeds provides more power for such situations. I know someone complained about this, not sure why. It's a simple approach but effective.
- Quiet. It's about as loud as a fan.
- Easy to use. It was ready in 5 minutes (plus battery charging time). I did have to read the starting instructions (push button, pull bar) because I was just pushing the button and it wasn't starting at first.
- Battery life: for me, this is just trim work around the house. I can use it 3-4 times before having to charge the battery again.

Cons:
- The handle connection at the base of the mower seems a little flimsy, hopefully it will hold up over time
- I wish they provided better instructions on the battery....should I charge it when it is fully discharged? Should I charge it after every use? Does it matter? I've opted to charge it when it is almost fully drained, hope that is OK. (It's also possible they did provide instructions but in my limited scanning did not see such comments).

Overall, I could not ask for much more. No longer do I have to keep a gas-powered mower around for the light work around the yard. I can't comment on how this would work for full-sized yards, but as a trimming mower it is absolutely perfect.

Quality control issues. Same defect on two of these. Broken / bad weld on assembly that raises and lowers the mower. Had to to return twice. Very disappointed as the lithium batteries and the light weight of the mower seemed like a winner. But lack of quality at such a high price is not a good sign at all.
