Size: 40V 12" + 390CFM (2.0Ah)
I like this a lot. I didn’t realize how much lag or spooling up you have with gas-powered tools. You press the throttle and have to wait a second or two for it to be fully up to speed. With electric, it seems like it’s spinning at full-speed just as soon as you think about it much less press the throttle. It’s really nice and I didn’t know how annoying it was before until I tried electric. Anyway, this tool specifically has its weight well balanced so it’s easy to maneuver. The controls and touch points work well and feel ergonomic. The shaft is plenty long for a taller dude (I’m 6’2” and it’s plenty comfortable). The trimmer has plenty of power. I used it to not just trim the grass that had been growing for a while, but also to “push back” the soil that had migrated on top of my driveway and it worked fine for stirring all that up, so I could clear it with the blower. The blower could use a little more power. I was able to clear everything from the driveway, but you just have to use a little patience. Battery life was no issue at all. I have a smallish lawn, but it was a little overgrown, so it had to do a lot of work in cutting back the growth and blowing the trimmings away. It handled that with no sign of slowing down. I’d say 90% of homeowners will be a-ok with this battery. I'm posting this review after only one use, so I can't comment on longevity/durability. ======== Update: After nearly 8 years of use, the both tools continue to work, I'm still on the ORIGINAL battery!!, the battery still has enough storage capacity to do my lawn with both trimming and blowing. I've had to replace the charger once. It shorted out somehow. No big deal. Overall very pleased with how well it has held up. I've had to replace the caps for the trimmer head numerous times. That's ok, though. Kind of to be expected. Biggest beef is with the line feed. It doesn't feed at all no matter how you load/bump it. I have to stop every time I need to feed line, which means that I'm stopping every several feet. Very annoying. For that reason I intend to upgrade the trimmer, but it's still functioning ultimately. Still very pleased.

Does exactly what it says it should do. I have a big backyard, it's a pain to mow it without weed whacking before hand. After fixing the thread twice it worked like a charm, cut down most of my wannabe forest. I did get about 40 mins of work from it. It's not as light as you think and I couldn't adjust anything on it to make it feel less bulky but, it got some of the job done ( my yard takes me on average about 3 days to complete ).

I recently replaced my 15-year-old gas trimmer with this cordless unit because I was tired of trying to keep the gas unit running. This is my first experience with a cordless model. I'm still getting used to it, having used the trimmer only 3 times so far. It seems to work quite well, although maybe not quite as powerful as my old gas model. I have a 1/2 acre of property, which probably includes at least 500 feet of curb, sidewalk, driveway and flower bed trimming. The first time I used it I walked quite fast and was able to trim everything reasonably well plus use the blower on all edging except the flower beds before the recharge light came on. This set came with a 2.0 AH battery, but since then I purchased a 6.0AH battery to make sure that I always had an adequate source of power to complete the job, at a slower pace. I initially had a problem trying to assemble the blower tube, but after a few minutes was finally able to put the lower tube on. I've had a problem with the trimmer string, in that on several occasions it partially welded itself on the spool. I've purchased a can of silicon spray, have sprayed the spool and so far the string appears to be playing out as it should. For what it's worth, with the 6.0AH battery, the trimmer weighs about 8 pounds and with the 2.0 AH battery it weighs about 7.5 pounds. My old gas model weighed about 10 pounds with a full tank of gas, so being that I'm almost 80 years old, this is a bit easier to tote around. The blower does a decent job of blowing debris away. I would recommend this combo to other customers, and I'm hoping my "fix" to keep the string playing out will continue. Update - After reading another customer's review, and looking at a picture of the blower, it was obvious that my tube was at least a foot shorter than it was supposed to be. Why was that? On closer inspection I discovered a tube located inside that one. (It had been jammed inside and took a little effort in removing it). However, after removing it, it was then easy to assemble the tubes, and with the partial "obstruction" removed, the air velocity was greater.

The blower and the charge time on the battery were the best parts. The blower seemed to clear the debris easily and the battery completely charged in what seemed like less than 30 minutes. That was impressive. The trimmer, in my opinion, was trash. The trimmer had plenty of power, thanks to the 40v system. But where it lacked was the operational control, ergonomics and last, but most important of all, the trimming feed system. The handle was not comfortable for the way I hold/use it. The buttons/control handle are awkward and the he safety switch is in a terrible position and is awkward to press. I kept having to stop, reorient the he trimmer to get a bearing on where I’m holding it and reposition my hand to press the buttons. The final and worst part of this trimmer is the feed system. It uses so much line, there is not only unused line that gets cut off and all over my yard, but it depletes the spool rapidly. I mean, less than 50 yards of trimming and I had to reload. Thought maybe it was wound incorrectly or maybe my technique. Tried another spool and same result. Tried a third spool and changed my technique. That seemed to make the biggest improvement. But I barely made it to 80 yards before I had to reload. I’m just grateful Amazon is an amazing company. They are allowing me to return this item, even after I used it, without any issue or problem and the item was delivered and picked up for return in a very timely process. All in all, if you don’t do alot of edging and just need some simple weeds trimmed, you his maybe should be kit for you. Otherwise, I would steer clear from this particular combo kit.

Let's start with the items I think stand out: 1. One of the key features for me is storage. I'm a recreational cyclist so my garage is full of bikes leaving little room for lawn equipment. The Greenworks equipment stores vertically against the wall in a area of the garage not normally occupied leaving the area where I keep my road bikes free while not interfering with vehicle parking. This also may be appealing to those that like me have a standard garage but full size trucks, SUV to fit inside. 2. As this equipment has no gasoline in it, you are able to transport it inside your vehicle without the danger of exposure to explosive and toxic fumes. This combined with the mowers already compact size mean you have many options for transportation. 3. Of all 3 items only the trimmer requires servicing to replace the trimmer string and in this way it is exactly the same as gas powered unit and the trimmer string is a generic standard string I purchased at Wal*Mart. 4. I use the second battery for the mower to power the trimmer. I could and sometimes do use the lower amp/hour battery that came with the combo and do when the yard is particularly thick or tall. 5. The trimmer operates like a traditional gas unit and dispenses additional string each time the trimmer is activated by the user. 6. All 3 devices have safe start buttons to insure deliberate activation and reduce the possibility of accidental activation of the device. 7. Speaking of reduced, another key plus in my book is the substantially quieter operation. The mower is not much louder than a household vacuum cleaner. Allowing me to mow much earlier in the day while it's cooler without disturbing my neighbors. 8. The mower make a reasonably effective cut but does require 2 passes to accomplish this. I think this may be a limitation of the blade speed. The mower does increase RMP when it hits a certain resistance threshold. The higher speed will help you get through a more dense patch of lawn and will maintain that speed until the resistance drops below the threshold. 9. I bag my clippings but attachments were included with the mower that would allow for either ejecting the clippings out of the side or mulching. My front yard is a mixture of fescue, and buffalo grass and grows quite densely and the mower does have to work to cut this area. The sides and back are mostly buffalo and are fertilized but not watered 10. The combination of all areas including the ally is 2,600 sf. and used to require approximately a 1 gallon of gasoline a month to maintain with a gas powered edger and mower, and fuel oil mixture for the string trimmer and blower and the inconvenience annually of servicing the motor oil and spark plugs. Comparatively it cost pennies a month to charge the batteries with a substantially reduced mechanical footprint and no physical exposure to fuel or oil. Additionally fumes escaping from gas equipment and containers no longer contaminate the living environment of the house through the garage. 11. Now lets consider durability. I have been using this group of Greenworks equipment for over 1 year now with the same batteries that came originally with the equipment. I have experienced no failures or defects. After 2 mowing seasons the battery life has met my expectations of reliability. This was the most important aspect to me because if the batteries died prematurely it would completely negate any operational cost savings. 12. Aesthetically the mower has been style to have to outward appearance of a traditional gas mower and while this may not be of particular importance to me personally, some may feel that it is a selling point. 13. Now let's talk initial cost. In 2006 I bought a full set of Yardman gas equipment totaling $1,300 and it would cost even more to buy that equipment today. The Greenworks equipment totaled $550 making its up front cost a considerable value if reliable. 14. Care for this equipment is not totally without effort. Once a month I routinely wash out the bottom of the mowing deck to insure clippings flow effectively to the bag. The lack of heat from a combustion engine seems to preserve the painted finish allowing the deck to be completely cleaned to a almost new state and I have not seen any indication of chipping or rust. 15. Despite regular use the cutting blade has remained sharp and has not required sharpening. 16. The blower works every bit as effectively as a gas powered blower but is perhaps the loudest of the 3 pieces of equipment. I have always been able to mow my entire yard on a single charge of all 3 batteries but a yard larger than maybe 3,200 sf. would likely require additional batteries which can be purchased separately at a cost of $119.99 each. In conclusion for my size and type of yard, the Greenworks equipment has been a very good solution for my lawn care, and I highly recommend this gear. Who wouldn't I recommend this gear for? I wouldn't recommend this for someone who has a lot if tall brush or rough cut obstacles that have to be routinely traversed. This is not a heavy or brush cut solution.

VERY user friendly! Assembly was also very simple. My only issue would be the battery lasts maybe 40 minutes, but it is rechargeable so it’s a small thing. I was never one for yard work, so this is perfect for anyone who is the same!
