Going Green! 40V Twin Force 20-Inch Mower, 390CFM Cordless Blower, and 13-Inch Cordless String trimmer.

Going Green! 40V Twin Force 20-Inch Mower, 390CFM Cordless Blower, and 13-Inch Cordless String trimmer.
I have to say I was skeptical when I decided to purchase these GreenWorks tools. However, I have to say I am very happy with my purchases and very impressed with the quality of the equipment. All three pieces of equipment were very easy to assemble; I did not need to use the instructions that came with the equipment. There are some things to understand about these three pieces of equipment. Compared to gas powered equipment mower, blower, trimmer are all very very light. The lack of significant weight can be misleading and interpreted as a lack of power, however, this is untrue as all three pieces of equipment perform just as well as any gas-powered equipment that I have used.
Pros and cons
The pros to all three pieces of equipment do not very significantly. All three pieces of equipment are light, easy to maneuver, and appear to be very sturdy. The mower mulches grass significantly better than most of the gas-powered mowers I have used. I noticed a significant reduction in loose grass that was clumped and blown all over the sidewalk and driveway. One feature I particularly liked was the ability to start and stop almost instantly. This came in handy especially with the blower when needing to change direction. Finally, one of the pros is that the equipment is less intimidating than gas powered equipment. My wife ran the mower and the blower with ease considering this was the first time she ever cut grass. My mother came with two batteries and a charger while the blower came with one battery and one charger. This combination gave me one four-amp battery and two two-amp batteries. I have a small yard but the four-amp battery and one two-amp battery was more than enough to cut my grass, in fact the four-amp battery was completely used and the two-amp battery only used one green dot. The trimmer is as nice as any gas-powered trimmer I have owned. I especially like the edging feature, which works very nice.
I cannot find too many cons to any of the equipment. Certainly, it takes time to learn how to work with new equipment however, none of the GreenWorks equipment appears to be overly complicated. I did read some negative reviews of the string trimmer. Understanding that you have to release the throttle and wait for the spool to click which indicates an advancement of the line is a key to understanding how to operate the trimmer. I find the included trimmer line is somewhat light and I will change it out once I use it all.
Recommendation
I would recommend this equipment anybody who desires equipment that is easier to work with and wants to move away from using gasoline. I would eventually like to try the snow blower especially here in Pennsylvania during one of our typical winters. In closing I will say this if you are on the fence go ahead and go green you will not be sorry.

Best thing to ever happen to my lawn

I've had it for two years now and it's still a work horse of a product. I have a very large back yard as well as front yard and 30 yard long by 15 feet wide grass on each side of the house. And the sidewalk grass on the front and side of the house because I have a corner lot. It gets the entire job done in under an hour for me. Gas mowers are ridiculous and I've cut to many cords on electric ones. Mower save souch time and I have battery power left as long as I cut my grass every two weeks
I had my doubts but now I am a believer! Great mower.

I was looking to replace my generic gas powered bagging push mower when I found this on Amazon. Pouring through the reviews I decided to give it a shot. With Amazon's return policy it was not of big of a risk.
Two days later it showed up on my front porch. Easy unboxing and the only assembly was attaching the handle with the easy release bolts. Starting is simply holding down a button while you pull the handle back to the grip. The mower then sounds like a box fan running on high. It cut my grass quite well. It weighs half as much as my old non-self propelled gas mower. The bag is super easy to empty. Simply put, it exceeded my hopes and I am quite happy with this purchase.

So far so good. I've used it around four times and its worked flawlessly. I use it to cut various places around the yard that I can't get too with the big mower and it usually takes 20-25 minutes and I have not had any problems with the battery quitting before I'm done. Also the grass I'm cutting is usually quite tall, I have the mower set at one back from the highest setting and tilt the mower back slightly if necessary to get started in each area. The battery charges quite quickly, usually under 2 hours. I notice some other reviewers have had problems after several months or the following year, so I'll keep my fingers crossed.
A Hidden Bush Hog

I purchased this product because I didn't want to fuss with gasoline, oil and everything that goes with typical gas powered lawn mowers. I hate yard work - immensely. The last thing I want is to be out there any more than I have to with a malfunctioning or faulty piece of equipment. I also hate spending a fortune on someone else cutting my lawn so I purchased a full set of GreenWorks lawn equipment on Amazon.
The results have been spectacular! In addition to hating yard work and being lazy, I am also rough on equipment. I'll give a human TLC but I expect to throw machinery at anything and watch it muscle through. If you look at the pictures attached you will see some of what I put my lawn mower through. The grass was up to the knees! Keep in mind that you can't just power through in a straight line. You have to be sophisticated at work it a little with the bag on but it will chomp it all down just the same.
So, if your lawn looks normal and just needs a little off the top then this mower will run with the best. Light, easy to handle and lasts a good while on a charge (I bought multiple equipment so I ended up with 3 batteries). If you are like me then this will also get the job done but know that the more you ask of it the faster the battery will drain trying to accomplish the task. On a standard size lot once I get the grass short (again!) I can hedge trim; weed eat the entire perimeter, driveway and walkway; mow front and back; and blow all hard surfaces on three fully charged batteries in 45 minutes.
