We bought our first Greenworks a couple of years ago and had a problem pretty quickly. There was only one place in our area to get it fixed, so we took it there. To our surprise a couple of weeks later, a brand new mower showed-up at our front door. Love the fact it is light, less noisy and requires no gas or oil. Now two of my neighbors have purchased similar mowers as well as leaf blowers and trimmers. Great for the environment!

We love our 19" 36 volt mower but we can't find a replacement battery.

Battery life is long lasting.
Wanted to wait several weeks before I submitted a review for this lawn mower to better evaluate its performance. This mower is a great product worthy of serious consideration. I can cut the entire yard twice before recharging the battery. My yard is approximately 3000-3500 square feet and is entirely level with a fescue blend. It cuts as designed and the grass catcher works flawlessly.

Mower does not perform as advertised
Started out great. Bought through Home Depot just 3 months ago. After 2 months of use, the battery quits after 1/2 hour of mowing, switch to the other and the smaller battery quits after 10 minutes. Very frustrating. 1/3 acre of lawn, this should not happen

The Perfect Mower for Me!
I love my 19" 40V mower with two batteries. I'm a single gal and after years of almost dislocating my shoulder trying to get gas mowers started, I bought this mower. It's great! It does a great job and I have no complaints at all.

This little mower is a beast! Next to no maintenance, the only thing I do is clean under the deck if and when I mow wet grass. I have owned this mower over 1 year with not a single issue, just ordered 2 new blades today. I mow some tight trouble places in our pastures with grass at least 18 inches tall (probably not recommended by greenworks) and this mower handles it just fine.

Have had this mower 5 years now and we are still on the original set of batteries. We bought it for our vacation cottage and have never regretted it. Works well and is so easy to use!

Glad I bought it, but wish I had the bigger one!
I've had it for a little over a year. No complaints other than that they released a newer one (21 inch with folding storage that I wish I could exchange for! This was the only brushless model when I purchased. So I recommend it, but only if you can't afford the newer model.

About 5 years and still going
I have had this lawn mower for about 5 years now. One of my biggest concerns was how long would the batteries last. Well they have exceeded my expectations and are still going strong. My lawn is not very big but there were several times where the grass was very much overgrown. I was concerned at first but now it does not bother me to cut the grass when it is overgrown. I do have to go a little slower and may need to charge one of the batteries again but the advantages far outweigh recharging a battery. The fact that you do not need to buy gas change the oil in the lawn mower and the spark plug make this lawn mower a win-win

Why do these mowers come with 2 different size batteries but only need 1 or the other to operate? Also, what is the difference between a 40 V G-Max & a 40 V Lithium Ion battery?
