"Look Ma! No MAN!" Perfect mower for a woman!
I am so happy with this mower! I do not need anybody to help me start it, no pull-cord start, and it runs smooth, reliably, and does everything a gas mower can do! We have a big yard, and one charge does the whole thing! When the neighbors saw me using it, I shut it off and yell, "Look Ma! No MAN!" and then pushed the button and off I went! It charges a lot faster than I expected. I wish Greenworks made a snowblower! That baby would be at the top of my list for this winter!

The Best Lawn Mower That I Have Ever Purchased
Ok let us begin with a few facts; this is not a paid review, I got no discount for agreeing to write this, the comments and photos are all mine, both the good and the bad. Let’s start off with the best feature first; 1. It cuts really well, and clean, no tearing of the grass. (Plus you can rear bag or mulch as it easy to change) 2. The height adjustment on the deck is super easy; one lever raises or lowers the deck to your cutting height. 3. Ease of Operation, push button starting, dual hand controls for cutting and amazingly easy to adjust the propelled speed. I thought the rabbit and turtle graphics should have been replace with just a simple S for slow and an F, for fast. 4. Starting gets a whole bullet point. THIS IS THE REASON I BOUGHT THIS. At 74, it was becoming nearly impossible for me to keep pulling on the starting rope, on the gas powered mower, sometimes as many as 20 pulls. It was so bad I had to think about never cutting the lawn again. Then my Son suggested this Green works Lawn mower, he said “Pops no pulling just press the button”. So I decided to try it. And I loved it so much a purchased the Green works Trimmer to go with it. It is really nice to enjoy doing my yard again, thanks in a large part to Green Works. I didn’t buy it to save the world, I had a somewhat selfish reason; I wanted a lawn mower I could start. Let us review the bad; The only bad; when this bad boy arrives it is one big and heavy box. So I had the driver place it on a moving dolly for me, which really made it a lot easier to unpack everything. Added Bonus: it stores in so little space in my garage. Sharing a few photos, Storage in the garage, front and back yard, right after cutting, (the hedges all cut with the Green Works trimmer) and KoKo Boy who loves the lawn right after its been mowed with my Green Works lawn mower. To answer the biggest question, would I buy it again? YES make that a double YES YES.

    Amazing equipment!
    This all started with the purchase of a Greenworks blower. Which then turned into the purchase of a Greenworks pro trimmer. After that purchase, and realizing the real power behind this fantastic pieces of equipment, I purchased a 21” mower. I couldn’t be more satisfied. I may not have a large yard, but with two 60V 4.0AH batteries, I’m able to mow, trim, and blow everything off and still retain half a battery. This equates to approx an hour to an hour and a half of run time. Better yet, no more trips to the gas station. No more messing with those ever changing gas can spouts, that cause more spills than anything. No more oils mixing or changing. Just two batteries on a charger, and roll. I look forward to trying out more of Greenworks products in the future!

    Going Green(works)
    I ordered my Pro 60v 21" mower on August 9th and it shipped almost immediately. I've used it a half dozen times since then, and I'm thrilled with the product. I love that I'll never have to deal with oil changes or gas refills - won't stink up the garage or emit harmful exhaust. The mower can take on the toughest of grass with the Turbo feature, and cuts consistently across the entire lawn. The self-propel feature is useful because it can be adjusted for different speeds. I typically set mine somewhere in the middle and it is a reasonable pace. It takes me about 45 minutes to do the front and back yard, and I usually only use up one of the two batteries during the mow, with using the medium self-propel setting and occasionally turning on Turbo mode if the grass is long in spots. As some other reviews mentioned, the charger fan is a bit noisy, but who cares, really? Plug it in in the garage and it'll have both batteries charged in 30-45 minutes. Storage is easy too, with the mower folding up to take up less space. I'm definitely going to get the trimmers and I'm hoping they'll have a shop-vac that runs on the 60v batteries sometime in the future. Oh - and one last thing - this mower is QUIET! I can have a conversation with someone while it is running without having to shout. I'll never feel guilty if I have to run the mower early in the morning or late at night!

      Better than advertised!
      I've only cut the grass twice so far but I am very pleased with my purchase! The battery is rated for 60 min but I think it could go 80!
