[This review was collected as part of a promotion.] 3 rd year going strong. This thing is a unit it's chewed through tall grass and weeds and gargled chunks of storm debris and it just doesn't care. I haven't even sharpened the blade once. I just got it out to mow sections where repairs from the storm could have left more debris and I don't want to damage my 25 inch newer model. It chewed through 6-7 inch grass in mulch mode on height setting 3 and wouldn't quit and the grass looked even despite it all. I really just wanted the twin battery 21 inch but could only find the 25 inch twin blade. I really wanted self propelled and manual turbo control along with 2 battery ports for the extra energy used. I like the 25 inch it does pretty good so far, but that 21 inch model is strong and hard to beat. Also feels light as a feather.
Side discharge is the only weakness at that is highly dependant on when you mow and what settings. Unlikely to throw rocks and have to sweep grass though.
Pros: Convenient, Easy to Use, Quiet, Durable, Effective, Powerful
[This review was collected as part of a promotion.] I was looking for a replacement mower. I have seen this unit on my street, and reviewed its features. It’s impressive. Has either steel or poly surface, stores upright, silent mowing, two huge batteries. Fan driven charger, and charges within 20 min per battery. Great. Both slot into the mower at one time. Best of all, a 4 year warranty. It’s a well made and designed tool. Great design and strong.
[This review was collected as part of a promotion.] It hasn't function properly when handed over to authorized Greenworks repair station. I had an identical product installed a few weeks earlier and it works fine. So I ordered another unit to to replace a faulty speed assembly on a newer unit. I received a phone call from the authorized service repair shop stating that half of it works but the blade doesn't move. The repair shop has offered to contact Greenworks and inquire what the issue is all about.
No, I would not recommend this to a friend.

Hello Rick Bryant. Thank you for sharing the details of your experience with the upper mower assembly. Based on what you have described, where the unit powers on but the blade does not engage, this typically points to a connection, safety interlock, or drive engagement issue within the assembly rather than a complete system failure. Since the unit is already with an authorized service center, that is the correct path forward. They have direct access to technical documentation and can interface with Greenworks to identify what the issue is. Once Greenworks provides guidance, the service center should be able to determine the exact cause and next steps. Staying in contact with the repair shop for updates is the best way to ensure the issue is fully diagnosed and resolved. Should you require any troubleshooting, warranty assistance, questions or other concerns, please do not hesitate to contact us directly via chat or call 1-888-909-6757 (1-888-90WORKS). Thank you for choosing Greenworks Tools!
[This review was collected as part of a promotion.] I recently purchased this Greenworks 21” self-propelled mower and could not be happier. As someone doing this on my own, I needed something easy to manage—and this delivered in every way.
It was simple to transport home, quick to assemble, and I was able to start using it right away. The self-propelled feature makes mowing effortless—it really takes the strain off and makes the whole process enjoyable.
The mower is powerful, cuts evenly, and leaves my yard looking fantastic. I also love how easy it is to store—it folds up nicely and doesn’t take up much space in my garage.
This is a great option for anyone looking for something dependable, user-friendly, and efficient. Highly recommend!
