Rated 5 out of 5 by from Great mower Works like a champ. I'm very happy with this purchase!

Rated 5 out of 5 by from Impressive I had gas mowers. Then I got an electric mower. Happened to be at the pawn shop and spotted a Greenworks mower. They wanted 250. I offered 200 and got it. Came with 2 charges and 4 batteries. Two mulch bags also. My son has Greenworks tools and I had wanted one. What a great machine. It's the twin force 20 inch. I recommend Greenworks to everyone. Thanks for making a chore more pleasurable.

Rated 5 out of 5 by from Can take whatever I throw at it and keep on working! I bought the "Twin Force" mower in 2013 and used it to tame the acre of lawn on our new property. The battery life was great, no fumes from a gasoline engine and so much quieter! I have since been using that mower to keep meadow paths open and have never been disappointed. That mower has been beaten up and knocked around! While it no longer has the bright colour and snappy look it once had, I'm still pleased with it's durability and consider one of the best values in purchases for equipment on our 80 acre "Bogwood." I recommend Greenworks battery powered tools to all my neighbors and visitors who tour our property.

Rated 5 out of 5 by from I love the 20-Inch Cordless Twin Force lawn Mower It does an excellent job cutting grass. The best part is the twin batteries and you never run out of power. No need to run inside and charge the batteries, ever. The assembly was easy and customer service is great. I have been using this machine for two years and touchwood, no complaints. I would recommend this product, hands down:-)

My wife loves this mower. But she said it was cutting uneven. After investigating the number one motor is not running in the right direction. Can I reverse the wires to that motor. 

Asked by: SNOWbug
Hello there, Please know that the blades do rotate in opposite directions as shown in the following video link: https://www.youtube.com/watch?v=qr4n45JXhDo. The two blades are supposed to create a vacuum-like effect that pulls the grass to the blades to be cut which eliminates the possibility of a strip being left behind in between the blades. A sharp blade will greatly enhance the performance of the mower, especially when cutting high grass. Be sure to check the blades and to sharpen them or replace them at least once per year. Here are a few other tips to achieve a cleaner cut: 1) Set the mower to the highest cutting height (or 1/3 of the length of grass), mow no more than 1/3 of the total length at a time. 2) Ensure that the grass is dry when mowing. 3) Alternate mowing patterns each time you mow. As grass develops a grain based on your cutting direction it will lean towards the direction of your mowing path. Changing the pattern allows better vertical growth and helps to keep the cut neater. For best results keep the grass under 4" in length and walk at a slow but steady pace to allow the blades to cut efficiently. For further assistance, please give us a call at 1-888-909-6757 or send an email to info@greenworkstools.com.

Can I get this model, tool only. I already have a charger and battery

I just got the model 25302. In the instructions, it indicated the handles are ready to use, just unfold. The handles on mine are not assembled. Could you provide assembly instructions? It should be easy enough, but I want it to be correct. Thank you.

Asked by: bigal70
Hello bigal70, We are sorry to hear about this! The handles should be assembled as shown in the following YouTube video: https://www.youtube.com/watch?v=MxSlBpQv2S0. However, if they are not, you would just have to unscrew the top portion of the cam lock, put the handle in place, and reinstall it. When unscrewing, you are actually going to be unscrewing the handle lock which is the handle that locks/opens. If you require further assistance, please contact us directly at 1-888-909-6757 or via email at info@greenworkstools.com.

Why does it only drain one the smaller battery and never touch the bigger one and I can’t get it to run without both and it only lasted about 25 min on a small yard 

Asked by: Camcammyguy
Easiest way to trouble shoot. Put in one battery and try to start. Switch battery to other compartment and try to start. Do same for second battery. This will help determine if it is the mower or battery that is having issues. Make sure both batteries and fully charged, this battery has a battery level indicator we suggest always checking it after removing battery from the charger ensuring all four (4) green indicator lights are illuminated indicating the battery is at full capacity. The charger lights should appear red and green when the battery is placed on the charger and switch to green and green when it's fully charged. Make sure that when you put the battery into the charger that you hear an audible click, and the battery cannot slide out if the battery is not secured it will not charge. If you leave your charger plugged in always unplug and reset, it. Chargers are not recommended to be plugged in for prolonged periods of time. If this does not resolve the issue, we would like to trouble shoot this issue further with you. Please contact us on info@greenworkstools.com you can always speak to a Customer Care Specialist at 1-888-909-6857
