Rated 5 out of 5 by from No surprises! It is everything I expected, and after about a dozen cuts still works as perfectly as the day it arrived. I love it!

Rated 5 out of 5 by from 40Volt brushless mower Very easy to use, even without self propelled function. 69 years young woman had no issues using. I chose this mower on reviews and it could be used with out engaging self propelled. 2 smaller yards and tree lawns..perhaps in the future the self propelled will come in handy. LOVE that it revs itself up for longer, thicker areas of turf!

Rated 5 out of 5 by from Easy-peasy! Absolutely the best substitute for the the gasoline powered lawnmower. This is quiet, easy to start, no fussing with gas and oil and trying to pull the starting cord. I love it!

Rated 5 out of 5 by from 40 v self-propelled mower. I bought this mower because my old gas mower was on its last legs (wheels). After using the Greenworks mower for about a month, I am very satisfied. It does a great job on my 1/2 acre lot, though it does require 2 battery changes. The 5 a/hr battery will do the front and side yards, but the back yard requires both my 2 smaller batteries. I have a large sloped bank in the back yard and my gas mower struggled to go up it since the drive wheels were on the front. The Greenworks mower is driven by the rear wheels and it easily climbs the hill. I am very happy with this purchase so far.

Rated 5 out of 5 by from A magnificent machine! Being older I appreciate the fact that the machine is lighter than my previous mower which was gas driven. It is easy to maneuver. It is quiet (I can listen to music with headphones) and, because it is electric, there are no fumes. It starts with a simple switch. High grass is no problem for it. I have been unable to find fault with it. This machine is a gem!

I own a 21" self propelled mower (2516402) from Greenworks. Is that machine a Gen 1 or a G Max? Can I use a G Max battery? I need a backup.

Asked by: Elisabeth
Hello Elisabeth, You may use any of our 40V GMAX batteries with this GMAX Lawn Mower. The higher the ampere-hour (Ah) rating is on the battery, the greater the run time will be.

Hi, Is the "self propelled" always on when the blade is engaged? or can the mower simply be pushed to cut like a normal, non-self propelled mower?

Asked by: push1
Hello push1, The self-propelled feature is controlled completely separate from the blade which means that it does not have to run at all times, you may use it as desired!
