GreenWorks G-Max Mower: Pros and Cons From an Owner
About the GreenWorks G-Max Mower
We live in Cincinnati and have an average section. I've owned the G-Max mower for over a year now when our gas powered mower finally bit the dust. I've got to say I was pretty reluctant to buy a battery powered mower as I've owned gas powered mowers forever.
What changed my mind to a degree was my brother in law buying a G-Max awhile back and swearing by it. Don't get confused with you're ordinary electric motor powered mower - these 25302 mowers are way different.
What makes this GreenWorks G-Max really stand out is that its powered by two electric motors operating two 10 inch blades. Powering them are dual 40 volt lithium batteries. This gives you about an hour runtime but what we did was buy an additional high capacity battery so we've now got a total of two hours runtime. Actually I don't quite know why I did that as my lawn takes only about three quarters of an hour to mow - must have got carried away by the purchase. Anyway doesn't hurt to have a spare. My experience with battery powered drills is that the battery only lasts about two years anyway.
Great thing about the 25302 Twin Force lithium batteries is that there's no memory to worry about and the charge time is only one hour.
The G-Max I've found goes through wet grass nicely and has an excellent single lever height lever giving a range of 1 -3/8 to 3 3/8 inch lawn height.
It only weighs 45 lbs too - about half of what my old gas mower weighed. That means I can hang it on the wall now instead of it taking up valuable floor space.
Problems I've Had With the G-Max Twin Force
- The company website doesn't have much information on it and I still can't find an online manual for it.
- In really thick grassy areas the mower bogs down a little. It takes a little maneuvering to get through these areas - and you will go through a bit more battery juice doing it - but it will get the job done. In saying this my gas mower struggled even more in very dense grassy areas, so in some ways this is actually a positive.
- One of my batteries died after seven months but GreenWorks did replace this under a week and under warranty.
- Throttling - The G-Max 25302 Twin Force detects that its in long grass and so to compensate, throttles up - great feature, only problem I've found with this is that it takes a few feet of long grass before feature this kicks in so in that time it tends to die a little. It just means you've got to go back and mow that small strip of grass again. Maybe I'm getting a little picky here.

GreenWorks G-Max Good Points
The obvious great point is lack of noise. With my gas mower I was always conscious when mowing of the neighbors - Now with the Twin Force mower I couldn't care less. The noise is minuscule. Its also very light to push in comparison as well.
Now with modern lithium battery technology the dreaded memory is gone. In the past with a mower like this, unless the battery was completely run down, when charging, it they would never fully charge. No longer the case. Now you can fully charge it run it down to say halfway and fully charge again.
You can run the mower with either one battery installed or what I do is run it with two. In this way if you run out of juice on one battery it automatically cuts over to the spare without stopping.
Its lightweight, turns easily, folds up in a snap and takes seconds to switch between discharge/bagging/mulching.
The mulching is great. We've got some tall oak trees that drop copious amounts of sticks and acorns and the G-Max makes light work of all this stuff.
In comparison to my old gas mower I can now have a conversation with my wife without raising my voice. There's no smell and vibration of a gas mower. No longer after an hour will you have swollen hands from the vibration of a gas mower.
I'm thrilled with my GreenWorks G-Max. Apart from a couple of hiccups throwing the old gas mower out the door is a real relief.
I bought through Amazon because they offered free shipping and it was much cheaper than the local stores in our area. Plus it arrived in less than a week really well packaged and ready to go.
