Greenworks G-Max Batteries

Greenworks G-Max BatteryOne of the most frustrating things about electric lawn mowers is that they just always seem to run out of battery too quickly. Well the Greenworks G-MAX 40V electric mower has found away around this frustration, and it really is such a simple solution.

Greenworks have been able to offer up to 70 minutes of run time  out of the G-Max 40v by using two batteries – at the same time!

It features a state of the art battery switching system, so that when one goes dead it automatically switches over the charged battery and you can keep mowing.

The batteries are of the Lithium-Ion type which means that you don’t have to worry about them building up a memory and losing their charge capacity.

There is one thing about the batteries that may be confusing to some people, the two included batteries are different. They both fit the Greenworks G-MAX mower, but they are different capacities. One is 2 Ah and the other is 4Ah. I’m not really sure why they did it this way, I guess it was a way to get the run time up to 70 minutes but keeping costs down.

Our only complaint when dealing with the battery system, is that the included charger only fits one battery at a time. This can be a bit frustrating if you do have a larger lawn to mow and you need to wait for two batteries to charge.

Out of the Box and Storage

If you are worried about there being too much assembly of Greenworks G-MAX 40v Electric Mower out of the box, then don’t. The setup is relatively painless and you can have it up and ready to go in about 5 minutes. Then you just need to charge the batteries of course!

The mower has a mulching plug that is pre-installed, you will need to remove this if you don’t want to use the mulching feature.

The procedure to store the mower is fairly simple, the handle folds up quickly and easily and it stores away nice and neat. The manual does recommend that if you are storing it for any length of time, you charge the battery at least every 2 months.

Greenworkds 25302 ReviewTwin Cutting Blades

The Greenworks G-MAX 40V Mower uses a twin blade cutting system, which we found are a great feature.

We also thought the mulching functionality was top notch, even when mowing over sticks and other items that fall out of trees – the twin blades make short work of it. With just grass, there are no visible clippings left anyway on the lawn.

A 20 inch cutting deck saves you time (and your legs) as well. Because it is a little wider than most of the other electric mowers on the market, so mowing your lawns will require less passes.

The single height adjustment lever means it is super easy to adjust the cutting height of your mower in one action. There is no need to adjust each wheel individually.

Feature – Auto Throttle

The Greenworks G-Max has a built in auto throttle, which automatically adjust power to the cutting blades so the mower is not working harder than it has to. This maximizes battery run time and will also likely likely lengthen the life of the electric mower due to it not running at full throttle all the time.

In theory, this is a great idea. However we found that the auto throttle can be a little slow to react when you hit a thicker or longer patch of grass. This meant that the mower would struggle for a few seconds until the auto throttle kicked in and powered up the mower. It’s more of an annoyance than a real problem, but it should be mentioned.

Starting the Mower

The mower is simple enough to start and includes a 2 stage safety feature to keep those little fingers and hands safe.

The mower requires the user to insert a key before the start button will work. you then need to pull the bail towards the handle and release the start button to get the blades turning.

Should You Buy It?

If you are after a Cordless Lawn Mower with advanced features that many competitors don't have, then the GreenWorks G-Max 40V Cordless lawn mower is for you. It certainly does not lack in power and it has a nice long run time which should allow you to finish most lawns in one go.
