Let’s take a closer look at what the GreenWorks G-MAX 20” Cordless has to offer and how it can benefit your toolkit.

It is not too much to ask for both strength and environmental sensitivity together in one complete package, especially when it comes to the growing market featuring cordless, battery-operated lawn mowers. GreenWorks steps up to the plate with their 25302 G-MAX 40V Twin Force 20-Inch Cordless Lawn Mower, a machine that not only uses intelligent adjustment to react to the thickness of your grass but also has the power and follow-through to chew down tough situations. Avoiding smelly emissions from a gas engine is better for you and the environment, cutting down on stink, pollution, and saving time and money on maintenance and storage needs. When it comes to a mid-sized space, you’re looking at a win-win situation with the GreenWorks 25302 G-MAX Cordless Lawn Mower. While for many homeowners, switching from traditional gas to electric, especially battery-powered, lawn mowers might be a jump, there’s a chance you’re already prepared to make the switch.

DESIGN & BUILD | Simple and Green

The Twin Force title does not just refer to the powerful dual blades that make up the G-MAX’s 20” cutting deck. The GreenWorks 25302 G-MAX utilizes two batteries, 4Ah and 2Ah, for a total of 40V to ensure constant, fluid power for a clean, easy cut. It also embraces a 2-in-1 feature that allows it to mulch and bag as well, making it a pretty versatile option for homeowners looking for a device that will give them more for their money. Cutting height is adjustable as well, giving five different heights between 1 3/4” and 3 3/8″ at the touch of a single lever. All that and more packed inside a sleek-looking black and bright green package that just looks snazzy with or without the hard-top rear bag.

“…a huge advantage for some homeowners who are in a position to replace their old tools…”

The battery system on the G-MAX utilizes GreenWorks’ G-MAX 40V Li-ion System, a range of batteries and compatible tools that allows you to swap packs between a wide range of applications, from your lawn mower to string trimmer to a chainsaw. This can mean a huge advantage for some homeowners who are in a position to replace their old tools or are already using the system. These batteries are rated for up to 2,000 charge cycles, have a low discharge rate while still outputting full power during use, and are Energy Star Rated for efficiency and environmental friendliness. Plus, with no memory effect, you don’t have to be concerned about damaging your batteries depending on charging habits.

SAFETY & DURABILITY | No New Surprises

The GreenWorks G-MAX cordless lawn mower retains all the industry standard safety features a traditional gas mower has, especially the quick-disengage safety bar. Save your back the trouble with a simple electric push-start, and save your lungs and clothes from nasty gas emissions. Save your fingertips and tools by avoiding traditional maintenance concerns like gas flushes, oil changes, and filter replacements. That said, the same common sense safety measures still apply. Wear safety glasses and gloves when using any machinery, and stay aware of your environment.

“Save your fingertips and tools by avoiding traditional maintenance concerns like gas flushes, oil changes, and filter replacements.”

Being electrical, the G-MAX cordless lawn mower features fewer components that require upkeep, meaning there’s less to go awry. If something does go sideways, a four-year warranty protects your system against defects that may develop through normal use. The lithium-ion batteries come with a two-year warranty against defects in workmanship and materials. GreenWorks is more than willing to work with owners in efforts to maintain and extend the lives of their mowers, making your dollar go further.

Ease of Use

No pull starter, no oil changes or worrying about bad gas, no need to check the fuel filters. Seems too good to be true, right? The GreenWorks 25302 G-MAX cordless lawn mower really is that simple to use. Designed with 10” rear wheels and 7” front wheels, you’re looking at a device that is maneuverable, extremely lightweight, and strong enough to make short work of a typical summer day’s chores. If you have a larger space, or thicker grass that uses more power, you might need to consider the second set of batteries, or at least a third, to swap in as you go. When you’re ready, all you have to do is lock in the batteries, push to start and go. When you want something that is going to simply work when you want it to, the G-MAX cordless lawn mower is going to be a great place to start your search.

Best Features

GreenWorks innovated with the Smart Cut Technology, a system that adjusts power output and runtime depending on what kind of a task you’re up against. What this means is, if you’re chewing through thick snarls of grass, the mower will adjust appropriately to make sure it gets cut down to size. If you’re simply taking a little off the top, the mower will promote a longer runtime so you can get the little clippings taken off and redistributed with ease. The downside to this technology, however, is that if you come up against consistently thick grass, you may need to pause mid-cut and recharge or swap out. It’s a great idea, and it works well for homeowners who keep up a constant rotation, but it might become a bit of a drag for those who find themselves fighting with thick grass on a regular basis.
