Product Overview

Experience the power, convenience and economy of a G-MAX 40V Li-Ion garden tool from GreenWorks.

This 3in1 460mm lawnmower is perfect for keeping your backyard trim and tidy without the hassle of fuel cans, oil and filter changes and chokes. Just charge up the 40V 4.0Ah lithium ion battery and get on with the job.

The 7 position height adjuster lets you easily change between 28mm up to 76mm cutting heights, while the 460mm steel cutting blade mechanism features an impact protection cut-out for safety.

The cutting-edge brushless motor provides more power, longer running time and higher speeds as well as greater efficiency and less noise, while the 50L catcher can handle plenty of clippings.

If you don’t want to dispose of your clipping it’s easy switching to side discharge or mulching modes, giving you plenty of options when it comes to handling your garden waste.

GreenWorks Brushless DigiPro Series is an innovative solution for your garden tasks that rivals petrol-powered tools. Combined with the 40V G-MAX system, the Brushless DigiPro Series features a powerful brushless motor that improves the battery efficiency, delivers more power for greater performance, produces less noise and vibration, and extends the life of the motor for exceptional durability.

Traditional brushed motors tend to wear down over time, reducing efficiency and power. With a brushless motor, you can expect the same performance as the day you purchased it. The gear reduction design of the brushless motor also delivers greater torque.

Greenworks Lawnmower

I have purchased the Greenworks lawnmower 1 month and a bit ago. I have used it a couple of times and I am quite pleased with the result. I only have a small lawn so the battery powered lawnmower works well. Big test coming as spring is around the corner :). I do like how the lawnmower powers up if you get into a thick batch of grass, and powers down when it is not as thick. One trick of new players. remember to push the button then pull the safety bar, and not the other way around. Otherwise it doesn't start and your wife looks at you in annoyance!

Easy mower to use and practical for those like me find it hard to pull start petrol mowers. One push and you’re off.

Purchased this lawnmower because of positive reviews internationally. Certainly happy I did. I can comfortably mow my lawn (700m^2 section)and still have battery charge left. Very quiet and light making it easy to maneuver.

Ticks all the boxes for our section, it’s the first electric mower I have owned and sure is easy to operate and store.

So far so good with this mower. The battery is enough for two separate mows (500sqm section) and it feels like it has a good amount of power. The mulching function is excellent, I can hardly tell I haven't used the catcher after mulching.

Super sweet mower

Owned for a month or so. First mow was slightly damp and fairly long grass and the G-Max just ate it up. The auto-speed controller kicks in when needed and the whole machine seems hassle free - no petrol or oil or farting about trying to get it to start, easy! The best feature has been the lack of noise, it doesn't frighten our toddler or require him to wear his earmuffs, so he's happy to 'help' with the mowing. The quality of the cut is superb and subsequent maintenance mows haven't taxed the motor at all, just a gentle hum. Managed the whole section on one charge, although we got a second battery for the line trimmer as well - which is also amazing, super powerful. Batteries are fast to charge. The ONLY thing I've noticed is that the wheels are quite hard so the ride is a little jolty but it's nothing a pair of leather gloves can't fix. So far so good on our pretty typical NZ section; fairly gnarly and rambling. While I'm at it, the TradeTested team have been great to deal with. Very happy customer.

Most practical mower for a suburban lawn

Exceptional performance and features for the price. This mower has taken the frustration out of mowing our lawns. It's quiet enough that I can actually enjoy the time outdoors, and I can even hear the neighbour's mower over it. The standard 4.0Ah battery lasts through cutting the berms and our 650sqm section, and leaves a little juice to finish the edges with the line trimmer. Its lightweight, which means I don't work up a sweat when rushing to do the lawns quickly. It also means I can build a deck between the garage and front lawn, and just carry the mower over to the lawn. Storage is easy. No petrol, and the mower can be sat against the wall, without worrying about flooding.

What a dream to start this rechargeable mower. It's quite a bit heavier than my old electric one but I no longer have to drag around a long power cord in order to cut my extensive verges so that's a definite plus. Three different grass discharge options is another great feature. It truly was a happy day when I saw the Trade Tested advertisement and be able to pre-order this wonderful mower.

Way better than I thought it would be. As much power as my old petrol lawnmower and the battery lasts longer than what it takes to mow the lawn. When the mowing gets a bit tough it automatically revs up. No need to use the catcher unless the lawn is over grown, the mulching system works great. It's quiet, no petrol, no oil, no pulling, just press the button and go. Fabulous!

Frustration free lawn mowing!

The GreenWorks lawn mower is so easy to use. With just a press of a button, pull back the lever and away you go. No petrol to worry about, no oil to run out of and no spark plugs to check. The cutting deck is as wide as my old petrol mower and gives a fabulous cut. I have 2 batteries and this allows me to cut all of my lawn in a little over an hour, which is about 10 minutes longer than the petrol version. I used to waste at least 10 minutes trying to start the petrol one or had to get someone to start it for me. This is frustration free lawn mowing for me. I am very happy with my purchase!

I am very happy with the new lawnmower. My husband sharpened the blades for me and I have enjoyed how light, yet sturdy it is. He thinks it lacks a little power, but I have been enjoying the ease with which I can cut the grass and enjoy a manicured lawn. The battery lasts long enough to do our average sized lawn and it is so much lighter and quieter than our old lawnmower.

After having no lawns for the last 12 or so years, I am absolutely sold on this mower, it's lightweight, and power really surprised me.Great!

An excellent mower which copes with my smallish lawn on 1 charge. Has a wonderful array of attachments to cope with users preferences. Being quite elderly I do find it quite heavy to handle but for a normal able person it's a breeze. Recommend as good value for money.

Does what it should (most of the time)

Generally a reliable and effective lawnmower. Battery life seems to be a bit weather-dependent, and sometimes a single battery charge doesn't cover our whole lawn (around 500 sqm), but after recharging there is never a problem. Apart from that, no complaints.
