Product overview

The GreenWorks DigiPro 16" cordless chainsaw is the first petrol-comparable chainsaw and offers powerful performance and easy handling to make heavy duty jobs simple - all without the hassle of petrol.

Note: This tool does not include a battery or charger, these must be purchased separately.

Cleaning up your garden has never been easier. The strength and revolutionary design of this chainsaw will ensure durability and a smooth, precise cutting experience. There are no pull-starts, fuel mixing, or harmful emissions to worry about, just juice up the battery and get on with the job.

The ergonomic design means a well-balanced tool for superior cutting, meaning the DigiPro chainsaw is a great choice for pruning, while the over-mold grip handle and wrap-around handle ensure comfort, with safety taken care of by the large hand guard and chain brake.

An LED battery level indicator light makes it easier for the operator to determine battery life, and the translucent oil tank offers clear view of oil reserve to ensure the 16” bar and Oregon chain are kept lubricated for sharp cutting. Tool-less chain tensioning makes for quick and easy adjustments.

Powered by the interchangeable G-MAX 40V Lithium-ion battery system which delivers longer run time, higher performance, and greater output on all G-MAX tools (battery and charger sold separately).

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.

Revolutionise your power garden tool arsenal with the amazing G-MAX DigiPro Brushless 16” Chainsaw and 40V battery system today.

q: Kia ora, I have purchased one of the above chainsaws and would like to purchase a chain file/jig for sharpening the chain and some chain lube, could you send me a link for both if you have them please?
a: We don't sell files at this stage, however there are plenty available online or locally from specialists. You need one for a 3/8" chain. We sell Synforce Chain & Bar Oil, if you look at the 'Frequently Bought Together section above it is listed, or just search 'Synforce' on our website.

Impressive little saw

about 1 month ago


I bought this saw after seeing some really good reviews, and it sure lives up to it's reputation. Really easy to use and makes short work of small trees, the 4.0Ah pack lasts longer than i expected, cutting down a decent size tree and reducing the whole thing into firewood size chunks on a single charge (I think the 2.0Ah would be a bit small). Overall a very impressive little package. I went and bought the polesaw immediately after as I was so impressed.

I was concerned that a battery operated chainsaw would not perform - I am very happy to say it is brilliant plus it is lighter than a petrol equivalent. It is also very quiet so far less noise invasive to neighbors.

Great battery chainsaw

Have bought this to use on our farm for cutting up firewood and felling small trees. Has worked like a charm, plenty of power, simple operation and low noise. Love not having to pull cord to start and no petrol! I do recommend getting 2 or more batteries and perhaps the fast charger if you are wanting to spend a day doing firewood as it goes through the batteries quite quickly when you're dealing with large logs. Seems well constructed and sturdy.

Was never sure they would work as well as they should. How we took the plunge and purchased this chain saw. Fantastic, have used numerous times on small trees and branches. Even took off a branch that was 30cm diameter. Will purchase more in this range
