Best Greenworks 40V 16 Inch Brushless Cordless Chainsaw
As an Amazon Associate we earn from qualifying purchases.
A search for best greenworks 40v 16 inch brushless cordless chainsaw points to one product: a 16-inch Greenworks chainsaw with a brushless motor, sold with a 40V 4.0Ah battery and charger. The listing says the bar and chain handle trees and limbs up to 28 inches in diameter, and it names storm cleanup and firewood splitting as uses. Those are claims on a seller page, and this post treats them that way. The listing gives a chain brake, a low-kickback design and a 3-year tool and battery warranty. This post covers what the listing states, what it leaves out, and when a smaller saw is the better buy.
Quick answer
- The listing describes a 16-inch bar and chain on a 1.5kW brushless motor. The 40V 4.0Ah version comes with a battery and charger.
- The listing says the saw handles trees and limbs up to 28 inches in diameter. The listing gives no conditions for that figure, and this post does not verify it.
- The listing gives an item weight of 10.4 pounds, a chain brake and low-kickback design, and a 3-year tool and battery warranty.
- Skip it if you need a runtime in minutes, a verified 28-inch capacity, or small-branch pruning, where a smaller saw fits the job.

Who it suits
This saw suits a property owner who cuts large limbs, clears storm debris and cuts firewood-sized rounds from a 16-inch bar. The listing names those jobs, and its bar length is the reason to choose a 16-inch saw over a 10-inch or 12-inch one. The product description calls the saw gas-free. It does not compare the saw with a gas model on runtime or power, so treat the gas-free point as a description, not a result.
It also suits a Greenworks 40V owner. The listing says the 40V platform works with Greenworks 40V tools, so a 4.0Ah battery you already own may run this saw. The listing does not say whether a battery of a different size fits, and it lists other battery sizes only for the 18-inch variants, which this post does not cover. Check the battery size before you buy a second pack.
The listing says the saw has a built-in automatic oiler and tool-free chain tensioning, which matter on a 16-inch chain that you adjust in the field. Adjustments still need care. The listing does not describe the tension check itself, so the manufacturer’s manual is the place to confirm the steps.
If you already run Greenworks 40V equipment, the platform link is the strongest reason to look here. For the same battery line in other tools, our Greenworks 40V electric lawn mower guide covers a different tool on the platform. Where the job is reach rather than bar length, our pole saw comparison looks at extension-pole models.
Before the first cut
The safety guidance applies at any bar length, and heavier work with a 16-inch bar makes the rules below worth following closely. Penn State Extension states that “Kickback is a leading cause of chainsaw-related injuries.” It also says that “The chainsaw should be equipped with safety features such as a chain brake, throttle lock, and anti-vibration systems.” The listing’s bullet names a chain brake, which is the feature that extension guidance asks you to check.
Oklahoma State University Extension gives the first rule for this saw: “Make sure the chain brake is on.” The second rule is “Keep both hands on the saw.” The same article explains the risk: “Kickback occurs when the rotating chain hits a solid object or the chain is pinched in a cut.” The Agricultural Safety and Health page adds a grip rule: “Hold the saw firmly with both hands using an encircling grip.”
The listing describes a low-kickback design. Cornell Small Farms states that “These devices will reduce but will not prevent kickback.” A low-kickback chain lowers one risk; it does not remove the need for technique. Cornell also says “Watch the guide bar nose. Do not let it touch logs, branches, or the ground when the saw is running.” That rule applies to any bar length.
The Agricultural Safety and Health page also describes “Chain brakes, a feature of gas chainsaws, reduce the risk of injury, if activated, by stopping the saw’s chain immediately if kickback occurs.” That line describes gas saws, so it does not prove how this battery saw’s brake works. Confirm the brake’s operation with the manufacturer’s manual before first use.
For face protection, the Agricultural Safety and Health page says to “Wear either a full-face shield or safety goggles or safety glasses with side shields to protect your face from flying wood chips, twigs, and sawdust.” Penn State Extension adds that “Avoid cutting above shoulder height: Overhead cutting increases the risk of kickback and recoil.” Keep the saw below shoulder height, since the extension guidance warns about the risk of overhead cutting.
Chain condition matters on a long bar too. Penn State Extension states that “Sharpness of the chain: A dull chain requires more force to cut and is more likely to cause kickbacks.” Keep the chain sharp, and use the listing’s automatic oiler as the listing describes, with the manufacturer’s manual as the reference for oil and maintenance steps.
Skip it if
- You need a runtime in minutes. The listing describes “extended cutting time” and holds charge for 12+ months, but it gives no minutes and no cuts per charge.
- You need the 28-inch figure to be verified. The listing states it as a claim, with no conditions, and this post does not confirm it.
- Your work is mostly small branches and pruning. The listing describes the saw for heavy yard work, storm cleanup and firewood, so a smaller saw may be the better fit for light cuts.
- You need the 18-inch variants. The listing shows 18-inch tool-only, 5.0Ah and 8.0Ah options. Those are not covered here, and the figures in this post apply to the 16-inch kit only.
What the listing does not say
Runtime and cuts. The listing says “Extended cutting time” for the 4.0Ah battery, and it says the battery “holds charge for 12+ months.” It gives no minutes of cutting time, no cuts per charge and no charge time.
The 28-inch claim. The bullet says the bar and chain handle trees and limbs up to 28 inches in diameter. It does not give the wood type, the cutting method or the condition of the bar and chain behind that figure.
Horsepower. The spec table prints 160 with no unit. This post does not use it, because a number without a unit cannot be compared with another saw.
Chain speed and oil capacity. The listing gives neither figure.
Battery size options. The 16-inch kit uses a 4.0Ah battery. The listing’s options include 5.0Ah and 8.0Ah batteries for the 18-inch variants, and it does not say which of those, if any, is a supported option for the 16-inch kit.
Storage advice. The product description tells the owner to store the battery pack in a dry, room-temperature place and to remove it from the tool before storage. It also says to use only the corresponding Greenworks charger and not to use a cracked or overheated battery or charger.
Warranty terms. The listing says 3-year tool and battery warranty. It does not give the coverage terms or how to make a claim.
How we chose
This post covers one product. Its ASIN is B00DRBBRU6, and the listing is titled Greenworks 40V 16″ Brushless Cordless Chainsaw, 4.0Ah Battery and Charger Included, Black/Green. The listing was read on 2026-10-23. Only its title, bullets, specification lines and product description were saved. Shopper feedback on the page was not recorded and is not used in this post.
The listing shows several variants, including 16-inch tool-only options and 18-inch options. This post covers the 16-inch kit that the title names. It does not compare the variants or rank them.
The post does not rank this saw against other chainsaws. It is in the post because it matches the keyword and because the listing gives enough stated specifications to describe the product accurately, with the gaps shown.
The safety section draws only on university extension and Cornell Small Farms pages opened on 2026-10-22 and checked against their text.
What we could not verify
The sources we opened do not cover this model’s specifications. The listing is the only source with figures for this saw. The extension pages describe chainsaws in general, and none of them describes this model.
As a result, this post cannot confirm the 28-inch diameter claim, the runtime, the charge time, the chain speed, the oil capacity, the operation of the chain brake, or the warranty terms. It also cannot confirm that a battery of a different size is supported on the 16-inch kit.
The manufacturer’s manual and the product’s PDF documents were not opened, and PDFs are not used in this process. Their contents are therefore not covered here.
FAQ
Is the Greenworks 40V 16 inch chainsaw good for firewood?
The listing names firewood splitting among its uses and says the bar and chain handle trees and limbs up to 28 inches in diameter. Those are the stated figures. The listing gives no firewood cut count, and this post does not verify the 28-inch figure, so compare the bar length with the rounds you plan to cut.
How long does one battery last?
The listing says the 4.0Ah battery gives extended cutting time and holds charge for 12+ months. It does not give minutes or cuts per charge, so this post does not estimate a runtime.
Does the kit include a battery and charger?
Yes, for the 40V 16-inch (4.0Ah) version that the title names. The listing also shows 16-inch tool-only options, so confirm which version you are looking at before you buy.
Does this saw have a chain brake?
Yes, according to the listing’s bullet, which names a chain brake and a low-kickback design. The listing does not describe how the brake operates, so confirm that with the manufacturer’s manual before first use.
Does it run on other Greenworks batteries?
The listing says the 40V platform works with Greenworks 40V tools. It does not say that other battery sizes are supported on the 16-inch kit, and it does not say anything about batteries from other brands.
How much does the saw weigh?
The listing gives an item weight of 10.4 pounds. It does not say whether that figure includes the battery, so check the complete kit weight against how long you expect to hold the saw.
Bottom line
Buy this kit only if your work is heavy yard cutting with a 16-inch bar, you already run Greenworks 40V batteries or plan to, and you can accept that the 28-inch figure is the listing’s claim rather than a verified capacity. If you need minutes of runtime or a verified capacity, choose a saw whose listing gives those figures.
