Greenworks 40V 18ft Brushless Cordless Chainsaw - Strong, Quiet

In this review the Greenworks 40V 18' Brushless Cordless Chainsaw is presented as a practical cordless alternative for homeowners and light contractors who need reliable cutting without gas maintenance. The single biggest reason to buy is the combination of a brushless motor and an 18' chain and bar that delivers impressive cutting power and quieter operation than comparable gas saws, while avoiding fumes and routine engine service. It works well for tree felling, limbing, pruning, and producing firewood on small to medium jobs.

Key Features

• 18' chain and bar: Provides the reach and cutting capacity to fell small trees and handle limb work with efficient slices through 4x4 lumber.
• Brushless motor technology: Delivers roughly twice the torque of brushed motors for stronger cutting, longer runtimes, and extended motor life.
• Automatic oiler: Keeps the chain lubricated during use to reduce wear and maintain consistent cutting performance without constant attention.
• Easy adjust tensioning: Makes bar and chain maintenance straightforward so users can tighten or loosen the chain quickly in the field.
• Push button start: Simplifies operation with no gas, no carburetor, no spark plug, and no starter rope for cleaner, fuss-free starting.
• 40V platform compatibility: Works with the Greenworks 40V battery line so users can swap batteries across 40+ tools if they already own other equipment.

Who It's For

The chainsaw is ideal for homeowners, gardeners, and part-time landscapers who need a capable, low-maintenance saw for trimming, pruning, limbing, and cutting firewood. Its weight and quiet operation make it especially suitable for users who prefer an easier-to-handle tool compared with heavier gas models.

It is less suitable for full-time professional arborists who demand continuous heavy-duty use on large timber; those users should look for professional gas or industrial cordless systems designed for sustained high-volume cutting and rapid battery swaps.

Pros & Cons

Pros

• Strong cutting power for its class thanks to the brushless motor and 18' bar.
• Quiet operation and no gas means cleaner starts and less noise for neighborhood use.
• Automatic oiler and easy tensioning reduce routine maintenance time.
• Platform battery compatibility offers flexibility across other 40V tools.

Cons

• Battery and charger are sold separately, so total cost can be higher if you do not already own a 40V battery.
• Not intended for continuous professional heavy-duty cutting on large trees.

Frequently Asked Questions

Does this saw come with a battery?
The product is tool only; batteries and chargers are sold separately so buyers should budget for a compatible 40V battery if they do not already own one.

How much cutting can I expect from a single charge?
Runtime depends on battery capacity, but the 18' bar and brushless motor can achieve long runs; example claims note up to around 250 cuts on 4x4 lumber on a single charge with higher-capacity batteries.

Is it suitable for felling trees?
Yes for small to medium trees and routine yard felling, limbing, pruning, and firewood; it is not intended to replace heavy professional gas saws for continuous, large-tree work.
