Which one should you choose?
Choose Greenworks 40V 8-Inch Cordless Pole Saw if
- You need a complete kit with a battery and charger included for immediate use.
- You prefer a lighter tool at 7.8 pounds for extended overhead work.
- You are already invested in the 40V battery platform.
Choose Greenworks 80V 10-Inch Brushless Pole Saw if
- You require more cutting power for thicker branches with an 80V system.
- You want a brushless motor for longer runtime and increased torque.
- You prefer tool-less chain tensioning for quicker maintenance adjustments.
Verdict: Choose the 40V model if you want a ready-to-use kit with a lighter weight for general pruning. Select the 80V model if you need more power for larger branches and already own compatible 80V batteries. Your decision depends on your current battery inventory and the thickness of wood you typically cut.
Power and Cutting Capacity Comparison
Voltage and Power
The Greenworks 40V 8-Inch Cordless Polesaw operates on a 40V system, while the Greenworks 80V 10" Cordless Polesaw uses an 80V platform. Higher voltage generally translates to more torque and cutting speed. The 80V model also features brushless motor technology, which provides two times more torque than standard brushed motors. This design offers longer runtime and extended motor life. You get more raw power from the 80V unit for tougher branches. The 40V model is sufficient for lighter trimming tasks but lacks the high-output capability of its higher-voltage counterpart.
Bar and Chain Length
Cutting capacity is determined by the bar length. The 40V model comes with an 8-inch bar and chain, suitable for smaller branches and general pruning. The 80V model features a larger 10-inch bar and chain. This extra two inches allows you to cut through thicker limbs in a single pass without needing to reposition the tool as often. The 10-inch bar is better for heavier pruning jobs. If you primarily deal with small twigs, the 8-inch bar is adequate. For larger branches, the 10-inch option provides a clear advantage in reach and capacity.
Chain Tensioning Mechanism
Maintenance ease varies between the two tools. The 40V polesaw requires you to manually tighten the chain for optimal performance. You need to adjust it periodically to ensure safety and efficiency. In contrast, the 80V model offers tool-less chain tensioning. This feature allows you to adjust the chain quickly and conveniently without needing additional wrenches or tools. It simplifies maintenance and keeps the chain tight during operation. For users who want faster setup and less hassle, the tool-less system is a significant practical benefit over the manual adjustment method.
Included Accessories
What you get in the box differs significantly. The 40V kit includes the polesaw, a 2.0Ah battery, and a charger, making it a complete ready-to-use package. The 80V listing is for the tool only, meaning you must purchase the battery and charger separately. If you already own compatible 80V Greenworks batteries, this is less of an issue. However, for new users, the 40V bundle provides immediate functionality. The 80V tool offers flexibility if you are building an ecosystem, but it lacks the immediate convenience of the all-in-one 40V kit.
Weight and Portability
Handling weight affects user fatigue during extended use. The 40V polesaw weighs 7.8 pounds, making it lighter and easier to maneuver overhead. The 80V tool weighs 12.7 pounds, which is nearly five pounds heavier. This additional weight comes from the more robust motor and larger frame. While the 80V provides more power, you may feel more strain holding it up for long periods. The lighter 40V model is easier to carry and operate for quick jobs. If weight is a priority, the 40V option is more comfortable for extended pruning sessions.
Choose based on power and reach needs
Users needing maximum branch cutting power
The 80V system provides higher torque and faster cutting speeds than the 40V model. Its 10-inch bar handles thicker limbs with ease. The brushless motor extends runtime and durability. You get more cutting power per charge, making it ideal for heavy pruning tasks where speed and capacity matter most.
Buyers wanting a complete ready-to-use kit
This option includes a 2.0Ah battery and charger, so you can start working immediately. The 40V platform is lighter at 7.8 pounds, reducing fatigue. It features an extendable shaft for reaching up to 11 feet. You get a full package without needing to purchase separate power sources or tools.
Those prioritizing lightweight and portability
Weighing only 7.8 pounds, this polesaw is significantly lighter than the 12.7-pound 80V alternative. The 40V battery keeps the overall weight down. This makes it easier to maneuver overhead and carry around the yard. You benefit from reduced strain during extended trimming sessions or when working on smaller branches.
