Comparing similar cordless mower picks
Greenworks 80V 25-Inch Cordless Self-Propelled Mower
This model offers a wider 25-inch cutting deck compared to the original's 21-inch width, allowing you to cover large lawns faster. It shares the 80V voltage and brushless motor technology but includes a blower accessory, adding versatility for yard cleanup. The steel deck construction matches the original's durability. However, the total weight reaches 98 pounds, making it significantly heavier to maneuver than the 64.2-pound original. You gain cutting width and tool compatibility but sacrifice some lightweight agility. This pick suits users with expansive yards who value a broader cut and accessory inclusion over a lighter frame.
Greenworks 60V 21" Brushless Self-Propelled
This mower drops the voltage to 60V, which may reduce peak torque compared to the original's 80V system. It retains the 21-inch cutting width and self-propelled drive, ensuring similar maneuverability. The brushless motor provides efficient power delivery, though runtime specifics vary by battery configuration. It is designed for users already invested in the 60V Greenworks ecosystem, offering battery compatibility across multiple tools. You trade raw voltage power for potential cost savings if you own other 60V devices. This option is best for those who prioritize ecosystem integration over maximum voltage output and torque performance.
PowerSmart 20-Inch Self-Propelled Cordless Mower
This mower uses a 40V dual-battery system, providing extended runtime potential compared to the single 4.0Ah battery in the original. The 20-inch cutting deck is slightly narrower, which may require more passes on larger lawns. It features a brushless motor and self-propelled drive, similar to the original, but weighs less at 57.5 pounds. The lower voltage system offers quieter operation, appealing to those sensitive to noise. You gain flexibility with dual batteries and reduced weight but lose the higher torque and wider cut of the 80V model. This pick fits users with small yards who value quiet performance and runtime extension.
Greenworks 40V 25-Inch Self-Propelled Mower
This model features a 25-inch cutting deck, offering a wider swath than the original's 21-inch width for faster mowing on large areas. It operates on a 40V system, which is lower voltage than the original's 80V, potentially affecting peak power. The dual-blade design and brushless motor aim for consistent cuts. It includes automatic battery management for efficient power distribution. The weight is 76.2 pounds, heavier than the original, which may impact maneuverability. This option suits users with existing 40V Greenworks tools who need a wider cut and do not require the highest voltage output for their lawn size.
KraftSense 18-Inch 80V Self-Propelled Mower
This mower has an 18-inch cutting deck, significantly narrower than the original's 21-inch width, making it less suitable for large lawns. It shares the 80V voltage and brushless motor, providing similar torque characteristics. The self-propelled drive aids in maneuverability. At 26.4 pounds, it is much lighter than the original, enhancing ease of use and storage. The compact design fits small lawns under a quarter acre. You gain a lightweight, compact machine with high voltage power but sacrifice cutting width and coverage speed. This pick is ideal for users with small properties who prioritize portability and ease of handling over wide-area efficiency.
SUNTEK 40V 21" Brushless Self-Propelled
This model operates on a 40V system, lower than the original's 80V, which may result in less peak torque. It features a 21-inch cutting deck, matching the original's width. The brushless motor and self-propelled drive provide comparable maneuverability. It supports dual-battery runtime, offering extended operation time compared to the single battery setup. The weight is 69 pounds, slightly heavier than the original. Smart charging features and app connectivity are highlighted, adding convenience for battery management. You gain runtime flexibility and smart features but trade raw voltage power. This option suits users who value extended runtime and smart technology over maximum voltage output.
