The PowerSmart 20-Inch Self-Propelled Cordless Mower offers a reliable baseline with its 40V brushless motor and dual 4.0Ah batteries. You get a 20-inch cutting width and self-propelled rear-wheel drive for manageable hills. However, you might seek powersmart 20 inch self propelled cordless mower alternatives if you need a wider deck, higher voltage, or a different drive style. Some users prefer the extra reach of a 21-inch or 25-inch cut, while others want a lighter push model for small, flat yards.
We selected these 6 options because their core specifications overlap with the PowerSmart model. This list includes other 40V and 60V cordless mowers with brushless motors and self-propelled drives. You will find variations in cutting width, battery capacity, and lawn size coverage. For example, the Greenworks 60V option provides higher voltage for medium to large yards, while the Greenworks 40V 25-Inch model offers a wider cut for efficiency. These alternatives let you compare practical specs like deck size and power type to find the best fit for your specific lawn conditions.
How each alternative compares
Greenworks 40V 25-Inch Self-Propelled Mower
The Greenworks 40V 25-Inch Self-Propelled Mower offers a wider 25-inch cutting deck compared to the PowerSmart’s 20-inch width. This five-inch increase reduces the number of passes needed for medium to large lawns. Both models share the same 40V brushless motor and self-propelled drive type. The Greenworks unit weighs 76.2 pounds, which is significantly heavier than the PowerSmart’s 57.5 pounds. You gain coverage area but lose some maneuverability in tight spaces. This option suits users who prioritize faster mowing times over a lighter, more compact machine. It is a practical choice for those with wider yards who want to reduce overall mowing duration.
RYOBI 40V HP Brushless 20-Inch Self-Propelled Mower
The RYOBI 40V HP Brushless 20-Inch Self-Propelled Mower matches the PowerSmart in cutting width and voltage. Both feature 20-inch decks and brushless motors for efficient operation. The RYOBI model focuses on a balanced mix of power and maneuverability within a compact frame. While the PowerSmart includes dual 4.0Ah batteries in its standard kit, the RYOBI data highlights its balanced performance profile for standard lawns. You get similar cutting capabilities but may find the RYOBI’s handling slightly different due to its specific design. This mower is ideal for homeowners who want a reliable 20-inch self-propelled option without needing the extra runtime of dual batteries. It serves as a direct competitor for those who value balanced power delivery.
Greenworks 60V 21" Brushless Self-Propelled
The Greenworks 60V 21-Inch Brushless Self-Propelled Mower steps up to a 60V system, providing higher voltage than the PowerSmart’s 40V motor. It also features a 21-inch cutting width, which is one inch wider than the PowerSmart’s 20-inch deck. Both models support self-propelled drive and include dual 4.0Ah batteries for extended runtime. The higher voltage system is designed for medium to large yards up to 3/4 acre. You gain extra cutting reach and potential power for thicker grass. This alternative is best for users who need to cover larger areas or tackle tougher vegetation. It offers a noticeable upgrade in system voltage and deck size while maintaining the convenience of dual-battery operation.
WORX 40V 14-Inch Cordless Dethatcher and Scarifier
The WORX 40V 14-Inch Cordless Dethatcher and Scarifier is a specialized tool rather than a standard mower. It features a narrow 14-inch cutting width, which is much smaller than the PowerSmart’s 20-inch deck. This device is designed for dethatching and scarifying small lawns using existing 40V batteries. It weighs only 26.2 pounds, making it significantly lighter than the 57.5-pound PowerSmart mower. You use this for targeted lawn health maintenance instead of general grass cutting. It is ideal for homeowners who need to aerate their lawn without replacing their entire mowing setup. This option serves users who prioritize lawn health tools over primary mowing capabilities, fitting a very specific niche of small lawn care.
Skil PWR CORE 40 20-Inch Self-Propelled Mower
The Skil PWR CORE 40 20-Inch Self-Propelled Mower matches the PowerSmart with a 20-inch cutting width and self-propelled drive. Both use 40V brushless motors for efficient performance. The Skil model is highlighted for its variable speed control and runtime capabilities. It is a solid choice for users who want precise control over their mowing speed. While the PowerSmart emphasizes dual-battery runtime, the Skil focuses on versatile operation with variable speed features. You get a comparable cutting width but with different operational controls. This mower suits those who prioritize adjustable self-propulsion speed and runtime efficiency. It is a practical alternative for users who want a standard 20-inch self-propelled mower with added speed flexibility.
Greenworks 40V 20-Inch Push Lawn Mower
The Greenworks 40V 20-Inch Push Lawn Mower shares the same 20-inch cutting width and 40V brushless motor as the PowerSmart. The key difference is the drive type. The Greenworks is a push mower, whereas the PowerSmart is self-propelled. You must provide the forward momentum yourself with the Greenworks model. This makes it lighter and more compact for storage. The Greenworks weighs 57.5 pounds, similar to the PowerSmart, but lacks the rear-wheel drive assistance. This option is best for small, flat lawns under 1/3 acre where self-propulsion is not necessary. You gain easier manual control and storage convenience but lose the effort-saving benefit of self-propulsion on hills or larger areas.
