How each alternative compares
LiTHELi 21-Inch Self-Propelled Lawn Mower
The LiTHELi 21-Inch Self-Propelled Mower swaps gas for 40V cordless power. It uses a brushless motor and an 8.0 Ah battery for extended runtime. Unlike the PowerSmart push model, this mower drives itself, reducing physical effort on larger lawns. You gain quiet operation and zero emissions, but you lose the instant refueling convenience of gas. The weight drops to 21.5 pounds, making it lighter than the PowerSmart’s 62-pound frame. Choose this if you prefer electric convenience and self-propelled ease over manual pushing and engine maintenance.
BILT HARD 20-Inch 144cc Gas Push Mower
The BILT HARD 20-Inch Gas Push Mower offers a steel deck and a 144cc engine, providing more torque than the PowerSmart’s 125cc unit. It focuses on side discharge rather than mulching, simplifying the mowing function. The cutting width is slightly narrower at 20 inches compared to the PowerSmart’s 21-inch deck. Both are push mowers, so you must provide the propulsion. This model suits users who want robust gas power with a simpler discharge-only setup. It is a practical choice if you prefer steel durability and do not need mulching capabilities or self-propulsion.
KraftSense 18-Inch 20V Self-Propelled Lawn Mower
The KraftSense 18-Inch 20V Self-Propelled Mower targets small yards with its compact 18-inch deck. It is cordless and self-propelled, offering easier maneuverability in tight spaces compared to the larger PowerSmart. The brushless motor provides efficient power, but the narrower cut means more passes are needed. Its self-propelled drive removes the need for manual pushing, a significant upgrade over the PowerSmart’s push-only design. Storage is easier due to the smaller footprint. Pick this mower if you have a small lawn and value compact storage and electric simplicity over wide cutting paths.
Etoolab 40V 17" Cordless Mower
The Etoolab 40V 17-Inch Cordless Mower is designed for small yards and patio areas. Its 17-inch cutting width is significantly narrower than the PowerSmart’s 21-inch deck, making it ideal for tight spaces. It is fully cordless, eliminating gas fumes and maintenance. The lightweight design aids in easy handling, though it lacks self-propulsion. You trade cutting width for maneuverability in confined areas. This mower is best for users with very small lawns who prioritize electric convenience and easy storage over the broader coverage and gas power of the PowerSmart model.
Sun Joe 48V 15-Inch Cordless Dethatcher and Scarifier
The Sun Joe 48V 15-Inch Cordless Dethatcher is not a mower but a scarifier for lawn rejuvenation. It features a 15-inch width and uses a brushless motor for dethatching tasks. Unlike the PowerSmart, which cuts grass, this tool removes thatch and scarifies the soil. It is a specialized accessory for lawn care rather than a replacement for mowing. Choose this if you need to maintain lawn health between mowing sessions. It complements your existing mower rather than replacing it, offering precise depth adjustments for dethatching without the need for gas or heavy pushing.
Litheli 14-Inch Brushless Cordless Lawn Mower
The Litheli 14-Inch Brushless Cordless Lawn Mower is the smallest option, with a 14-inch deck for tight spaces. It is a push mower, similar to the PowerSmart, but uses 40V cordless power. The brushless motor ensures efficiency, and the bagging function keeps clippings contained. It is much lighter and narrower than the PowerSmart, making it easy to store and maneuver. You give up cutting width and gas power for compact electric convenience. This model is ideal for small yards where storage space is limited and quiet, clean operation is a priority over raw power.
