6 Best Alternatives to the Greenworks 48V 21" Self-Propelled Mower (2026)

How each alternative compares

Sun Joe 48V 15-Inch Cordless Dethatcher and Scarifier

The Sun Joe 48V 15-Inch Cordless Dethatcher is a specialized tool, not a direct mower replacement. It features a 15-inch cutting width and a brushless motor. You get a lighter unit at 36.4 pounds compared to the Greenworks 43-pound mower. This model lacks self-propulsion, requiring manual pushing. It targets users who need lawn renovation rather than standard grass cutting. The 15-inch width is narrower than the Greenworks 21-inch deck. You trade mowing versatility for focused thatch removal. This choice suits small yards needing scarification. It does not offer the 3-in-1 mulching or bagging options found in the original Greenworks mower. You must manage two different tool systems for yard care.

Greenworks 48V 15-Inch Cordless Dethatcher and Scarifier

The Greenworks 48V 15-Inch Cordless Dethatcher focuses on lawn aeration and thatch removal. It uses a 4.0 Ah battery, whereas the original Greenworks mower includes two 5.0 Ah batteries. This unit weighs only 26 pounds, making it significantly lighter than the 43-pound mower. It has a 15-inch working width, which is narrower than the 21-inch deck of the original. You get a dedicated tool for turf health instead of a multi-function mowing system. It lacks the self-propelled drive and LED lights of the original. The runtime varies based on grass conditions. This alternative is best for homeowners who already have a mower and need supplemental dethatching. It does not replace the primary mowing function of the Greenworks 48V 21-inch model.

NovorikX 21-Inch 60V Self-Propelled Cordless Mower

The NovorikX 21-Inch 60V Self-Propelled Mower offers higher voltage and raw power. It uses a 60V system with a 5.0 Ah battery, compared to the Greenworks 48V setup. The NovorikX weighs 65.9 pounds, which is 22.9 pounds heavier than the Greenworks mower. It features a brushless motor and self-propelled drive. You get a 21-inch cutting width, matching the original. This model suits dense lawns and variable terrain where extra torque is needed. It lacks the included trimmer and blower attachments of the Greenworks combo. The heavier weight may affect portability and storage. You trade the multi-tool versatility for dedicated mowing performance. This choice fits users who prioritize cutting power over the convenience of an all-in-one yard system.

PowerSmart 21-Inch 125cc Push Lawn Mower

The PowerSmart 21-Inch 125cc Push Lawn Mower uses a gas engine, not a battery. It weighs 28.1 pounds, which is 14.9 pounds lighter than the Greenworks mower. This model offers mechanical simplicity and mulching versatility. It lacks the self-propelled drive of the original Greenworks unit. You must push it manually across the lawn. The 125cc engine provides consistent power without runtime concerns. It is ideal for flat lawns where manual pushing is manageable. You trade cordless convenience and LED lights for engine reliability. This alternative suits users who prefer gas power over battery management. It does not include the trimmer or blower attachments. You get a dedicated mowing tool with side discharge or mulching capabilities. It is a simpler, lighter option for basic lawn care.

KraftSense 18-Inch 20V Self-Propelled Lawn Mower

The KraftSense 18-Inch 20V Self-Propelled Lawn Mower is designed for small yards. It has an 18-inch cutting width, which is narrower than the Greenworks 21-inch deck. It weighs 29.3 pounds, making it 13.7 pounds lighter than the original. This model features a brushless motor and self-propelled drive. You get a foldable design for compact storage. The 20V system offers less power than the 48V Greenworks setup. It lacks the included trimmer and blower attachments. This choice suits users who need a lightweight, mulching-focused mower. You trade cutting width and runtime for portability. It is ideal for small lawns where a full-size mower is unnecessary. You get reliable brushless performance without the weight of a larger system.

LiTHELi 21-Inch Self-Propelled Lawn Mower

The LiTHELi 21-Inch Self-Propelled Lawn Mower features an 8.0 Ah battery, offering extended runtime. It weighs only 21.5 pounds, which is 21.5 pounds lighter than the Greenworks mower. This model has a 21-inch cutting width, matching the original. It uses a brushless motor and self-propelled drive. The lightweight design helps tackle uneven lawns without stalling. You get a dedicated mowing tool without the included trimmer or blower. The 20V system provides less voltage than the 48V Greenworks. This choice suits users who prioritize runtime and ease of handling. You trade the multi-tool versatility for a focused, lightweight mowing experience. It is ideal for homeowners who need a manageable, self-propelled mower for irregular terrain. You get robust runtime without the bulk of a heavier system.
