Greenworks 40V 21" Brushless Cordless Alternatives: 6 Similar Picks Compared

How each alternative compares

LiTHELi 18" 40V Self-Propelled Mower

The LiTHELi 18-inch model uses a 40V brushless motor and 5.0Ah battery like the Greenworks original, but it reduces the cutting width to 18 inches. This narrower deck makes the unit lighter and easier to maneuver in tight spaces or small yards. It retains the self-propelled drive for easier handling on slopes. You trade some cutting efficiency per pass for better control in confined areas. This option suits users who prioritize manageable size over maximum coverage width. The 18-inch deck is ideal for smaller lawns where the 21-inch width feels bulky. You get similar runtime and power in a more compact package.

Greenworks 80V 25-Inch Self-Propelled Lawn Mower

The Greenworks 80V 25-inch mower steps up significantly in both voltage and cutting width compared to the 40V 21-inch original. It doubles the voltage to 80V, providing higher torque for thicker grass, while expanding the deck to 25 inches. This wider cut covers more ground per pass, reducing total mowing time. It remains self-propelled with rear-wheel drive for consistent traction. The 5.0Ah battery is included, though the higher voltage system may drain it faster under heavy loads. This model is best for larger lawns where speed and power matter more than compact storage. You gain efficiency and cutting power, accepting a heavier, larger machine in return.

Greenworks 40V Cordless Push Mower Combo Kit

This Greenworks 40V push mower combo kit drops the self-propelled feature found in the original, offering a manual push design instead. It features a narrower 13-inch cutting width, which is less efficient for large areas but easier to store and handle in tight spaces. The kit includes a 4.0Ah battery, slightly lower capacity than the original’s 5.0Ah, and bundles additional tools like a trimmer and blower. This makes it a practical choice if you need edge trimming and debris blowing capabilities. You sacrifice self-propelled convenience and cutting width for versatility and a complete tool set. It is ideal for small yards where you want multiple tools in one ecosystem without the bulk of a self-propelled mower.

Litheli 40V 16-Inch Brushless Push Mower

The Litheli 16-inch push mower offers a 40V brushless motor and 5.0Ah battery similar to the original, but it lacks self-propelled drive. Its 16-inch cutting width is narrower, making it best for small lawns and tight storage spaces. The push design requires more physical effort on slopes or thick grass compared to the original’s rear-wheel drive. It focuses on lightweight handling and mulching capabilities. You give up the ease of self-propulsion and the wider 21-inch deck for a more compact, affordable option. This model suits users with small yards who prioritize maneuverability and storage size over cutting speed and reduced physical exertion.

Litheli 21-Inch 40V Mower with 8.0Ah Battery

The Litheli 21-inch mower matches the original’s cutting width but upgrades the battery capacity to 8.0Ah, offering significantly longer runtime. It uses a 40V brushless motor, providing comparable power to the Greenworks original. However, it is a push mower, lacking the self-propelled feature that reduces physical effort on uneven terrain. This model prioritizes extended battery life over convenience features. You gain up to 60% more runtime potential, which is beneficial for larger lawns, but you must push the unit manually. It is a solid choice for users who need longer mowing sessions and do not mind the extra effort of a push design.

Litheli 40V 16-Inch Brushless Cordless Mower

The Litheli 16-inch brushless mower shares the 40V voltage and 5.0Ah battery capacity of the original but features a narrower 16-inch deck. It is a push mower, so it lacks the self-propelled drive of the Greenworks 21-inch model. This narrower width makes it easier to store and maneuver in tight spaces, such as between garden beds. It focuses on mulching functionality and quiet operation. You trade the wider 21-inch cutting path and self-propelled convenience for a more compact, manageable unit. This option is best for small lawns under a quarter acre where storage space is limited and maximum cutting width is not a priority.
