PowerSmart 40V 21" Cordless Lawn Mower Alternatives: 6 Similar Picks Compared

How these alternatives compare

Greenworks 40V 16-Inch Push Lawn Mower

The Greenworks 40V 16-Inch model cuts a narrower 16-inch path compared to the PowerSmart’s 21-inch deck. This makes it lighter at 37.5 pounds, which is easier to maneuver in tight spaces. It uses the same 40V 4.0Ah battery system, so you can share power sources if you already own Greenworks tools. The trade-off is less coverage per pass, requiring more overlap. It is best for small lawns where precision matters more than speed. You get a compact footprint but sacrifice the wide cutting width that helps clear larger areas quickly.

Greenworks 40V Cordless Push Mower Combo Kit

This Greenworks kit includes a 13-inch mower, a blower, and a trimmer, offering more versatility than the single PowerSmart unit. The mower deck is significantly narrower at 13 inches, prioritizing maneuverability in cluttered yards. It shares the 40V 4.0Ah battery platform, allowing you to use the same batteries across all three tools. The total weight is 45 pounds, which is lighter than the PowerSmart’s 56.4 pounds. This bundle is ideal if you need trimming and blowing capabilities alongside mowing. You gain tool variety but accept a much smaller cutting width that slows down large lawn coverage.

KraftSense 21-Inch 40V Cordless Push Mower

The KraftSense 21-Inch model matches the PowerSmart’s 21-inch cutting width, providing similar coverage per pass. It also uses a 40V 4.0Ah battery system for compatible power sources. However, the data does not list a weight for this unit, so you cannot compare maneuverability directly. It is positioned as a solid choice for flat yards where push effort is manageable. The primary difference is the brand ecosystem and specific deck construction details not fully detailed here. It serves as a direct alternative for those who want the same width but prefer a different brand or aesthetic finish.

PowerSmart 40V 17-Inch Cordless Push Lawn Mower

This PowerSmart 17-Inch model features a narrower 17-inch deck compared to the 21-inch original. It includes a 3-in-1 function for mulching, bagging, and side discharge, matching the versatility of the main pick. It uses the same 40V 4.0Ah battery and brushless motor technology. The unit weighs less, making it easier to handle in medium-sized yards. You trade a wider cutting path for better maneuverability in tighter spaces. This model is suitable if you prioritize clipping management options over maximum coverage width. It keeps the brand’s steel deck durability while offering a more compact footprint.

Westinghouse 40V 18in Brushless Mower

The Westinghouse 40V 18-Inch mower offers a middle ground with an 18-inch cutting width, narrower than the PowerSmart’s 21 inches. It features a brushless motor for efficient power delivery. The unit weighs 36 pounds, significantly lighter than the PowerSmart’s 56.4 pounds, which aids in push effort. It includes two 4.0Ah batteries, similar to the dual-battery setup of the original. This model is best for small yards where edge-to-edge cutting precision is valued. You gain a lighter, more manageable machine but lose the wider deck that reduces the number of passes needed for larger areas.

Litheli 40V 16-Inch Brushless Push Mower

The Litheli 40V 16-Inch model has a narrower 16-inch deck, making it suitable for smaller, more confined lawns. It weighs 35.7 pounds, which is much lighter than the PowerSmart’s 56.4 pounds. This reduces fatigue during mowing sessions. It uses a brushless motor and includes two 4.0Ah batteries for extended runtime. The trade-off is a smaller cutting width that requires more passes to cover the same area. It is ideal for users who prioritize portability and lightweight handling over wide coverage. You get a compact, easy-to-store unit that fits well in smaller garages or sheds.
