6 Best Alternatives to the LiTHELi 21-Inch Self-Propelled Cordless Mower (2026)

How alternatives compare to LiTHELi

Litheli 21-Inch 40V Mower with 8.0Ah Battery

This LiTHELi model keeps the 40V brushless motor but swaps the self-propelled drive for a push design. It offers a wider 21-inch cutting deck compared to the original's standard width. The battery capacity remains at 8.0 Ah, matching the runtime potential of the self-propelled version. You gain a slightly broader cut path but lose the variable speed drive that handles slopes and uneven terrain. This option suits users who prefer manual control or have flat, small-to-medium lawns. It is ideal if you want a lighter, simpler machine without the mechanical complexity of a drive system. The trade-off is physical effort for a potentially faster mowing pace on level ground.

PowerSmart 20-Inch Self-Propelled Cordless Mower

The PowerSmart 20-Inch model reduces the cutting width from 21 inches to 20 inches. It maintains the self-propelled drive and 40V brushless motor found in the original. However, it uses two 4.0 Ah batteries instead of a single high-capacity pack. This configuration provides similar total capacity but may require swapping batteries sooner if you run out. The self-propelled system helps with terrain, similar to the LiTHELi. This mower is best for small lawns under a quarter acre where the narrower deck improves maneuverability. It offers a practical balance of power and size for tighter spaces. You sacrifice a bit of cutting width for better handling in confined areas.

Neobitat 18" 40V Cordless Push Mower

The Neobitat 18-Inch mower drops the self-propelled feature entirely, reverting to a push design. It keeps the 40V brushless motor but uses an 18-inch cutting deck, which is narrower than the original. The battery capacity is 8.0 Ah, matching the original's runtime potential. This model is designed for small lawns where manual pushing is manageable. You lose the convenience of self-propulsion and the wider cut width. It is a budget-friendly choice for users with flat, small yards. The narrower deck makes it easier to store and maneuver around obstacles. This option fits those who prioritize cost and simplicity over power and ease of use on larger or sloped lawns.

Greenworks 40V 25-Inch Self-Propelled Mower

The Greenworks 25-Inch model significantly increases the cutting width from 21 to 25 inches. It retains the self-propelled drive and 40V brushless motor. However, it uses two 4.0 Ah batteries, which may offer less total runtime than the original's high-capacity setup. The wider deck covers more ground per pass, reducing mowing time on large lawns. You gain efficiency but lose some maneuverability in tight spaces. This mower is ideal for large yards where speed is a priority. The self-propelled system handles the increased width and weight. It is a practical choice for users who want to finish mowing faster and have the space to accommodate the wider deck.

KraftSense 18-Inch 40V Self-Propelled Mower

The KraftSense 18-Inch mower reduces the cutting width to 18 inches and keeps the self-propelled drive. It uses a 40V brushless motor, similar to the original. The model is designed for small lawns under an eighth of an acre. You lose the wider cutting path but gain a lighter, more compact machine. The self-propelled system aids in navigating small, potentially uneven yards. This option is best for users with very small residential lawns who need a narrow deck for precision. It offers reliable performance in tight spaces. The trade-off is a smaller cut width, which may require more passes. It is a practical choice for minimal lawn maintenance needs.

Greenworks 40V 21" Self-Propelled Lawn Mower

The Greenworks 21-Inch model matches the original's cutting width and self-propelled drive. It uses a 40V brushless motor but includes a 5.0 Ah battery, which is smaller than the original's 8.0 Ah option. This may result in reduced runtime per charge. The steel deck offers durability compared to the original's construction. It is suitable for standard yards where a 21-inch cut and reliable traction are key. You trade battery capacity for a potentially more durable deck. This mower is ideal for users who prioritize deck longevity and consistent self-propelled performance. It fits those who do not need maximum runtime and prefer a traditional, robust build.
