As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
You are looking for litheli 21 cordless lawn mower alternatives because the original model may not fit your specific yard size or terrain needs. The LiTHELi 21" offers a 21-inch cutting width and 45 minutes of runtime with dual 8.0Ah batteries. Its 40V brushless motor provides reliable power, and the adjustable height settings accommodate various grass lengths. However, you might prefer a different cutting width, a self-propelled drive for slopes, or a lighter unit for tight spaces.
We selected these alternatives because their specifications overlap with the original LiTHELi 21" in key areas like voltage, motor type, or battery capacity. Each option on this list targets a specific use case, such as small yards, uneven terrain, or budget-conscious buyers. By comparing published specs like cutting width, weight, and runtime, you can find a mower that matches your exact requirements. This guide focuses strictly on technical data to help you make an informed decision without marketing noise.
Our top pick: Litheli 21-Inch 40V Cordless Lawn Mower.
How each alternative compares
woRkologie 21-Inch 2x20V Push Mower
The woRkologie 21-inch model shares the 21-inch cutting width and dual 8.0Ah battery capacity with the LiTHELi 21. It distinguishes itself with a 20V system rather than the 40V platform used by the Litheli. This mower is a push model, so you must propel it manually, similar to the base Litheli 21. It weighs 53.6 pounds, making it heavier than the LiTHELi 21 at 47.4 pounds. The brushless motor offers similar durability and efficiency. You should choose this if you prefer a 20V battery ecosystem or need a dedicated push mower with comparable runtime and cut width.
LiTHELi 21-Inch Self-Propelled Lawn Mower
This LiTHELi self-propelled model keeps the 21-inch cutting width and dual 8.0Ah batteries but shifts to a 20V system. The key difference is the self-propelled drive, which removes the need for you to push the mower. It weighs only 21.5 pounds, significantly lighter than the 47.4-pound LiTHELi 21. This makes it ideal for uneven terrain or slopes where maneuverability matters. You give up the higher 40V voltage for easier handling and self-propulsion. Select this version if you want to reduce physical effort while mowing, especially on larger or irregularly shaped lawns.
Litheli 18-Inch 40V Cordless Mower
The LiTHELi 18-inch model reduces the cutting width from 21 inches to 18 inches, which may require more passes to cover the same area. It retains the 40V brushless motor and dual 8.0Ah battery setup, offering similar runtime. This mower weighs 32.8 pounds, much lighter than the 47.4-pound LiTHELi 21. Its compact size improves maneuverability in tight spaces. You sacrifice cutting width for better handling and lower weight. Choose this alternative if you have a small yard or obstacles that make the wider 21-inch deck cumbersome.
Sun Joe 48V 15-Inch Cordless Dethatcher and Scarifier
The Sun Joe 15-inch unit is a specialized dethatcher and scarifier, not a standard lawn mower. It uses a 48V system with a 15-inch cutting width, which is narrower than the LiTHELi 21. It weighs 36.4 pounds, lighter than the LiTHELi 21. This tool is designed for lawn renovation tasks like removing thatch, not for regular mowing. You cannot use it as a direct replacement for cutting grass. Pick this option only if you need to address lawn health issues like heavy thatch buildup, rather than maintaining height and grass length.
LawnMaster 48V 19-Inch Brushless Mower
The LawnMaster 19-inch mower offers a 19-inch cutting width, narrower than the LiTHELi 21. It uses a 48V system with a brushless motor. This model weighs 37.6 pounds, lighter than the LiTHELi 21. It is designed for small yards where battery monitoring is a priority. You give up the wider 21-inch cut and the 40V platform for a different voltage ecosystem. Select this if you prefer a 48V system and a slightly lighter mower for smaller spaces, accepting the reduced cutting width.
Worx 40V 17-Inch Cordless Lawn Mower
The Worx 17-inch mower has a 17-inch cutting width, significantly narrower than the LiTHELi 21. It uses a 40V system but typically comes with a 4.0Ah battery, which offers less runtime than the dual 8.0Ah setup in the LiTHELi. It weighs 39.7 pounds, lighter than the LiTHELi 21. This model is designed for small, flat yards under a quarter acre. You sacrifice cutting width and battery capacity for a lighter, more maneuverable tool. Choose this if you have a very small lawn and prioritize ease of storage and handling over wide cuts.
