6 Best Alternatives to the NBKXDEL 21 Inch Electric Lawn Mower (2026)

How these alternatives compare

woRkologie 21-Inch Brushless Mower and Trimmer Combo

The woRkologie 21-Inch Brushless Mower and Trimmer Combo offers a similar dual-tool setup to the NBKXDEL, but with a different weight profile. It weighs 61.4 pounds, which is heavier than the NBKXDEL’s base unit. Both use 20V brushless motors and include 8.0Ah batteries for the mower. The woRkologie model focuses on budget-friendly dual maintenance. You get a 12-inch trimmer and 21-inch mower. However, it lacks the specific 8-position height adjustment detail found in the NBKXDEL specs. If you want a combined tool set without self-propulsion, this is a direct alternative. It suits small to medium yards where manual pushing is acceptable. The shared battery platform remains a key convenience factor for both.

woRkologie 21-Inch 2x20V Push Mower

The woRkologie 21-Inch 2x20V Push Mower drops the trimmer entirely to focus on mowing efficiency. It weighs 53.6 pounds, which is lighter than the woRkologie combo but heavier than some competitors. It uses two 8.0Ah batteries for extended runtime, matching the NBKXDEL’s capacity but without the trimmer batteries. This model is strictly a push mower, so you must provide the forward momentum. It lacks self-propulsion, similar to the NBKXDEL. The brushless motor ensures durability and lower noise. If you already own a trimmer or do not need one, this mower offers a streamlined approach. It is ideal for flat lawns where you do not need the versatility of a string trimmer attachment. The 21-inch cutting width matches the original.

Litheli 21-Inch Self-Propelled 40V Lawn Mower

The Litheli 21-Inch Self-Propelled 40V Lawn Mower steps up to a 40V system, providing more power than the NBKXDEL’s 20V setup. It features self-propelled drive, which eliminates the manual pushing required by the NBKXDEL. This makes it better for uneven lawns and slopes. It includes dual 8.0Ah batteries for comparable runtime. The cutting width is 21 inches, matching the original. However, it does not include a trimmer, so you lose the combo convenience. The self-propelled mechanism adds weight and complexity but reduces physical effort. If you have a larger or sloped yard, this upgrade in voltage and drive type is worth the trade-off. It suits users who prioritize ease of movement over the compactness of a push mower.

BLACK+DECKER 20-Inch Corded Push Mower

The BLACK+DECKER 20-Inch Corded Push Mower replaces battery runtime with unlimited power via a cord. It has a 20-inch cutting width, which is slightly narrower than the NBKXDEL’s 21-inch deck. It is a push mower, requiring manual effort similar to the NBKXDEL. The key difference is the power source; you must manage a cord, which limits range but ensures constant power. It lacks a trimmer attachment. This model suits users with large lawns where battery swaps are inconvenient. It offers endless runtime for extensive areas. The 20-inch width may require more passes than the 21-inch NBKXDEL. It is a solid choice for those who prioritize consistent power over cordless convenience and do not need edging capabilities.

LiTHELi 21-Inch Self-Propelled Lawn Mower

The Litheli 21-Inch Self-Propelled Lawn Mower uses a 20V system, matching the NBKXDEL’s voltage but adding self-propelled drive. It weighs only 21.5 pounds, which is significantly lighter than the NBKXDEL’s total package. It includes a brushless motor and 8.0Ah battery. The self-propelled feature reduces physical strain, unlike the push-only NBKXDEL. It does not include a trimmer, focusing solely on mowing. The 21-inch cutting width is identical. This model is ideal for users who want the convenience of self-propulsion without upgrading to 40V. It suits medium-sized yards where maneuverability is key. The lower weight makes it easier to store and handle. If you find the NBKXDEL too heavy to push, this lighter self-propelled option is a practical alternative.

Litheli 21-Inch 40V Cordless Lawn Mower

The Litheli 21-Inch 40V Cordless Lawn Mower offers quiet operation and compact storage compared to the NBKXDEL. It uses a 40V system for increased power but lacks self-propulsion. It weighs 47.4 pounds, which is lighter than the NBKXDEL combo. The 21-inch cutting width matches the original. It does not include a trimmer, so you lose the dual-tool benefit. The compact design aids in storage, which is useful for small sheds. It is best for flat lawns where quiet operation is valued. The 40V battery provides robust performance. If you need a powerful, quiet mower and do not require a trimmer, this is a strong choice. It sacrifices the combo convenience for a dedicated, quieter mowing experience.
