NBKXDEL 21 Inch Cordless Lawn Mower Alternatives: 6 Similar Picks Compared

How these alternatives differ from the NBKXDEL

Litheli 21-Inch 40V Mower with 8.0Ah Battery

The Litheli 21-Inch 40V Mower shares the same 40V voltage and 8.0 Ah battery capacity as the NBKXDEL, but it is a brushless model designed for small to medium lawns. While the NBKXDEL emphasizes durability and DeWalt 20V compatibility, the Litheli focuses on runtime and included accessories. You get a similar 21-inch cutting width, but the Litheli lacks the specific mention of a multi-position height lever found in the NBKXDEL data. This pick suits users who prioritize runtime and accessory inclusion over the specific battery ecosystem compatibility of the NBKXDEL. It is a solid push mower alternative if you do not need the 8-position adjustment range.

woRkologie 21-Inch 2x20V Push Mower

The woRkologie 21-Inch 2x20V Push Mower uses a 20V system instead of the NBKXDEL’s 40V setup, though it also includes two 8.0 Ah batteries. It is a brushless push mower aimed at users with existing DeWalt 20V battery systems. The woRkologie sacrifices the higher voltage runtime of the NBKXDEL for compatibility and compact storage. You get a similar 21-inch cutting width and brushless motor, but the lower voltage may reduce power on thick grass. This mower is best for those who already own DeWalt 20V tools and need a compact solution for small yards, rather than users seeking the extended runtime of the 40V NBKXDEL.

Neobitat 18" 40V Cordless Push Mower

The Neobitat 18-Inch 40V Cordless Push Mower offers a narrower 18-inch cutting width compared to the NBKXDEL’s 21-inch deck. It is a brushless model designed for small lawns where mulching is key. The Neobitat fits buyers who value compact storage and precise height adjustments over a wide cutting swath. You get the same 40V voltage and 8.0 Ah battery capacity, but the smaller deck means more passes are needed. This pick is ideal for small yards where maneuverability and storage convenience are priorities. It gives up the wide coverage of the NBKXDEL for a more manageable footprint in tight spaces.

Litheli 18-Inch 40V Brushless Mower

The Litheli 18-Inch 40V Brushless Mower is a compact, lightweight option for small yards. It shares the 40V voltage and 8.0 Ah battery capacity with the NBKXDEL but features a smaller 18-inch cutting width. This model suits users who value easy storage and quiet performance over wide cutting swathes. You get a brushless motor and cordless power, but the reduced deck size means more mowing passes. The Litheli is lighter and more maneuverable than the NBKXDEL. It is the better choice if you have a small lawn and prioritize storage convenience and ease of handling over the wider coverage provided by the NBKXDEL.

LiTHELi 21-Inch Self-Propelled Cordless Mower

The Litheli 21-Inch Self-Propelled Cordless Mower adds self-propulsion to the 21-inch cutting width, unlike the push-only NBKXDEL. It uses a 40V system with an 8.0 Ah battery but features a unique 4-battery configuration. This model offers variable speed control and electric height adjustment, which the NBKXDEL lacks. You get the same cutting width and brushless motor, but the self-propelled drive helps on slopes. The trade-off is the complex battery setup. This pick is best for users who value drive assistance and electric adjustments over the simpler push design and DeWalt compatibility of the NBKXDEL.

Greenworks 40V 14-Inch Brushless Push Mower

The Greenworks 40V 14-Inch Brushless Push Mower offers a significantly narrower 14-inch cutting width compared to the NBKXDEL’s 21-inch deck. It uses a 40V system but with a smaller 4.0 Ah battery, reducing runtime. This compact model is designed for small lawns and tight spaces. You get a brushless motor and cordless power, but the smaller battery and deck mean more frequent charging and more passes. The Greenworks suits users who prioritize maneuverability and existing tool compatibility over wide cutting paths. It is the best alternative for very small yards where the NBKXDEL’s larger size would be cumbersome.
