MZK 40V 16" Electric Lawn Mower, 2-in-1 Brushless vs PowerSmart Self Propelled Gas Lawn Mower 21-inch
Updated July 2026 — full head-to-head comparison.
Price Comparison
The MZK 40V 16" Electric Lawn Mower is priced at $259.99, while the PowerSmart Self Propelled Gas Lawn Mower costs $339.99. This makes the MZK mower about 24% cheaper than its competitor. For those on a budget or looking for a cost-effective solution for lawn maintenance, the MZK presents a compelling option. However, the price difference may reflect the additional features and capabilities of the PowerSmart mower, which could justify the higher investment for some users.
Power Source
The MZK mower utilizes a high-performance brushless motor powered by two 40V 4.0Ah lithium batteries, providing up to 45 minutes of runtime on a full charge. In contrast, the PowerSmart mower is equipped with a 170cc OHV 4-cycle gas engine, designed for improved cutting efficiency and easy starting. This fundamental difference in power source affects performance, with the MZK being suitable for smaller to medium lawns and the PowerSmart potentially handling more challenging terrains due to its gas-powered capability.
Cutting Width and Efficiency
The MZK mower has a cutting width of 16 inches, while the PowerSmart features a larger 21-inch steel deck. The wider cutting width of the PowerSmart allows it to cover more ground in a single pass, making it more efficient for larger lawns. Additionally, the PowerSmart mower's superior mulching blade contributes to faster mowing times. Users with expansive lawns may find the PowerSmart's broader cutting ability significantly beneficial.
Mowing Versatility
The MZK mower supports 2-in-1 mowing options with mulching and rear bagging, while the PowerSmart mower offers 3-in-1 versatility, including mulching, side discharge, and rear bagging. The PowerSmart’s additional functionality may appeal to users looking for more options in lawn care. However, both mowers include features that allow for grass collection, ensuring that users can maintain a tidy lawn regardless of their choice.
Height Adjustability
For height adjustments, the MZK offers five cutting height settings ranging from 1.4 inches to 3 inches. The PowerSmart mower provides a broader range with six positions, adjustable from 1.5 inches to 3.9 inches. This slight advantage in the PowerSmart's height range allows users more flexibility to adapt to seasonal grass growth. The presence of adjustable heights in both models ensures that users can customize their cutting preferences effectively.
Maneuverability and Storage
The MZK mower is designed as a walk-behind push mower, making it lightweight and easy to maneuver, particularly in tight spaces. The PowerSmart mower, being self-propelled with a rear-wheel-drive system, offers enhanced traction on slopes and uneven terrain, simplifying the mowing process in challenging areas. Furthermore, the PowerSmart folds to save 70% storage space, making it convenient for users with limited storage options, while the MZK's lightweight design promotes ease of handling.
Customer Reception
The MZK mower enjoys a sales rank of 3,291, indicating a solid market presence, while the PowerSmart mower has a sales rank of 9,309. The higher ranking of the MZK suggests a greater level of customer satisfaction or popularity, which can be an important factor for potential buyers. However, both products have their unique strengths and target audiences, contributing to their respective market positions.
Which should you buy?
Choosing between the MZK 40V 16" Electric Lawn Mower and the PowerSmart Self Propelled Gas Lawn Mower ultimately depends on individual lawn care needs and preferences. For those seeking a budget-friendly, lightweight option that excels in small to medium spaces, the MZK is an excellent choice. Conversely, for users with larger lawns or uneven terrains who value versatility and self-propelled operation, the PowerSmart may justify its higher price tag. Both mowers have their merits, and understanding your specific requirements will guide you toward the best decision for your lawn maintenance.
