AMERISUN AMRISUN 21-Inch Self-Propelled Gas Lawn Mower forMZK 20V 13" Electric Lawn Mower, Brushless

Engine Type

The AMRISUN 21-Inch Self-Propelled Gas Lawn Mower operates with a powerful 170cc 4-stroke gas engine, providing strong cutting performance suitable for medium to large yards. In contrast, the MZK 20V 13" Electric Lawn Mower utilizes a brushless motor powered by 4Ah batteries, offering an efficient and maintenance-free operation. This difference in engine type means that the AMRISUN is better suited for extensive mowing tasks, while the MZK provides a quieter and more eco-friendly alternative.

Cutting Width

The AMRISUN features a 21-inch cutting width, allowing it to cover more ground in fewer passes, which is beneficial for larger lawns. On the other hand, the MZK has a narrower 13-inch cutting width, making it ideal for smaller yards or intricate landscaping. The wider cutting deck of the AMRISUN is advantageous for those looking to complete mowing sessions more quickly, while the MZK's smaller size enhances maneuverability in tight spaces.

Adjustable Cutting Heights

In terms of adjustable cutting heights, the AMRISUN offers six different settings ranging from 1.5 inches to 3.9 inches, allowing for greater customization based on grass type and seasonal growth. The MZK provides four adjustable heights, from 1.2 inches to 1.5 inches. This means that while the AMRISUN can cater to a wider range of cutting needs, the MZK’s options may be more limited for taller grass, making the AMRISUN a more versatile choice for various lawn conditions.

Weight and Maneuverability

When it comes to weight and maneuverability, the MZK is significantly lighter, weighing only 24.3 pounds, which makes it easy to transport and maneuver. The AMRISUN, while not specified in weight, is a self-propelled mower designed for larger lawns, likely making it heavier. The lightweight design of the MZK is particularly beneficial for users of all ages who may experience strain during mowing. This aspect may make the MZK preferable for those who prioritize ease of use and transport.

Grass Bag Capacity

The AMRISUN is equipped with a 1.4-bushel grass catcher, which allows for ample collection of grass clippings during mowing. In comparison, the MZK features an 8-gallon grass bag, providing a significant amount of space for clippings as well. However, the AMRISUN's larger catcher potentially reduces the number of trips needed to empty it, which can be an important factor for those maintaining larger lawns, while the MZK's capacity is still adequate for smaller yards.

Price Comparison

The AMRISUN is priced at $314.10, while the MZK is more budget-friendly at $149.99. This price difference makes the MZK about 52% cheaper than the AMRISUN, which is a considerable factor for budget-conscious consumers. However, the investment in the AMRISUN may be justified for those needing a more robust mower for larger areas, while the MZK offers a great entry point for casual users or those with smaller lawns.

Sales Rank and Popularity

The AMRISUN has a sales rank of 13,987, indicating it is less popular compared to the MZK, which boasts a much better sales rank of 3,019. This suggests that the MZK is more favored among consumers, possibly due to its affordability and ease of use. A higher bestseller rank like that of the MZK often reflects customer satisfaction and could indicate a more reliable product choice for new buyers.

Which should you buy?

Choosing between the AMRISUN 21-Inch Self-Propelled Gas Lawn Mower and the MZK 20V 13" Electric Lawn Mower ultimately depends on your specific needs. If you have a large yard and require a powerful gas mower that can handle varied terrains, the AMRISUN may be the better option despite its higher price. Conversely, if you are looking for a lightweight, cost-effective solution for a smaller space, the MZK is a compelling choice, offering ease of use and a decent runtime for basic lawn care tasks.
