AMERISUN AMRISUN 21-Inch Self-Propelled Gas Lawn Mower forWEN 20V Max 2-in-1 19-Inch Cordless Brushless Lawn

Overview

When looking for a reliable lawn mower, the AMRISUN 21-Inch Self-Propelled Gas Lawn Mower and the WEN 20V Max 2-in-1 Cordless Brushless Lawn Mower stand out as two great options. The AMRISUN is priced at $314.10 while the WEN is about 17% cheaper at $226.89. Each mower offers unique features catering to different user preferences and yard sizes.

Engine and Power Source

The AMRISUN mower features a powerful 170cc 4-stroke gas engine, providing strong cutting performance for medium to large yards. Its design ensures easy starting and efficient operation, making it suitable for extensive landscaping tasks. In contrast, the WEN mower operates on a cordless system powered by two 5Ah lithium-ion batteries. This offers the convenience of no gas or oil, making it an eco-friendly choice. The brushless motor in the WEN mower not only enhances performance but also reduces maintenance, providing a longer lifespan compared to traditional motors.

Cutting Performance

The AMRISUN mower boasts a versatile 3-in-1 mowing function that allows users to mulch, side discharge, or collect grass clippings in a rear bag. This flexibility can be particularly useful for maintaining large yards and achieving a professional finish. The cutting height is adjustable with six positions ranging from 1.5 to 3.9 inches, accommodating various lawn types. Meanwhile, the WEN mower also offers adjustable cutting heights, with five quick settings from 1.5 to 3.2 inches. Although it has a slightly smaller cutting width of 19 inches compared to the AMRISUN's 21 inches, it cuts lawns up to 10,300 square feet on a single charge, making it efficient for medium-sized areas.

Maneuverability

Maneuverability is crucial in lawn mowing, and the AMRISUN design excels here with its high-wheel self-propelled feature. The mower is equipped with 10-inch rear and 7-inch front wheels, allowing it to glide smoothly over uneven terrain, hills, and slopes. This is particularly beneficial for users with challenging landscapes. The WEN mower, while not self-propelled, includes 8-inch rear wheels that provide decent traction and ease in navigating tougher lawns. Its lightweight and collapsible handle also make it easy to transport and store, though it lacks the self-propelling advantage.

Storage and Portability

When it comes to storage and portability, the WEN mower takes the lead with its collapsible handle, allowing for easy upright storage. The inclusion of a 13-gallon collection bag further enhances its convenience. In contrast, the AMRISUN mower features a foldable handle, but its weight and bulkiness may make it less portable than the WEN. Users looking for a mower that is easy to store and transport may find the WEN a more suitable option, especially in smaller garages or sheds.

Maintenance and Care

Maintenance is a significant factor when selecting a lawn mower. The AMRISUN’s gas engine requires regular maintenance, including oil changes and spark plug replacements, which can be time-consuming. However, its robust design may offer long-term durability. On the other hand, the WEN mower’s brushless motor requires less maintenance and eliminates the need for gas and oil entirely, appealing to users who prefer a hassle-free experience. This makes the WEN mower a practical choice for those who want to minimize upkeep.

Price Comparison

The AMRISUN 21-Inch Self-Propelled Gas Lawn Mower is priced at $314.10, while the WEN 20V Max Cordless Brushless Lawn Mower comes in at $226.89. This represents a difference of about $87.21, making the WEN significantly cheaper. Given their respective features, users need to weigh if the additional investment in the AMRISUN is justified by its gas engine and self-propelled capabilities. For those on a budget, the WEN provides excellent value without compromising on essential lawn care functionality.

Which should you buy?

Ultimately, the choice between the AMRISUN 21-Inch Self-Propelled Gas Lawn Mower and the WEN 20V Max 2-in-1 Cordless Brushless Lawn Mower comes down to your specific needs and preferences. If you prioritize power, cutting width, and self-propulsion for a large yard, the AMRISUN is a robust option despite its higher price. However, if you are looking for a more budget-friendly and eco-conscious alternative with less maintenance, the WEN mower presents a compelling case. Consider your lawn size, terrain, and maintenance preferences to make the best choice for your mowing needs.
