Engine and Power Source
The AMERISUN 21 Inch Gas Push Lawn Mower is powered by a 144cc 4-stroke OHV engine, while the WEN 20V Max 19-Inch Cordless Brushless Lawn Mower utilizes a brushless motor paired with two 5Ah lithium-ion batteries. The gas engine provides consistent cutting performance ideal for small to medium yards, whereas the brushless motor offers superior performance, a longer lifespan, and reduced maintenance requirements. The AMERISUN mower is designed for those who prefer traditional gas-powered equipment, while the WEN model caters to environmentally conscious users looking for a cordless solution, eliminating the need for fuel and reducing carbon emissions.
Cutting Efficiency
In terms of cutting efficiency, the AMERISUN mower features a 21-inch cutting width, which allows for a broader swath and potentially faster mowing times. On the other hand, the WEN mower has a slightly smaller 19-inch deck but compensates with its 17-inch blade that rotates at up to 3100 RPM, making it effective for cutting through thick grass. Both mowers support height adjustments, but the AMERISUN offers six height positions, ranging from 1.5 to 3.9 inches, compared to the WEN's five settings from 1.5 to 3.2 inches. This means the AMERISUN provides slightly more versatility in adjusting to different grass types and conditions.
Weight and Maneuverability
The AMERISUN mower weighs 63 pounds, making it a lightweight option that is easy to maneuver. In contrast, although the WEN's exact weight isn’t specified, its design emphasizes portability with features like a collapsible handle for easier storage. The AMERISUN's lightweight design is advantageous for homeowners who need to navigate tight spaces or uneven terrain, while WEN's cordless design offers freedom from cords and gas, making it easier to move around larger yards without the hassle of managing fuel or cables.
Storage and Portability
For homeowners facing space constraints, storage and portability are significant considerations. The AMERISUN features a foldable handle that facilitates compact storage, making it easy to tuck away in garages or sheds. The WEN mower also has a collapsible handle and a lightweight design, making it easy to store upright. Both models prioritize user convenience, but the AMERISUN's lightweight nature may provide a slight edge in terms of transportability, especially for those who may need to carry their mower to different locations.
Runtime and Battery Life
The WEN mower boasts the capability to cut lawns up to 10,300 square feet on a single charge with its two included 5Ah batteries. Depending on grass conditions, the actual runtime can range from 30 to 68 minutes. In contrast, the AMERISUN, being gas-powered, does not have a specified runtime limitation but requires fuel, which needs to be managed separately. For users who prefer a more efficient and hassle-free experience without worrying about refueling, the WEN offers a compelling advantage with its battery operation and the convenience of switching out batteries for extended use.
Maintenance and Upkeep
Regarding maintenance, the AMERISUN's gas engine requires regular oil changes and proper care to keep it running smoothly, which can be seen as a drawback for some users. Conversely, the WEN's brushless motor requires less maintenance and provides a longer lifespan than traditional brushed motors. This difference points toward the WEN being more user-friendly for those looking to minimize upkeep, as it eliminates the need for gas, oil, and pull cords, making it a preferable option for less experienced users.
Price Comparison
The AMERISUN is priced at $224.99, while the WEN is slightly higher at $226.89. This means that the AMERISUN is about $1.90 cheaper, or roughly 0.84% less expensive than the WEN. Given their comparable features and performance capabilities, the price difference is minimal, making it essential for buyers to consider the type of power source and operational preferences when deciding which mower offers better value for their needs.
Which should you buy?
Ultimately, the choice between the AMERISUN 21 Inch Gas Push Lawn Mower and the WEN 20V Max 19-Inch Cordless Brushless Lawn Mower hinges on user preference for power sources and maintenance commitments. The AMERISUN is ideal for users who appreciate the reliability of gas power and a wider cutting deck, while the WEN caters to those seeking a cordless, low-maintenance solution with a focus on environmental impact. Your decision should align with your lawn size, mowing preferences, and how much maintenance you are willing to undertake.
