Overview of the AMERISUN and WEN Lawn Mowers
The AMERISUN 21-Inch 3IN1 Push Gas Lawn Mower is priced at $238.49, while the WEN 20V Max 2-in-1 19-Inch Cordless Brushless Lawn Mower comes in at $226.89, making it approximately 5% cheaper. Both mowers serve the primary function of cutting grass but do so in fundamentally different ways, appealing to varying user preferences. The AMERISUN operates on gas, while the WEN is a cordless, battery-powered model. This key difference shapes their performance, maintenance, and suitability for different types of yards.
Power and Performance
The AMERISUN mower features a powerful 144cc 4-stroke OHV engine, delivering robust cutting performance. This gas mower is designed for small to medium yards, ensuring smooth operation with its easy-start recoil system. On the other hand, the WEN mower utilizes a brushless motor, which not only enhances performance but also extends the lifespan of the machine while reducing maintenance needs. The brushless motor operates at up to 3100 RPM with its 17-inch blade, effectively tackling even thick grass. In terms of sheer power, the AMERISUN might have the edge for those who prioritize raw cutting capability, while the WEN offers a more environmentally friendly option without sacrificing performance.
Cutting Width and Height Adjustability
The AMERISUN features a 21-inch rust-resistant steel deck that allows for a wider cutting path, compared to the WEN's 19-inch deck. This larger cutting width means that the AMERISUN can cover more ground with each pass. Additionally, the AMERISUN offers 6 adjustable cutting heights ranging from 1.5 to 3.9 inches, providing flexibility for various lawn conditions. In contrast, the WEN provides five height settings between 1.5 and 3.2 inches. Thus, while the AMERISUN offers a broader cutting width and greater height variability, the WEN still provides sufficient adjustability for typical lawn care tasks.
Versatility in Mowing Functions
The AMERISUN is a versatile 3-in-1 mower that allows for mulching, bagging, and side discharge, catering to different lawn care needs. Its 1.4-bushel grass catcher facilitates easy cleanup, making it efficient for users who prefer a tidy lawn. Meanwhile, the WEN mower doubles as both a mower and a mulcher, and it includes a 13-gallon collection bag. This dual functionality is excellent for those who want to quickly switch between mowing and mulching without needing additional attachments. Both mowers offer unique advantages, but the AMERISUN's additional side discharge feature may appeal to those looking for more options in lawn maintenance.
Ease of Use and Maneuverability
At 68 lbs, the AMERISUN is lightweight and designed for easy maneuverability with its durable wheels and foldable handle for compact storage. However, the WEN’s cordless design eliminates the need for gas, oil, or pull cords, contributing to a hassle-free mowing experience. The collapsible handle of the WEN also enhances its portability and ease of storage. While both mowers are designed for user convenience, the WEN's battery operation allows for more straightforward handling without the weight of fuel and the complexities of gas maintenance.
Runtime and Battery Efficiency
The WEN mower includes two 5Ah lithium-ion batteries that allow for a runtime of 30 to 68 minutes, depending on grass conditions and cutting height. This capability enables it to cover lawns up to 10,300 square feet on a single charge, making it suitable for larger residential areas. Although the AMERISUN does not rely on a battery, its gas engine ensures that users can mow continuously without downtime for recharging. For those with larger lawns who prefer the convenience of a cordless mower, the WEN provides a significant benefit in battery efficiency, while the AMERISUN offers the advantage of unlimited runtime.
Maintenance and Longevity
Maintenance is a crucial factor for lawn mowers. The AMERISUN, being a gas mower, may require regular oil changes, spark plug replacements, and fuel management, which can complicate upkeep. Conversely, the WEN’s brushless motor involves less maintenance, as it does not require oil changes or fuel management, making it a more user-friendly option in the long run. This lower maintenance need can be appealing for homeowners looking to simplify yard work and minimize time spent on mower upkeep.
Price Comparison
The AMERISUN is priced at $238.49, while the WEN is available for $226.89, making the WEN about $11.60 cheaper. This price difference may influence buyers who are budget-conscious, particularly since the WEN also comes with two 5Ah batteries and a dual-port charger, adding to its overall value. The AMERISUN, while slightly more expensive, offers a gas-powered solution that some may prefer for its cutting power and runtime capabilities. The decision may ultimately depend on individual preferences regarding power source and lawn care needs.
Which should you buy?
Choosing between the AMERISUN and the WEN lawn mowers depends largely on your specific needs and preferences. If you prefer the power and performance of a gas mower and require a wider cutting width with versatile mowing options, the AMERISUN may be the better choice for you. However, if you value convenience, lower maintenance, and the environmental benefits of cordless operation, the WEN stands out as a strong contender. Ultimately, both mowers offer unique features that cater to different user preferences, making either a solid investment for lawn care.
