Overview of the Two Lawn Mowers
When choosing between the GasXcel 21" Self-Propelled Lawn Mower and the Greenworks 40V 17" Cordless Lawn Mower, consumers must consider power sources, capabilities, and price. The GasXcel model, priced at $389.99, is a gas-powered option aimed at larger yards, while the Greenworks model, at $279.99, offers a cordless alternative that's easier to handle for smaller spaces. This means that budget-conscious buyers may find the Greenworks model about 28% cheaper than the GasXcel.
Engine and Power Source
The GasXcel lawn mower is equipped with a powerful 170cc OHV engine, delivering reliable performance for residential yards. It promises a runtime of up to 1.5 hours on a full tank, making it suitable for extensive mowing tasks. In contrast, the Greenworks lawn mower operates on a 40V battery, providing about 35 minutes of runtime per charge with its included 4.0Ah battery. This difference in power sources reflects a trade-off between extended usage and convenience, as the GasXcel requires fuel, while the Greenworks eliminates the need for gas entirely.
Cutting Performance
In terms of cutting capabilities, the GasXcel features a 4-in-1 cutting system that allows for mulching, rear bagging, side discharge, and rear discharge. This versatility is ideal for adapting to various grass conditions and seasons. The Greenworks model, however, offers a 2-in-1 functionality, allowing users to mulch or bag clippings. While the GasXcel's options provide greater flexibility, the Greenworks is designed for ease of use, especially for smaller yards where quick adjustments may be more advantageous.
Maneuverability and Ease of Use
Maneuverability differs significantly between the two models. The GasXcel is a self-propelled mower, which means it reduces the effort needed to push on slopes or uneven terrain. This is complemented by its large 65L grass bag, allowing for less frequent stops during mowing. The Greenworks, on the other hand, has a lightweight design that makes it easy to push, but it does not have a self-propelled feature. This could make the GasXcel a more suitable option for those dealing with larger or more challenging landscapes.
Cutting Heights and Adjustability
The GasXcel offers a precision 7-position height adjustment ranging from 1" to 3", allowing users to customize their cutting height based on grass type and lawn preferences. This feature is particularly beneficial for achieving a professional-looking cut. Meanwhile, the Greenworks provides 6 cutting heights that can be adjusted with a single lever. While both options offer adjustability, the GasXcel’s broader range may appeal to those who prioritize versatility in lawn care.
Noise and Maintenance
One of the standout features of the Greenworks lawn mower is its brushless motor, which operates 30% quieter than traditional gas mowers. This characteristic makes it an excellent choice for residential areas where noise could be a concern. Additionally, the Greenworks model requires zero maintenance, with no oil changes or pull cords. In contrast, the GasXcel, while powerful, necessitates regular maintenance typical of gas engines, which may deter some users seeking a hassle-free option.
Storage and Portability
Storage and portability are essential factors for many homeowners. The GasXcel’s foldable design allows it to be compactly stored, reducing its footprint to 36"L x 28"W x 21"H when not in use. This makes it suitable for garages or sheds with limited space. The Greenworks model, being cordless and lightweight, is also easy to store and transport. While both mowers have their advantages in this regard, the GasXcel’s foldable feature provides a slight edge for those with storage constraints.
Which should you buy?
Ultimately, the decision between the GasXcel 21" Self-Propelled Lawn Mower and the Greenworks 40V 17" Cordless Lawn Mower hinges on individual needs and preferences. The GasXcel is ideal for larger yards requiring significant power and versatility, while the Greenworks is better suited for smaller spaces and users seeking convenience and quieter operation. With a price difference of about $110, the Greenworks offers considerable savings, making it a compelling choice for budget-minded consumers. Each model excels in different areas, so the best choice will depend on your specific lawn care requirements.
