Price Comparison

The GasXcel 21" Self-Propelled Lawn Mower is priced at $389.99, making it about 17% cheaper than the Greenworks 80V 21” Brushless, which retails for $499.99. This price difference can be significant for budget-conscious consumers looking for a reliable lawn mower without breaking the bank. While both mowers offer unique features and benefits, the GasXcel provides a cost-effective option for homeowners who prioritize value without sacrificing performance.

Power and Performance

When it comes to power, the Greenworks 80V Brushless mower leads with its robust 80V brushless motor. This motor ensures efficient and reliable performance, making it suitable for various lawn maintenance tasks. In contrast, the GasXcel is equipped with a 170cc OHV engine, which offers solid power for residential use but may not match the electric mower's efficiency. If you have a larger yard or tougher grass, the Greenworks may handle the job more effectively, while the GasXcel is better suited for standard-sized lawns.

Cutting System

The GasXcel features a versatile 4-in-1 cutting system that includes mulching, rear bagging, side discharge, and rear discharge, providing homeowners with greater flexibility in lawn care. This system allows users to adapt to different grass conditions and seasonal needs seamlessly. Meanwhile, the Greenworks mower offers a 3-in-1 system—mulching, rear bagging, and side discharge. While both systems are effective, those seeking comprehensive lawn control may find the GasXcel's additional cutting option more appealing.

Grass Collection and Handling

The GasXcel is designed with a large 65L (17.5-gallon) grass collection bag, which reduces the frequency of stops during mowing. This feature, combined with its self-propelled drive, makes it easier to maneuver across uneven terrain. On the other hand, the Greenworks mower includes a more compact design, which may be easier to store but offers a smaller grass collection capacity. For users who prefer fewer interruptions while mowing, the GasXcel may provide a more efficient experience.

User Experience and Comfort

For user comfort, both mowers offer features that enhance the mowing experience. The GasXcel has a self-propelled drive that reduces the effort needed on slopes, alongside a precision 7-position height adjustment for customized cutting. The Greenworks mower also boasts a 7-position height adjustment but prioritizes user-friendliness with its hand-push design and LED lights for low-light conditions. While both models cater to comfort, the self-propelled feature of the GasXcel may be more beneficial for users dealing with challenging terrains.

Battery and Power Source

The Greenworks mower is a cordless electric model that operates on two 2Ah batteries with a rapid charger, providing the convenience of hassle-free cordless operation. This setup appeals to users who prefer the absence of gas emissions and the ease of starting an electric mower. Conversely, the GasXcel operates on a gas engine, which may necessitate more maintenance but offers the advantage of extended run time without the need for recharging. For those who prioritize convenience and eco-friendliness, the Greenworks mower stands out, while the GasXcel may be favored by users comfortable with traditional gas mowers.

Additional Features

In addition to their core functionalities, both mowers come with unique additional features. The Greenworks package includes not just the lawn mower but also a 500 CFM axial leaf blower and a 13-inch string trimmer, making it a comprehensive lawn care solution. This combination is particularly useful for homeowners looking to invest in multiple tools for yard maintenance. Meanwhile, the GasXcel focuses solely on the mowing experience but emphasizes durability with its high-carbon steel blade and foldable design for easy storage. Customers may prefer the Greenworks for its all-in-one approach, while the GasXcel appeals to those wanting a focused, powerful mower.

Which should you buy?

Choosing between the GasXcel 21" Self-Propelled Lawn Mower and the Greenworks 80V 21” Brushless mower depends on your specific needs and preferences. The GasXcel is a more budget-friendly option that excels in power and cutting versatility, making it ideal for users with standard lawns who appreciate additional features like the 4-in-1 cutting system and large grass collection capacity. On the other hand, the Greenworks mower offers modern convenience with its cordless operation and comprehensive tool package, making it suitable for those who prioritize user-friendliness and eco-friendliness. Ultimately, your choice should reflect your lawn care requirements and whether you value cost savings or the convenience of a multi-tool system.
