Overview of the Greenworks 80V 21” Brushless and PowerSmart Self Propelled Gas Lawn Mower
The Greenworks 80V 21” Brushless and PowerSmart Self Propelled Gas Lawn Mower cater to different preferences and needs in lawn care. The Greenworks model is a cordless electric option priced at $499.99, while the PowerSmart offers a gas-powered solution at $339.99. This price difference of about 47% highlights the different technology and features each mower brings to the table.
Power Source Comparison
The Greenworks 80V 21” Brushless operates on a robust 80V battery system, providing a cordless experience that eliminates the hassle of fuel and emissions. It includes two 2Ah batteries and a rapid charger, ensuring quick recharging times. In contrast, the PowerSmart is equipped with a 170cc OHV 4-cycle gas engine, relying on traditional fuel. While the gas mower is designed for consistent power, it requires more maintenance and presents challenges such as starting difficulties and fuel management.
Cutting Performance
In terms of cutting capability, the Greenworks mower features a 21-inch steel deck and a versatile 3-in-1 system that offers mulching, rear bagging, and side discharge options. This design allows for flexibility depending on lawn conditions. The PowerSmart also sports a 21-inch steel deck but emphasizes its deep dome design, which aids in better mulching. Both mowers provide efficient cutting, though the Greenworks' electric motor may offer quieter and smoother operation compared to the gas engine's noise and vibrations.
Maneuverability and Ease of Use
When it comes to maneuverability, the Greenworks 80V mower is hand-pushed, allowing for easy navigation without worrying about fuel or cords. Its adjustable height and LED lights enhance user convenience, especially in low-light conditions. The PowerSmart, on the other hand, features a self-propelled rear-wheel-drive system, making it easier to handle on uneven terrains and slopes. This self-propulsion can be a significant advantage for users with larger or hilly lawns, as it reduces user effort during operation.
Weight and Storage
The weight of the mowers plays a role in their usability and storage. While the exact weight of the Greenworks mower is not specified, the PowerSmart weighs 54 lbs, which is manageable for most users. The PowerSmart's foldable design allows for a 70% reduction in storage space, making it a practical choice for those with limited storage options. In contrast, the Greenworks mower's vertical storage capability is a beneficial feature, though it may not be as compact as the PowerSmart when folded.
Price Comparison
The Greenworks mower is priced at $499.99, while the PowerSmart comes in at $339.99, making the PowerSmart about 17% cheaper. This significant price difference can influence purchasing decisions, especially for budget-conscious consumers. The Greenworks model, however, includes more accessories, such as a leaf blower and string trimmer, which may justify its higher price for those looking for a comprehensive lawn care solution.
Warranty and Support
Warranty terms can greatly influence consumer confidence. The Greenworks 80V mower comes with a generous 4-year warranty, offering peace of mind regarding its durability and performance. On the other hand, the PowerSmart's warranty details are not specified in the provided information, which may leave potential buyers seeking more clarity. The longer warranty of the Greenworks gives it an edge in terms of long-term reliability assurance.
User Reviews and Sales Ranking
The Greenworks mower holds a sales rank of 16,803, while the PowerSmart ranks significantly higher at 9,309. This indicates that the PowerSmart may have a more favorable reception among consumers. While sales rank isn't the sole indicator of quality, it suggests that buyers may prefer the PowerSmart for its value and performance in the gas mower category.
Which should you buy?
Choosing between the Greenworks 80V 21” Brushless and the PowerSmart Self Propelled Gas Lawn Mower depends on your specific needs and preferences. If you prioritize a quiet, low-maintenance, and versatile electric option with a comprehensive kit, the Greenworks model is a solid choice. However, if you seek a powerful, self-propelled mower that is more budget-friendly, the PowerSmart is worth considering. Ultimately, your decision should reflect your lawn care requirements, budget, and preference for electric versus gas-powered equipment.
