Price Comparison

The Greenworks 60V 21" Self-Propelled Cordless Lawn Mower is priced at $538.00, while the PowerSmart Self Propelled Gas Lawn Mower retails for $339.99. This means the Greenworks mower is approximately 58% more expensive than the PowerSmart model. Despite the higher price, the Greenworks mower offers advanced features such as a brushless motor and two batteries, which may justify the cost for those seeking a more powerful and eco-friendly option. On the other hand, the PowerSmart mower presents a more budget-friendly choice for those who prioritize cost over additional features.

Power Source

The Greenworks mower is powered by a 60V lithium-ion battery system, offering the convenience of cordless operation and zero emissions. This battery system allows for up to 60 minutes of continuous mowing, covering up to three-quarters of an acre per charge. In contrast, the PowerSmart mower is equipped with a 170cc gas engine, providing robust power for cutting through tough grass and uneven terrain. While gas engines typically require more maintenance and emit emissions, they can be advantageous for users who prefer longer run times without the need to recharge batteries, especially in larger yards.

Mowing Capability

The Greenworks mower boasts a brushless motor that operates at 3200 RPM, providing gas-like power for efficient cutting. It features a 4-in-1 versatility option that allows for mulching, bagging, side discharge, and turbo leaf pickup. This flexibility makes it suitable for various mowing conditions. The PowerSmart mower, with its 21-inch steel deck and a superior mulching blade, is designed for efficiency and durability. It also features a 3-in-1 capability, allowing for mulching, side discharge, or rear-bagging options. However, while the PowerSmart mower can handle typical mowing tasks effectively, it may not match the cutting performance of the Greenworks mower in tougher conditions.

Ease of Use

The Greenworks mower is designed for effortless operation with its self-propelled rear-wheel drive system, allowing users to adjust their speed on-the-go. This feature is particularly beneficial for tackling slopes and thick grass without the need for pushing. Additionally, it operates three times quieter than gas mowers, making it ideal for noise-sensitive environments. The PowerSmart mower also features a self-propelled rear-wheel-drive system, providing good traction on inclines. However, its design may not be as user-friendly or quiet as the Greenworks model, which could impact the overall mowing experience.

Maintenance Requirements

The Greenworks mower is virtually maintenance-free, requiring no oil changes or spark plug replacements, significantly reducing upkeep time and costs. Its battery-powered system also means no fuel storage or engine maintenance, making it a hassle-free option for users. In contrast, the PowerSmart mower, being gas-powered, requires regular maintenance such as oil changes and spark plug replacements, which can add to the long-term cost and effort of ownership. Users who prefer a low-maintenance option may find the Greenworks mower more appealing in this regard.

Durability and Construction

The Greenworks mower features a robust design with IPX4-rated waterproof construction, making it resilient against rain and ensuring longevity. The rust-proof aluminum handles further enhance its durability, allowing for years of dependable use. On the other hand, the PowerSmart mower is built with a rugged 21-inch all-steel deck, providing solid performance and durability. While both mowers are constructed to withstand regular use, the Greenworks mower's advanced materials may offer better protection against the elements, potentially leading to a longer lifespan.

User Experience

With a bestseller rank of 5665, the Greenworks mower has garnered positive reviews for its performance, quiet operation, and eco-friendly features. Users appreciate the convenience of its dual 4.0Ah batteries and the speed adjustment feature, which enhances the mowing experience. The PowerSmart mower, with a bestseller rank of 9309, is noted for its ease of operation and affordability. However, some users may find it less efficient in handling tough grass compared to the Greenworks model. Both products have their strengths, but the user experience may vary significantly based on individual preferences and yard conditions.

Which should you buy?

Choosing between the Greenworks 60V 21" Self-Propelled Cordless Lawn Mower and the PowerSmart Self Propelled Gas Lawn Mower ultimately depends on your specific needs. If you prioritize eco-friendliness, low maintenance, and advanced features, the Greenworks mower is worth the higher price tag at $538.00. However, if you are looking for a more budget-friendly option that still offers solid performance for smaller to medium yards, the PowerSmart mower at $339.99 could be the better choice. Consider your mowing requirements, budget, and maintenance preferences before making your decision.
