Design and Build Quality

When it comes to design and build quality, the Greenworks 80V 21" Self-Propelled Lawn Mower stands out with its durable steel deck and brushless motor, while the PowerSmart 21" 2-in-1 Push Lawn Mower is lightweight and compact. The Greenworks mower features a high-efficiency brushless motor that not only provides a longer lifespan but also operates quietly, making it a pleasant choice for residential areas. In contrast, the PowerSmart mower, weighing only 62 lbs, is designed for easy maneuverability, making it ideal for smaller yards and tight spaces. However, its construction does not boast the same level of durability as the Greenworks model.

Performance and Efficiency

The Greenworks mower boasts a brushless motor that generates 30% more torque than standard models, ensuring it can handle overgrown grass and tough terrain effectively. It is designed for large yards, capable of cutting up to half an acre on a single charge, which is impressive compared to the PowerSmart mower's robust 144cc engine. The PowerSmart mower, while efficient, is best suited for smaller lawns and offers a 2-in-1 cutting design for mulching and bagging. This makes it versatile but may not deliver the same endurance as the Greenworks model for extensive mowing tasks.

Cutting Versatility

The cutting versatility of both mowers caters to different user needs. The Greenworks mower features a 4-in-1 cutting system, allowing for mulching, bagging, side discharge, and turbo leaf pickup, making it a highly adaptable tool for various lawn care tasks. On the other hand, the PowerSmart mower provides a 2-in-1 capability focused on mulching and rear bagging, which is adequate for maintaining smaller lawns. The ability to switch between multiple cutting methods with the Greenworks mower provides a distinct advantage in achieving tailored lawn care results.

Ease of Use

In terms of ease of use, the Greenworks mower offers a self-propelled feature with rear-wheel drive and variable speed control, enhancing maneuverability across different terrains. This is particularly beneficial for users who may struggle with the physical demands of pushing a mower. The PowerSmart mower, while lightweight and easy to push, requires manual effort, which could be a drawback for some users. However, it does feature a start/stop control lever for added safety, making it user-friendly in emergency situations.

Battery Life and Power Source

The Greenworks mower operates on an 80V battery system that provides substantial power and flexibility. It is compatible with over 75 other Greenworks tools, allowing for a broader investment in outdoor equipment. The 4.0Ah battery can handle extensive mowing without interruption. Conversely, the PowerSmart mower relies on a traditional 144cc gas engine, which, while powerful, requires fuel and regular maintenance. The convenience of a cordless system like that of the Greenworks mower appeals to those looking for an eco-friendly and hassle-free lawn care experience.

Price Point

When considering price, the Greenworks 80V mower retails for $479.99, while the PowerSmart mower is priced at $279.99, making it about 17% cheaper. This significant price difference can be a deciding factor for budget-conscious consumers. However, while the PowerSmart mower is more affordable, the Greenworks model offers advanced features and greater performance capabilities that may justify its higher cost for those with larger yards or more demanding mowing needs.

Customer Reception

Customer reception for the Greenworks mower is notably higher, reflected in its current sales rank of 1,880, compared to the PowerSmart mower, which holds a rank of 18,759. This suggests that the Greenworks mower is favored among consumers, likely due to its robust performance and innovative features. The Greenworks mower's superior technology and efficiency have garnered positive feedback, making it a popular choice for homeowners looking for dependable lawn care equipment.

Which should you buy?

Choosing between the Greenworks 80V 21" Self-Propelled Cordless Lawn Mower and the PowerSmart 21" 2-in-1 Push Lawn Mower ultimately depends on your specific lawn care needs. If you require a powerful, enduring mower with advanced features and versatility for larger yards, the Greenworks mower is an excellent investment, albeit at a higher price point. However, if you have a smaller lawn and are looking for a more budget-friendly option that still delivers solid performance, the PowerSmart mower could be the right fit. Evaluate your lawn size, desired features, and budget to make the best choice for your mowing needs.
