Greenworks 80V 21" Self-Propelled Cordless Lawn vs PowerSmart Self Propelled Gas Lawn Mower 21-inch
Updated July 2026 — full head-to-head comparison.
Price Comparison
When it comes to price, the PowerSmart Self Propelled Gas Lawn Mower is about 29% cheaper than the Greenworks 80V Self-Propelled Cordless Lawn Mower. The Greenworks model is priced at $479.99, while the PowerSmart variant costs $339.99. This significant price difference may appeal to budget-conscious consumers looking to get quality lawn care without breaking the bank. While both mowers offer unique features, the lower price of the PowerSmart model makes it an attractive option for those who might not need the advanced capabilities of the Greenworks mower.
Power and Performance
In terms of power, the Greenworks mower is equipped with a brushless motor that delivers 30% more torque than standard motors, making it highly efficient for tackling tough grass and uneven terrain. On the other hand, the PowerSmart features a 170cc 4-cycle OHV engine that provides reliable performance and easy starting, which is essential for gas-powered mowers. While both models are self-propelled, the Greenworks mower's electric motor offers a quieter experience—three times quieter than gas mowers—making it ideal for early morning or evening mowing without disturbing the neighborhood.
Cutting Efficiency
The cutting efficiency of each mower is noteworthy, with both models featuring a 21-inch cutting deck. The Greenworks mower provides a 4-in-1 cutting system, allowing users to mulch, bag, side discharge, or perform turbo leaf pickup. This versatility can be particularly beneficial for homeowners who want to adapt their lawn care based on seasonal needs. In contrast, the PowerSmart mower also offers a 3-in-1 system, allowing for mulching, side discharge, and rear-bagging, making it a solid choice for varied mowing tasks. Each mower has its strengths, but the Greenworks mower stands out for its additional operational options.
Maneuverability
Maneuverability is a crucial factor when choosing a lawn mower, and both models excel in this area. The Greenworks mower is designed with rear-wheel drive and variable speed control, providing maximum traction and control on hilly or uneven terrain. Meanwhile, the PowerSmart mower features a rear-wheel-drive system with a single speed range of 3.5-4.1 km/h, which also aids in maintaining traction on slopes. Although both mowers are designed for easy handling, the Greenworks model offers greater adaptability thanks to its variable speed feature, allowing users to adjust their pace based on the mowing conditions.
Durability and Build Quality
Durability is another essential aspect of lawn mowers, and both the Greenworks and PowerSmart models are built to last. The Greenworks mower features a durable steel deck and a brushless motor designed for longevity and reduced noise. In comparison, the PowerSmart mower is also constructed with a rugged all-steel deck, which ensures it can withstand regular use. Both models emphasize quality in their build, but the Greenworks mower's advanced motor technology may provide it with a longer lifespan and more efficient operation over time.
User Experience
User experience can significantly affect satisfaction with a lawn mower. The Greenworks mower's design includes high visibility LED lights, making it easier to mow during early mornings or late evenings. This feature enhances usability, especially for those with busy schedules. The PowerSmart mower, on the other hand, boasts a foldable design that saves 70% of storage space, which is a convenient feature for users with limited garage space. While both mowers offer user-friendly elements, the Greenworks model's LED lights add significant value for those who prioritize night-time mowing.
Maintenance and Care
In terms of maintenance, both mowers require different levels of care. The Greenworks mower, being electric, eliminates the need for gas and oil changes, making it a low-maintenance option. Additionally, its brushless motor is designed to last longer with minimal maintenance compared to conventional gas engines. On the contrary, the PowerSmart mower, with its gas engine, will require occasional maintenance tasks such as oil changes and spark plug replacements. This difference in maintenance needs could influence buyers who prefer a hassle-free lawn care solution.
Which should you buy?
Ultimately, the choice between the Greenworks 80V Self-Propelled Cordless Lawn Mower and the PowerSmart Self Propelled Gas Lawn Mower depends on your specific needs and budget. If you’re looking for a more powerful, versatile, and quieter mower with advanced features, the Greenworks model is worth the investment at $479.99. However, if you’re seeking a reliable and budget-friendly option for maintaining a small to medium yard, the PowerSmart mower at $339.99 provides excellent value without compromising on essential features. Each mower has its unique strengths, so consider your lawn care priorities before making a decision.
