Greenworks 40V 16" Cordless Lawn Mower vs PowerSmart EasyGlide 21-Inch Gas Lawn Mower, 144cc

Power Source and Runtime

The Greenworks 40V 16" Cordless Lawn Mower offers the clear advantage of cordless electric power with a 40-minute runtime from a single 4.0Ah battery, while the PowerSmart EasyGlide 21-Inch Gas Lawn Mower relies on a traditional 144cc 4-stroke OHV gas engine. Greenworks' battery-powered mower eliminates the need for gas or oil, providing zero emissions and quieter operation under 75 dB, making it ideal for environmentally conscious users and noise-sensitive neighborhoods. The battery recharges fully in just two hours, supporting up to a half-acre yard or about 1/3 acre efficiently.

In contrast, the PowerSmart mower’s gas engine offers reliable high performance and longer working life, but it requires gas refills, oil changes, and more routine maintenance. While it may run longer without needing a recharge, it also produces emissions and more noise. Overall, if you prioritize convenience, eco-friendliness, and quieter mowing, Greenworks leads with its cordless electric design and 40-minute runtime.

Cutting Width and Maneuverability

The PowerSmart EasyGlide features a larger 21-inch steel cutting deck compared to the Greenworks’ 16-inch deck. This means the PowerSmart can cover more ground in a single pass, which is beneficial for larger lawns or faster mowing sessions. The Greenworks mower’s smaller deck, however, contributes to its ultra-lightweight design, making it 35% lighter and easier to handle, especially on uneven terrain or multi-level yards.

Maneuverability is further enhanced in Greenworks with ergonomic handles and a push-button start, simplifying operation for users who prioritize comfort and ease of storage. PowerSmart’s mower compensates with larger 8-inch rear and 7-inch front double ball-bearing wheels, designed to smooth control and ease pushing across the yard. Thus, PowerSmart’s wider cut may reduce mowing time, but Greenworks excels in lightweight agility and user-friendly handling.

Cutting Height and Grass Management

When it comes to cutting height adjustment, Greenworks offers a single-lever system with five positions ranging from 1.25 to 3.375 inches. This Smart Cut Adjustment system provides straightforward adaptability to different grass types and user preferences. PowerSmart, meanwhile, provides a dual-lever height adjustment with six positions from 1.5 to 3.9 inches, offering a slightly wider range and finer control over cutting height.

Both mowers support multiple grass clipping management options. Greenworks features a 2-in-1 mulching and rear-bagging system, while PowerSmart offers a versatile 3-in-1 function including mulching, bagging, and side discharge. This gives PowerSmart users additional flexibility for dealing with varying grass conditions and cleanup preferences, particularly useful for taller or thicker grass.

Maintenance and Operating Costs

Greenworks clearly stands out for zero maintenance requirements due to its electric motor. Users avoid ongoing expenses related to gas, oil, tune-ups, and engine parts. This translates to savings exceeding $200 annually compared to gas mowers, making Greenworks a cost-effective choice in the long run. Its quieter operation also reduces noise pollution, benefiting both the user and neighbors.

On the other hand, PowerSmart’s gas-powered engine demands regular maintenance, including fuel refills, oil changes, and occasional engine servicing. While gas mowers may offer raw power and durability, their upkeep and fuel costs add to total ownership expenses. For buyers sensitive to ongoing costs and environmental impact, Greenworks is the more economical and eco-friendly option.

Build Quality and Durability

PowerSmart’s 21-inch mower is constructed with a durable steel deck, designed to withstand tough yard work and extend its lifespan. The 144cc 4-stroke OHV engine is engineered with a stabilized body structure to maximize durability and consistent performance. These features suggest PowerSmart aims to deliver a rugged machine capable of handling demanding conditions.

Greenworks, in contrast, focuses on lightweight materials to prioritize ease of use and storage rather than heavy-duty construction. While its build is sufficient for small to medium lawns, it may not match the long-term toughness of a steel-deck gas mower. Buyers seeking a robust, heavy-duty mower with a larger cutting width might favor PowerSmart for its solid construction.

Price and Value for Money

At the time of this comparison, the Greenworks 40V 16" Cordless Lawn Mower is priced at $279.99, which is about $10 cheaper than the PowerSmart EasyGlide 21-Inch Gas Lawn Mower at $289.99. Over the last 90 days, PowerSmart’s average price was $339.17, notably higher than Greenworks’ $241.05 average, indicating better historical value with the cordless model.

Considering the included accessories, Greenworks comes with a 4.0Ah battery, charger, grass bag, and a 3-year warranty on both the tool and battery, which enhances its overall value. PowerSmart does not list included accessories or warranty details in this data. For buyers focused on upfront price and included extras, Greenworks offers a compelling bundle at a slightly lower price point.

Noise and Environmental Impact

Greenworks operates quietly at less than 75 decibels, making it suitable for early morning or late evening mowing without disturbing neighbors. Its electric motor produces zero emissions during use, contributing to a cleaner and more environmentally responsible lawn care routine. This quiet, gas-free operation appeals to those living in communities with noise restrictions or who seek sustainable alternatives.

Conversely, PowerSmart’s gas engine generates typical noise and emissions associated with combustion engines. While it provides consistent power, it may not be ideal for noise-sensitive areas or environmentally conscious users. Those prioritizing a silent, greener mowing experience will find Greenworks clearly superior in this category.

Which should you buy?

Choosing between the Greenworks 40V 16" Cordless Lawn Mower and the PowerSmart EasyGlide 21-Inch Gas Lawn Mower depends largely on your yard size, maintenance preferences, and environmental priorities. Greenworks excels for small to medium lawns (up to 1/3 acre) with its lightweight design, quiet operation, and zero maintenance, plus the convenience of cordless power and a 40-minute runtime. It also offers better value through included battery, charger, and warranty.

PowerSmart, with its larger 21-inch steel deck and durable 144cc gas engine, suits users with bigger yards or those who need longer continuous mowing without battery recharge. It offers more cutting height positions and 3-in-1 clipping management, useful for tougher mowing conditions but demands more upkeep and fuel costs.

If you prioritize ease of use, low operating costs, and environmental friendliness, the Greenworks mower is the better buy. If you need raw power, extended runtime without recharge, and a heavy-duty build for larger yards, PowerSmart is the way to go.
