PowerSmart vs WORX Spec Showdown
Power Source
The PowerSmart 18-Inch model relies on a 144cc 4-cycle gas engine. This setup provides consistent power without worrying about battery charge levels, but it requires fuel mixing and maintenance. In contrast, the WORX 21-Inch mower uses a 40V cordless battery system. It comes with two 20V 5.0Ah PowerShare Pro batteries. This electric approach offers quieter operation and zero emissions. You avoid gas fumes and oil changes. The choice depends on whether you prefer the unlimited runtime of gas or the convenience of rechargeable power.
Cutting Width
Cutting width determines how much grass you cover in a single pass. The PowerSmart mower features an 18-inch steel deck. This narrower width is easier to maneuver around tight obstacles like flower beds and small trees. The WORX mower offers a wider 21-inch cutting deck. This additional width allows you to cover more ground with fewer passes, which can save time on larger lawns. The WORX design is also noted to be efficient for areas up to half an acre. If speed is your priority, the wider deck has a clear advantage.
Mowing Function
How you handle grass clippings matters for lawn health and cleanup. The PowerSmart model is configured for side discharge only. This method is efficient for tall or thick grass, as it quickly ejects clippings to prevent clogging. The WORX mower provides 3-in-1 functionality. You can mulch, bag, or use the rear side-discharge chute. This versatility allows you to recycle nutrients back into the lawn or collect clippings for disposal. The WORX includes the necessary mulch plug and discharge chute for these modes, giving you more options for different lawn conditions.
Deck Material
The durability and weight of the cutting deck affect longevity and performance. The PowerSmart mower uses a steel deck. Steel is known for its strength and resistance to impacts, which can help the mower last longer in rugged conditions. The WORX mower deck utilizes AERODECK TECHNOLOGY, a vented design that boosts air volume. This engineering helps prevent clogs and clumping while enhancing cut quality. While the specific material of the WORX deck is not explicitly stated as steel, the focus is on airflow optimization. The PowerSmart offers a traditional, robust steel construction.
Height Adjustment
Adjustable cutting heights allow you to tailor the cut to your grass type and season. The PowerSmart mower offers five height positions, ranging from 1.5 inches to 3.9 inches. This range covers most standard lawn needs. The WORX mower provides seven height positions, extending from 1.5 inches to 4.0 inches. The extra position and the slightly higher maximum cut give you more flexibility. The WORX also uses a single lever for quick changes. This finer control and higher maximum setting make it slightly more adaptable for varying grass conditions.
Which mower fits your yard size
Small yard owner with thick grass
The PowerSmart 18-inch steel deck handles thick grass efficiently via side discharge. Its 144cc gas engine offers consistent power without runtime limits. The 5-position height adjustment lets you set the cut between 1.5 and 3.9 inches for different grass types. This model is ideal for small yards where you need reliable, uninterrupted mowing.
User with half-acre lawn needing mulch
The WORX 21-inch mower covers more ground per pass. Its brushless motor provides 40% more power and includes two 5.0Ah batteries for extended runtime. IntelliCut technology adjusts speed to conserve energy in thin grass. The 3-in-1 design allows mulching, bagging, or rear discharge, making it versatile for larger lawns up to half an acre.
Buyer wanting single-lever height adjustment
The WORX model features a single lever to change cutting heights from 1.5 to 4 inches across seven positions. This simplifies adjustments compared to individual pin settings. The onboard charge indicator helps you monitor battery life. The collapsible handle aids in vertical storage. These specs make height changes and maintenance straightforward for users who value ease of use.

Frequently asked questions
Which mower is lighter to push?
The WORX model is lighter at 55.6 pounds, compared to the PowerSmart’s 58.4 pounds. You will notice the difference when maneuvering around obstacles or storing the unit. Both are push mowers, so you provide all the propulsion. The slight weight advantage of the WORX may reduce fatigue during longer mowing sessions on flat terrain.
How wide is the cutting deck on each?
The WORX mower features a 21-inch cutting width, while the PowerSmart has an 18-inch deck. A wider deck means you cover more ground with each pass. This makes the WORX more efficient for larger areas like half-acre lawns. The PowerSmart’s narrower cut suits smaller, tighter yards where precision matters more than speed.
Does the PowerSmart mower have a bagging option?
No, the PowerSmart 18-Inch model is designed for side discharge only. It does not include bagging or mulching capabilities in its listed functions. You will need to rake or blow clippings after mowing. The WORX offers a 3-in-1 function, allowing you to choose between side discharge, mulching, or bagging based on your preference.
What is the battery capacity for the WORX mower?
The WORX 21-Inch mower uses a 5.0 Ah battery capacity. This is paired with a 40V power source for cordless operation. The capacity helps determine runtime for thicker grass on half-acre lots. If you already own WORX tools, you can use existing batteries, adding convenience and reducing the need for extra purchases.
Can I adjust the cutting height on both mowers?
Yes, both mowers offer height adjustments. The PowerSmart provides five height settings to suit different grass conditions. The WORX also allows height customization, though the exact number of positions is not specified in its data. Adjusting height helps maintain lawn health by ensuring you do not cut too much grass at once.
Which mower is better for thick grass?
The WORX 21-Inch model is rated for half-acre lawns with thick grass. Its intelligent speed adjustment helps maintain consistent cutting power in dense vegetation. The PowerSmart’s 144cc gas engine also handles thick grass well via side discharge. However, the WORX’s electric design and wider deck may offer better performance for larger, overgrown areas.
What are the dimensions of the WORX mower?
The WORX mower measures 60 inches in length, 40.9 inches in height, and 22 inches in width. These dimensions affect storage space and maneuverability. The longer length may make it harder to fit in tight garages. The PowerSmart is more compact at 27.2 inches long, making it easier to store in smaller spaces.
