Having spent several weeks utilizing the PowerSmart 21″ Push Lawn Mower, equipped with the Briggs & Stratton 125cc engine, I’m ready to provide a detailed, technical review for those seeking a thorough understanding of its performance and features. This review aims to go beyond surface-level observations, delving into the nuances of its engine, cutting system, ergonomics, and overall build.
Engine Performance & Efficiency
The heart of this mower is the Briggs & Stratton 125cc, 4-stroke, OHV (Overhead Valve) engine. This configuration is standard for many residential lawnmowers, offering a balance of power and fuel efficiency. The OHV design, in particular, contributes to smoother operation and reduced emissions compared to side-valve engines.
Starting: Initial startup required a few pulls, as is typical for a new engine. However, subsequent starts were consistently within one to two pulls, even after extended periods of inactivity. This indicates a well-tuned carburetor and efficient ignition system.
Power Output: The 125cc engine provided adequate power for cutting through medium-thickness grass. However, when faced with dense, damp grass or taller weeds, a noticeable reduction in RPMs occurred. While the engine didn’t stall, it required a slower pace to maintain a clean cut. The engine’s governor did a reasonable job of regulating RPMs, but its limitations were evident in challenging conditions.
Fuel Consumption: Fuel consumption was relatively efficient, with a full tank providing approximately 1.5 to 2 hours of runtime under typical operating conditions. This is consistent with other small gas engines in this class.
Noise Level: As expected, the engine produced a significant amount of noise. Using ear protection is highly recommended. The noise level is comparable to other gas-powered mowers in this price range.
Cutting System & Performance
The 21-inch cutting deck and blade system offer a decent cutting width for residential lawns. The 2-in-1 functionality (mulching and side discharge) provides flexibility for different lawn care needs.
Cutting Height Adjustment: The 6-position height adjustment, ranging from 1.5 to 3.9 inches, is easily adjustable via a lever on the wheel axle. The adjustment mechanism is robust and holds its position securely.
Cutting Quality: The blade provided a clean and even cut in most conditions. However, the mulching performance was somewhat inconsistent. In dry conditions, the mulching feature produced fine clippings, but in damp or thick grass, clumping occurred. The side discharge function effectively threw clippings several feet away, preventing buildup under the deck.
Blade Design: The blade appears to be a standard single-edge design. An upgrade to a more aggressive mulching blade could potentially improve the mulching performance.
Deck Design: The steel deck is reasonably durable, but it’s relatively thin compared to higher-end models. This could potentially impact its longevity in harsh conditions.
Ergonomics & Maneuverability
The mower‘s lightweight design (62 lbs) contributes to its maneuverability, but some ergonomic aspects could be improved.
Handle Design: The handle is adequately sized and provides a comfortable grip. However, it lacks any vibration dampening, which can lead to fatigue during prolonged use.
Wheel Performance: The wheels are made of durable plastic with rubber treads, providing adequate traction on most surfaces. However, on uneven terrain, the smaller front wheels can struggle to maintain stability. Larger rear wheels help with general maneuverability.
Push Effort: The mower is relatively easy to push on flat terrain. However, hills and inclines significantly increase the effort required. The lack of self-propulsion is noticeable in these situations.
Assembly & Maintenance
Assembly was straightforward, thanks to the clear and concise instruction manual. The process took approximately 45 minutes, requiring basic tools like wrenches and screwdrivers.
Maintenance Access: Access to maintenance points (oil drain, air filter) is relatively easy. The engine’s design simplifies routine maintenance tasks.
Oil Changes: Oil changes are simple, because of the easy access to the oil drain plug.
Air Filter: The air filter is easily accessible, and simple to clean.
Build Quality & Durability
The mower‘s overall build quality is adequate for its price range. However, some components feel less robust than those found in higher-end models.
Deck Material: The steel deck is reasonably durable, but as previously stated, it’s relatively thin.
Wheel Adjusters: The wheel adjusters are made of plastic, which could be a potential weak point.
Handle Brackets: The handle brackets are made of thin steel, which could be prone to bending under stress.
Safety Features
The mower includes standard safety features, such as a start/stop control lever and safety shields.
Start/Stop Lever: The start/stop lever is responsive and easy to engage and disengage.
Safety Shields: The safety shields effectively prevent debris from being thrown towards the user.
Safety Instructions: The included safety instructions are clear and easy to understand.
Overall Assessment:
The PowerSmart 21″ Push Lawn Mower offers a decent balance of performance and affordability for residential use. The Briggs & Stratton 125cc engine provides adequate power for most lawn care needs, and the 2-in-1 cutting system offers flexibility. However, the mower‘s limitations become apparent in challenging conditions, such as thick or damp grass.

FAQs
What type of engine does the PowerSmart 21″ Push Lawn Mower have, and what are its benefits?
The PowerSmart 21″ Push Lawn Mower is equipped with a Briggs & Stratton (B&S) 125cc, 4-stroke, OHV (Overhead Valve) engine. This engine is known for its reliability and efficiency. The OHV design contributes to smoother operation, reduced emissions, and improved fuel economy compared to side-valve engines. It’s a common and trusted engine type in residential lawnmowers, making it easy to find replacement parts and perform maintenance.
Can I mulch and side discharge with this mower, and how easy is it to switch between modes?
Yes, the PowerSmart 21″ Push Lawn Mower offers a 2-in-1 cutting system, allowing you to both mulch and side discharge. Switching between modes is typically straightforward, often involving attaching or detaching a side discharge chute and/or inserting a mulching plug. This flexibility lets you adapt to different lawn conditions and preferences. Mulching finely cuts grass clippings and returns them to the lawn as fertilizer, while side discharge disperses clippings away from the mower.
How difficult is the assembly and maintenance of this lawnmower?
The PowerSmart 21″ Push Lawn Mower is designed for easy assembly, with clear and concise instructions provided in the manual. Most users can assemble it within 30 minutes to an hour using basic tools. Routine maintenance is also relatively simple.

Regular oil changes, air filter cleaning, and blade sharpening are essential for optimal performance and longevity.
Is this lawnmower suitable for all yard sizes and terrains?
The PowerSmart 21″ Push Lawn Mower is best suited for small to medium-sized yards with relatively flat terrain. Its 21-inch cutting width offers a good balance of maneuverability and cutting efficiency. While the lightweight design makes it easy to push, it lacks self-propulsion, which can make it challenging on steep hills or uneven surfaces. For larger yards or those with significant slopes, a self-propelled model might be a better choice.
Final Thought
The PowerSmart 21″ Push Lawn Mower is a solid entry-level gas mower that offers good value for its price. While it has some limitations, it’s a reliable and functional option for typical residential lawn care.
