After several weeks of rigorous testing, I’m ready to provide an in-depth, technical review of the PowerSmart 21″ B&S Engine 140cc Self-Propelled Lawn Mower. This machine, boasting a Briggs & Stratton EX550 engine, a durable steel deck, 6-height adjustments, and 3-in-1 mulching versatility, promises a lot. Let’s dissect its performance, features, and overall value.
Engine Performance and Starting Mechanism
The heart of this mower is the Briggs & Stratton EX550, a 140cc engine known for its reliability and power. Starting this engine is generally straightforward, whether it be via the recoil start or the push button start depending on the specific model. The auto choke system is a notable feature, eliminating the need for manual choking in most conditions. During testing, the engine consistently started on the first or second pull (or push of the button), even after periods of inactivity.
The engine’s power delivery is adequate for most residential lawn care tasks. It handles average to moderately thick grass without significant bogging down. However, when faced with extremely dense or overgrown areas, the engine does show signs of strain, requiring a slower mowing pace. Fuel efficiency is reasonable, considering the engine’s power output. A full tank provides ample runtime for a typical suburban lawn.
Self-Propelled System and Maneuverability
The self-propelled system is a significant asset, especially for larger lawns or those with inclines. The rear-wheel-drive system provides good traction on most terrains. However, I did notice that the self-propelled speed can be quite fast, requiring some getting used to. On steeper slopes, the system provides assistance, but some manual pushing is still necessary.
Maneuverability is generally good, but the mower’s size and weight can be factors in tight spaces. The 21-inch cutting deck, while providing efficient coverage, can make navigating narrow passages challenging. The wheels are adequately sized and provide decent traction, but they can struggle in excessively muddy conditions.
Cutting Deck and Height Adjustments
The 21-inch cutting deck is constructed from heavy-duty alloy steel, which feels robust and durable. It withstands impacts from small debris without showing significant damage. The deck’s design promotes good airflow, contributing to efficient bagging and mulching.
The 6-height adjustment system provides versatility for various grass lengths. The adjustment mechanism is relatively easy to use, though some force is required to move the levers. The cutting height range is adequate for most lawn care needs, allowing for both low and high cuts. The deck consistently provides an even cut across the lawn, minimizing scalping.
3-in-1 Functionality: Bagging, Mulching, and Rear Discharge
The 3-in-1 functionality is a key selling point. The bagging system efficiently collects grass clippings, leaving a clean finish. The grass bag is reasonably sized and easy to detach and empty. However, when full, it can become quite heavy.
The mulching function effectively chops clippings into fine pieces, returning nutrients to the soil. After several weeks of consistent mulching, I noticed a visible improvement in lawn health. The rear discharge function is useful for quickly dispersing clippings over a wider area, especially when dealing with longer grass. Switching between these modes is relatively straightforward, though consulting the manual is recommended for first-time users.
Build Quality and Durability
The overall build quality of the PowerSmart mower is commendable. The steel deck, robust engine, and sturdy frame contribute to its durability. After several weeks of use, there are no signs of significant wear and tear. However, like any machine, regular maintenance is crucial for longevity.
The controls are generally user-friendly, though the handle grip could be more ergonomic for extended use. Storage is a consideration, as gas-powered mowers tend to be bulky. The folding handle helps, but it still requires a decent amount of space.
Noise and Vibration
As with any gas-powered mower, noise is a factor. The Briggs & Stratton engine produces typical gas mower noise levels, requiring ear protection for prolonged use. Vibration is also noticeable, but not excessively so. The mower’s design minimizes vibration to a reasonable degree.
Maintenance and Cleaning
Regular maintenance is essential for optimal performance. This includes oil changes, air filter cleaning, and blade sharpening. Cleaning the underside of the cutting deck can be a bit challenging, but it’s necessary to prevent buildup and ensure efficient cutting.
Value and Recommendations
The PowerSmart 21″ B&S Engine 140cc Self-Propelled Lawn Mower offers excellent value for its price. It provides reliable performance, versatile functionality, and durable construction. It’s a suitable option for homeowners with medium to large-sized lawns who prioritize affordability and performance.
