It features a 170cc 4-cycle OHV engine, which is designed for improved cutting efficiency and ease of starting. This mower also boasts a 3-in-1 design, providing options for mulching, side discharge, and rear bagging. With a sales rank of 9,309, it targets users looking for a self-propelled experience, making it easier to navigate uneven terrains and slopes.
Engine Performance Comparison
When it comes to engine performance, the BILT HARD mower features a more powerful 201cc engine compared to the 170cc engine of the PowerSmart model. This difference provides the BILT HARD mower with better torque and overall cutting power. The 201cc engine not only ensures reliable performance but also caters to larger lawns that may require more power. On the other hand, while the PowerSmart's 170cc engine is adequate for small to medium yards, it may struggle with thicker grass or uneven terrain. The extra 31cc in the BILT HARD translates to a noticeable performance boost, especially in challenging mowing conditions.
Cutting Versatility
Both mowers offer impressive cutting versatility with their 3-in-1 capabilities. The BILT HARD mower allows for mulching, side discharge, and rear bagging, providing users with flexibility depending on their lawn care preferences. It features an adjustable cutting height ranging from 1.2" to 3.75", allowing for customization to meet specific lawn needs. In comparison, the PowerSmart mower also provides three cutting options and has a slightly different height adjustment range from 1.5" to 3.9". While both mowers offer versatility, the BILT HARD's broader height adjustment range may give it an edge for users looking for more precise cutting options.
Ease of Use and Comfort
The BILT HARD mower emphasizes user comfort with its ergonomic design, featuring a foam-wrapped angled grip that helps reduce hand fatigue during prolonged use. Its smooth movement is facilitated by 9.5" rear and 8" front double ball-bearing wheels. This design ensures that mowing is a comfortable and effortless experience. On the other hand, the PowerSmart mower includes a self-propelled rear-wheel-drive system, which enhances traction on slopes and uneven terrain. This feature may appeal to those who prioritize ease of use on challenging landscapes. However, the BILT HARD's design may offer a more comfortable grip for extended mowing sessions.
Build Quality and Durability
In terms of build quality, the BILT HARD mower features a sturdy steel deck designed for durability, ensuring that it can withstand regular use over time. Additionally, its robust construction is complemented by the powerful engine, making it a reliable option for homeowners. Meanwhile, the PowerSmart mower also boasts a durable steel deck, which is rugged and built to last. However, the slightly lower engine power may impact its longevity under demanding mowing conditions. Both models are built to handle regular tasks, but the BILT HARD's stronger engine and overall construction may provide superior durability in the long run.
Storage and Portability
Storage and portability are important considerations for lawn mowers. The PowerSmart mower includes a foldable design that saves about 70% of storage space, making it easier to stow away when not in use. This feature is particularly beneficial for users with limited storage space. In contrast, the BILT HARD mower does not mention any specific space-saving features. While the BILT HARD mower is designed for ease of movement during operation, the PowerSmart's foldable design offers a clear advantage in terms of convenience and compact storage.
Which should you buy?
Choosing between the BILT HARD 21 Inch Lawn Mower and the PowerSmart Self Propelled Lawn Mower ultimately depends on your specific needs. If you prioritize power and cutting versatility, the BILT HARD model with its 201cc engine and wider height adjustment range may be the better option, especially for larger and more challenging lawns. However, if you’re looking for a more budget-friendly choice that is easier to maneuver on slopes, the PowerSmart mower could be the right fit. With a price difference of only $20, both mowers have their strengths, making them worthy contenders in the lawn mower category.
