Overview of the Lawn Mowers
When comparing the RB 9" Small Lawn Mower for Small Spaces and the SKIL PWR CORE 40 Brushless 40V 20-Inch Self-Propelled Mower Kit, it's clear that each has its unique strengths suited for different users. The RB mower is designed for small yards, while the SKIL model caters to larger lawns with its self-propelling feature and extended runtime. The price difference is significant, with the RB mower retailing at $169.99 and the SKIL model priced at $349.00, making the RB mower about 51% cheaper.
Design and Maneuverability
The RB 9" Small Lawn Mower is ultra-light and compact, weighing only 11.5 lbs without the battery. This lightweight design allows for easy maneuverability in tight spaces, which is ideal for small yards up to 540 sq. ft. Its one-hand steering and pivoting front wheels enhance usability, enabling users to navigate corners effortlessly. In contrast, the SKIL mower, while larger with a 20-inch cutting deck, also has a foldable handle for convenient storage. However, it weighs more, which can make it less maneuverable in confined areas.
Performance and Power
In terms of power, the RB mower features a high-speed 6000RPM brushless motor, enabling efficient mulching without maintenance. This model is perfect for maintaining smaller lawns but may struggle with tougher grass types. The SKIL mower boasts a digital brushless motor that provides efficient, high-performance power without the hassle of gas, making it suitable for larger areas. It includes a 6.0Ah battery for up to 50 minutes of runtime, allowing for longer mowing sessions compared to the RB’s smaller 2Ah battery.
Cutting Capability
The RB mower offers three adjustable cutting heights from 1.2" to 2", perfect for maintaining short grass. This range allows for a tailored approach to lawn care, ideal for users who want to keep their grass looking pristine. On the other hand, the SKIL mower provides a more extensive height adjustment with seven settings from 1.5" to 4". This flexibility is beneficial for varying grass types and user preferences, making it a more versatile option for those with diverse lawn care needs.
Safety Features
Safety is a notable aspect of both mowers, though they approach it differently. The RB mower automatically stops if tilted beyond 20°–70°, ensuring safety during operation, especially for beginners. This feature meets US safety standards, providing peace of mind. The SKIL mower, while not highlighting specific safety features in its description, includes a push-button start for added convenience, which simplifies operation and may reduce the risk of accidents associated with traditional starting methods.
Storage Options
Storage is an essential consideration, especially for those with limited space. The RB mower’s detachable aluminum handle and upright storage capability allow it to save up to 70% of storage space. This compact design is particularly advantageous for users with small storage areas. In contrast, the SKIL mower's telescoping handle also allows for vertical storage, but it doesn’t emphasize a significant space-saving aspect, making the RB mower a better choice for compact living situations.
Battery and Charging
Battery life and charging speed are crucial factors when selecting a cordless mower. The RB mower comes with a 40V 2Ah battery suitable for small tasks but may require more frequent charging for larger jobs. The SKIL mower, however, includes a 6.0Ah battery, allowing for up to 50 minutes of runtime on a single charge. Additionally, it features an Auto PWR JUMP charger, which can quickly charge the battery, making it more suitable for users who need to cover larger areas without waiting long periods for a recharge.
Which should you buy?
Choosing between the RB 9" Small Lawn Mower and the SKIL PWR CORE 40 Brushless Mower ultimately depends on your specific lawn care needs. If you have a small yard and prioritize a lightweight, compact design with a lower price point, the RB mower at $169.99 is an excellent choice. However, for those with larger lawns requiring more power, runtime, and versatility, the SKIL mower, despite its higher price of $349.00, offers features that justify the investment. Each mower excels in its category, making them suitable for different types of users.
