Design and Build Quality

The RB 9" Small Lawn Mower for Small Spaces is ultra-light and compact, weighing only 11.5 lbs without the battery, making it easy to maneuver in tight corners. In contrast, the Wild Badger Power 40V 18″ Cordless Lawn Mower weighs approximately 37.5 lbs, offering a sturdier build but less portability. While the RB mower is designed specifically for small lawns up to 540 sq.ft., the Wild Badger mower can handle larger areas, mowing up to 5,445 sq.ft. This means that while both are useful, their design aims cater to different lawn sizes and user preferences.

Power and Performance

The RB lawn mower features a high-speed 6000 RPM brushless motor, which is efficient for small spaces but may struggle with thicker grass. Meanwhile, the Wild Badger mower boasts a powerful 40V brushless motor that delivers up to 3,400 RPM, allowing it to cut through thicker and taller grass more effectively. This difference in power can make a significant impact on performance, especially for users with more challenging lawn conditions. The RB mower is ideal for light tasks, while the Wild Badger mower is built for a broader range of grass types and conditions.

Battery Life and Charging

The RB mower comes with a 40V 2Ah battery, while the Wild Badger includes a larger 40V 4.0Ah battery. This means the Wild Badger can mow up to 5,445 sq.ft. on a single charge, whereas the RB model is limited to smaller lawns. Additionally, the Wild Badger's battery can be fully charged in about 1.9 hours, ensuring quicker turnaround times for larger lawns. The RB mower's runtime specifics are not provided, but its smaller battery may also imply shorter operational times compared to the Wild Badger.

Cutting Efficiency

The RB mower offers three cutting heights ranging from 1.2" to 2", allowing users to customize their mowing experience for small yards. In comparison, the Wild Badger mower features a five-position height adjustment from 1.5" to 3.5", providing more versatility for different lawn conditions. This added flexibility can be particularly beneficial during varying seasonal conditions, making the Wild Badger a superior option for maintaining a healthy lawn throughout the year.

Safety Features

Safety is paramount in both mowers, but they approach it differently. The RB mower automatically stops if tilted beyond a certain angle, adhering to safety standards. The Wild Badger mower, while not explicitly detailing its safety features, is engineered for residential use, suggesting built-in safety elements like a push-button electric start that eliminates the hassle of cords or pull-starting. The reliability of both mowers in terms of safety will appeal to different segments of users, especially beginners.

Storage and Portability

The RB mower is designed for easy storage with its detachable aluminum handle and upright storage capability, saving up to 70% of space. This compact design is particularly beneficial for users with limited storage options. Conversely, the Wild Badger mower also claims to be easy to store with a folding handle that allows it to slide into compact spaces. However, being heavier, it may not be as portable as the RB mower. Therefore, the choice will depend on individual storage needs and preferences.

Price Comparison

The RB 9" Small Lawn Mower is priced at $169.99, making it about 22% cheaper than the Wild Badger Power mower, which retails at $219.00. This price difference may appeal to budget-conscious consumers who need a reliable mower for small spaces without overspending. However, the additional features and capacity of the Wild Badger might justify its higher price for consumers with larger lawns or specific cutting requirements.

Which should you buy?

Choosing between the RB 9" Small Lawn Mower and the Wild Badger Power 40V 18″ Cordless Lawn Mower ultimately depends on your specific needs. If you have a small lawn and are looking for a lightweight, budget-friendly option, the RB mower excels in maneuverability and ease of storage. However, for users with medium-sized lawns or those needing a more robust cutting capability, the Wild Badger mower offers superior power, battery life, and cutting efficiency, making it worth the extra investment.
