Pricing Comparison
Both the American Lawn Mower Company 51319 and the RB 9 Small Lawn Mower are priced identically at $169.99. This parity in pricing makes it easy for consumers to weigh other factors when making a decision. Despite the same price point, the features and capabilities of each mower cater to different lawn care needs. With this in mind, understanding what each product offers can help consumers determine which is the better value for their specific requirements.
Power and Performance
The American Lawn Mower Company 51319 is equipped with a 13-Amp motor, providing robust cutting power suitable for larger lawns. In contrast, the RB 9 Small Lawn Mower features a high-speed 6000RPM brushless motor, specifically designed for small lawns up to 540 square feet. While the American mower excels in cutting performance for broader areas, the RB 9’s efficient motor is tailored for maneuverability in tight spaces, making it ideal for urban or smaller properties. This difference in power suggests that your choice should depend on the size of your lawn.
Cutting Efficiency
In terms of cutting efficiency, the American Lawn Mower Company 51319 offers versatile cutting options with its ability to mulch or rear bag, along with adjustable cutting heights from 1 to 3 inches. This feature allows users to customize their lawn care experience effectively. On the other hand, the RB 9 provides three cutting heights ranging from 1.2 inches to 2 inches, making it suitable for maintaining short grass in compact areas. While the American mower allows for slightly taller cutting options, the RB 9's focus on fine mulching emphasizes its efficiency for smaller yards.
Design and Maneuverability
Maneuverability is a strong suit for both mowers, but they approach it differently. The American Lawn Mower Company 51319, being a corded electric mower, is lightweight and designed for easy navigation in tight spaces, though its cord may limit its range. Conversely, the RB 9 is ultra-lightweight at just 11.5 pounds (excluding the battery), featuring pivoting front wheels and one-hand steering. This design makes it exceptionally easy to handle in confined areas. Therefore, if you have a small yard or tight corners to navigate, the RB 9 may have the upper hand.
Environmental Impact
When considering environmental impact, the American Lawn Mower Company 51319 is an eco-friendly option that eliminates the need for gas, oil, and costly maintenance associated with traditional gas mowers. It operates quietly, reducing noise pollution during use. The RB 9 also champions environmental consciousness with its battery power, which eliminates emissions and offers a maintenance-free experience. Both mowers provide a cleaner alternative to gas-powered models, but the American mower stands out for those who prefer a corded option while still maintaining a minimal environmental footprint.
Safety Features
The RB 9 includes advanced safety features, such as an automatic shut-off if tilted beyond a certain angle, ensuring compliance with US safety standards. This is particularly valuable for novice users or those concerned about safety while mowing. While the American Lawn Mower Company 51319 does not explicitly mention safety features in its specifications, its lightweight design and push operation can also reduce the risk of accidents. The RB 9's focus on safety, however, gives it a distinct advantage for first-time users or those with small children around.
Storage Solutions
Both mowers offer convenient storage options, but the RB 9 excels in this area. It features a detachable aluminum handle and an upright storage design that saves up to 70% of storage space, making it ideal for small homes with limited storage capacity. The American Lawn Mower Company 51319, while compact, does not offer the same level of space-saving design as the RB 9. If storage is a primary concern, the RB 9 is the better choice for urban dwellers or those with smaller garages.
Which should you buy?
Choosing between the American Lawn Mower Company 51319 and the RB 9 Small Lawn Mower ultimately depends on your specific lawn care needs. If you have a larger yard that requires powerful cutting performance and versatility in cutting options, the American mower may be the right fit. However, for those with small spaces seeking a lightweight, maneuverable, and safe lawn care solution, the RB 9 stands out as an excellent choice. Both are priced the same at $169.99, so your decision should hinge on the size of your lawn and your preferred mowing experience.
