Updated July 2026 — full head-to-head comparison.
Price Comparison
The LawnMaster Electric Lawn Mower is priced at $134.99, making it about 17% cheaper than the RB 9" Small Lawn Mower, which costs $169.99. This price difference could appeal to budget-conscious consumers looking for an efficient lawn mower without breaking the bank. While both mowers offer distinct features suited for different lawn sizes, the lower price of the LawnMaster may attract those who want a reliable mower for larger areas without incurring higher costs.
Cutting Width and Efficiency
The LawnMaster features a 19-inch cutting width, which is significantly larger than the RB’s 9-inch cutting width. This larger size allows for quicker mowing of larger lawns, making the LawnMaster more efficient for homeowners with bigger spaces. With its powerful 12AMP motor running at 3600 RPM, the LawnMaster is designed for high efficiency. In contrast, the RB mower is equipped with a brushless motor that operates at 6000 RPM, but its reduced cutting width limits its effectiveness for larger yards, focusing instead on small, tight spaces.
Maneuverability
The RB 9" Small Lawn Mower excels in maneuverability due to its ultra-light weight of only 11.5 pounds without the battery. This feature makes it ideal for navigating tight corners and small areas, which is further enhanced by its one-hand steering capability. Conversely, while the LawnMaster weighs 35 pounds and is designed for ease of use with its 6.7-inch wheels, it may not be as agile in small, confined spaces. Therefore, for users with smaller lawns, the RB mower's design is advantageous.
Cutting Heights
The LawnMaster offers six cutting positions ranging from 1.5 inches to 4 inches, providing users with a variety of options to achieve their desired lawn height. This feature allows for more customization compared to the RB mower, which has three adjustable cutting heights from 1.2 inches to 2 inches. The broader range of cutting heights in the LawnMaster makes it suitable for various grass types and growth conditions, giving it an edge for those who value flexibility.
Safety Features
Safety is a critical consideration for lawn mowers, and both models incorporate safety features. The RB mower includes an advanced safety design that automatically stops the motor if tilted beyond 20° to 70°, aligning with US safety standards. On the other hand, while the LawnMaster does not specify safety features in the provided data, its construction and design are likely to meet general safety expectations. For users concerned about safety, the RB mower's explicit safety feature may be a deciding factor.
Storage Options
In terms of storage, the RB 9" Small Lawn Mower offers a space-saving design with a detachable aluminum handle and the ability to store upright, saving up to 70% of space. This compact design makes it an excellent choice for users with limited storage areas. The LawnMaster, while effective, does not highlight any specific storage features, which could make it less convenient for those needing to conserve space in their garages or sheds.
Target Audience
The LawnMaster is best suited for homeowners with medium to large lawns, thanks to its broader cutting width and powerful motor. Its efficiency makes it a solid choice for those who want to tackle larger areas quickly. Conversely, the RB 9" Small Lawn Mower is tailored specifically for users with small lawns or those who struggle with traditional mowers. Its lightweight design and easy maneuverability make it an excellent option for beginners or those looking for a simple, no-fuss mowing experience.
Which should you buy?
Deciding between the LawnMaster Electric Lawn Mower and the RB 9" Small Lawn Mower largely depends on your specific lawn care needs. If you have a larger yard and prefer a mower that offers efficiency and a wider cutting width at a lower price, the LawnMaster is the better choice at $134.99. However, if your focus is on maneuverability, safety, and a lightweight design for small spaces, the RB model priced at $169.99 may be more suitable. Ultimately, your choice should reflect the size and layout of your lawn along with your personal preferences for mowing ease and storage.
