Overview of the Greenworks Lawn Mowers

The Greenworks 40V 17" Cordless Lawn Mower and the Greenworks 48V (24V x 2) 17" Cordless Push Lawn Mower are both excellent choices for homeowners looking for efficient lawn care solutions. The former is priced at $279.99, while the latter is slightly cheaper at $274.91, making it about 2% less expensive. Both models feature a 17-inch cutting deck and offer versatile mulching and bagging options, catering to different preferences in lawn maintenance.

Performance and Runtime

The Greenworks 40V model provides up to 35 minutes of runtime on a single charge with its 4.0Ah battery, which is included. In comparison, the Greenworks 48V model boasts a longer runtime of up to 45 minutes with two fully charged 4.0Ah batteries. This notable difference of 10 minutes can be crucial for larger yards or tougher mowing conditions. As a result, if extended runtime is a priority, the Greenworks 48V may be the more suitable option.

Cutting Versatility

Both mowers offer versatile cutting options, but they differ slightly in their height adjustment capabilities. The Greenworks 40V features six cutting heights, allowing for precise adjustments based on grass type and conditions. Meanwhile, the Greenworks 48V provides a single lever with five-position height adjustments. While both models effectively handle a variety of grass types, the additional height setting on the 40V model provides slightly more flexibility for achieving the desired cut.

Build and Design

In terms of design, the Greenworks 40V has a durable steel deck that is built for longevity, while the Greenworks 48V features a lightweight, rust-resistant poly deck. The steel deck of the 40V model may contribute to its durability over time, but the lightweight design of the 48V model enhances maneuverability, making it easier to handle for longer mowing sessions. The choice between durability and ease of use may influence buyer preference.

Maintenance and Care

Both lawn mowers are designed to be virtually maintenance-free, eliminating the need for gas or oil. The Greenworks 40V is touted for being 30% quieter than gas mowers and has zero maintenance requirements, including no oil changes. Similarly, the Greenworks 48V emphasizes the absence of emissions and gas-like performance with quiet operation. This feature is a significant advantage for environmentally conscious consumers and those who prefer low-maintenance equipment.

Battery and Charging

The Greenworks 40V comes with one 4.0Ah battery and a charger, while the Greenworks 48V includes two 4.0Ah batteries and a dual-port rapid charger. This means that the 48V model not only offers a longer runtime but also allows for more efficient charging and usage, as one battery can charge while the other is in use. The inclusion of two batteries makes the 48V model particularly appealing for users who want to reduce downtime between mowing sessions.

Pricing and Value

In terms of pricing, the Greenworks 40V is priced at $279.99, while the Greenworks 48V is available for $274.91, making it about $5 cheaper. Additionally, the 40V model has a bestseller rank of 5110, indicating a higher sales volume compared to the 48V’s rank of 15751. This could suggest a greater consumer preference or satisfaction with the 40V model, despite the 48V's lower price point.

Which should you buy?

When choosing between the Greenworks 40V 17" Cordless Lawn Mower and the Greenworks 48V (24V x 2) 17" Cordless Push Lawn Mower, consider your specific needs. If you prioritize longer runtime and dual battery convenience, the Greenworks 48V is the better option. However, if you value a robust steel deck and additional cutting height versatility, the Greenworks 40V could be the right fit for you. Both models deliver excellent performance and ease of use, ensuring that either choice will serve you well in maintaining a beautiful lawn.
