Greenworks 40V 16" Cordless Lawn Mower vs Greenworks 40V 17" Cordless Lawn Mower

Design and build quality

Both models in the Greenworks 40V lineup prioritize user comfort and ergonomic design, aiming to reduce the physical strain associated with lawn maintenance. The Greenworks 40V 16" Cordless Lawn Mower emphasizes an ultra-lightweight design, claiming to be 35% lighter than comparable gas units. This focus on weight reduction makes it particularly suitable for users who prioritize ease of storage and maneuverability around obstacles. The ergonomic handles and push-button start mechanism are designed to make operation effortless without the need for pull cords.

The Greenworks 40V 17" Cordless Lawn Mower also features a lightweight design but distinguishes itself with a 17-inch steel deck. Steel decks are generally associated with higher durability and longevity compared to polymer alternatives, offering better protection against debris impact. While both mowers include grass bags and share a similar aesthetic profile within the Greenworks ecosystem, the 17-inch model’s explicit mention of steel construction suggests a slight edge in long-term build resilience for rougher terrain.

Cutting Deck and Coverage

The primary physical difference between these two units lies in the cutting deck width and the recommended coverage area. The Greenworks 40V 16" Cordless Lawn Mower utilizes a 16-inch cutting deck, which is optimized for small to medium lawns. Despite the slightly narrower cut, the manufacturer rates this model for yards up to 1/3 acre. This efficiency suggests that the battery management and motor power are tuned to maximize the area covered per charge rather than relying solely on deck width.

In contrast, the Greenworks 40V 17" Cordless Lawn Mower features a 17-inch deck, providing a wider swath of cut with each pass. This can reduce the number of passes required to mow a straight line. However, the recommended coverage area is listed as up to 1/4 acre. While the larger deck is beneficial for open spaces, the reduced coverage rating implies that the power consumption may be higher per minute of operation, potentially due to the larger blade mass or motor tuning. Users with compact but dense lawns might prefer the 16-inch model’s efficiency, while those with open spaces might value the 17-inch width.

Performance and Motor

Motor technology is a critical differentiator in cordless outdoor power equipment. The Greenworks 40V 17" Cordless Lawn Mower explicitly features a brushless motor. Brushless motors are known for providing higher torque, longer motor life, and increased efficiency compared to brushed counterparts. This technology typically results in better performance when tackling thick or wet grass, as the motor can adjust power delivery without the friction losses associated with brushes.

The Greenworks 40V 16" Cordless Lawn Mower description focuses on “gas-like performance” but does not explicitly specify the motor type in the provided data. While it delivers sufficient power for standard maintenance, the lack of explicit brushless designation suggests the 17-inch model may have a technical advantage in raw power delivery and longevity. However, both models offer instant push-button start, eliminating the hassle of priming and pulling cords associated with gas engines.

Cutting Height Adjustment

Adjustability is essential for maintaining lawn health across different seasons and grass types. The Greenworks 40V 16" Cordless Lawn Mower employs a single-lever 5-position height control system. This allows users to adjust the cutting height between 1.25 inches and 3.375 inches. This range is sufficient for most common turf grasses, allowing for higher cuts in summer to retain moisture and lower cuts for spring cleanup.

The Greenworks 40V 17" Cordless Lawn Mower offers a 6-position height adjustment system, also operated via a single lever. The additional position provides finer granularity when dialing in the perfect cut height. While the specific range measurements are not provided for the 17-inch model in the data, the extra position offers slightly more versatility for users who are particular about their lawn’s appearance. Both systems are designed for easy adjustment without the need for tools.

Battery life and efficiency

Runtime is often the most critical specification for cordless lawn mowers. The Greenworks 40V 16" Cordless Lawn Mower delivers up to 40 minutes of continuous runtime from a single 4.0Ah battery. It also specifies a full charge time of 2 hours using the included fast charger. This efficiency allows it to cover up to 1/3 acre on a single charge, making it a strong contender for properties where recharging mid-mow is not an option.

The Greenworks 40V 17" Cordless Lawn Mower provides up to 35 minutes of runtime on a single charge with the included 4.0Ah battery. While only 5 minutes less than the 16-inch model, this reduction correlates with the smaller recommended coverage area of 1/4 acre. For users with yards closer to the 1/3 acre mark, the 16-inch model offers a safer margin of battery life. Both models are part of the Greenworks 40V ecosystem, meaning the batteries are interchangeable with over 75 other tools.

Noise and Operation

Noise pollution is a significant concern for suburban homeowners. The Greenworks 40V 16" Cordless Lawn Mower specifies a noise level of less than 75dB. This whisper-quiet operation allows for mowing at times when gas mowers would be disruptive, such as early mornings or evenings. The elimination of gas emissions also contributes to a cleaner operating environment without the smell of fuel or exhaust.

The Greenworks 40V 17" Cordless Lawn Mower claims to be 30% quieter than gas mowers, with some text indicating 50% less noise. While both models offer a significant reduction in noise compared to internal combustion engines, the 16-inch model’s specific decibel rating provides a more concrete metric for comparison. Both units operate without the vibration and maintenance associated with gas engines, ensuring a smoother user experience during operation.

Price and value

Both the Greenworks 40V 16" Cordless Lawn Mower and the Greenworks 40V 17" Cordless Lawn Mower are priced identically at $279.99. This price point includes the tool, a 4.0Ah battery, a fast charger, and a grass bag. Both models also come with a 3-year tool warranty and a 3-year battery warranty, ensuring long-term protection for the investment. The value proposition differs slightly based on needs; the 16-inch model offers better runtime efficiency, while the 17-inch model offers brushless technology and a steel deck.

Considering the identical cost, the value depends on whether the user prioritizes runtime or motor technology. The 16-inch model saves users an estimated $200+ annually compared to gas mowers by eliminating fuel and maintenance costs. The 17-inch model offers similar savings but adds the potential longevity benefits of a brushless motor. Both integrate into the same 40V ecosystem, allowing for future expansion with trimmers, blowers, and chainsaws.

Which one should you buy?

Choosing between these two models depends largely on the specific layout of your yard and your priority between runtime and deck features. If your primary concern is maximizing the area you can mow on a single charge, the Greenworks 40V 16" Cordless Lawn Mower is the superior choice. Its 40-minute runtime and 1/3 acre coverage rating provide greater efficiency, ensuring you can finish the job without worrying about battery depletion. This makes it ideal for irregularly shaped yards where efficiency matters more than raw deck width.

However, if you value motor technology and deck durability, the Greenworks 40V 17" Cordless Lawn Mower is the better option. The brushless motor offers higher torque and potentially longer life, while the steel deck provides added robustness. This model is well-suited for users with open lawn areas up to 1/4 acre who prefer the technical advantages of brushless engineering. Since the price is identical, the decision rests on whether you prioritize the extended runtime of the 16-inch model or the motor and deck specifications of the 17-inch model.
