Overview of Lawn Mowers

When it comes to choosing a lawn mower, efficiency, ease of use, and price are crucial factors. The Greenworks 40V 16" Cordless Lawn Mower offers a robust performance ideal for larger yards, while the STEELITE 21V 13-Inch Brushless Electric Lawn Mower is designed for smaller spaces and lighter use. Both mowers come with a 4.0Ah battery and charger, but they cater to different lawn care needs.

Price Comparison

The Greenworks mower is priced at $279.99, which places it in the higher-end category of lawn mowers. In contrast, the STEELITE mower is significantly more budget-friendly at $139.99, making it about 50% cheaper than its competitor. This price difference may appeal to users with smaller lawns or those who are cost-conscious but still want a reliable cordless mower.

Runtime and Power

The Greenworks mower provides an impressive 40 minutes of runtime, powered by a 40V battery, which is suitable for lawns up to 1/3 acre. On the other hand, the STEELITE mower offers a shorter runtime of 25 minutes with its 21V battery, making it better suited for small to mid-sized yards. Users who prioritize longer mowing sessions may find the Greenworks mower more suitable for their needs.

Design and Maneuverability

In terms of design, the Greenworks mower features a lightweight build, being 35% lighter than traditional gas mowers, while still providing a 16-inch cutting deck. This design makes it easy to maneuver, especially for users who value comfort and ease of storage. The STEELITE mower is even lighter at just 20.5 lbs and has a compact 13-inch deck, making it easier to lift and navigate through tight spaces, which is ideal for small yards or slopes.

Cutting Height Adjustment

The Greenworks mower offers a smart cut adjustment system with a single-lever height control that allows users to choose from five different cutting heights, ranging from 1.25 inches to 3.375 inches. This versatility is beneficial for accommodating various grass types. In comparison, the STEELITE mower also features a 5-level height adjustment, but it offers a range from 0.98 inches to 2.56 inches. This could limit the options for users who prefer taller grass.

Maintenance and Eco-Friendliness

One of the standout features of the Greenworks mower is its zero maintenance requirement, which means no gas or oil costs, emissions, or engine tune-ups. This translates to annual savings of over $200 compared to gas mowers. The STEELITE mower, while also electric, does not emphasize maintenance savings in the same way. For environmentally-conscious consumers, the Greenworks mower’s eco-friendly operation may be a significant advantage.

Features and Accessories

The Greenworks mower comes with a complete ecosystem value, including a grass bag, fast charger, and a 3-year warranty for both the tool and battery. Additionally, it is compatible with more than 75 other Greenworks 40V tools, allowing users to expand their cordless toolkit easily. The STEELITE mower includes a mulching and bagging option with an 8-gallon grass bag, which is convenient for lawn care but lacks the broader compatibility with additional tools.

Which should you buy?

Ultimately, the decision between the Greenworks 40V 16" Cordless Lawn Mower and the STEELITE 21V 13-Inch Brushless Electric Lawn Mower depends on your specific lawn care needs. If you have a larger yard and are looking for a mower that offers longer runtime, greater cutting height versatility, and lower maintenance, the Greenworks mower is the better choice despite its higher price. Conversely, if you need a lightweight, cost-effective solution for a smaller area, the STEELITE mower provides excellent value and performance.
