Spec Comparison: 40V vs 24V Trimmers
Voltage and Power
The Greenworks 40V 13-Inch Cordless String Trimmer operates on a 40V system, providing higher voltage for robust performance. In contrast, the Greenworks 24V 15-Inch String Trimmer uses a 24V platform. Higher voltage typically correlates with increased torque and cutting power, which can help the 40V model handle thicker vegetation more effectively. The 24V system is designed for lighter to moderate tasks, offering sufficient power for standard yard maintenance. You should choose based on the density of the weeds you plan to cut.
Cutting Width
Cutting width determines how much ground you cover per pass. The Greenworks 24V 15-Inch String Trimmer features a 15-inch cutting swath, allowing you to clear larger areas faster with fewer passes. The Greenworks 40V 13-Inch Cordless String Trimmer has a 13-inch cutting path. While the difference is two inches, it adds up over time when trimming large lawns or wide borders. The 24V model offers a slight efficiency advantage for speed, while the 40V model may offer better maneuverability in tighter spaces.
Battery Capacity
Battery capacity directly impacts runtime. The Greenworks 24V 15-Inch String Trimmer includes a 6.0 Ah battery, providing significantly longer operation time per charge compared to the 2.0 Ah battery included with the Greenworks 40V 13-Inch Cordless String Trimmer. If you have a large yard or plan to trim for extended periods, the 6.0 Ah battery reduces the need for frequent recharges. The 2.0 Ah battery is lighter and may be sufficient for smaller jobs, but it will require more frequent swaps or recharging.
Motor Type
The Greenworks 24V 15-Inch String Trimmer is equipped with a brushless motor, which is generally more efficient, durable, and requires less maintenance than brushed motors. The specifications for the Greenworks 40V 13-Inch Cordless String Trimmer do not explicitly state the motor type, though it is a key spec for efficiency. Brushless motors often provide longer tool life and better power delivery. If motor longevity and efficiency are priorities, the 24V model has a clear advantage based on its published specifications.
Weight and Maneuverability
Weight affects user fatigue during extended use. The Greenworks 40V 13-Inch Cordless String Trimmer weighs 9.92 pounds, while the weight of the Greenworks 24V 15-Inch String Trimmer is not listed in the provided data. The 40V model also features a telescoping shaft and adjustable handle, allowing you to customize the length for your height and comfort. This adjustability can reduce strain on your back and arms. Without the weight data for the 24V model, it is difficult to make a definitive comparison, but the 40V model offers verified ergonomic adjustments.
Line Feed System
Line feed systems affect how easily you maintain the trimmer line. The Greenworks 24V 15-Inch String Trimmer includes a bump feed system and a quick load function, allowing you to reload the 0.080-inch dual twisted line in under 60 seconds. This feature enables continuous trimming without stopping to reload. The Greenworks 40V 13-Inch Cordless String Trimmer uses a 0.065-inch auto-line system, which automatically feeds line as you trim. Both systems offer convenience, but the 24V model provides faster manual reloading options for larger diameter line.
Which trimmer fits your yard?
Users with tight spaces and decks
The 40V model features a telescoping shaft that adjusts from 40 to 52 inches, accommodating users between 5'2" and 6'4". Its 13-inch cutting swath is ideal for precision work around fences and flower beds. The pivoting head allows you to switch between trimming under decks and edging sidewalks quickly. This adjustability ensures you can reach difficult spots without straining your back or awkwardly positioning the tool.
Those covering larger lawns efficiently
This 24V trimmer offers a wider 15-inch cutting path, allowing you to clear more grass per pass. It includes a 6.0 Ah battery, which provides extended runtime for extensive jobs without frequent recharges. The brushless motor enhances efficiency, and the bump feed system keeps the line ready for continuous use. If your yard is larger, the broader swath and longer battery life help you finish tasks faster.
Buyers wanting versatile charging options
The 24V model comes with a 65W USB-C charger that powers the trimmer battery and also charges smartphones, laptops, and tablets. This dual-purpose feature adds convenience if you already use USB-C devices. It includes a 6.0 Ah battery for longer operation. While the 40V model focuses on raw power and adjustability, this option integrates better with modern electronics through its versatile charging capability.
