40V vs 24V Key Specs Compared
Voltage and Power
The Greenworks 40V 13-Inch Cordless String Trimmer operates at 40 volts, while the Greenworks 24V 12" String Trimmer & Blower Combo runs on 24 volts. Higher voltage generally translates to more power for demanding tasks. The 40V model is designed for heavier-duty trimming, whereas the 24V system is part of a broader ecosystem focused on lighter maintenance. Both systems utilize a 2.0 Ah battery capacity, ensuring consistent runtime across the brand's compatible tools. You should choose the voltage that matches the intensity of your yard work.
Cutting Width
Cutting swath determines how much ground you cover in a single pass. The Greenworks 40V 13-Inch Cordless String Trimmer features a 13-inch cutting width. In comparison, the Greenworks 24V 12" String Trimmer & Blower Combo offers a 12-inch cutting path. The extra inch on the 40V model may help you clear weeds and overgrowth slightly faster. This difference is small but noticeable when maintaining larger areas. If you have dense vegetation, the wider swath provides a minor efficiency advantage.
Motor Type
The Greenworks 24V 12" String Trimmer & Blower Combo explicitly lists a brushless motor for the trimmer component. Brushless motors are typically more efficient, durable, and require less maintenance than brushed alternatives. The product data for the Greenworks 40V 13-Inch Cordless String Trimmer does not specify the motor type. Without this information, you cannot confirm if it uses a brushless design. The 24V model’s stated brushless technology suggests potentially longer motor life and better power management.
Line Feed System
How the trimmer line advances affects your workflow. The Greenworks 24V 12" String Trimmer & Blower Combo includes an auto-feed system. This feature ensures continuous line feed, eliminating the need for manual adjustments during use. The Greenworks 40V 13-Inch Cordless String Trimmer description mentions an auto-line that handles 1.5-inch weeds, but it does not explicitly label the feed mechanism as auto-feed. The 24V model’s dedicated auto-feed system offers a clear convenience advantage for uninterrupted trimming sessions.
Versatility and Accessories
The Greenworks 24V 12" String Trimmer & Blower Combo is sold as a kit that includes a 270 CFM blower. This provides immediate value for clearing leaves and debris alongside trimming. The Greenworks 40V 13-Inch Cordless String Trimmer is a single tool. However, the 40V model includes a steel edging guide and a telescoping shaft with a 7-position handle, allowing for precise edging and height adjustments. The 24V combo offers tool variety, while the 40V tool offers specialized trimming features.
Which Greenworks String Trimmer Fits Your Yard
Users with tall frames needing adjustable reach
The 40V model features a telescoping shaft that adjusts from 40 to 52 inches. This range accommodates users between 5 feet 2 inches and 6 feet 4 inches.
