When you compare the greenworks 40v 12 in string vs 24v 15 in cordless, you are looking at two distinct approaches to yard maintenance. Both tools run on battery power and use string trimmer heads for clearing vegetation. The main difference lies in their power systems and intended scope. The 40V model offers a combo kit with a blower, while the 24V model focuses on a single, high-capacity trimmer unit. Your choice depends on whether you need multi-tool versatility or extended runtime for a single task.

Which one should you choose?
Choose Greenworks 40V 12-Inch Trimmer and Blower Combo if
- You want to clear walkways and driveways with a matching blower included in the package.
- You prefer a lighter 8 lb design for extended use around flower beds and patios.
- You already own other Greenworks 40V tools and want to share a single battery type.
Choose Greenworks 24V 15-Inch String Trimmer with 6.0Ah Battery if
- You need a wider 15 in cutting path to cover larger grassy areas more efficiently.
- You require a brushless motor for better durability and longer runtime per charge.
- You want a larger 6.0 Ah battery to handle more extensive trimming jobs without frequent recharging.
Verdict: The 40V combo kit suits those who need a blower for hardscapes and value system compatibility. The 24V trimmer is better for users prioritizing a wider cut, brushless efficiency, and longer battery life for a single tool.
Voltage and Cutting Width Comparison
Voltage and Power System
The Greenworks 40V 12-Inch Trimmer and Blower Combo operates on a 40V platform. This higher voltage system is designed to deliver more power for demanding tasks, such as clearing thick brush along fences or garden borders. In contrast, the Greenworks 24V 15-Inch String Trimmer uses a 24V system. While 24V is sufficient for general yard maintenance, it typically offers less raw power than 40V models. You should choose the 40V option if you frequently encounter dense vegetation. The 24V model is better suited for lighter, routine trimming jobs around plants and shrubs.
Cutting Width and Coverage
Cutting width determines how much area you cover with each pass. The Greenworks 24V model features a 15-inch cutting swath, which is wider than the 12-inch swath on the Greenworks 40V combo. A wider cutting path means you can clear larger areas faster, making the 24V trimmer more efficient for open lawns or extensive grassy patches. The 40V trimmer’s 12-inch width is narrower, which may require more passes to cover the same ground. If your priority is speed and coverage over large surfaces, the 24V model has a clear advantage here.
Battery Capacity and Runtime
Battery capacity directly impacts how long you can work before recharging. The Greenworks 24V trimmer includes a 6.0Ah battery, providing extended runtime for more extensive trimming jobs. This higher capacity allows for longer continuous use without frequent interruptions. The Greenworks 40V combo comes with a 2.0Ah battery. While this battery charges in 60 minutes, its lower capacity means it will deplete faster during heavy use. For tasks that require sustained operation, the 6.0Ah battery in the 24V model offers significantly longer working time per charge.
Motor Type and Efficiency
The motor type influences performance and durability. The Greenworks 24V trimmer is equipped with a brushless motor. Brushless motors are generally more efficient, generate less heat, and require less maintenance than brushed motors. They also offer better speed control via a variable speed trigger. The Greenworks 40V combo does not explicitly list a brushless motor in its key specs, implying it may use a brushed design. For users who value efficiency and precise control over cutting speed, the brushless motor in the 24V model is the superior choice.
Versatility and Tool Ecosystem
The Greenworks 40V combo includes both a string trimmer and a blower, offering immediate versatility for clearing edges and blowing debris. It is part of a 40V ecosystem that supports over eight tools. The Greenworks 24V trimmer is a single tool but is part of a larger 24V ecosystem powering over 200 tools. If you need both trimming and blowing capabilities right now, the 40V combo is more practical. However, if you already own 24V tools or plan to expand your collection with a wider variety of equipment, the 24V platform offers greater long-term compatibility.
Which Greenworks Trimmer Suits Your Needs
Users needing a blower and trimmer combo
This 40V model includes a 390 CFM blower alongside the 12-inch trimmer. You get a complete cleanup system for walkways and driveways. The auto-feed line system handles thick weeds up to one inch. The 40V platform supports over eight tools, allowing you to swap batteries across your entire ecosystem for maximum versatility.
Those prioritizing a wider cutting swath
The 24V trimmer offers a 15-inch cutting path, which is wider than the 12-inch option. It uses a brushless motor for efficiency and a 6.0Ah battery for extended runtime. The bump feed system keeps line ready while you work. This setup is ideal for covering larger areas quickly with less frequent stops to reload the string.
Buyers wanting a single lightweight trimmer
You get a dedicated string trimmer without the added bulk of a blower attachment. The 24V system is lighter and easier to maneuver around plants. The variable speed trigger gives you precise control over cutting speed. The included 6.0Ah battery provides long runtime, and the USB-C charger can also power your other electronic devices.
