Which one should you choose?
Choose Greenworks 40V 12-Inch Trimmer and Blower Combo if
- You need maximum blower power to move wet leaves or heavy debris from driveways.
- You already own other 40V Greenworks tools and want to share the same battery ecosystem.
- You prefer a higher voltage system for potentially faster cutting in thick weeds.
Choose Greenworks 24V 12" String Trimmer & Blower Combo if
- You want a lighter trimmer to reduce fatigue during extended edging or trimming sessions.
- You prefer brushless motor technology for improved efficiency and longer tool life.
- You value a faster airspeed (130 MPH) for clearing light debris from tight spaces.
Verdict: Choose the 40V combo if your priority is raw blowing power and compatibility with a broader range of high-voltage tools. Select the 24V combo if you prioritize a lighter, more manageable trimmer with efficient brushless motors. Both handle the 12-inch cutting path effectively, so your decision rests on weight and voltage preferences.
40V vs 24V Greenworks Specs
Voltage and Power
The Greenworks 40V 12-Inch Trimmer and Blower Combo operates on a 40V system. This higher voltage platform typically delivers more sustained power for demanding tasks. The Greenworks 24V 12" String Trimmer & Blower Combo uses a 24V system. While both are cordless, the 40V model is designed for heavier brush and thicker weeds. You get more torque with the higher voltage. The 24V option is sufficient for light to medium yard work. If you have dense overgrowth, the 40V system provides a clear advantage in raw power output.
Motor Type
The 24V model features a brushless motor. Brushless motors are generally more efficient, last longer, and require less maintenance than brushed alternatives. The data for the 40V model does not explicitly state the motor type. However, the 24V model highlights its brushless design as a key feature for efficiency. If the 40V model also uses a brushless motor, the difference is neutral. If it uses a brushed motor, the 24V model wins on longevity and efficiency. You should check the specific 40V variant for motor details.
Cutting Width
Both trimmers share the same 12-inch cutting swath. This width is standard for residential string trimmers. It allows you to clear weeds along fences and garden borders efficiently. The 40V model uses a 0.065-inch auto-feed line. The 24V model also uses a 0.065-inch single line with an auto-feed system. Since the cutting width and line feed mechanism are identical, neither product has an advantage here. You get the same coverage area per pass with either tool. The choice depends on power needs rather than cutting width.
Blower Airflow
The 40V combo includes a blower with 390 CFM airflow and 110 MPH airspeed. The 24V combo includes a blower with 270 CFM airflow and 130 MPH airspeed. The 40V model moves more volume of air, which is better for wet leaves and heavy debris. The 24V model has higher airspeed but lower volume. For clearing driveways and patios, the higher CFM of the 40V model is often more effective. You will clear debris faster with the 40V blower due to the greater air volume.
Weight and Balance
The 24V trimmer weighs only 4.08 lbs without the battery. This makes it significantly lighter and easier to handle for extended periods. The 40V combo lists a total weight of 16.5 lbs for the set. The 40V trimmer itself is described as featherweight, but specific trimmer-only weight is not provided in the key specs. The 24V model’s light weight reduces fatigue during use. If you have back issues or prefer a lighter tool, the 24V model is the better choice for comfort and ease of use.
Battery and Charging
Both kits include a 2.0Ah battery. The 40V model charges in approximately 60 minutes. The 24V model includes a 30W USB-C GAN charger. This charger can also power USB-C devices like phones. The 40V model uses the brand’s universal 40V power hub ecosystem. The 24V model is part of the 24V ecosystem. You cannot swap batteries between the 24V and 40V systems. If you already own 40V tools, the 40V combo is more compatible. If you want versatile charging options, the 24V USB-C charger is a unique benefit.
