Verdict: The 40V trimmer suits users with small yards who prioritize lightweight handling and existing 40V ecosystem compatibility.

Choose based on whether you value compact maneuverability or raw cutting performance.
Voltage and Cutting Width Comparison
Voltage and Power
The Greenworks 40V 12-Inch Trimmer and Blower Combo operates on a 40V platform, while the Greenworks 60V 16-Inch Cordless String Trimmer uses a 60V system. Higher voltage typically translates to greater torque and sustained power under load. The 60V model is described as delivering power equivalent to a 26cc gas trimmer, capable of handling thick blackberry vines and stubborn kudzu. The 40V unit focuses on general maintenance, clearing overgrown edges and light weeds. For users with dense vegetation, the increased voltage of the 60V system provides a clear advantage in cutting efficiency and motor stamina.
Cutting Swath Width
Cutting width determines how much ground you cover with each pass. The 40V model features a 12-inch cutting swath, suitable for detailed work along fences and garden borders. In contrast, the 60V model offers a 16-inch professional swath. This four-inch difference allows the 60V trimmer to clear significantly more area per minute, making it ideal for larger properties or long fence lines. The wider deck on the 60V unit reduces the number of passes required to finish a job. If your priority is speed and covering large areas of overgrown ditch weeds, the 60V trimmer provides a distinct operational benefit.
Motor Type
Motor technology impacts efficiency, longevity, and maintenance. The 60V Greenworks trimmer is equipped with a brushless motor that delivers 6000 RPM. Brushless motors generally offer longer lifespans, better energy efficiency, and consistent power delivery compared to brushed alternatives. The specifications for the 40V model do not explicitly state the motor type, though it is part of the same brand ecosystem. The brushless design in the 60V unit supports its higher power output and contributes to its ability to tackle thick vegetation without stalling. This technical specification gives the 60V model an edge in performance reliability.
Battery Capacity
Both tools use rechargeable lithium-ion batteries, but their capacities differ. The 40V combo kit includes a 2.0Ah battery, while the 60V trimmer comes with a 2.5Ah battery. A higher amp-hour rating indicates a larger energy reserve, which can extend runtime between charges. The 60V model is noted to run for up to 1.5 acres on a single charge, outlasting standard cordless trimmers by 20 minutes in testing conditions. The 40V battery charges in 60 minutes, whereas the 60V battery recharges in 45 minutes. The combination of higher capacity and faster charging makes the 60V setup more efficient for extended use.
Line Feed System
How you reload the trimmer line affects convenience during use. The 40V model utilizes an auto-feed system, which releases line automatically as you bump the head against the ground. This is a standard, reliable method for maintaining line length. The 60V model features a spin-to-load head design, allowing you to reload .095-inch line in just 10 seconds by twisting the housing. This system eliminates manual winding and saves time compared to traditional bump feed heads. For users who frequently run through line, the spin-to-load mechanism offers a practical advantage in reducing downtime and frustration during operation.
