80V vs 40V Trimmer Comparison
Voltage and Power
The Greenworks 80V 16-Inch Brushless Trimmer operates at 80 volts, while the Greenworks 40V 16-Inch Brushless String Trimmer runs on 40 volts. Higher voltage typically translates to more torque and sustained power under load. The 80V model is described as delivering strong cutting power to handle tough grass and weeds, making it suitable for demanding yard maintenance and larger lawns. The 40V model is marketed as professional grade and capable of powering through tough yards, but it shares the same 16-inch cutting path. If you have a large property with dense vegetation, the higher voltage of the 80V system may provide a performance advantage. The 40V system is part of a broader ecosystem, but strictly in terms of raw electrical potential, the 80V unit holds the edge.
Weight and Maneuverability
Weight significantly impacts user fatigue during extended trimming sessions. The Greenworks 80V 16-Inch Brushless Trimmer weighs 16 pounds. In contrast, the Greenworks 40V 16-Inch Brushless String Trimmer weighs only 11.3 pounds. The 40V model is explicitly noted as being 25% lighter than comparable gas-powered models, emphasizing its lightweight design for comfort and control. This substantial weight difference of nearly five pounds means you will likely experience less arm and shoulder strain when using the 40V trimmer, especially if you are working around obstacles like flower beds or fence lines. The lighter build of the 40V unit makes it easier to maneuver for detailed edging work. For users prioritizing ease of handling over raw power, the lighter tool is the better choice.
Battery and Runtime
Power source and battery capacity are critical for runtime. The Greenworks 80V 16-Inch Brushless Trimmer includes a 2.0 Ah battery and features rapid charging in just 30 minutes. This allows you to get back to work quickly. The Greenworks 40V 16-Inch Brushless String Trimmer is sold as a tool only, meaning it does not include a battery in the base package. However, it is compatible with over 75 Greenworks 40V tools, offering extensive ecosystem flexibility if you already own other 40V equipment. The 80V model provides an immediate, complete solution with its included battery. If you do not own Greenworks batteries, the 80V kit is more convenient. If you already have 40V batteries, the 40V tool leverages your existing investment.
Line Feed System
Both trimmers utilize a bump feed line advancement system, which allows for quick and easy line extension while trimming without stopping. This feature keeps you productive by letting you tap the head against the ground to feed more line. The Greenworks 80V model uses a .080-inch dual line for efficient trimming and cleaner cuts across wide areas. The Greenworks 40V model uses a slightly thicker .095-inch dual line, which may offer increased durability and cutting power for thicker weeds. Both systems allow for easy wind reloads in seconds. The difference in line thickness is minor but could affect longevity in very thick vegetation. For most residential users, both bump feed systems provide adequate performance and convenience.
Speed Control
Variable speed control allows you to adjust the cutting speed on the go, which is useful for maneuvering around plants and shrubs. The Greenworks 80V 16-Inch Brushless Trimmer features a variable-speed trigger that lets you adjust the speed continuously. The Greenworks 40V 16-Inch Brushless String Trimmer offers a 2-speed selection with a variable speed trigger, providing ultimate control. The 40V model’s specific mention of a 2-speed selection suggests it may have distinct power modes, whereas the 80V model emphasizes continuous adjustment. Both tools aim to provide consistent performance with less wear thanks to their brushless motors. The 40V model’s dual-speed option might offer more tailored control for different tasks, giving it a slight advantage in versatility.
Attachment Compatibility
Versatility can be expanded if the tool supports additional attachments. The Greenworks 40V 16-Inch Brushless String Trimmer is attachment capable, compatible with several Greenworks PAC series attachments including an edger, hedge trimmer, polesaw, cultivator, and blower. This allows you to use the same battery platform for multiple yard tasks. The data for the Greenworks 80V 16-Inch Brushless Trimmer does not mention attachment capabilities. It is presented as a standalone string trimmer. If you plan to use your trimmer for other landscaping tasks like edging or hedge trimming, the 40V model offers significantly more utility. The 80V model is focused solely on trimming performance.
