12-Inch Trimmer vs 13-Inch Trimmer Specs
Cutting Width
The Greenworks 40V 13-Inch Cordless String Trimmer offers a 13-inch cutting swath, providing a slightly wider path per pass than the 12-inch model. The Greenworks 40V 12-Inch Trimmer and Blower Combo features a 12-inch cutting width. This one-inch difference matters for large, open areas where efficiency is key. A wider swath reduces the number of passes needed to clear grass. For tight spaces around fences or garden borders, the narrower 12-inch head may offer better maneuverability. Both use a 0.065-inch auto-feed line system, ensuring consistent cutting performance regardless of the deck size. You should choose based on your lawn's open space.
Weight and Portability
Weight distribution significantly impacts user fatigue during extended trimming sessions. The Greenworks 40V 13-Inch Cordless String Trimmer weighs 9.92 pounds. In contrast, the Greenworks 40V 12-Inch Trimmer and Blower Combo weighs 16.5 pounds. This substantial difference is because the combo unit includes both the trimmer and a blower attachment. The lighter 13-inch trimmer is easier to hold and maneuver for long periods, especially when overhead or on slopes. It is also easier to store and transport. The heavier combo set provides more power for multiple tasks but requires more physical effort to handle. If you prioritize ease of use, the lighter option is superior.
Shaft Adjustability
Ergonomics and fit are crucial for comfort. The Greenworks 40V 13-Inch Cordless String Trimmer features a telescoping shaft that adjusts from 40 inches to 52 inches. It also includes a 7-position handle. This allows users from 5'2" to 6'4" to find a comfortable working height. The Greenworks 40V 12-Inch Trimmer and Blower Combo has a fixed length of 64.5 inches. While this fixed length may suit taller users, it lacks the flexibility to accommodate different heights or body types. The telescoping shaft on the 13-inch model reduces back strain by allowing you to stand upright. This adjustability makes the 13-inch trimmer more versatile for households with multiple users.
Functionality and Versatility
Your yard maintenance needs dictate the best tool choice. The Greenworks 40V 12-Inch Trimmer and Blower Combo includes a 390 CFM blower. This adds significant versatility, allowing you to clear leaves, grass clippings, and debris from driveways and walkways. The blower features a cruise control setting for consistent airflow. The Greenworks 40V 13-Inch Cordless String Trimmer is a dedicated trimmer and edger. It includes a steel edging guide for sharp lawn borders but lacks the blowing capability. If you need to clean hard surfaces after trimming, the combo set is more functional. If you only need trimming and edging, the single tool is sufficient.
Head Configuration
The design of the cutting head affects how you tackle different yard obstacles. The Greenworks 40V 13-Inch Cordless String Trimmer has a 7-position pivoting head. This allows you to trim under decks, edge sidewalks, or clear fence lines without changing tools. It converts between trimmer and edger modes in just three clicks. The Greenworks 40V 12-Inch Trimmer and Blower Combo features a commercial-grade trimmer head with a 3-year warranty. It is designed to slice through thick weeds up to 1 inch. While it is robust, it lacks the multi-angle pivoting capability of the 13-inch model. The pivoting head offers greater precision for detailed landscaping work.
Which Greenworks Trimmer Fits Your Yard

You want a lightweight, adjustable trimmer

The 13-inch cutting width offers a slightly wider path. You can switch between trimming and edging modes quickly. The 7-position pivoting head helps you reach under decks or along fences.
You prefer a dedicated string trimmer
If you only need trimming, this dedicated tool is simpler. It has a 13-inch cutting swath for fewer passes. The anti-vibration tech reduces fatigue during longer jobs. You get instant starts without pull cords. The steel edging guide is included for sharp borders. This model focuses solely on trimming performance without the extra weight of a blower attachment.
