Greenworks vs Kobalt Specs
cutting width
The Greenworks 40V 12-Inch Trimmer and Blower Combo features a 12-inch cutting swath. This width is suitable for precise edging along driveways, walkways, and garden borders. It handles weeds up to one inch thick with its commercial-grade head. In contrast, the Kobalt 40V Max 15-Inch Straight Shaft Trimmer offers a wider 15-inch cutting swath. The broader deck covers more ground per pass, which can reduce the time needed for larger open areas. If you prioritize speed on wide grassy patches, the Kobalt provides a larger cutting area. The Greenworks model is better for tight, detailed work along edges.
shaft type
The Kobalt tool uses a straight shaft design. This configuration is often preferred for traditional string trimmers and can offer better balance for some users when tackling flat terrain. The Greenworks model data does not explicitly specify the shaft shape in the provided key specs or attributes. However, the length is listed as 64.5 inches, which suggests a longer reach compared to the Kobalt's 38-inch length. The Greenworks unit is part of a combo system, which may influence its overall balance and handling characteristics. You should consider whether you prefer a dedicated straight shaft or a longer reach for your specific yard layout.
power source
Both brands operate on a 40V platform. The Greenworks 40V 12-Inch Trimmer and Blower Combo runs on a 2.0 Ah battery. This battery is included in the package and charges in 60 minutes. It powers both the trimmer and the 390 CFM blower in the combo set. The Kobalt 40V Max 15-Inch Straight Shaft Trimmer is sold as a bare tool. The product data explicitly states that the battery is not included. You must purchase a compatible 40V Kobalt battery separately. If you already own a Kobalt battery, the Kobalt tool is ready to use. If you are starting fresh, the Greenworks combo provides the necessary power source immediately.
weight
The Greenworks combo unit weighs 16.5 pounds. This weight includes both the trimmer and the blower components. The description notes a balanced design that is 30% lighter than gas alternatives, which helps reduce fatigue during extended use. The Kobalt 40V Max 15-Inch Straight Shaft Trimmer weight is not listed in the provided data. Since the Kobalt is sold as a bare tool, its weight will vary depending on the battery you attach. Generally, bare tools are lighter than combo kits, but you must account for the battery weight when holding the tool. For a direct comparison, the Greenworks weight is a fixed value you can rely on for planning.
line feed system
The Greenworks 40V 12-Inch Trimmer and Blower Combo features an auto-feed line system. This mechanism allows the trimmer line to extend automatically as it wears down, ensuring consistent cutting performance without needing to tap the head on the ground. The Kobalt 40V Max 15-Inch Straight Shaft Trimmer line feed system is not specified in the provided data. It may use a bump-feed or auto-feed design, but the product details do not confirm this. If automatic line extension is a priority for you, the Greenworks model offers this feature clearly. You should check the Kobalt packaging or manual to verify its line feed method before purchasing.
Which Cordless Trimmer Suits Your Yard
Users wanting a trimmer and blower combo
The Greenworks 40V 12-Inch Trimmer and Blower Combo includes a 390 CFM blower. This 40V system uses a 2.0Ah battery for both tools. It offers a 12-inch cutting swath for precise edging.

Those needing a wider cutting path
The Kobalt 40V Max 15-Inch Straight Shaft Trimmer provides a 15-inch cutting swath. This is wider than the Greenworks 12-inch model. It features a straight shaft design for comfortable handling. Note that this is a bare tool and does not include a battery. You need to supply your own 40V battery for operation.
People who prefer a single tool
The Kobalt model is a bare tool string trimmer only. It does not include a blower or other attachments. This suits you if you already own compatible batteries and want a dedicated trimmer. The 15-inch width covers more ground per pass. It is a straightforward option for basic edge trimming tasks.
