6 Best Alternatives to the RYOBI 40V Attachment Capable 15" (2026)

How the alternatives compare

Makita 40V max Brushless 15" String Trimmer

The Makita 40V max Brushless 15" String Trimmer shares the 15-inch cutting width but uses a brushless motor for optimized performance under heavy loads. It weighs 7.09 pounds, which is lighter than the 11-pound RYOBI model. This makes it easier to handle for extended periods. The tool is attachment capable, similar to the RYOBI, allowing you to switch between yard tasks. However, it is designed for users who already own Makita 40V XGT batteries. You must purchase batteries separately. If you value high torque and lower weight over the RYOBI ecosystem, this is a strong alternative. It delivers gas replacement power in a compact form factor.

RYOBI 40V 17-Inch Attachment Capable Trimmer

The RYOBI 40V 17-Inch Attachment Capable Trimmer increases the cutting swath to 17 inches, covering more ground per pass than the 15-inch original. It also uses a brushless motor for quiet operation and efficiency. The weight remains identical at 11 pounds, maintaining ease of use. Like the original, it features an attachment-capable shaft for versatility. The trade-off is a slightly larger cutting width, which may be too wide for tight spaces. This model is ideal if you prioritize a wider cut and quieter performance. It fits users who want to stay within the RYOBI 40V battery system but need more coverage area. The 17-inch path reduces the number of passes required for larger lawns.

WORX 40V 15-Inch Trimmer and Blower Combo

The WORX 40V 15-Inch Trimmer and Blower Combo offers a dual-function design for users seeking a complete yard cleanup solution. It shares the 15-inch cutting width and 40V voltage with the original. However, it weighs 20 pounds, which is significantly heavier than the 11-pound RYOBI. This added weight may affect maneuverability. The key advantage is the included blower attachment, allowing you to switch trimming and blowing tasks without changing tools. It is best for those who value convenience and a shared battery system. If you want to reduce the number of separate tools in your shed, this combo is practical. It sacrifices lightweight handling for multifunctionality.

WORX 15-Inch Brushless 40V String Trimmer

The WORX 15-Inch Brushless 40V String Trimmer matches the 15-inch cutting width but weighs only 9.42 pounds. This is lighter than the 11-pound RYOBI, making it easier to carry and operate. It features a brushless motor for improved efficiency and runtime. The tool is designed for users who already own WORX 40V batteries. You must purchase batteries separately. It lacks an attachment-capable shaft, limiting its versatility compared to the RYOBI. This model is ideal if you prioritize lightweight handling and runtime over multi-tool compatibility. It is a solid choice for basic trimming tasks where weight is a primary concern. The compact design suits smaller yards or users with physical limitations.

Greenworks 40V 16-Inch Brushless String Trimmer

The Greenworks 40V 16-Inch Brushless String Trimmer offers a 16-inch cutting width, which is wider than the 15-inch original. This allows you to cover more area with each pass. It weighs 11.3 pounds, slightly heavier than the RYOBI. The brushless motor provides efficient performance and longer runtime. Like the RYOBI, it is attachment capable, enabling you to use various yard tools. This model is best for users who want a wider cut and attachment versatility. It fits those who prioritize coverage area over minimal weight. The 16-inch path reduces mowing time for larger lawns. It is a practical alternative if you need a balance between cutting width and multi-tool compatibility within the Greenworks 40V system.

Kobalt 40V Max 15-Inch Straight Shaft Trimmer

The Kobalt 40V Max 15-Inch Straight Shaft Trimmer shares the 15-inch cutting width and 40V voltage with the original. It features a straight shaft design, which is straightforward for basic trimming tasks. The tool weighs less than the RYOBI, though exact weight is not specified. It is designed for users who already own Kobalt 40V batteries. You must purchase batteries separately. It lacks an attachment-capable shaft, limiting its versatility. This model is ideal if you want a simple, dedicated trimmer. It suits users who prioritize compatibility and ease of use over multi-tool functionality. The straight shaft offers direct control for precise trimming. It is a solid choice for those who need a reliable tool for standard yard maintenance.
