RYOBI 40V String Trimmer 15" Bare Tool — Attachment-Capable, Up to 71 Min Runtime

The RYOBI 40V 15" Attachment-Capable String Trimmer is a battery-powered trimmer that delivers gas-like performance, attachment versatility, and up to 71 minutes of runtime (battery sold separately).

Built to join the RYOBI 40V family, this 15" string trimmer replaces routine gas maintenance with a lightweight, trigger-controlled cordless design. Its motor provides more cutting power than many 21cc gas models, while the Expand-It attachment capability converts the unit into multiple tools to handle edging, brush clearing, and other yard tasks. The REEL EASY+ bump-feed head makes line changes quick and the adjustable 13"–15" cut swath lets you prioritize run time or a wider cut.

How does this trimmer compare to a gas-powered unit?

The RYOBI 40V trimmer is engineered to match or exceed the cutting performance of typical 21cc gas trimmers without fuel mixing, spark plugs, or oil changes. You get near-gas power from a clean, quieter battery platform with instant start at the pull of a trigger. Because it’s part of the 40V ecosystem, any RYOBI 40V battery fits and powers the tool.

• Delivers more power than many 21cc gas trimmers for comparable cutting results
• No gas-related maintenance: no carburetor, fuel storage, or oil
• Instant electric start and quieter operation for neighborhood-friendly use

What attachment options and versatility does it offer?

This unit is EXPAND-IT attachment capable so the front-end accepts a range of RYOBI power-head attachments to convert the trimmer into blowers, dethatchers, or other yard tools. It also fits many universal gas-style attachments, helping you consolidate equipment and reduce storage footprint. The included straight-shaft adapter makes swapping attachments fast and secure.

• Compatible with RYOBI EXPAND-IT line of attachments
• Accepts many universal gas-style attachments for added flexibility
• Included straight-shaft EXPAND-IT adapter for easy changeover

How do runtime and cutting options affect performance?

Runtime depends on battery capacity; using a 40V 4Ah battery yields up to 71 minutes, letting you tackle larger yards on a single charge. The cut swath adjusts between 13" and 15", so you can choose a narrower setting to extend runtime or a wider setting for faster cutting. A variable-speed trigger provides control when trimming along fences, beds, or obstacles.

• Up to 71 minutes of runtime with a 40V 4Ah battery (battery sold separately)
• Adjustable 13"–15" cut swath for runtime or wider coverage
• Variable-speed trigger for precise trimming next to landscape features

How easy is it to maintain and reload line?

RYOBI's REEL EASY+ bump-feed head is designed to reload trimmer line in under a minute, streamlining regular upkeep. Without gas engine components, common maintenance tasks are reduced to occasional spool refills and general cleaning. The package includes a .080" replacement line to get you started.

• REEL EASY+ head: quick line reloads in under 60 seconds
• Fewer maintenance points than gas: no fuel, spark plugs, or carburetor care
• Includes .080" replacement line and grass deflector for immediate use
