Husqvarna T25 String Trimmer Head Replacement — Pre-wound Titanium Force .095" Line, Easy Top-Side Reload

Husqvarna T25 is a user-friendly replacement string trimmer head that reloads without flipping the tool and comes pre-wound with Titanium Force line for fast, reliable yard trimming.

The Husqvarna 966674401 T25 Tap Advance trimmer head is built to simplify routine lawn care and light brush trimming. Designed for compatibility with many Husqvarna straight- and curved-shaft trimmers and brushcutters, this head accepts .065" to .095" line and ships pre-wound with either .080" (T25C) or .095" (T25) Titanium Force line, so you can get back to work quickly. Its split-spool design and open eyelet reduce tangles and make restringing straightforward, while directional arrows and keyed spool slots guide correct installation.

How does the T25 make reloading faster and less messy?

The T25 features an easy-remove spool that lifts out with the cap, so you don't need to invert the trimmer to change line. An open eyelet helps feed new line smoothly, and arrows printed on the spool show the correct winding direction to avoid guesswork.

• Removable cap-and-spool assembly for top-side reloading
• Open eyelet for simple line feeding
• Arrows indicate correct winding direction
• Two keyed slots lock the line when replacing the cap

Will this head fit my Husqvarna trimmer model?

The T25 is compatible with a wide range of Husqvarna 100–200 series trimmers and several older models listed by part. It works on many straight- and curved-shaft string trimmers and brushcutters that accept the T25 mounting and line size.

• Compatible with numerous Husqvarna models such as 122C, 125L, 128LD, 323C, 325C, and others
• Accepts .065" to .095" trimmer line sizes
• Check your trimmer manual or parts list for T25 compatibility

Does the pre-wound line save time, and what line does it use?

The T25 ships pre-wound with Titanium Force line (.080" for T25C or .095" for T25), so you can install and use it immediately without winding. Pre-wound spools reduce setup time and are handy as a replacement when you're mid-project.

• Supplied pre-wound with Titanium Force line for immediate use
• Holds up to 16.5 feet of .095" line for longer runtimes
• Compatible with line gauges from .065" to .095" for flexibility

How does the T25 reduce tangles and line welding?

The split-spool architecture separates line paths to limit contact points that cause tangling or welding. Combined with the keyed line slots and clear winding indicators, this design keeps the spool orderly during operation and replacement.

• Split spool reduces internal line friction and tangles
• Key slots secure ends of the line during cap replacement
• Clear directional markings remove winding uncertainty

Who is this product for? The Husqvarna T25 trimmer head is ideal for homeowners, DIY landscapers, and anyone who wants a quicker, less-fussy way to reload trimmer line. It suits users of compatible Husqvarna trimmers who value tidy line management, straightforward installation, and the convenience of a pre-wound spool — a practical upgrade for routine lawn maintenance, spring cleanup, and property edge work.
