Husqvarna T25 String Trimmer Head Replacement – Pre-Wound TitaniumForce, Fits 100–200 Series (.095" line)

Husqvarna T25 (966674401) is a user-friendly, pre-wound string trimmer head designed to make reloading faster, reduce line tangles, and fit a wide range of straight and curved shaft trimmers.

This replacement T25 tap-advance trimmer head is engineered by Husqvarna for homeowners and DIY landscapers who want a reliable, low-fuss solution for routine trimming and edging. It accepts .065"–.095" line (comes pre-wound with TitaniumForce line), uses a removable spool cap for tool-free reloading, and features design details that minimize line welding and tangles. The head fits many Husqvarna 100–200 series models and provides clear winding guidance so you can get back to work quickly.

How does the T25 make reloading faster and easier?

The T25 head uses an easy-to-reload spool that comes off with the cap, so you don’t have to flip the trimmer over to replace line. An open eyelet lets the cord feed smoothly through the spool, and directional arrows show the correct winding path to eliminate guesswork.

• Cap-attached spool removes for straightforward access
• Open eyelet for smooth line feeding while winding
• Arrows indicate proper winding direction to prevent mistakes

It holds .065" to .095" line and ships pre-wound with either .080" (T25C) or .095" (T25) TitaniumForce line depending on the SKU.

How does the design reduce tangles and improve line retention?

The split spool architecture separates line segments to limit contact and reduce the chance of welding or tangling. Two key slots lock the line ends while you replace the cap, keeping windings secure and preventing unwrapping before installation.

• Split spool reduces line-to-line contact and tangles
• Key slots secure line ends during cap replacement
• Robust cap and spool geometry designed for reliable feeding in field conditions
