Husqvarna 966674401 T25 Tap Advance String Trimmer Head

The Husqvarna 966674401 T25 Tap Advance is a replacement string trimmer head listed for a range of Husqvarna models. Its cap-removable spool and split-spool design are intended to make reloading simpler and reduce line tangling, but confirm the trimmer model and attachment fit before buying.

At a glance

The spool comes off with the cap for reloading, so the listing says there is no need to turn the trimmer upside down.
The split-spool design is intended to minimize tangling and line welding. Arrows show the winding direction.
Listed for a range of Husqvarna 100–200 series models and other specified models. Check the compatibility list against your exact trimmer.

What to know before buying

Compatibility is listed for models including Husqvarna 122C, 122LK, 122RJ, 124C, 124L, 125C, 125L, 125LDX, 128C, 128CD, 128L, 128LD, 128LX, 128LDX, 128R, 128RJ, 130C, 130L, 330LK, 223L, 223R, 322C, 323C, 325C, 325CX and 326CX. Confirm your exact model and attachment fit before ordering. The listing also recommends the head for most straight- and curved-shaft trimmers and brushcutters, but does not substantiate universal compatibility.

Listing details to confirm

The listing details are inconsistent about line length and loading: one claim says the T25 holds 16.5 feet of .095-inch line and comes pre-wound, while customer feedback includes mixed reports about line capacity and one report of two short preloaded pieces. Confirm the expected line configuration if this matters to you.

Who is it for?

A good fit for

Husqvarna trimmer owners whose exact model is listed and who need a replacement head.
Users who want a head designed for cap-off spool reloading and .065- to .095-inch line.

Less suited to

Customer feedback highlights ease of installation and reported fit across various trimmer models. Durability and whether the part is OEM receive mixed comments, as does line capacity, including a report of short preloaded pieces. These reports are worth weighing if long-term use or ready-to-trim line quantity matters. The listing itself specifies compatibility with named Husqvarna models and .095-inch pre-wound line for the T25, but those claims do not resolve the reported variation.

Positive themes

Customers describe installation as quick and say the head works well.
Customers report fit across different models.

Mixed feedback

Durability feedback varies, with some customers reporting breakage after a short period.
Opinions about OEM authenticity differ.
Line-capacity feedback is mixed, including a report of only two short preloaded pieces.
