Only meant for the Husqvarna 115iL & 136LiL (as of 2018) and thus has thread of M8

This trimmer head can rotate both clockwise and counterclockwise. Made specifically for our battery powered trimmers. Exclusively designed by Husqvarna the T25B trimmer head features a semi-automatic wire feed that we also call Tap'n go.

These trimmer heads have automatic feed-through when the head is pressed to the ground, so the user has total control. There is no need to turn off the machine or remove it from the harness while extending the wire.
