Description
Overview:
This M10 x 1.25 T25 bump feed trimmer head is a non-genuine replacement designed for straight-shaft brushcutters and grass trimmers, including Husqvarna 129 and 128L. It uses a semi-automatic "bump" mechanism to release line when tapped on the ground, keeping cutting performance consistent without stopping the machine. The housing is a tough polymer for durability, with an easy-to-spot orange bump knob for quick line advance. Built to take standard 2.4 mm trimmer line, it suits regular grass, edging, and light brush work. The M10 x 1.25 thread provides a secure attachment where this specification is required, making it a practical swap for worn or damaged heads and a direct replacement for Husqvarna part number 578 44 61-01.
Key Features:
- Non-genuine replacement compatible with T25-style fitment
- M10 x 1.25 thread for secure mounting where specified
- Semi-automatic bump feed for quick line advance during work
- Robust polymer body with impact-resistant design for long service life
- Supports 2.4 mm line for efficient cutting in grass and light weeds

- Suitable for domestic, trade, and grounds maintenance use
Typical Applications:
