Husqvarna T45X Head (M12 Variant)
The Husqvarna T45X M12 Head is a durable, semi-automatic trimmer head built for users who demand strong performance and reliability. Featuring the Tap’n Go system, it feeds line automatically when you tap the head on the ground, so you can keep trimming without stopping. It includes a ball bearing resting surface to reduce wear and extend lifetime, especially under tough conditions.
Robust features & durability
This head includes an open eyelet design, which helps you load new line more easily. Husqvarna also built in exchangeable parts so you only replace what needs changing. Its durability rating is 5/5, so it’s made to withstand heavy grass cutting and frequent use.
Cord size & suitability
The T45X Head supports cord sizes from 2.7 mm up to 3.3 mm. These larger line diameters give increased cutting power for tougher or thicker vegetation. Its performance works best on heavy grass and similar demanding trimming jobs.
