Husqvarna T25 Trimmer Head

Husqvarna T25 Trimmer Head – Easy Load Tap ‘n Go Cutting Head

The Husqvarna T25 Trimmer Head is a high-quality, semi-automatic cutting head designed for both homeowners and professionals seeking efficiency, durability, and ease of use. Engineered by Husqvarna, this versatile trimmer head is ideal for general grass trimming and light brush cutting.

Featuring Tap ‘n Go technology, the T25 allows users to release new trimmer line with a simple tap of the head against the ground—no need to stop the machine. This feature ensures continuous operation and less downtime, especially useful when covering large areas.

One of the key highlights of the T25 is its easy-loading spool system. With a split spool design, winding new line is quick, simple, and tangle-free—no disassembly required. It comes preloaded with 2.0mm or 2.4mm trimmer line (depending on version) and supports various line diameters, making it adaptable to a wide range of trimming tasks.

The T25 Trimmer Head is compatible with a variety of Husqvarna curved and straight shaft trimmers, as well as other brands using similar fitment systems. It’s a great replacement part for models like the Husqvarna 122C, 128LD, 223L, 129L, 322L, and more.

Built with robust materials for long-lasting performance, the T25 is ideal for trimming grass around trees, fences, flower beds, and hard-to-reach corners with clean, precise cuts.
