Husqvarna T25 Vs T35 Trimmer Head
When it comes to replacing or upgrading your trimmer head, the Husqvarna T25 and T35 are two of the most popular bump-feed options available.
While they might look similar at a glance—and even function in similar ways—there are a few key differences that can make one better suited to your yard work than the other.
In this long blog, we’ll break down the similarities and differences between these two models so you can choose the one that fits your yard work needs best.
What They Have in Common
Both the T25 and T35 are designed with convenience in mind, especially when it comes to reloading and line feeding. They both use Husqvarna’s Tap-Advance bump feed system, which means you just tap the head on the ground to release more line. No need to stop and fuss with the spool mid-job — it keeps you moving and trims down your work time.
Reloading is also pretty straightforward with either head. Both feature a top-loading spool with arrows that guide you on how to wind the line correctly. They even use a split-spool design, which helps prevent the line from tangling inside the head — a small detail, but one that saves a lot of headaches.
Durability is another shared trait. Both heads are built from tough plastic that’s meant to withstand regular trimming, bumps, and scrapes. They may not look flashy, but they’re designed to last through season after season of lawn care.
The Key Differences
Even with their similarities, the T25 and T35 serve different levels of trimming work. The biggest difference lies in line capacity. The T25 holds about 16.5 feet of .095-inch line, while the T35 can carry roughly 28 feet of .095-inch line and even supports thicker line up to .105-inch. In practice, this means the T35 can handle tougher weeds and go longer without needing a reload.
Compatibility is another big difference. The T25 is made for Husqvarna’s 100–200 series trimmers, and it works on both straight and curved shafts. The T35, however, is compatible with Husqvarna’s 100–500 series straight-shaft trimmers, giving it a much wider range of use. Some T35 models even come in a universal version with adapters, making them fit other trimmer brands.
Size and weight also come into play. The T25 is lighter and easier to maneuver, which makes it great for detailed edging and smaller jobs. The T35 is larger and a bit heavier, but that extra bulk translates into more line capacity and stronger cutting performance — perfect for bigger yards or tougher vegetation.

Which One Should You Choose?
Choosing between the T25 and T35 really depends on your yard and your workload. If you’ve got a smaller yard and mainly deal with grass and light trimming, the T25 is more than enough. It’s lightweight, easy to handle, and a perfect fit for Husqvarna’s smaller trimmers.
On the other hand, if you’re facing larger areas, thicker weeds, or frequent trimming sessions, the T35 is the smarter choice. Its higher line capacity, ability to use thicker line, and compatibility with more powerful trimmers make it the go-to for heavy-duty yard work.
Final Thoughts
The Husqvarna T25 and T35 trimmer heads may look alike, but their differences in capacity, compatibility, and weight make them suited for very different trimming needs. The T25 shines in lightweight, everyday trimming, while the T35 steps up for bigger, tougher jobs. No matter which one you pick, both carry Husqvarna’s reputation for quality and ease of use, so you’re getting a reliable tool either way.
