Frequently Asked Questions
1. How do I choose the correct Stihl trimmer head for my machine?
Check your trimmer or brushcutter model number and match it with the recommended Stihl trimmer heads listed in the guide. Each AutoCut, TrimCut, PolyCut and DuroCut head is compatible with specific models, and our quick‑reference chart makes it easy to find the right fit.
2. What is the difference between AutoCut, TrimCut, PolyCut and DuroCut heads?
- AutoCut – Bump‑feed heads that release line automatically as you work.
- TrimCut – Semi‑automatic heads where you manually set the line length.
- PolyCut – Features durable plastic blades for tougher vegetation.
- DuroCut – Pre‑cut line system designed for dense grass and heavy-duty trimming.
Our guide explains each type and helps you choose based on your needs.
3. Can I buy replacement line and spools for my Stihl trimmer head here?
Yes. The guide links directly to replacement cutting line, pre‑cut segments, spools and blades for all major Stihl head types. Simply click the Trimmer Line link at the bottom of the guide.
4. Are there videos showing how to fit and use Stihl trimmer heads?
Yes— trimmer heads with (v) next to them in the guide include official Stihl how‑to videos showing how to load line, replace spools, and fit the head correctly. Just click the hyperlinked images to watch.
5. How do I know which line thickness my Stihl trimmer head uses?
Different heads require different line diameters. Your machine’s manual will list the correct size, but the guide also includes recommended line thicknesses for each trimmer head to make selection easy.
6. Will these trimmer heads fit non‑Stihl machines?
Stihl trimmer heads are designed specifically for Stihl brushcutters and grass trimmers. Compatibility with other brands isn’t guaranteed, so it’s recommended to use them only with Stihl equipment.
7. How often should I replace my trimmer head or spool?
Replace the spool or line when it becomes worn, snaps frequently, or feeds inconsistently. Trimmer heads last longer, but should be replaced if the housing is cracked, the bump knob is damaged, or the head no longer feeds line correctly
8. Why does my line keep snapping?
All trimmer line can become brittle over time. Top Tip... keep a damp sponge in the spare donut of line. This keeps the line flexible and helps prevent premature breakage. If your spare trimmer line has sat for a while, place it in water for 24hrs before use.
