Understanding Trimmer Heads
Trimmer heads are the functional part of your STIHL trimmer that holds the cutting line. They come in various designs tailored to different applications. Understanding these variations will help you select the best trimmer head for your specific needs.

Fixed line trimmer heads are simple and easy to use. They hold pre-cut lengths of line that can be replaced when worn out. This option is ideal for homeowners who maintain small to medium-sized yards.
Bump Feed Trimmer Heads
Bump feed trimmer heads are popular due to their ease of use. By simply tapping the head on the ground, more line is fed out. This is a great choice for those who require frequent line extensions while working in larger areas.
Automatic Feed Trimmer Heads
Automatic feed trimmer heads provide the advantage of not needing to stop and manually feed new line. As you operate the trimmer, line is released as needed, making it perfect for extensive areas that require continuous cutting.
Brush Cutter Heads
When dealing with thick vegetation, brush cutter heads are the go-to option. They are designed to handle denser growth and larger brush, making them suitable for more demanding landscaping tasks.
Edger Heads
Edger heads are specialized for creating clean lines along sidewalks and flower beds. Their design allows for precision cutting, which is essential for maintaining a professional appearance in landscaping.
How to Replace a Trimmer Head
Replacing a trimmer head may seem daunting, but it can be accomplished quickly with the right tools and knowledge. Follow these steps for a seamless replacement process.
Step 1: Safety First
Always ensure your trimmer is turned off before beginning any maintenance work. For petrol models, remove the spark plug, and for cordless models, disconnect the battery.
Step 2: Prepare Your Workspace
Find a clean, flat surface to work on. Gather your tools, including a lock pin or Allen key, which will be used to secure the shaft during replacement.
Step 3: Remove the Old Trimmer Head
Insert the lock pin or Allen key into the gearbox hole and rotate the shaft until it locks into place. This prevents the shaft from turning while you unscrew the old trimmer head.
Step 4: Install the New Trimmer Head
Align the new trimmer head with the shaft. Carefully screw it on in the opposite direction of removal. Ensure it is secured tightly to avoid any accidents while operating the trimmer.
Step 5: Test the Replacement
Before using the trimmer, check that the new head is securely attached. Power on the trimmer and observe its performance to confirm everything is functioning correctly.
Maintenance Tips for Trimmer Heads
Regular maintenance can extend the life of your trimmer head. Here are a few tips to keep in mind.
Clean the Trimmer Head
After each use, take the time to clean the trimmer head. Remove any debris, grass clippings, or dirt that may have accumulated. This can prevent clogs and ensure smooth operation during your next use.
Inspect the Cutting Line
Regularly check the cutting line for wear and replace it as needed. A worn line can affect the performance of your trimmer and lead to inefficient cutting.
Store Properly
When not in use, store your trimmer in a dry place. This can help prevent rust and damage to the trimmer head and other components.
