How to Put a Brush Cutter on a STIHL Weedeater 

A STIHL weedeater, also known as a trimmer, is a versatile tool that can handle various types of vegetation, including weeds, grass, and other unwanted plants. However, when dealing with thicker and tougher vegetation, the standard trimmer head may not be enough to handle the job. 

This is where the brush cutter attachment comes in handy. A brush cutter is a heavy-duty attachment that can be attached to a STIHL weedeater to provide additional power and efficiency for tackling tough vegetation. 

In this article, we will go over the steps on how to attach a brush cutter to a STIHL weedeater. Before we start, make sure that you have all the necessary tools and equipment on hand, including the brush cutter attachment, a screwdriver, and a wrench. 

Step 1: Removing the Trimmer Head

To attach the brush cutter attachment, you first need to remove the standard trimmer head from the weedeater. To do this, turn off the engine and disconnect the spark plug to prevent accidental startups. 

Locate the knob or lever that holds the trimmer head in place. This is usually located near the end of the shaft. Turn the knob or lever counterclockwise to release the trimmer head. Depending on the model, you may need to use a screwdriver or a wrench to remove the trimmer head. 

Step 2: Attaching the Brush Cutter Blade

Once you have removed the trimmer head, you can now attach the brush cutter blade. The brush cutter blade comes with a spacer and bolts that you will use to attach it to the shaft of the weedeater. 

Insert the spacer onto the shaft and align the holes on the spacer with the holes on the blade. Secure the blade to the spacer with the bolts provided. Make sure to tighten the bolts securely to prevent the blade from coming loose during operation. 

Step 3: Attaching the Brush Cutter Housing

The brush cutter housing is the part of the attachment that covers the blade and protects you from the rotating parts. Attach the brush cutter housing to the spacer and blade by aligning the holes and securing them with bolts. 

Step 4: Installing the Safety Guard

The safety guard is an important component of the brush cutter attachment, as it helps to prevent injury to the user. The safety guard should be attached to the brush cutter housing in a way that provides complete coverage of the blade. 

Step 5: Testing the Attachment

Once you have securely attached the brush cutter attachment, you can now test it to make sure it’s functioning properly. Start the engine and allow it to run for a few minutes. Observe the blade and check for any wobbling or other signs of looseness. 

If everything is functioning properly, you can now begin using the brush cutter attachment to tackle tough vegetation. However, it is important to exercise caution and follow all safety guidelines when using the brush cutter. 

Safety Precautions:

Before using a brush cutter attachment, it is important to take safety precautions to prevent injury. Always wear protective gear, including safety glasses, heavy-duty gloves, and sturdy shoes with non-slip soles. 

Make sure to wear long pants and a long-sleeved shirt to protect your skin from flying debris. Additionally, always follow the manufacturer’s safety guidelines and never operate the brush cutter near people, pets, or other potential hazards. 

Never reach over or near the blade while the engine is running, as the rotating blade can cause serious injury. 

Maintenance:

To keep your brush cutter attachment in good working order, it is important to perform regular maintenance. After each use, inspect the blade and housing for any damage or signs of wear. If you notice any issues, repair or replace the affected parts as soon as possible. 

Additionally, keep the blade sharp and lubricated with oil to ensure that it cuts efficiently and does not become damaged. Regularly clean the brush cutter housing to prevent dirt and debris from accumulating and interfering with its operation. 

Choosing the Right Brush Cutter Blade:

There are various types of brush cutter blades available, including metal blades, nylon trimmer lines, and plastic blades. When choosing a blade, consider the type of vegetation you will be cutting and the size of the brush. 

Metal blades are ideal for heavy-duty tasks, such as cutting through thick brush and small trees. The nylon trimmer line is best for lighter tasks, such as trimming grass and weeds. Plastic blades are suitable for light to medium tasks and are ideal for users who are not familiar with using metal blades. 

Bottom Line

In conclusion, a brush cutter attachment is a valuable tool for anyone who needs to tackle tough vegetation. With its heavy-duty power and versatility, it can make quick work of even the toughest jobs. 

By following the steps outlined in this article and taking the necessary safety precautions, you can safely and effectively attach a brush cutter to your STIHL weedeater. Happy cutting!
