Types of Strimmer Heads

Strimmer heads come in a variety of shapes, sizes, and materials, each with its own advantages and disadvantages. Here are the most common types:

Nylon Line Heads:

• Pros: Affordable, versatile, lightweight
• Cons: Can break easily, not suitable for heavy-duty applications

Metal Blade Heads:

• Pros: Durable, long-lasting, can cut through thick vegetation
• Cons: Heavy, can damage fences and other objects

Plastic Blade Heads:

• Pros: Lightweight, safer than metal blades, can be used on rough surfaces
• Cons: Not as durable as metal blades, can wear out quickly

Brush Cutter Heads:

• Pros: Designed for heavy-duty cutting, can handle thick brush and small trees
• Cons: Expensive, require a powerful strimmer

Choosing the Right Strimmer Head

The best strimmer head for you will depend on your specific needs. Consider the following factors:

• Type of vegetation: Nylon line heads are best for grass and weeds, while metal blade heads are more suited for thicker vegetation.
• Cutting surface: Plastic blade heads are ideal for rough surfaces, such as gravel or dirt, while metal blade heads can also be used on smooth surfaces.
• Power of your strimmer: Brush cutter heads require a powerful strimmer to operate effectively.

Replacing a Strimmer Head

Replacing a strimmer head is a relatively simple task that can be done in a few steps:

1. Unplug the strimmer: Always unplug the strimmer before attempting any maintenance.
2. Locate the retaining nut: Find the nut that holds the strimmer head in place.
3. Loosen the nut: Use a wrench or spanner to loosen the nut counterclockwise.
4. Remove the old head: Once the nut is loosened, pull the old head off the drive shaft.
5. Install the new head: Align the new head with the drive shaft and push it on until it fits snugly.
6. Tighten the nut: Use the wrench or spanner to tighten the nut clockwise until it is secure.

Troubleshooting Common Strimmer Head Problems

Here are some common problems you may encounter with strimmer heads and how to resolve them:

• The strimmer head is not cutting:
• Check if the line is extended or needs replacing.
• Ensure the head is properly installed and tightened.
• The strimmer head is wobbling:
• Check if the head is damaged or cracked.
• Tighten the retaining nut to secure the head.
• The strimmer head is throwing grass:
• Reduce the length of the line or use a thicker line.
• Ensure the head is level and not tilting too far in one direction.
