Your Guide to Choosing the Best String Trimmer Head
The string trimmer head is the part of your weed whacker that actually does the cutting. A good head makes trimming fast and easy. A bad one causes constant frustration. Choosing the right one depends on your yard size and the type of trimming you do. This guide helps you pick the perfect replacement head.
1. Key Features to Look For
When you shop for a new trimmer head, several features really matter. Think about how often you use your trimmer.
Ease of Reloading
This is perhaps the most important feature. Some heads require you to take the whole thing apart to put in new string. Others let you wind the string right on the spool—this is called “bump feed” or “speed feed.”
- **Bump Feed:** You tap the head on the ground to release more line. This is fast and convenient for most homeowners.
- **Fixed Line:** You manually thread fixed lengths of line through holes. This gives you precise line length but takes longer to reload.
Line Diameter Compatibility
Trimmer heads only work with certain thicknesses of string (measured in inches, like 0.080″). Check your trimmer’s manual. Buying a head that matches your preferred string thickness saves you hassle later.
Trimmer Type Compatibility
Not all heads fit all trimmers. You need to know if your trimmer uses a fixed bolt, a specific thread size (like M10 or M12), or a quick-change adapter. Always confirm the fitment before buying.
2. Important Materials That Matter
The material of the head affects how long it lasts and how well it handles tough jobs.
Most modern, durable trimmer heads use strong plastic or metal housing. High-quality plastic, often reinforced with fiberglass, resists cracking when bumped against concrete.
Metal vs. Plastic
- **Metal Heads (Aluminum or Steel):** These are tough. They handle heavy-duty use, like cutting thick weeds or edging aggressively. They last a very long time.
- **Plastic Heads:** These are lighter. They are perfect for light residential use. They cost less money too.
The internal spool mechanism should also be sturdy. Cheap plastic spools often wear out quickly, causing the line to tangle inside the head.
3. Factors That Improve or Reduce Quality
Quality is often found in the small details of the design. A well-designed head works smoothly; a poorly designed one jams.
Reducing Jams and Wear
Heads with fewer moving parts often work better over time. Complex mechanisms can trap dirt and debris, which reduces performance. Look for heads that feature sealed bearings or simple, robust winding systems. If the eyelets (where the line exits the head) are made of metal, they will not wear down as fast as plastic ones. Metal eyelets significantly improve durability.
Ease of Installation
A quality head installs quickly. If the adapter system is confusing or requires many washers and spacers, it lowers the quality of your user experience. Simple, secure attachment is key.
4. User Experience and Use Cases
How you use your trimmer dictates the best head for you.
Homeowner Use Cases (Light Trimming)
If you only trim around flower beds and light grass once a week, a simple, inexpensive bump-feed plastic head works great. You value ease of reloading over extreme toughness.
Professional Use Cases (Heavy Duty)
If you trim every day, you need a heavy-duty, fixed-line, or high-end metal head. Professionals often prefer fixed-line heads because they know exactly how much string they have left. This precision helps them maintain consistent cutting height throughout the job.
Remember: A head that is too heavy can strain your trimmer motor, especially on smaller electric models. Always match the head weight to your trimmer’s power.
10 Frequently Asked Questions About String Trimmer Heads
Q: How often should I replace my string trimmer head?
A: You should replace the head only when the housing cracks, the bump mechanism breaks, or the internal spool constantly jams. If the string just wears out, you only replace the line, not the whole head.
Q: Can I put a universal head on any trimmer?
A: Sometimes, but usually not directly. Most universal heads come with several adapters. You must match the adapter size (like thread pitch) exactly to your trimmer shaft for safe operation.
Q: What is the best string size for most yards?
A: The most common and versatile string diameter is 0.080 inches. It cuts grass well and handles light brush without straining smaller engines.
Q: Does a metal head cut better than a plastic head?
A: A metal head does not inherently cut better, but it lets you use thicker, tougher line. This thicker line cuts heavier weeds more effectively.
Q: What does “line spooling” mean?
A: Line spooling is the process of winding the cutting line onto the internal reel inside the trimmer head. Fast-loading heads make this process very simple.
Q: Why does my string keep breaking off inside the head?
A: This usually means the line is old, dry, or you are hitting extremely hard objects like rocks. Also, check that the line feeds smoothly through the eyelets; rough eyelets can cut the line.
Q: Should I use a fixed line or a bump feed head?
A: Use bump feed for general yard work. Use fixed line if you frequently trim in very rough areas where you need maximum line strength and control.
Q: How do I know if my trimmer needs a left-hand or right-hand thread head?
A: Most consumer trimmers use a standard right-hand thread (tightens clockwise). However, always check your owner’s manual to be certain before purchasing a replacement head.
Q: Can I use a trimmer head designed for gas trimmers on an electric trimmer?
A: Yes, if the mounting adapter matches the shaft size. However, be careful. Heavy metal heads can overload and damage the motor on low-powered electric trimmers.
Q: What is the purpose of the eyelets on the trimmer head?
A: The eyelets are small holes or guides where the cutting line exits the head. They guide the line out straight and often feature durable inserts (like metal) to prevent the plastic housing from wearing away.
