Introduction
Changing the cutting line on a Craftsman weed eater is a routine maintenance task that keeps your trimmer running efficiently and extends the life of the tool. Whether you own a gas‑powered model, a cordless battery unit, or an electric plug‑in version, the basic principle remains the same: remove the old spool, load fresh line, and reassemble the head.

Understanding Your Craftsman Weed Eater
Craftsman offers several trimmer head designs, and knowing which one you have determines the exact loading method. The most common heads are the bump‑feed, fixed‑line, and dual‑line models. Each has a slightly different spool geometry, but the overall process of swapping line is similar.
Types of Heads
Bump‑feed heads release line when you tap the head on the ground. They usually have a single spool that holds a continuous length of line. Fixed‑line heads come pre‑wound with a set length of line; you replace the entire spool when the line runs out. Dual‑line heads feed two strands simultaneously, providing a wider cutting swath and faster work on thick grass.
String Specifications
Craftsman trimmers typically accept line diameters ranging from 0.065 inch to 0.095 inch. The owner’s manual lists the exact size for your model. Using a line that is too thick can cause the motor to stall, while a line that is too thin may break prematurely. Always purchase line that matches the recommended diameter and is rated for the type of vegetation you cut.
Tools and Materials Needed
Before you begin, gather the following items so the job proceeds without interruptions:
- Replacement trimmer line (correct diameter and length)
- Protective gloves
- Safety glasses
- Flat‑head screwdriver (for models with a retaining screw)
- Clean rag or brush
- Small container for the old spool (optional)
Having everything at hand reduces the chance of losing small parts and keeps the workspace tidy.
Safety Precautions
Safety should never be an afterthought. Follow these precautions every time you service the trimmer:
- Disconnect the spark plug wire on gas models or remove the battery on cordless units.
- Unplug electric models from the outlet.
- Wear gloves and eye protection to guard against sharp line ends and debris.
- Work on a stable, flat surface away from children and pets.
- Never force components; if something resists, double‑check the release mechanism.
These steps prevent accidental starts and protect you from flying line fragments.
Step‑by‑Step Guide to Changing the String
The following ordered list covers the complete procedure for most Craftsman trimmer heads. Refer to the specific head type notes if your model differs slightly.
- Power off and disconnect. Remove the spark plug wire, battery pack, or unplug the unit. Confirm the motor cannot start.
- Remove the spool. Press the release tabs or unscrew the retaining cap, then pull the spool straight out. Keep any springs or washers in a safe place.
- Clean the head. Use a brush or rag to clear grass clippings, dirt, and old line fragments from the housing and the spool cavity.
- Load new line. Cut a length of line according to the manual (usually 10–15 feet). Insert one end into the anchor hole, wind the line evenly in the direction indicated by arrows on the spool, and leave a short tail for the feed mechanism.
- Reassemble the head. Place the spool back into the housing, re‑engage any springs, and secure the cap or tabs. Ensure the line feeds freely when you pull it.
- Test the trimmer. Reconnect power, start the engine or motor, and tap the head on the ground (for bump‑feed) to verify proper line advancement.
If the line does not feed, double‑check the winding direction and that the line is not crossed over itself.
String Type Comparison Table
| Line Type | Diameter (in) | Best For | Durability | Typical Cost (per 50 ft) |
|---|---|---|---|---|
| Round nylon | 0.065–0.080 | Light grass, edging | Moderate | $4–$6 |
| Twisted (serrated) | 0.080–0.095 | Thick weeds, brush | High | $6–$9 |
| Square/star shaped | 0.080–0.095 | Heavy‑duty commercial use | Very high | $8–$12 |
| Co‑polymer (low‑stretch) | 0.065–0.095 | General purpose, longer life | High | $7–$10 |
Choose the line that matches your typical cutting conditions and the diameter recommended for your model.
Tips for Longer String Life
Extending the usable length of each spool saves money and reduces downtime. Consider these practical habits:
- Keep the cutting height just above the ground; excessive contact with soil wears line quickly.
- Avoid forcing the trimmer through dense, woody stems; use a brush cutter attachment for that work.
- Store the trimmer in a dry place; moisture can make nylon brittle.
- Periodically inspect the line for nicks or fraying and trim the damaged section before it snaps.
- Use the correct line diameter; oversized line creates excess friction and heat.
Implementing these tips can double the interval between line changes.
Common Mistakes and How to Avoid Them
Even experienced users occasionally make errors that lead to poor performance or damage. Here are the most frequent pitfalls:
- Winding the line in the wrong direction. Most spools have arrows; winding opposite to the arrow prevents the bump‑feed from releasing line.
- Over‑filling the spool. Too much line causes binding and can jam the feed mechanism.
- Using mismatched line diameter. A line that is too thick stalls the motor; too thin breaks instantly.
- Neglecting to clean the head. Debris buildup interferes with smooth line release.
- Forgetting to reconnect the spark plug or battery. The trimmer will not start, leading to unnecessary troubleshooting.
Address each mistake by double‑checking the manual, winding carefully, and performing a quick test before full‑scale trimming.
Troubleshooting Common Issues
If the trimmer still behaves oddly after a line change, run through this quick checklist:
- Line does not advance. Verify winding direction, ensure the line is not tangled, and confirm the bump‑feed spring is seated.
- Line breaks immediately. Check for sharp edges on the spool, reduce cutting speed, or switch to a more durable line type.
- Motor overheats. Excessive line drag from over‑filled spool or wrong diameter can cause overheating; reduce line length or use correct size.
- Vibration or noise. Loose spool cap or missing washer; tighten all fasteners to spec.
Most issues resolve with a careful re‑inspection of the spool installation.
Frequently Asked Questions
How often should I change the string?
Frequency depends on usage intensity and vegetation type. For typical residential lawn care, expect to replace the line every 2–4 hours of cutting time. Heavy brush work may require changes every hour.
Can I use any brand of trimmer line?
Yes, as long as the diameter matches the specification in your owner’s manual. Quality varies, so reputable brands tend to last longer and feed more consistently.
Why does my line keep jamming?
Jamming usually results from incorrect winding direction, over‑filling the spool, or debris inside the head. Clean the head thoroughly and rewind following the arrow indicators.
Is it necessary to remove the spool to change line?
On most Craftsman models, yes. Removing the spool gives you full access to the anchor holes and prevents line from crossing over itself during winding.
What is the best line diameter for my model?
Consult the manual; most residential Craftsman trimmers use 0.080 inch line. Using the recommended size ensures optimal motor load and cutting performance.
Conclusion
Mastering How to Change Craftsman Weed Eater String? is a straightforward skill that pays off in smoother operation and lower maintenance costs. By understanding your specific head type, gathering the right tools, observing safety protocols, and following the step‑by‑step process outlined above, you can swap line quickly and get back to a clean‑cut yard. Remember to select the proper line diameter, wind it in the indicated direction, and test the feed before tackling a full job.
