Find string trimmer parts at BlueStars Parts for common cutting, line-feed, fuel, starting, and maintenance repairs. Shop trimmer heads, spool components, carburetor-related parts, mounting hardware, and other replacements by model or part number.
If your string trimmer will not start, the line will not feed, the cutting head vibrates, or trimming performance has dropped, inspect the related component before replacing the entire tool.
Which String Trimmer Part Matches Your Problem?
- Trimmer line will not feed: inspect the spool, cap, trimmer head, eyelets, and internal feed components.
- Bump feed no longer works: worn components inside the trimmer head may require head or spool replacement.
- Trimmer head is cracked or loose: replace a damaged head before continuing operation.
- String trimmer will not start: inspect the carburetor, fuel system, ignition components, air filter, and starter system.
- Engine starts but stalls: check fuel delivery, carburetor condition, airflow, and fuel quality.
- Trimmer vibrates excessively: inspect the cutting head, mounting hardware, shaft connection, and rotating components.

How to Find the Right String Trimmer Replacement Part
- Step 1: Find the model number. Check the side of the motor housing, shaft, or manufacturer identification label.
- Step 2: Find the original part number. Look for numbers molded, stamped, or printed on the trimmer head, spool, carburetor, or other component.
- Step 3: Identify the power type. Confirm whether your trimmer is gas, cordless, or corded electric.
- Step 4: Check cutting-head specifications. Compare thread direction, thread size, head style, and recommended trimmer-line diameter.
- Step 5: Check engine information. Carburetor and fuel-system parts may require the exact engine or carburetor series.
- Step 6: Confirm compatible models. Similar trimmers from the same brand may use different replacement components.
Quick Tip: Do not choose a trimmer head by appearance alone. Thread size, rotation direction, mounting system, and model compatibility must match.
When Should You Replace a String Trimmer Head?
Consider replacing the trimmer head when:
- The line repeatedly jams or will not feed
- The bump-feed mechanism stops working
- The housing is cracked or physically damaged
- The head becomes loose or develops excessive vibration
- The spool or retaining components are badly worn
Can String Trimmer Parts Fit Multiple Brands?
Some replacement trimmer heads, fuel components, and mounting parts can fit multiple models when the thread, mounting system, part number, and specifications match.
Before ordering, compare:
- String trimmer brand and model
- Original part number
- Replacement or cross-reference numbers
- Thread size and direction
- Recommended line diameter
- Engine or carburetor information when applicable
- Compatible model list

String Trimmer Parts FAQs
How do I know which trimmer head fits my string trimmer?
Match the trimmer model and original head number first. Then compare thread size, thread direction, mounting configuration, line diameter, and the compatible model list.
Why does my trimmer line keep getting stuck?
Incorrect winding, debris inside the spool, an overloaded spool, damaged eyelets, or worn feed components can prevent the line from advancing properly.
When should I replace the trimmer head instead of the line?
Replace the head when the housing is cracked, the bump-feed system fails, internal components are badly worn, or correct line installation does not solve repeated feeding problems.
Can I replace a string trimmer head myself?
Many trimmer heads can be replaced by an experienced DIY user. Disconnect the battery or spark plug first, lock the shaft correctly, and confirm the thread direction before removing the old head.
