    What to do if the cutting head will not advance line on Troy-Bilt TB22 EC Trimmer?
    • J
      Jacob PatelJul 25, 2025
      If the cutting head of your Troy-Bilt Trimmer will not advance line, it could be due to several reasons. Check if the cutting head is bound with grass and clean it if necessary. Also, the cutting head could be out of line, so clean and thoroughly dry it. An inner reel bound up may also cause this issue, so clean the inner reel and outer spool. Additionally, if the cutting head is dirty, stop the engine and clean the cutting head. If the line is welded, open the cutting head and remove the welded section. If the line is twisted, rewind it. Lastly, if not enough line is extended, stop the unit, push the bump knob, and pull the line until 4 inches (102 mm) is outside of the cutting head.

    Why does my Troy-Bilt Trimmer engine lack power?
    • M
      Ms. Sherry ThomasJul 31, 2025
      If your Troy-Bilt Trimmer engine lacks power or stalls, the issue might stem from old or improperly mixed fuel. In this case, drain the fuel tank and add fresh, properly-mixed fuel. A dirty air filter can also cause this problem, so clean or replace it. Lastly, a fouled spark plug can lead to power loss, so consider replacing it.
