What to do if the cutting head will not advance line on my Troy-Bilt TB635 EC?

  Samantha MontgomeryJul 28, 2025
  If the cutting head on your Troy-Bilt Trimmer won't advance the line, several factors could be responsible. Check if the cutting head is bound with grass and clean it if necessary. Ensure that the cutting head is not out of line, and clean or replace the air filter. Also, inspect the inner reel for binding and clean the inner reel and outer spool. Additionally, check if the cutting head is dirty and clean it. If the line is welded, open the cutting head and remove the welded section. If the line is twisted, rewind it. Finally, 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.
