The spool does not turn when the motor is running
For model number 123L
Hi Mark, thank you for reaching out. The issue might be with the drive shaft, part number PS9029500. The drive shaft connects the engine to the trimmer head. If it's broken or has come loose from either end, the head won't spin. You may need to replace it to fix the issue. We hope this solves your problem!
