  Steven HardingAug 3, 2025
  If the line on your GreenWorks Pro Trimmer isn't advancing, here are a few things to check: * **Welded lines:** The lines might be stuck together. Lubricate them with silicone spray. * **Insufficient line:** You may not have enough line on the spool, so install more line. * **Worn lines:** The lines could be too short. Try advancing the cutting line. * **Tangled lines:** The lines might be tangled. Remove them from the spool and rewind them neatly.

  If the line on your GreenWorks Pro Trimmer keeps breaking, it might be due to incorrect usage. Cut with the tip of the line, avoiding stones, walls, and other hard objects. Also, advance the cutting line regularly to maintain a full cutting width.

How to prevent grass from winding around my GreenWorks Pro STB301 head?

  Matthew JacksonAug 16, 2025
  If grass is winding around the trimmer head and motor housing of your GreenWorks Pro Trimmer, it may be because you're cutting tall grass at ground level. Cut tall grass from the top down, removing no more than 8" in each pass to prevent wrapping.

  If you notice a significant increase in vibration with your GreenWorks Pro Trimmer, it could be because the line is worn down on one side and hasn't been advanced in time. Make sure the line on both sides is normal and advance the line.
