Hello haydee,

Thank you for your feedback. We are sorry to hear of the of the trouble you are experiencing with the trimmer line. Trimmer line usually breaks because of line crowding. This occurs when the trimmer head is held too close to hard objects that can break the line such as brick, cement, rocks, or fencing. Keeping the line at full extension, and not crowding it, reduces line breakage problems. We suggest cutting with the bare tip of the line because this is the section which moves at the highest speed. Don't let it hit into grass. Ease the line into vegetation, bit by bit from the edge. Line can also get wrapped around thick vegetation and become tangled, breaking the line. Listen to the sound of the machine and when the line slows down; back off out of the grass. If you are still finding the line is breaking or difficult to wind, we would like to hear from you and further troubleshoot the issues you are experiencing. We can be reached at 1-888-909-6757 (1-888-90WORKS) or by email on info@greenworkstools.com.
