Grass trimmer line

Remove the Straw head, which has a place for winding the nylon line, fold the trimmer line in half, in the place of winding the line, thread the line through the slot on both sides.

The length of the trimmer line should not be too long, 10-15cm is appropriate. When installing the line, a knot should be tied on the shaft or the strimmer head and the nylon line should be drawn out from the opposite direction. Otherwise, the line will come off in the process of cutting, and the length of the line at both ends should be the same, otherwise the trimmer will wobble due to imbalance. Trimmer lines are only suitable for young grass, for tall or thick grass,  a cutting blade is much better.
