How to install/replace the grass rope?
Updated on 2026/01/26
GOAT comes with pre-installed trimmer line, requiring no setup for first use.
If the trimmer line runs out, replacement instructions can be found on YouTube or in the manual:
(1) Press and hold the “Start” button on the machine for 5 seconds to lower the cutting head. Then stand the machine upright or flip it over. During flipping, use the original radar lens cover to protect the laser lens.
(2) Remove the screws securing the trimmer line cover;
(3) Pinch the raised tabs at both ends of the trimmer line cover and pull it outward to remove;
(4) Unwind the depleted trimmer line roll. Pull a section of the new trimmer line roll's starter loop through the circular hole, then secure the new trimmer line roll in place;
(5) Replace the trimmer line cover and tighten the screws;
(6) If the exposed trimmer line is too short, use the button on the outer edge of the cover to release more line. Press once to extend a segment;
(7) After replacement, reassemble the machine to its original state.
