The AutoCut C head has an on-board line storage spool and the line is fed while the machine is running. This is done by tapping the end of the spool on the ground, which momentarily releases the locking mechanism allowing centrifugal force to advance a measured length of line. Excess line is trimmed by the guard mounted cutter.
With the AutoCut C, mowing line replacement is an especially fast and simple procedure. It is neither necessary to open the mowing head for refilling nor is it necessary to prepare equal lengths of mowing line.FITS STIHL: FS 44,55,56,70,80,85,90,100. KM 55,56,85,90,110,130, +FS-KM
