As opposed to bump feed and twist feed systems that use spooled trimmer line, the STIHL Duro-Cut line head has a fixed-head design. It is the ideal trimmer head if you prefer manual heads which require precut lengths of nylon line. Even when operating in severe applications, changing trimmer line is fast and easy—offering you ease-of-use, durability, and longevity.
This is a Genuine Stihl 40-4 Duro-cut head. This head has placement for 4 strings which makes it only fit the Stihl brushcutters.
Model Fit:
FS310, FS350, FS360, FS450, FS460, FS550, FS560
