Description
Overview:
This Genuine Stihl Gear Housing (0°, 600 mm) is a factory replacement assembly for selected Stihl long‐reach hedgetrimmers, including the HL94C‐E and HLA135K. Built from a durable metal alloy with a hard‐wearing, corrosion‐resistant finish, it keeps the cutter drive correctly aligned and transfers power smoothly to the blades. The fixed 0° head layout is ideal for straight, accurate trimming, while the 600 mm (23.6 in) length provides extra reach without adding excessive weight. Engineered to Stihl's specifications, it restores performance and reliability when a worn or damaged gear head causes noise, play, or poor cutting. OEM No. 4243 640 0511 ensures the correct fit and function on compatible machines used by professionals and home users alike.
