Description
4229 768 0300 STIHL Shredder Blade – Genuine OEM Fan Wheel Part
The STIHL Shredder Blade (4229 768 0300) is a genuine OEM cutting component designed for use in STIHL shredder vac units. This blade mounts to the fan wheel assembly and is responsible for shredding collected debris into fine mulch during vacuum operation.
Over time, shredder blades can become dull, bent, chipped, or worn due to contact with sticks, gravel, and heavy debris. A damaged blade may reduce shredding efficiency, cause vibration, or affect overall vacuum performance. Replacing it with the correct OEM part restores proper mulching performance without replacing the entire fan wheel assembly.
Manufactured to STIHL factory specifications, this genuine shredder blade ensures precise fitment, proper balance, and long-term durability under demanding operating conditions.
