Description
Overview:
This Woodruff Key is a semi‐circular steel shaft key used to lock rotating components to a shaft and prevent slippage. It is suitable for Husqvarna disc cutters, including 268K and 272K, and other compatible Husqvarna machines. The key sits in the shaft keyway to maintain correct alignment between the shaft and the flywheel, pulley, or gear, helping to preserve ignition timing and drive integrity under load. Made from durable steel for dependable service in site conditions, it is a direct replacement part identified by MPN 735880600 (also referenced as 735 88 06-00). Use it to restore reliable operation after a sheared or worn key, or during routine rebuilds and preventative maintenance of your cutter's engine and drive system.
