Woodruff keys fit into a matching keyway on both the shaft and the mating hub, preventing relative rotation between the two parts during operation. This style of key is commonly found in lawn and garden equipment drivetrains, including blade engagement systems and engine-to-deck connections. Installation and replacement are typically performed by small-engine technicians and outdoor power equipment service professionals.\u003c\/p\u003e\u003cp\u003eThis part is suited for lawn and garden applications where a Woodruff-style keyed shaft connection is specified. It is used as a service replacement when an original key is sheared, worn, or lost during routine maintenance or blade impact events. Sheared Woodruff keys are one of the most common results of blade strike damage and are a standard item in drivetrain service procedures for walk-behind and riding mowers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWoodruff key profile for positive shaft-to-hub torque transfer\u003c\/li\u003e\n\u003cli\u003eNo. 6 size designation for precise keyway fitment\u003c\/li\u003e\n\u003cli\u003eDirect OEM replacement part for HUSQVARNA lawn and garden equipment\u003c\/li\u003e\n\u003cli\u003eCommonly replaced after blade strike or impact events\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement Woodruff key for HUSQVARNA lawn and garden power equipment where a No. 6 Woodruff key is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified small-engine or outdoor power equipment technician.
