Description
Overview:
This genuine Husqvarna spring (MPN 506 94 63 01) is a durable, tempered spring‐steel component used across Husqvarna Rider and professional front‐mower platforms. It provides controlled tension and return action for belt idlers, linkages and operator controls, helping to keep drive and cutting systems working smoothly. The robust steel coil with hooked ends delivers repeatable performance under vibration and load, making it suitable for routine maintenance or like‐for‐like replacement of a fatigued spring. Designed to meet OEM specifications, it restores the correct engagement and return force without modification. Ideal for Husqvarna ride‐on machines used in domestic and commercial settings, including models such as P524 and PR15.
