Description
Overview:
This Genuine Husqvarna spring (OEM Part No. 506 53 56-03, MPN 506535603) is a precision coil made from high‐tensile spring steel for long service life. It restores correct force in mower mechanisms, helping linkages, belt tensioners and deck engagement parts return smoothly to their neutral positions. Designed for Husqvarna front‐rider lawn tractors and professional riders, it fits popular machines such as RIDER 11 and RIDER 13 along with many others in the Rider, R, P, PR and Proflex ranges. Built to Husqvarna's original specification for fit and rate, this replacement part is ideal when an existing spring has lost tension, become deformed or broken, ensuring reliable operation of your machine's cutting or drive system without modifying surrounding components.
Key Features:
- Genuine Husqvarna OEM part for assured compatibility and reliability
- High‐tensile spring steel construction for strength and durability
- Restores correct tension to belt, deck and linkage mechanisms

- Supports smooth cutting and manoeuvring by maintaining proper return action
Typical Applications:

Typical locations include idler arms, deck lift assemblies and engagement linkages on Husqvarna Rider and professional front‐mower platforms in domestic, commercial and grounds‐care settings.
