Description
Overview:
The Spring for Chassis on Husqvarna ride-on mowers (MPN 506 83 43-01) is a genuine Husqvarna replacement designed to support and stabilise the mower chassis. Made from high‐grade steel, this coil spring maintains correct tension within the chassis assembly so the machine runs smoothly and components stay aligned under load. Built to original equipment specifications for a direct fit, it restores performance when the original spring has weakened or failed. Suitable for a wide range of Husqvarna Rider machines, including the P520 D Rider and P525 D Rider, it helps reduce vibration and protects surrounding parts from premature wear. Use this part to keep your mower operating reliably across regular domestic and professional mowing tasks.
