Description
Overview:
This genuine Husqvarna spring (MPN 531205831 / 531 20 58-31) is an OEM replacement for selected commercial walk-behind lawn mowers. Made from tempered spring steel, it delivers consistent elasticity and long service life under regular use. The spring maintains correct tension in mower mechanisms, helping controls engage positively and the machine run smoothly and efficiently. It is designed for Husqvarna models such as the R150 S and R150 SH, along with several LC-series variants used by contractors, grounds teams, and homeowners. The robust coiled design withstands repeated cycling and vibration typical of mowing tasks, offering a precise, direct-fit solution that matches original specification. Replacing a fatigued or broken spring restores reliable operation and helps prevent secondary wear on connected components.

Typical Applications:
Used on compatible Husqvarna walk-behind mowers to provide the correct tension in control or tensioning assemblies. Suitable when engagement feels weak, controls do not return as expected, or mechanisms slip due to spring fatigue. Ideal for routine maintenance and preventive replacement to keep commercial and domestic mowing equipment working reliably across the season.
