Description
Overview:
This genuine Husqvarna spring (MPN 503 81 60-01) is a small, high-tensile steel component used to maintain correct tension within key mechanisms on Husqvarna brushcutters and trimmers. It helps parts return to position and stay engaged under load, supporting smooth starting, reliable throttle or control response, and consistent cutting performance. Built for repeated flexing, the spring is suitable for a wide range of lightweight to professional machines, including the Husqvarna 223R and 322R. If your machine shows weak return action, inconsistent engagement, or loss of tension in relevant linkages, replacing a worn spring with this genuine part restores proper function and helps protect nearby components from undue wear during regular garden and grounds maintenance.
Key Features:
- Genuine Husqvarna part for assured fit and performance
- Durable spring-steel construction for long service life

- Helps restore smooth starting and control operation

Typical Applications:
Used in the tensioning or return function of control and drive-related mechanisms on Husqvarna brushcutters and trimmers. Ideal when the machine shows weak return action, uneven engagement, or reduced responsiveness during grass trimming, edging, bramble clearing, verge work, and general grounds maintenance. Suitable for both domestic users and professionals who need dependable performance.
