Description
Overview:
The Tensioner for Husqvarna PR15 and PR17 Riders is a genuine Husqvarna OEM component designed to keep drive and deck belts at the correct working tension for reliable mower performance. Built from durable metal with an integrated pulley and bearing, it helps prevent belt slip, reduces wear, and supports smooth power transmission. Supplied to Husqvarna specification under MPN 506993001 (506 99 30-01), it is engineered for Rider-series machines such as the PR15 and PR17. Correct tension helps maintain consistent blade speed and traction, improves cut quality, and extends belt life.
