Description
Overview:
This Genuine Husqvarna idler pulley (part number 583 51 21-01) is a flat-profile pulley used to guide and maintain tension in belt-driven systems on garden and light machinery. Built from robust steel with a smooth running surface and an integrated sealed bearing, it helps keep the belt aligned, reduces slip, and ensures consistent power transfer. The pulley measures 2 1/4 inches (5.7 cm) in diameter, making it well suited to compact drive layouts typically found on lawn tractors and ride-on mowers. As an OEM component, it matches the original specification for fit and function, supporting reliable operation and helping to extend belt life when the original idler becomes worn or noisy. Designed for straightforward replacement in the factory mounting position.
