Husqvarna 585813701 Replacement Pulley

Product Description

The HUSQVARNA 585813701 is a replacement pulley designed for use in the drive and blade engagement systems found on Husqvarna zero-turn riding mowers. Pulleys transfer rotational force between belts and spindles or deck components, maintaining proper belt tension and power transfer to the cutting deck. This pulley measures 5.35 x 5.1 x 3.3 inches and weighs 1 pound, making it a direct-fit component for technicians performing deck rebuilds or drivetrain service on compatible Husqvarna mower models.

This pulley fits a range of Husqvarna zero-turn mowers used in residential and light commercial applications. It is a commonly replaced wear item during seasonal maintenance or after belt failure causes pulley damage. Compatible models include the Z448, MZ5424S, Z454, MZ54, MZ52, MZ48, and MZ5424SR. Outdoor power equipment technicians and experienced DIYers familiar with zero-turn deck service will find this a straightforward OEM-specification replacement.
