Hustler 604208 Pump Drive Belt – OEM Wheel Drive Belt for Super Z & HyperDrive

Genuine OEM Hydraulic Pump Drive Belt (Wheel Drive)

The Hustler 604208 Pump Drive Belt is a genuine OEM replacement belt engineered to transfer power from the engine to the hydraulic pumps that drive the wheels on Hustler Super Z, Super Z HyperDrive, Super Z HD, and Super SF zero-turn mowers.

This belt was originally designed as a cogged belt and has been superseded by a smooth V-belt design per Hustler engineering updates, providing quieter operation, improved durability, and consistent power transfer under high load conditions.

A worn or stretched pump drive belt can cause loss of ground drive, inconsistent wheel response, vibration, or reduced hydraulic efficiency. Installing the correct OEM Hustler belt restores proper traction and protects pumps, pulleys, and drivetrain components.
