Heavy-Duty Hydro Pump Drive Belt for 48-Inch Mowers SKU: 461-0010-00

When your hydro pump belt starts slipping or squealing, you lose drive power just when you need it most—during heavy cutting or on slopes. A worn belt means inconsistent ground speed, poor responsiveness, and eventually total drive failure that leaves you stranded. This heavy-duty replacement restores the positive power transfer your hydrostatic system depends on.

Why This Belt Matters

• Heavy-duty construction resists stretching and heat buildup under load
• Precise dimensions ensure proper pump engagement and drive response
• Built to handle the constant tension demands of hydrostatic power transfer
• Genuine Spartan Parts quality for reliable long-term service

Before installation, clean debris from all pulleys and check for worn bearing surfaces that could damage the new belt. Route according to your mower's drive diagram and verify proper tension after a brief test run—too loose causes slipping, too tight creates premature wear.
