Important Notes

• Verify part number 539120772 before ordering
• Confirm compatibility with your specific Husqvarna equipment model and hydrostatic drive configuration
• This component is identified as an EZT Hydro; verify the exact transmission application and required configuration before ordering
• The exact manufacturer, transmission model, displacement, gear ratio, input specifications, axle dimensions, shaft configuration, mounting pattern, fluid specification, and operating capacity are not identified in the supplied product information
• Verify whether the application requires a specific left-hand or right-hand transmission configuration before ordering
• Compare the original hydro unit’s housing configuration, mounting points, input shaft, axle or output arrangement, control linkage connections, bypass mechanism, and adjoining drive interfaces
• Do not substitute a hydrostatic transmission component based solely on approximate dimensions, appearance, or equipment type
• Inspect associated drive belts, pulleys, cooling fans, control linkages, bypass components, axles, hubs, brackets, seals, and mounting hardware for wear or damage
• Check the surrounding drive system for fluid leakage, damaged seals, worn belts, loose pulleys, restricted linkage movement, damaged cooling components, or excessive contamination
• Reduced drive performance may also be caused by drive belts, control linkage, pulleys, adjustment issues, or other transmission-system components; properly diagnose the drive system before replacing the hydro unit
• Keep the hydrostatic transmission and cooling areas clean and free from excessive grass, dirt, and debris that could restrict cooling
• Follow the equipment and transmission manufacturer’s applicable procedures for installation, adjustment, fluid service, purging, and initial operation
• If the hydrostatic system is opened or serviced, verify the correct fluid type, fluid level, and purging procedure for the specific transmission before operation
• This listing is for the EZT hydro component; do not assume that drive belts, pulleys, cooling fans, hubs, control linkage, brackets, fluid, fittings, fasteners, or additional transmission components are included unless specifically stated
• Shut off the engine, remove the ignition key, allow all moving components to completely stop, and properly secure the equipment before servicing the transmission
• Properly support the equipment if wheels, axles, or drive-system components must be removed during installation
• After installation, verify proper mounting security, linkage adjustment, belt alignment, drive engagement, forward and reverse operation, braking interaction, fluid integrity, and overall equipment mobility before returning the equipment to normal service
