Hydro-Gear ZK-KHEF-SKKC-2PLX Hydrostatic Transaxle

This is a configuration-specific Hydro-Gear transaxle, not a generic replacement chosen from its shape. Part ZK-KHEF-SKKC-2PLX is intended for equipment positively matched to this complete Hydro-Gear number.

The supplier record references two earlier numbers. Those references are useful for research, but they should be confirmed against current manufacturer or equipment documentation before purchase.

Why this matters

• The complete build code captures details that the broader transaxle family cannot.
• Exact matching protects against differences in controls, shafts, brake, ports, and mounting.
• Clearly labeled reference numbers aid the search without promising unsupported interchangeability.

Verified identification

Official Hydro-Gear resources

• Hydro-Gear support — manufacturer support and service-document lookup.

Document note: No exact installation PDF was verified for this full configuration. Use the mower manufacturer’s model- and serial-specific installation procedure.

Ordering, lead time, returns, and warranty

• Match the complete identification number on the original unit; similar configurations may not interchange.
• Many HydroDrives-supplied units are built to order and may require approximately 10–15 business days before shipment.
• Approved returns may incur a 20% restocking fee; original and return shipping charges are nonrefundable.
• Build-to-order, installed, used, damaged, or fluid-filled components may be ineligible for return.
• Applicable warranty coverage may require authorized-service-center installation. Retain service records.

Orders may ship directly from a U.S. partner warehouse. Availability and timing are subject to supplier confirmation.
