Tuff Torq 787Q0624232 TZT13GR Integrated Hydrostatic Transaxle

A zero-turn transmission is defined by its complete configuration, not simply by the family stamped on the housing. This Tuff Torq assembly is sold as part 787Q0624232 and is supplier-identified with the TZT13GR family.

Confirm the full number from the original transmission and the mower model and serial number. Control orientation, shafts, brake arrangement, ports, and mounting details can vary within the same family.

Why this matters

• Exact-number selection reduces the chance of a left/right or control-configuration mismatch.
• A complete replacement can avoid combining new parts with unknown hydraulic wear.
• Clear reference labeling helps without overstating interchangeability.
