Tuff Torq 7A646084091 K46AW Transaxle

Restore smooth, familiar tractor drive control with a complete Tuff Torq hydrostatic transaxle. Part 7A646084091 is identified as a K46AW configuration and is supplier-listed as replacing 7A646084090.

K46 is a large product family, not a universal fitment. Even closely related configurations can differ in axle length, input, controls, brake, fan, pulley, mounting, or internal setup.

Why This Matters

A transaxle replacement is a substantial repair. Verifying the full Tuff Torq tag and equipment model/serial range before ordering helps prevent discovering a configuration mismatch after disassembly.

Reference Guidance

7A646084090 is retained as an identification/search aid based on supplier data. Confirm the manufacturer’s current supersession and the exact machine application before ordering.

Installation & Service Notes

• Compare the original tag, axle and control configuration, input pulley/fan, brake, and mounting details.
• Follow Tuff Torq and equipment-manufacturer requirements for oil, belt setup, linkage adjustment, cooling, and purging.
• No equipment-specific installation PDF has been verified for this listing.

Before You Order

Match the complete part/build code and verify the original component, equipment model and serial number, plus all relevant shaft, axle, control, port, brake, rotation, mounting, and revision details. A partial code or similar appearance is not enough to confirm fitment.
