Tuff Torq 7A705124070 K91H 4WS

Four-wheel-steer drivetrains depend on more than the basic transaxle family name. Tuff Torq part 7A705124070 is identified as a K91H 4WS configuration for machines that originally use this exact assembly.

The 4WS designation is a meaningful fitment detail. Steering layout, controls, mounting, and shaft arrangements must all agree with the original machine before installation.

Why this matters

• The exact K91H 4WS identity separates this unit from other K91 configurations.
• Part-number matching protects against costly steering and mounting incompatibilities.
• A complete identified assembly gives the technician a sound basis for service planning.
