Simplicity, Snapper & Massey Ferguson Transmission Replacement: Tuff Torq Lookup
Simplicity, Snapper, Massey Ferguson and other Briggs & Stratton-family tractors use Tuff Torq K46, K57, K62/K66 and K71 transaxles. Find your model below to see the matching Tuff Torq unit.
Same model, two units? Mower makers sometimes changed transaxles partway through a model's production. If your model appears more than once, match the 11-digit Tuff Torq number on the white label on your unit, or send us the label details and we'll confirm.
