Mower makers sometimes switch transaxles mid-production, so serial number matters. Not on the list? Send us your model and serial and we'll check.

Make sure it fits

Every Tuff Torq unit has an ID label on the case showing the model (like K46DV) and the 11-digit part number. Match 7A646084631 to that label, or to the OEM number in your mower's parts list. Can't read the label? See How to find your Tuff Torq part number, or send us a photo through the Part Finder and we'll confirm the match before you buy.
