Product questions

Answers for this part.

Is this a complete gearbox or a full gearbox rebuild kit?
No. This listing is for the aftermarket gearbox gearset only; it is not a complete gearbox and does not include a full bearing/seal rebuild kit. Bearings, seals, shafts, pulleys, spindle parts, and complete gearbox assemblies are separate items if available for your deck.
Do I need bearings or seals when replacing the gearbox gears?
If the gearbox lost oil, leaked, or locked up, inspect the bearings and seals before installing new gears. A new gearset will not seal the gearbox by itself; any bottom-seal or oil-leak issue needs to be corrected with the proper seal/bearing parts before filling it with oil.
Why does the listing mention 60-inch decks if I have a 72-inch deck?
The title can be confusing because this gearset is listed for multiple Kubota mower-deck families, including both RCK60 and RCK72 models in the fitment list. Go by the exact deck model on your deck tag and the page fitment checker, not just the deck width shown in a search result or title snippet.
What information should I use to identify the correct gearbox gearset?
Use the mower deck model number—the RCK... number on the deck tag—as the main identifier. Tractor model, ROPS model, and tractor serial alone usually are not enough; if you are unsure, send support a photo of the deck tag and any gearbox or part-number markings.
