About this replacement part

This aftermarket gearbox rebuild kit is for the mower deck gear box system on compatible Kubota equipment. It is used when servicing the deck gearbox so the drive components can transfer power properly to the mower blades.

Built to match OEM

This kit is made as a direct aftermarket replacement to match the original gearbox service parts in form and function. The parts are intended to fit the existing gearbox housing and mating surfaces without changing the deck assembly.

Installation

Installation requires removing and opening the deck gearbox, inspecting the housing, and reassembling the unit to the service manual procedure. Common hand tools are typically needed, and a puller or press may be required depending on the parts being replaced; no modifications to the mower deck are intended.

Aftermarket replacement part. Not affiliated with or endorsed by an original equipment manufacturer. Verify the listed part number, model, dimensions, and serial notes before ordering.
