Important Fitment Note: “F2803” is an engine designation, not a single tractor model. The original “T233” identifier is not verified as a Kubota tractor; do not claim fitment without an original starter number. Verify 12V, 11-tooth count if applicable, rotation, mounting ear spacing and serial number.

Product Overview

The starter engages the engine flywheel to crank the diesel engine during starting. It is a complete starter assembly rather than an ignition switch or replacement battery cable.

A failing starter can click, crank slowly or stop engaging the flywheel. Before replacing it, also check the battery, grounds and start-relay circuit so an electrical supply problem is not mistaken for a bad starter.

Key Features & Performance

Replaces / Cross-References

Part number reference: 91-29-5308 / 91295310 (supplier reference); compare Kubota 17121-63013 / 17121-63014 only after matching starter specs.

The 91-29-5308 reference comes from the original seller; a Kubota F2803 starter specialist lists Kubota 17121-63013/63014 and Denso 228000-4740/4741 for a specific 12V 2.0kW 11-tooth configuration. Do not treat those as confirmed interchange without physically matching the supplied starter.

Installation & Fitment Notes

Before installation, compare the new part with the original and check that the mounting locations, clearances and supplied hardware match. Follow the vehicle or equipment manufacturer’s installation instructions.
