Emissions and DEF

Genuine Kubota aftertreatment and emissions components for Tier 4 engines: diesel particulate filters and DPF service kits, catalysts and catalytic converters, exhaust mixers, EGR valves, and DEF tanks, brackets and sensors.

Emissions hardware is tied to the engine’s certified configuration, which means substituting or deleting components affects the engine’s compliance status as well as how the ECU runs it. These parts are also frequently updated by Kubota through service campaigns, so an older number may have been superseded more than once. If your part number does not appear here, send it to us with the engine serial number and we will trace it to the current component.
