The U55-4 is a Kubota mini excavator.
The KX057-4 shares most of the same parts. The KX121-3 shares many of the same parts. Match the model and serial number on the serial plate before ordering, since parts can change between serial ranges and options.
Common replacements include the primary air filter that replaces OEM HWR1T42270, the engine oil filter that replaces OEM RD15951940, and the suc filter that replaces OEM RD451-62210. Fluid and fuel caps, switches and gaskets make up much of the rest of the range.
