Parts Compatible with the Kubota KX151 Mini Excavator

The KX151 is the 4.5 ton class entry in Kubota's original K Series mini excavator family, produced through the late 1990s as the upper-mid machine between the KX121 and KX161. The KX151 uses the V1505 era 4-cylinder mechanical injection diesel engine and direct-drive hydraulic main pump, the same engine family that powers the KX101 and KX121-2 / KX161-2 siblings. Customers commonly find KX151 machines still in service in landscaping and small-contractor applications.

The KX151 shares many service parts with the KX101, KX121-2, and KX161-2 (the other V1505-era K Series mini excavator siblings) because Kubota engineered the original 4-cylinder K Series on a shared parts platform.
