What mini excavator replacement parts does Broken Tractor carry for Kubota machines?

We carry undercarriage, hydraulic, engine and structural parts for Kubota mini and midi excavators. That includes track chains, rollers, idlers and sprockets for steel and rubber tracks, hydraulic cylinders, pumps, control valves and hoses, plus filters, gaskets and cooling system parts for Kubota diesel engines. We offer both new OEM-spec parts and used serviceable parts across the KX, U and R series lines.

What are the main excavator parts and their functions?

A Kubota excavator's main part groups are the undercarriage, the hydraulic system, the engine and the structural pieces. Undercarriage parts like track chains, rollers, idlers and sprockets support the machine and drive the tracks, while hydraulic cylinders, pumps, control valves and hoses power the boom, arm and bucket circuits. Engine parts such as filters, gaskets and cooling system components keep the Kubota diesel running.

How do I make sure a part fits my Kubota KX series excavator?

Confirm your machine's serial number range and build date before ordering, because the KX series saw mid-cycle updates that change which parts fit. The safest approach is to match the part number from your old part to the replacement. If you are unsure, call (800) 909-7060 and our parts team can verify fitment for your model and serial number.
