A top-selling compact excavator. Reliable, but rubber-track life and hydraulic drift still decide the price — and rental hours run hard.
Kubota's compact excavators are a benchmark for reliability in the size class, so the inspection is about confirming the wear items are in good shape rather than catching frequent failures. Rubber tracks and the hydraulic system are the main cost centers.
Tracks wear, crack, and delaminate; the undercarriage wears underneath.
CHECK Measure track life and inspect for cracks and roller wear.
Worn cylinders and valves let functions drift.
CHECK Hold a load for drift and test auxiliary circuits.
Swing bearing and swivel wear with use.
CHECK Check swing play and inspect the swivel.
Cylinders and pins wear.
CHECK Inspect cylinders for leaks and check pin play.
Kubota diesels are durable but maintenance matters.
CHECK Check blowby and sample oil.
