The weight class of the Kubota U10-3 sizes the attachment. It does not tell you the pin diameter, the pin spacing or the stick width, and those decide whether an attachment fits. Measure them on the machine, or send us the measurements of the bucket it runs today.
On a mini excavator the weight of the attachment counts for more than on a larger machine, because every kilogram of bucket is taken from lift capacity and stability. A narrow trenching bucket and a wide grading bucket are the usual pair, and many machines run a small quick coupler to change between them.
Quick coupler brackets at this weight
In our model tables, the attachments listed for the Kubota U10-3 at its weight are built with these brackets. Each code opens the models that list it.
Brackets we build attachments with in this weight range. Not a confirmed fit.
- Measure the diameter of both bucket pins.
- Measure the distance between the pin centres.
- Measure the inside width between the stick ears.
- If the machine runs a quick coupler, note its make and type.

What the U10-3 figures mean for its attachments
- Its auxiliary circuit is rated at 21 l/min and 176.5 bar. A breaker, auger, tilt rotator or other hydraulic tool states the oil flow it needs, so choose one whose range includes this figure.
- The main pump delivers up to 21 l/min at 176 bar. That is the pump output of the whole machine, not the flow an attachment gets.
- It digs down to 1,800 mm. That is the deepest trench it can open.
- Kubota lists buckets from 380 to 398 mm wide for this machine.
- Kubota lists a bucket capacity of 0.024 m³.
- Bucket breakout force is 10.4 kN and arm crowd force 5.4 kN. That is the force a bucket or ripper works with at the tooth.
- Kubota gives a lifting capacity of 390 kg. Check a heavy grab or hammer, plus its load, against the full load chart.
- Its transport length is 2,980 mm.
- Its transport height is 2,230 mm.

- A zero tail swing: the rear stays inside the tracks when the upper slews.
- Operator protection certified to ROPS and FOPS.
- Boom swing, for digging along walls and around obstacles.
