The weight class of the Kubota U48-4 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 U48-4 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 U48-4 figures mean for its attachments
- Its auxiliary circuit is rated at 70 l/min and 206 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 118.8 l/min at 245 bar. That is the pump output of the whole machine, not the flow an attachment gets.
- It digs down to 3,380 mm. That is the deepest trench it can open.
- Kubota lists buckets from 550 to 600 mm wide for this machine.Our sizes in that range: GP - general purpose digging bucket (GP-60); GPO - GP bucket with perforated bottom (GPO-60); GPL - general purpose digging bucket (GPL-60); DS mini - Scandinavian deep digging bucket for mini-excavator (DS-50); CB mini - hydraulic clamp bucket for mini-excavator (CBR-60)
- Kubota lists a bucket capacity of 0.14 m³.
- Bucket breakout force is 33 kN and arm crowd force 22 kN. That is the force a bucket or ripper works with at the tooth.
- For transport it measures 5,330 x 1,960 x 2,550 mm (length, width, height).
