Pick the system on your machine and we put it in your enquiry. We check the bracket before we send the quote.
How to measure your coupler
Not sure which system it is? Three measurements tell us which bracket you need.
- Measure the diameter of both pins.
- Measure the distance between the pin centres.
- Measure the width between the inside faces of the ears.
If the coupler has a make or type printed on it, send that too.
Before you order: check the interface
The weight class of the Kubota U145 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.
At this weight the choice is mostly about the material. A general purpose bucket suits soil and gravel, a reinforced bucket with thicker wear parts suits mixed ground and broken rock, and the quick coupler on the machine sets the bracket every attachment needs.
Quick coupler brackets at this weight
In our model tables, the attachments listed for the Kubota U145 at its weight are built with these brackets. Each code opens the models that list it.
- 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 U145 figures mean for its attachments
- Its auxiliary circuit is rated at 126 l/min and 343 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 258 l/min at 343 bar. That is the pump output of the whole machine, not the flow an attachment gets.
- It digs down to 5,510 mm. That is the deepest trench it can open.
- Kubota offers arms from 2,500 to 3,010 mm. A longer arm reaches further, a shorter one handles a heavier bucket.
- Kubota lists a 898 mm wide bucket for this machine.
- Kubota lists a bucket capacity of 0.5 m³.
- Bucket breakout force is 90 kN and arm crowd force 62 kN. That is the force a bucket or ripper works with at the tooth.
- For transport it measures 7,350 x 2,490 x 2,940 mm (length, width, height).
