The weight class of the JCB 370X 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.
Heavy excavators dig rock, load trucks and work in quarries, so wear decides the bucket as much as capacity does. Rock and reinforced buckets carry thicker wear steel, teeth and side cutters, and the bucket is sized to the trucks it loads and to the density of the material.DBS - engineered rock bucket for excavator
Quick coupler brackets at this weight
In our model tables, the attachments listed for the JCB 370X 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 370X figures mean for its attachments
- The main pump delivers up to 604 l/min at 350 bar. That is the pump output of the whole machine, not the flow an attachment gets.
- JCB lists this quick coupler for it: Hydraulic Quickhitch. The bracket on every attachment has to match the coupler.
- It digs down to 8,360 mm. That is the deepest trench it can open.
- Its maximum reach is 11,875 mm.
- It dumps at up to 7,275 mm, so a truck or skip side has to sit below that height.
- JCB offers arms from 2,630 to 4,030 mm. A longer arm reaches further, a shorter one handles a heavier bucket.
- JCB lists a bucket capacity of 2.34 m³.
- Bucket breakout force is 249.4 kN and arm crowd force 222.1 kN. That is the force a bucket or ripper works with at the tooth.
- JCB gives a lifting capacity of 9,074 kg. Check a heavy grab or hammer, plus its load, against the full load chart.
- For transport it measures 11,224 x 3,200 x 3,462 mm (length, width, height).
- Engine power is 240 kW.

Questions about the 370X
- What bucket size fits the 370X?
- JCB lists a bucket capacity of 2.34 m³ for it.
- Which quick coupler is installed on your 370X?
- JCB names no coupler system for it, so we cannot know which coupler your machine carries until you tell us. The attachments we list for the 370X are built with these brackets: S80, MS25, CW45, OQ80, SW48, SW66. Pick your coupler above or send us a photo of its nameplate, and we check the bracket before we quote.
