The weight class of the Hitachi ZX250/300/350-7 SLF 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.
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

What the ZX250/300/350-7 SLF figures mean for its attachments
- Its auxiliary circuit delivers 30 l/min. 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 448 l/min at 343 bar. That is the pump output of the whole machine, not the flow an attachment gets.
- It digs down to 10,870 mm. That is the deepest trench it can open.
- Its maximum reach is 14,950 mm.
- It dumps at up to 11,800 mm, so a truck or skip side has to sit below that height.
- Its arm is 5,930 mm long.
- Hitachi lists buckets from 720 to 1,030 mm wide for this machine.Our sizes in that range: DB - heavy duty digging bucket (DB-300); DBF - flat-top digging bucket for quick coupler (DBF-300)
- Hitachi lists bucket capacities from 0.4 to 0.66 m³.
- Bucket breakout force is 78 kN and arm crowd force 69 kN. That is the force a bucket or ripper works with at the tooth.
- Hitachi gives a lifting capacity of 2,320 kg. Check a heavy grab or hammer, plus its load, against the full load chart.
- For transport it measures 12,870 x 3,190 x 3,140 mm (length, width, height).
