The weight class of the Develon DX55R-7 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 Develon DX55R-7 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 DX55R-7 figures mean for its attachments
- The main pump delivers up to 138.6 l/min at 274.59 bar. That is the pump output of the whole machine, not the flow an attachment gets.
- Develon lists this quick coupler for it: hydraulic quick coupler QC45. The bracket on every attachment has to match the coupler.
- It digs down to 3,930 mm. That is the deepest trench it can open.
- Its maximum reach is 6,250 mm.
- It dumps at up to 4,135 mm, so a truck or skip side has to sit below that height.
- Develon offers arms from 1,600 to 1,900 mm. A longer arm reaches further, a shorter one handles a heavier bucket.
- Develon lists buckets from 450 to 900 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); RGPL - skeleton rod GPL bucket (RGPL-60); GPLO - GPL bucket with perforated bottom (GPLO-60); SGPL - heavy duty skeleton GPL bucket for mini-excavator (SGPL-60); PDP mini - skeleton BDP stone bucket (PDP-60); DS mini - Scandinavian deep digging bucket for mini-excavator (DS-60); KS mini - cable bucket for mini-excavator (KS-100); CB mini - hydraulic clamp bucket for mini-excavator (CBR-60)
- Develon lists bucket capacities from 0.11 to 0.25 m³.
- Develon gives a lifting capacity of 1,460 kg. Check a heavy grab or hammer, plus its load, against the full load chart.
- For transport it measures 5,400 x 1,980 x 2,575 mm (length, width, height).
- Engine power is 36.4 kW.
