| Consideration | QS-12 | QS-15 |
|---|---|---|
| Access | Compact footprint | Check width and tail swing |
| Digging | Light landscaping and trenches | More working capability |
| Stability | Good for light work | More stable platform |
| Attachments | Light bucket and auger | Broader attachment range |

Mini Digger vs Mini Excavator
The terms are often used interchangeably. For Qisheng, the focus is the machine class, application, access and attachment capability.
Access and Stability
QS-12 can work in tighter spaces, while QS-15 provides more stability for heavier buckets and attachments.
Digging Depth and Reach
Confirm the exact specification for the QS-12 and QS-15. Larger class does not always mean the same dig depth across every configuration.
Attachment Compatibility
Check hydraulic flow, mounting and attachment weight. Breakers and augers require a compatible auxiliary circuit.
How to Choose
Choose QS-12 for tight landscaping and garden work. Choose QS-15 when productivity, reach and stability justify a larger machine.
Buying and Delivery Checklist
Before you order a mini digger, confirm access width, operating weight, digging depth, lifting capacity, transport limits and the attachments required for the main job.
Ask for a line-item quotation covering the machine configuration, attachment package, hoses, couplers, spare parts, packing, freight, insurance and destination charges.
Confirm warranty terms, parts availability, production time, inspection procedure, shipping documents and after-sales technical support before making a deposit.
