The Rhinoceros mini excavator line includes several models such as the XN-08, XN10-8, XN12-9, XN-18, and XN20. Ranging from 800kg to multiple tonnes, there is a model suitable for a wide range of applications such as personal work (landscaping, residential work, farming, etc.) to more heavy-duty professional work (such as deeper trenching, foundation work, large-scale earth moving, etc.).
Main Considerations Before Choosing a Model
Weight:
The model numbers represent the weight of the machines. For example, the XN08 is approximately 800kg, while the XN20 is 2 tonnes. There are both advantages and disadvantages of having a heavier mini excavator.
Advantages:
- Increased breakout force – Heavier machines benefit from both increased weight and more hydraulic power, allowing for deeper and more efficient digging, as well as improved ability to break through hard rock.
- Stability and traction – Reduces the risk of tipping over or slipping when working on uneven or soft terrain.
- Improved lifting capacity – Allows you to handle heavier loads without compromising performance or tipping over.
Disadvantages
- Reduced manoeuvrability – Heavier mini excavators can be harder to navigate in tight spaces.
- Higher costs – Increased costs to transport the mini excavator, as a special trailer may be required. There are also increased fuel consumption costs during usage, as more weight means more fuel is needed to move the machine.
- More ground pressure – The added weight can damage delicate surfaces like lawns.
Engine
The engine type varies between the models, affecting performance and cost.
- The XN08 and XN10-8 use single-cylinder Koop engines. These engines are cost-effective and produce a surprising amount of power. Without complicated electronics, they are also easier to maintain. These are great for small projects and occasional work.
- The XN12-9, XN18, and XN20 use triple-cylinder Japanese Kubota engines. These provide more power, smoother operation and reduced operational noise. They also can run twin hydraulic pumps. The triple-cylinder engines are more suitable for daily professional use.
To see the exact engine specifications for each machine, please review the technical specifications on the mini diggers’ individual page.
Attachments
Mini excavator attachments typically come in two main pin diameters: 25mm and 30mm.
- The XN08, XN10-8, and XN12-9 use 25mm attachments. These are more common and often slightly cheaper
- The XN18 and XN20 use 30mm attachments. These are more robust and better suited for heavier-duty tasks.
The attachments bought for each excavator will significantly impact the range of projects your mini excavator can handle. For example, an auger will enable a mini-excavator to drill holes in the ground. Attachments can be found here.
Choosing the Right Model
Rhinoceros XN08
This is the least expensive and lightest model. Its low weight is a key advantage of this model, allowing it to be towed on standard trailers and be transported easily. The low weight also means it has a low fuel consumption cost on top of the already highly accessible price. The XN08 is also quite small, and with the retractable tracks option, they are even capable of fitting through some personnel doors.
The XN08 is powerful in small-scale landscaping, soil digging and gardening. These are perfect for individuals wanting a compact and budget-friendly mini digger for personal projects.
Rhinoceros XN10-8
While slightly heavier, the XN10-8 isn’t significantly stronger than the XN08. However, the XN10-8’s engine access is more convenient, and it has side hydraulic controls rather than front-mounted controls, which gives the operator better ergonomics and control.
It maintains a compact size and low weight, making it unlikely to cause significant ground damage to delicate surfaces such as lawns.
Rhinoceros XN12-9
With its triple-cylinder Kubota engine, the XN12-9 is more flexible and is the ideal excavator for medium-scale projects including trenching, small foundation work, utility digging, driveways, stump removal, material handling and more. It is much more powerful, efficient and smooth in operation – making it better for frequent or professional usage.
The XN12-9, 18 and 20 also all come with swing booms and extensible/retractable tracks, making them more versatile against walls, in trenches and more. The heavier weight also makes them more stable for varied terrain conditions.

Rhinoceros XN18
This is a step up from the XN12-9 with a more powerful engine and hydraulic power. Its significantly higher weight and breakout force makes it superior for large-scale digging and excavation work. However, this also makes it more difficult to transport, have higher fuel costs, and risky to use on delicate ground.
It is great for professional use in heavy-duty work giving smooth, efficient excavation within the bounds of mini diggers. It has the same uses as the XN20 but at a slightly lower cost and weight.
Rhinoceros XN20
The XN20 is perfect for large-scale and heavy-duty work within the bounds of mini excavators such as large-scale earthmoving and most excavation work within a residential or urban setting. It gives a balance of compact design and greater digging force.
Final Thoughts
The best Rhinoceros mini excavator for you depends on your project requirements:
- Choose the XN08 for small personal projects and budget-friendly landscaping.
- Choose the XN10-8 for improved ergonomics and control.
- Choose the XN12-9 for medium-scale projects with increased efficiency and flexibility.
- Choose the XN18 for professional large-scale projects and heavy-duty excavation at a slightly lower cost and weight.
- Choose the XN20 for professional large-scale projects and heavy-duty excavation.
If you wish to work on full single or multi-story construction, then a full-sized excavator would be more suitable for you. Read more about the differences between mini excavators and standard excavators here.
It’s a good idea to review the technical specifications listed under each excavator model to see if they suit your requirements. The attachments will also affect if the mini diggers can meet your requirements.
