Choosing the right excavator to fit the needs of your project can be tricky. Two of the most popular 8T excavators in the market today are the Yanmar ViO80 and the Kubota KX080-3S. Both are reliable, high-performance machines that can deliver great results on site, but their feature sets differ slightly. We put both excavators head-to-head and break down the details in a comparison.
Power and performance comparison – Yanmar vs Kubota
Both the Yanmar ViO80 and the Kubota KX080-3S pack excellent power, but each have different strong-suits.
- Yanmar ViO80: This excavator is powered by a 56-horsepower engine. It’s designed for smooth, controlled operation handling a range of tasks, from digging to lifting. The ViO80’s compact design helps it work in tighter spaces without sacrificing performance, making it ideal for job sites in built-up areas that lack space.

Digging and lifting capacity – Yanmar ViO80 vs Kubota KX080-3S
When it comes to digging and lifting, both machines are equipped for the most demanding projects. Look closer and you’ll see how they differ.
- Yanmar ViO80: The Yanmar ViO80 is well known for its impressive lifting capacity and digging depth. It offers a maximum digging depth of 5.9 metres and a bucket breakout force of 61.5 kN. This makes it suitable for large excavation tasks, such as heavy lifting.
A
- Kubota KX080-3S: The Kubota KX080-3S offers a similar maximum digging depth of 5.8 metres, and a slightly higher bucket breakout force of 64.4 kN, making it a bit more powerful when it comes to digging into tough material. Its lifting capacity is also respectable compared to others in its class.
A
Verdict: Both machines are highly capable in terms of digging and lifting. The Kubota has a slight advantage in breakout force, but the Yanmar edges out with a lower digging depth.

Comparison of Yanmar ViO80 vs Kubota KX080-3S excavators’ manoeuvrability and size
Manoeuvrability is often a deciding factor, especially for jobs in cramped spaces or urban environments.
- Yanmar ViO80: One of the standout features of the ViO80 is its zero-tail swing design. This means that the machine’s body doesn’t extend past its tracks when turning, allowing it to work in tight spaces without the risk of damaging surrounding objects. This makes it a top choice for projects with limited space.
A
- Kubota KX080-3S: The Kubota features a short tail swing design, which offers excellent manoeuvrability without sacrificing stability. While it does have a slightly larger rear radius compared to the Yanmar, it still performs well in tight spaces and urban environments.
A
Verdict: The Yanmar ViO80 is more manoeuvrable especially in confined spaces, thanks to its zero-tail swing. However, the Kubota KX080-3S also offers strong manoeuvrability with its short tail swing design.

Maintenance and durability of the Yanmar and Kubota
Both machines are designed with durability in mind, ensuring continued performance on your project with less need for maintenance.
- Yanmar ViO80: The ViO80 has a robust build and is made to withstand tough conditions. Its maintenance is straightforward, with easy access to key components like the engine and hydraulics. Yanmar machines are also praised for their fuel efficiency, which can help keep operating costs down over time.
A
- Kubota KX080-3S: Kubota’s reputation for reliability is strong, and the KX080-3S is a testament to that. It’s designed to minimize wear and tear, and its maintenance points are easily accessible. Like the Yanmar, fuel efficiency is also a strong point for the Kubota.
A
Verdict: Both machines offer low maintenance and excellent durability making them suitable for those long-term projects. The decision will come down to brand preference and the specific needs of your project.
