IHI Mini Excavator: NX-2 series mini excavators from 9NX-2 to 35NX-2 with Yanmar TNV diesel engines, 7.5 to 19.8 kW and 934 to 3,519 kg operating weight
IHI (Ishikawajima-Harima Heavy Industries) is a Japanese shipbuilding and heavy-industry group whose construction equipment arm now trades as Kato-IHI. This page gathers the second-generation NX mini excavators, from the smallest 9NX-2 to the largest 35NX-2. The number in the type designation gives roughly the weight class in kilograms times a hundred – the 9NX-2 sits around 900 kg, the 35NX-2 around 3,500 kg – while NX marks the model generation. The excavators are driven by two- and three-cylinder diesel engines from Yanmar's TNV range (2TNV70, 3TNV70, 3TNV76, 3TNV84), with output varying by machine size.

The register lists here 8 versions with 7.5 to 19.8 kW and operating weights from 934 to 3,519 kg.
Mini excavators of this class are a core segment in Japan, where narrow lanes and small plots demand compact machines; IHI ranks there alongside Kubota, Yanmar and Takeuchi as an established maker, and the NX range is also exported.
For a used purchase, check the condition of the rubber tracks and track guides, the tightness of the bucket and boom hydraulic cylinders, the condition of the Yanmar engine, and wear on the swing bearing and slew gear; parts for the TNV engines are widely available on the open market, IHI-specific attachments less so. It is also worth checking the auxiliary hydraulics for attachments such as a hydraulic breaker or ditching bucket, often fitted retrospectively on machines of this size.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Check the weights in the papers against the figures here — attachments change them.
- Ask about parts availability for this build year — the running costs hang on it.
