On a mini excavator, the diesel engine is the heart of the machine: it drives the hydraulic pump and dictates power, fuel use and longevity. Two names come up again and again when comparing mini excavators: Laidong and Kubota. This guide compares both engines objectively, without favouring either. The good news: at CZN Machinery, mini excavators come fitted as standard with a Laidong engine, and Kubota is available to order — so you don't have to pick your supplier based on the engine.
Laidong and Kubota: two benchmarks in compact diesel
The Laidong engine
Laidong is a Chinese engine maker specialising in compact diesel engines (single and twin-cylinder) for agriculture and light construction machinery. On CZN mini excavators from 1.25 to 2 tonnes you'll find the Laidong KM385B twin-cylinder, Euro 5 standard: it delivers more torque and smoothness than a single-cylinder from the class below, for more fluid movements and better performance under load on long days.
The Kubota engine
Kubota is a Japanese manufacturer and a global benchmark for compact diesel engines. It powers a large share of European and Japanese mini excavators. Its reputation rests on decades of reliability, a worldwide parts network and proven longevity. It's the industry's "premium" engine, with a higher cost that carries through to the final price of the machine.
Laidong vs Kubota comparison
| Criterion | Laidong | Kubota |
|---|---|---|
| Origin | China | Japan |
| Engine (1–2.5 t mini excavator) | Single / twin-cylinder diesel | Twin / three-cylinder diesel |
| Emissions standard | Euro 5 / Stage V | Stage V |
| Reputation | Reliable, simple, economical | Reliability & longevity benchmark |
| Spare parts | Available, moderate cost | Global network, higher cost |
| Engine cost | Affordable | Premium |
| Impact on machine price | More competitive | Higher |
Reliability and lifespan
Kubota remains the historical benchmark for reliability and longevity — a strong argument for intensive daily use. For its part, the modern Euro 5 Laidong has improved markedly: simple, robust mechanics that are easy to service, it comfortably handles regular use by a private owner, tradesperson or landscaper. In both cases, lifespan mostly comes down to maintenance: a neglected machine wears out fast whatever the engine brand, while a well-serviced engine lasts several thousand hours.
Maintenance and spare parts
The maintenance tasks are identical for both engines: oil change, oil filter, air filter, fuel filter, cooling check. The difference is in the parts: Kubota benefits from a very dense global network (but higher prices), while Laidong parts are available at a moderate cost — at CZN, the France-based aftersales service supplies consumables and wear parts.

Laidong or Kubota: both at CZN
Our mini excavators ship with a Laidong engine. Kubota is available to order.
Impact on the machine price
The engine choice directly affects the final price. A Kubota makes the machine more expensive: it's a premium component, with the brand value that goes with it. Laidong keeps the price highly competitive at comparable performance for most uses. For a private owner or tradesperson working a few dozen days a year, Laidong offers the best value for money. For a professional in intensive use who prioritises the brand and resale value, Kubota makes sense.
At CZN, you choose
Every mini excavator in our range comes fitted as standard with a Euro 5 Laidong engine, with a 2-year warranty and France-based aftersales. If you prefer a Kubota engine, it's available to order: talk to our team, who will give you the lead time and price for your model. The aim is simple: let you choose the engine that matches your budget and priorities, with no compromise on the rest of the machine.
Our verdict
There's no "bad" engine here. Kubota is the premium benchmark: proven reliability, global network, strong brand value — ideal for intensive use and resale. Laidong offers the best value for money: modern, robust and economical to buy and maintain, it perfectly covers the needs of the vast majority of users. The right choice depends on your use and your budget — and at CZN, you don't have to decide between the two when choosing your supplier.
