Around the world, producers and operators rely on Kubota diesel engines to power their small excavators. Kubota engines, such as the D902, D722, and Z482, are well-known for their dependability, fuel efficiency, and small size. They power a variety of small construction tools, particularly mini excavators.
However, you may be wondering whether the Kubota engine is appropriate for your particular excavator demands if you're looking to update or buy a new machine. To assist you in making a decision, let's examine these three well-known engine models in more detail.
The Kubota Z482 is lightweight and compact
In this series, Kubota's smallest diesel engine is the Z482. This engine's two cylinders and modest size make it perfect for extremely small excavators and confined work areas.
Overview of the Engines
Here’s a quick breakdown of the three Kubota engines commonly found in mini excavators:
Engine Model Cylinders Displacement Horsepower (approx.) Cooling
Z482 2-cylinder 479cc ~13 HP Liquid-cooled
D722 3-cylinder 719cc ~17 HP Liquid-cooled
D902 3-cylinder 898cc ~25 HP Liquid-cooled
Kubota Z482 – Compact and Lightweight
The Z482 is surprisingly powerful for light-duty tasks like trenching, landscaping, and utility work in residential areas, considering its compact size. It is frequently found in low-priced excavators and other devices where cost, weight, and space are important factors.
Ideal For:
Small-scale housing developments
DIYers and homeowners
Operators at the entry level
Inconsistent use or constrained urban areas
Kubota D722: Reliable and Balanced
The D722 is an upgraded version of the Z482 with three cylinders and a larger displacement. This makes it a good middle-ground option because it produces more constant output, better torque, and smoother operation.
Compact excavators that must regularly manage moderate workloads frequently use this engine. The D722 is an excellent choice if you're a small business owner, contractor, or landscaper searching for a dependable workhorse without using excessive amounts of power.
Ideal For:
- Commercial use on a daily basis
- Small contractors and landscapers
- General construction
- Users seeking a mix between fuel efficiency and power
Performance and Power of the Kubota D902
The Kubota D902, a three-cylinder diesel engine with a displacement of around 900cc and a maximum horsepower of 25, is at the top of the list. This engine is powerful despite its small size, which makes it perfect for heavy-duty tasks in small machines.
High-performance mini excavators that require greater torque and greater lifting capacities, such as the TYPHON TERROR XVIII, frequently have it. To further operator adaptability, the D902 also accepts hydraulic accessories such as thumbs, breakers, and augers.
Ideal For:
- Expert contractors
- Demanding work environments
- Utilize hydraulic tools.
- Commercial construction and excavation
