Both the Yanmar Vio17 and Kubota KX018-4 belong to the class of sub-2-ton mini excavators. These machines are designed to deliver powerful performance in confined spaces, often replacing the need for larger equipment in light excavation tasks such as trenching, landscaping, and utility installation.
Yanmar Vio17
Yanmar, a leader in compact machinery, designed the Vio17 to offer maximum performance in a compact form. Known for its versatility, this model features the Zero Tail Swing design, which allows it to work in narrow spaces without overhanging the rear of the machine, making it ideal for confined job sites. The Vio17 also boasts a robust hydraulic system and a powerful engine, allowing it to tackle tough jobs despite its small size.
Kubota KX018-4
The Kubota KX018-4 is another solid contender in the sub-2-ton category, known for its durability, ease of use, and advanced features. Like the Yanmar, the Kubota KX018-4 also features a Zero Tail Swing design, allowing for efficient operation in tight spaces. Kubota’s machines are highly praised for their smooth hydraulics and precise controls, offering a great balance of power and maneuverability for various excavation tasks.
Key Specifications Comparison
To understand the differences in performance and capabilities, let's compare the key specifications of both mini excavators.
Engine Power and Performance

• Yanmar Vio17:
  • Engine: Yanmar 3TNV76 diesel engine
    
  • Power: 13.9 horsepower (10.4 kW)
    
  • Operating Weight: 1,720 kg (3,791 lbs)
    
  • Max Digging Depth: 2.38 meters (7.8 feet)
    
  • Max Reach: 3.80 meters (12.5 feet)
    
• Kubota KX018-4:
  • Engine: Kubota D902-E4B diesel engine
    
  • Power: 17.5 horsepower (13.0 kW)
    
  • Operating Weight: 1,840 kg (4,057 lbs)
    
  • Max Digging Depth: 2.29 meters (7.5 feet)
    
  • Max Reach: 3.85 meters (12.6 feet)
    

While the Kubota KX018-4 has a slightly more powerful engine, the Yanmar Vio17 is still capable of handling a wide range of tasks, especially in more restricted work areas due to its lower operating weight. However, the additional weight and power of the KX018-4 can offer better lifting and digging performance, particularly when handling larger materials or more demanding tasks.
Hydraulics and Lift Capacity

• Yanmar Vio17:
  • Hydraulic Flow: 37.3 l/min
    
  • Lift Capacity (at Ground Level): 1,160 kg (2,560 lbs)
    
• Kubota KX018-4:
  • Hydraulic Flow: 40.0 l/min
    
  • Lift Capacity (at Ground Level): 1,300 kg (2,866 lbs)
    

The Kubota KX018-4 outperforms the Yanmar Vio17 in hydraulic flow and lift capacity, making it more suitable for handling heavier loads. The higher hydraulic flow can lead to quicker work cycles, improving efficiency on the job site.
Maneuverability and Design
Both machines offer exceptional maneuverability, but the design features of each play a role in determining how well they perform in confined spaces.
Yanmar Vio17
The Yanmar Vio17's Zero Tail Swing design allows it to rotate without the risk of hitting obstacles behind it, which is especially important when working near walls or other structures. It’s also equipped with a spacious cabin for the operator, allowing for better visibility and comfort during extended use. Additionally, its compact size makes it easier to transport on a trailer without requiring special permits.
Kubota KX018-4
Kubota’s KX018-4 also features Zero Tail Swing, which allows for similar maneuverability. However, the KX018-4’s advanced suspension system offers a smoother ride, which is an important factor when working on uneven terrain. The KX018-4 is known for its precise control, providing operators with excellent control over digging and lifting actions.
Comfort and Operator Experience
Operator comfort is a key factor in determining the overall user experience for mini excavators, particularly for operators who spend long hours in the machine.
Yanmar Vio17
The Yanmar Vio17 offers a well-appointed operator’s station with a spacious, comfortable seat, good visibility, and easy-to-use controls. The design focuses on minimizing operator fatigue, with intuitive joystick controls and well-placed levers for ease of use. The machine’s compact size also helps make it more agile for operators working in confined spaces.
Kubota KX018-4
Kubota is known for designing machines with a focus on operator comfort. The KX018-4 features an ergonomically designed cabin with ample legroom, easy-to-reach controls, and high-quality seats that reduce fatigue during extended operations. The intuitive controls and quiet operation are also beneficial for operators working in urban areas where noise reduction is critical.
Durability and Maintenance
Both the Yanmar Vio17 and Kubota KX018-4 are built to withstand the rigors of daily construction and excavation tasks, but regular maintenance is key to ensuring long-term performance.
