Kubota, a world leader in the mini excavator industry, has been at the forefront of small excavator manufacturing for decades. Since 1974, when they began producing mini hydraulic excavators, Kubota has consistently led the global trend in small excavators. In 1999, Kubota launched the KingLev series of zero-tail-swing mini excavators, which marked a new concept in the small excavator field. With a range of models from 0.5 to 6 tons, the series has become highly popular, with over 300,000 units sold and continued dominance in the global market for many years. Today, we will focus on one of Kubota's 6-ton mini excavators: the KX155.
Key Specifications
Arm Side Shift Mechanism
The KX155 is equipped with an arm side shift system, allowing for direct digging along tight areas such as walls without the need for constant repositioning of the machine. This feature, combined with the zero-tail-swing design, ensures the KX155 can work efficiently in confined spaces.
Zero Tail Swing Design
The KX155 features a zero-tail-swing structure, meaning that when the upper structure rotates, the tail of the machine does not extend beyond the width of the tracks. This design allows for greater flexibility in tight working environments, making it ideal for urban construction or narrow job sites.
Advanced Hydraulic System
The hydraulic system in the KX155 is designed to deliver oil flow according to the joystick’s movement, rather than load size. This allows the operator to execute tasks with ease, even under minimal load conditions. The engine load is reduced, preventing unnecessary flow loss and improving operational efficiency. The system is capable of fine and compound movements, essential for delicate operations.
Kubota Original Engine
Kubota is one of the few manufacturers that produces its own engines. The V2403-M engine in the KX155 provides 47 horsepower, delivering the necessary power for tough working conditions. This engine meets stringent environmental standards, including the U.S. EPA emissions standards, ensuring both high performance and low environmental impact. The engine operates effectively even in temperatures as low as -15°C, providing reliable performance in various environments.
Clean Engine Technology
Kubota's engine technology is designed to minimize harmful emissions, making it a low-fuel-consumption, environmentally friendly option for operators. The engine is built to meet the needs of the next generation of construction machinery, with an emphasis on reducing pollution and providing energy-efficient performance.
Low-Noise Design
The KX155's engine incorporates several noise-reducing features, including a semi-floating cylinder head cover, molybdenum-coated pistons, and a low-noise F-type fan. These features significantly reduce operational noise, providing a quieter and more comfortable working environment for operators.
ROPS/FOPS Certified Cabin
The KX155 is equipped with a ROPS (Roll-Over Protective Structure) and FOPS (Falling Object Protective Structure) certified cabin, which enhances operator safety. This design meets international standards and provides superior protection for the operator during operation.
User-Friendly Design and Easy Operation
The Kubota KX155 zero-tail-swing mini excavator is a highly efficient and reliable machine, designed to perform in tight and challenging work environments. Its combination of advanced features such as the arm side shift, zero-tail-swing design, and Kubota's powerful and eco-friendly engine makes it an ideal choice for urban construction and other confined-site tasks. With its focus on fuel efficiency, low noise, and user-friendly features, the KX155 is a standout option in the 6-ton mini excavator market.

User-Friendly Design and Easy Operation
- Automatic Idle for Fuel Saving: When the joystick is not moved for 4 seconds, the engine automatically shifts to idle mode, saving fuel. When the joystick is operated again, the engine quickly returns to its previous speed.
- LCD Display with Self-Diagnostic Function: The LCD display provides clear data on operational status, including engine hours, fuel level, water temperature, and engine speed. In case of any abnormalities, the system immediately alerts the operator. This feature helps the operator monitor equipment performance and prevents potential issues.
- Security and Anti-Theft Features: The KX155 has a unique key registration system. Non-registered keys cannot start the engine, and if an attempt is made with an unregistered key, an alarm will sound, ensuring the security of the machine.
- Key Registration System: In case of key loss, operators can insert the "registration key" (red) and then the "sub-key" (black) to register a new key, while rendering the lost key useless.
- Dual-Side Opening Cover: The KX155 features an easy-to-operate dual-side opening cover, allowing operators to quickly access and inspect the engine and fuel system without requiring any tools.
- Simple Maintenance: Maintenance is designed to be quick and efficient. The side and rear covers can be easily removed in just a few minutes, allowing for fast internal inspections and repairs.
