Hey guys! Ever wondered about the Kubota U55-4 mini excavator specs? This compact powerhouse is a popular choice for construction pros and DIY enthusiasts alike. Let's dive deep into what makes this machine tick, from its engine and digging capabilities to its dimensions and overall performance. We'll break down all the nitty-gritty details, so you can make an informed decision if you're considering adding one to your fleet or renting it for a project.

Engine and Performance

When it comes to the heart of any excavator, the engine is where it all begins. The Kubota U55-4 boasts a robust Kubota V2607-DI-E4 diesel engine. This engine is a 4-cylinder workhorse that delivers a powerful 47.6 horsepower. That's plenty of muscle for a mini excavator, allowing it to tackle a variety of tasks with ease. Whether you're digging trenches, moving materials, or demolishing small structures, this engine provides the necessary grunt.

This engine isn't just about power, though. It's also designed for efficiency and reliability. Kubota is known for its durable and long-lasting engines, and the V2607-DI-E4 is no exception. It's built to withstand the rigors of daily use on the job site, ensuring minimal downtime and maximum productivity. Plus, it meets the latest emission standards, so you can feel good about its environmental impact.

The U55-4's hydraulic system is another key component of its performance. It utilizes a sophisticated system that provides smooth and precise control of the excavator's movements. This is crucial for tasks that require finesse, such as digging around underground utilities or working in tight spaces. The hydraulic system also contributes to the excavator's digging force, allowing it to break through tough soil and materials.

Fuel efficiency is always a concern, and the U55-4 doesn't disappoint. Its engine and hydraulic system are optimized to minimize fuel consumption, saving you money and reducing your environmental footprint. This is a significant advantage, especially for projects that require extended operating hours. With its blend of power, efficiency, and reliability, the Kubota U55-4's engine is a standout feature.

Digging Capabilities

Okay, so we've talked about the engine, but what can this thing actually do? The digging capabilities of the Kubota U55-4 are impressive for its size. It has a maximum digging depth of 11 feet 11 inches, allowing you to tackle a wide range of excavation tasks. Whether you're digging foundations, installing drainage systems, or creating landscaping features, this excavator has the reach you need.

The U55-4's digging force is also worth noting. With a bucket digging force of 9,869 pounds, it can break through tough soil, clay, and even some rocky materials. This is essential for projects that involve challenging ground conditions. The arm digging force, which measures the force exerted by the excavator's arm, is also substantial, contributing to its overall digging power.

The excavator's swing speed is another factor that affects its productivity. The U55-4 has a quick and responsive swing speed, allowing you to move materials efficiently around the job site. This is particularly important when you're working in confined spaces, where maneuverability is key. A faster swing speed translates to more cycles per hour, which means you can get more done in less time.

The U55-4 also features a two-speed travel system, allowing you to adjust the excavator's speed to the terrain and task at hand. The high-speed mode is ideal for moving quickly across the job site, while the low-speed mode provides more precise control for digging and maneuvering in tight spaces. This versatility makes the U55-4 a valuable asset for a variety of applications. Its digging depth, digging force, swing speed, and travel system all contribute to its exceptional digging capabilities.

Dimensions and Size

Now, let's talk about the physical size of this machine. One of the biggest advantages of the Kubota U55-4 is its compact dimensions. It's designed to be easily transported and maneuvered in tight spaces, making it ideal for urban construction sites and residential projects. The overall width of the U55-4 is just 6 feet 5 inches, allowing it to fit through narrow gates and work in confined areas.

The excavator's height is also relatively low, which is beneficial when working under trees or other overhead obstructions. The operating weight of the U55-4 is around 12,682 pounds, which is light enough to be transported on a standard trailer. This makes it easy to move the excavator from one job site to another, saving you time and money.

The U55-4's compact size doesn't mean it sacrifices stability. It has a wide track width and a low center of gravity, which provide excellent stability on uneven terrain. This is crucial for safety and productivity, as it allows you to work confidently even on slopes or rough ground. The U55-4's dimensions are a perfect balance of compactness and stability, making it a versatile machine for a wide range of applications.

The minimal tail swing design is another key feature that contributes to the U55-4's maneuverability. This means that the rear of the excavator doesn't extend much beyond the width of the tracks when it swings, allowing you to work close to walls and other obstacles. This is a huge advantage in tight spaces, where a conventional excavator might not be able to operate.

Features and Technology

Beyond the basic specs, the Kubota U55-4 is packed with features and technology that enhance its performance and operator comfort. The cab is designed to be spacious and comfortable, with excellent visibility and ergonomic controls. This is important for reducing operator fatigue and maximizing productivity. The U55-4 also features a digital display that provides real-time information about the excavator's performance, such as fuel consumption, engine temperature, and hydraulic pressure.

The U55-4's hydraulic system includes features like load-sensing hydraulics and proportional flow control, which provide smooth and precise control of the excavator's movements. These features make it easier to dig accurately and efficiently, even in challenging conditions. The excavator also has auxiliary hydraulic circuits, which allow you to connect a variety of attachments, such as hydraulic breakers, augers, and grapples.

Safety is always a top priority, and the U55-4 includes several features to protect the operator and those around the job site. These include a rollover protective structure (ROPS) and a falling object protective structure (FOPS), which are designed to protect the operator in the event of an accident. The excavator also has a travel alarm, which alerts others when the machine is moving.

The U55-4's technology extends to its maintenance features as well. It has easy-to-access service points, which make routine maintenance tasks like changing fluids and filters quick and simple. This helps to minimize downtime and keep the excavator running smoothly. With its combination of advanced features, comfortable cab, and safety features, the Kubota U55-4 is a technologically advanced mini excavator.
