Detailed Specifications

Understanding the specs of the Kubota U35-4 is crucial for determining if it meets your project requirements. Let’s break down the key specifications:

Engine

The heart of the U35-4 is its Kubota D1703-M-DI-E4 diesel engine. This engine is known for its durability and fuel efficiency. It's a liquid-cooled, three-cylinder engine that delivers reliable power in a compact package. The direct injection system enhances fuel combustion, resulting in better fuel economy and reduced emissions. This is a significant advantage, especially when working on projects with strict environmental regulations. The engine is also designed to minimize noise and vibration, contributing to a more comfortable working environment for the operator. Regular maintenance, such as oil changes and filter replacements, is essential to keep the engine running smoothly and extend its lifespan. Kubota's reputation for producing high-quality engines ensures that the U35-4 can handle demanding tasks with ease.

Operating Weight

The operating weight of the Kubota U35-4 is approximately 8,378 pounds (3,800 kg). This weight includes the machine itself, the operator, and a full tank of fuel. The operating weight is an important factor to consider, as it affects the machine's stability and transportability. A heavier machine generally provides better stability, allowing it to handle larger loads and work on uneven terrain with greater confidence. However, a heavier machine may also be more difficult and costly to transport between job sites. The U35-4 strikes a good balance between weight and maneuverability, making it suitable for a wide range of applications. Its weight distribution is carefully engineered to optimize stability without sacrificing agility. When transporting the U35-4, it's essential to use a trailer that is rated to handle its operating weight safely. Always consult the manufacturer's guidelines for proper transportation procedures.

Digging Depth and Reach

The Kubota U35-4 offers a maximum digging depth of 11 feet 1 inch (3.38 meters) and a maximum reach of 17 feet 9 inches (5.41 meters). These figures are critical for understanding the machine's capabilities in excavation and trenching tasks. The digging depth determines how deep the excavator can dig below the surface, while the reach indicates how far it can extend its arm to perform tasks. The U35-4's digging depth is sufficient for most common excavation projects, such as digging foundations, utility trenches, and drainage systems. Its reach allows it to work efficiently over obstacles and in confined spaces. The boom and arm geometry are designed to provide optimal digging force and control, allowing the operator to perform precise movements with ease. When operating the U35-4, it's important to be aware of underground utilities and other potential hazards. Always check the digging area for buried cables and pipes before starting any excavation work. Using the appropriate digging techniques and attachments can also improve the machine's performance and safety.

Hydraulic System

The hydraulic system of the Kubota U35-4 is a key component that powers its various functions, including digging, lifting, and maneuvering. The system operates at a pressure of 2,987 psi (206 bar), providing ample hydraulic power for demanding tasks. The hydraulic flow rate is 16.9 gallons per minute (64 liters per minute), ensuring quick and responsive operation. The hydraulic system is designed with advanced features, such as load-sensing hydraulics, which optimize performance and efficiency. Load-sensing hydraulics adjust the hydraulic flow and pressure according to the load on the machine, reducing energy waste and improving fuel economy. The system also includes hydraulic pilot controls, which provide smooth and precise control over the machine's movements. This allows the operator to perform intricate tasks with greater accuracy and confidence. Regular maintenance of the hydraulic system, such as checking fluid levels and inspecting hoses for leaks, is essential to ensure its reliable operation. Using high-quality hydraulic fluid and filters can also extend the lifespan of the system and prevent costly repairs.

Dimensions

The compact dimensions of the Kubota U35-4 are one of its key advantages, allowing it to work in confined spaces where larger excavators cannot. The overall width of the machine is 5 feet 7 inches (1.7 meters), making it easy to maneuver through narrow passages and doorways. The overall height is 8 feet 1 inch (2.46 meters), allowing it to work under low overhangs and inside buildings with limited headroom. The tail swing radius is zero, meaning that the rear of the machine does not extend beyond the width of the tracks when it rotates. This is a crucial feature for working in tight spaces, as it eliminates the risk of hitting obstacles or damaging property. The compact dimensions of the U35-4 also make it easier to transport between job sites, as it can be loaded onto a smaller trailer. When operating the machine in confined spaces, it's important to be aware of your surroundings and to take extra precautions to avoid collisions. Using spotters and safety cones can help to ensure a safe working environment.
