U45

Clean-running Kubota Engine (Interim Tier IV)
Clean-running Kubota Engine Powerful and dependable, the U45S's diesel engine delivers superior horsepower and performance. It offers low noise and vibration levels, exceptional fuel efficiency, and complies with the EPA's 2008 interim Tier IV emissions regulations.

Zero tail swing
With zero-tail swing, even the tightest spaces become efficient work places. Because the tail always stays within the width of the tracks, you can turn the house throughout its 360-degree turning radius without damage to the machine or surroundings. Zero-tail swing also ensures excellent balance and stability and faster operation, making the U45S ideal for work in congested urban areas.

Adjustable max. oil flow on auxiliary circuit
Adjustable max. oil flow on auxiliary circuit This unique function lets you control the oil flow according to your needs or the attachment in use. It eliminates the hassle of using tools to change settings manually, so you don't have to leave the cabin. When using a tilt bucket, you can slow the flow to get just the right control to gently shape a swale. Alternatively, for a brush cutter, direct the oil flow to one side of the excavator arm. The system will even store your settings for the next time you need it, saving time and quickly regulating the flow requirements. Adjustable oil flow enhances performance and saves fuel.

Angle blade with floating position as standard
Angle blade with floating position as standard Save time and work more efficiently. With a simple movement of the dozer lever, the hydraulic angle blade can be angled to the right or left to push soil to the side as the machine moves forward, eliminating the need for repetitive repositioning at right angles when backfilling trenches.

Load-sensing hydraulic system
With Kubota's advanced Load Sensing Hydraulic System, even the slightest lever movements produce smooth and simultaneous operation of the boom, arm, bucket, and house. Control valves automatically regulate and distribute the optimum amount of oil to each cylinder based on the weight of the load, resulting in perfectly matched speed, power, and cylinder timing.

Thumb bracket and relief valve as standard
Thumb bracket and relief valve as standard The factory-installed thumb bracket and relief valve significantly reduce the time needed to mount the optional hydraulic thumb, which makes short work of a variety of loading and material handling jobs.

Standard third line hydraulic return to tank
Standard third line hydraulic return to tank When working with one-way hydraulic attachments, such as a breaker or brush cutter, the standard third-line hydraulic return system allows oil to flow directly back to the tank without running through the control valves. This contributes to less oil contamination, reduced back pressure, and greater oil flow efficiency.
