Engine
Powered by a Kubota 20.9HP engine, for powerful performance and agility to get in and out of the tightest spaces with ease. The U25-3S diesel engine delivers superior horsepower and performance. It offers low noise and vibration levels, exceptional fuel efficiency, and complies with the EPA’s 2013 Tier IV emissions regulations.
Comfort
Deluxe interior with spacious flat foot space to enhance comfort with more leg room for the operator. New user friendly digital panel positioned for better visibility and convenience at your fingertips featuring an easy one touch button operation. Suspension seat designed for better fit and operator comfort to minimise fatigue for long hours of work.
Hydraulics
A quick flip of a lever lets you switch operating patterns from ISO to SAE or vice versa. Located above the boom, the boom cylinder remains safe from damage during breaker or dumping operations. The cylinder design features a larger diameter rod and increased hydraulic pressure for greater lifting power and optimum front attachment speeds. Designed to accommodate a variety of attachments, such as breakers and augers, the U25-3S’s auxiliary hydraulic system consists of port pipes on the arm, bi-directional auxiliary hydraulic controls, and a control value. The auxiliary hydraulic connections are located within easy reach and incorporate short hoses that are less likely to become tangled or damaged.
Front Bush Pins
Pin bushings are installed at all of the pivot points along the swing bracket, boom, arm, and bucket. Pin type bushings not only last longer, they are easier to replace when necessary.
Stability
When the safety control lever is moved upward, the console moves with it, providing more room for entry and exit. To prevent unexpected machine movement during entry or exit, the pilot and travel controls are then disabled. This is the only time that the engine will crank over. The U25-3’s Hydraulic Matching System ensures safer loading and off-loading by keeping the U25-3 traveling in a straight line while operating the boom. Whenever the engine is stopped or the safety control lever is raised, the swivel negative brake automatically locks the house in its current position, thus eliminating the need for a swivel transport lock pin.
Breakout Force
The U25-3S offers a powerful breakout force: 2,320 kg with the dedicated bucket and quick coupler. That’s more than enough to keep the U25-3S working efficiently even under the heaviest loads on the toughest excavating jobs.
Versatility
Powerful and responsive, the U25-3S’s front working group provides superior lifting capacity for digging, lifting, and loading. Even when working to the side, using hydraulic attachments, or lifting heavy objects, the U25-3S remains supremely stable, thanks to its innovative counter balancing technology, long tumbler distance, and Double Outer Flanged Lower Track Rollers.
