Kubota U25 |
| |
| Features |
AUXILIARY HYDRAULICS
Designed to accommodate a variety of attachments, such as breakers and augers,
the U25’s auxiliary hydraulic system consists of port pipes on the arm, bidirectional
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. |
 |
| |
DIGITAL PANEL
Kubota’s Intelligent Control System can help reduce downtime and repair fees by
providing timely diagnostic readings and routine maintenance alerts. The large
digital panel displays current working conditions, warning indicators, engine rpm and
hour meter, fuel, temperature and oil levels. The panel not only lets you know when
fuel is running low, but alerts you during refueling when the tank is nearly full. |
 |
| |
PROTECTED HOSES
For greater protection, the U25’s front hoses are routed within the arm. This design
also improves operator visibility, increases hose service life, and lowers repair costs. |
 |
| |
STRONG BUCKET FORCE
The U25 offers a powerful breakout force: 5,765 lbs with the dedicated bucket and
quick coupler. That’s more than enough to keep the U25 working efficiently even
under the heaviest loads on the toughest excavating jobs. |
 |
| |
TRAVEL SPEED SELECTOR
By placing the 2 speed
travel switch on the dozer lever, dozing operations have
become faster and easier. The new location also frees up space on the floor for
improved operator comfort. |  |
| |
WIDE FOOT SPACE
More spacious than many conventional tail swing excavators, the U25's wider foot
space enhances operator comfort.
|
 |
| |
WRIST REST
Adjustable wrist rests help reduce arm movement and increase operator comfort for
greater work efficiency.
|
 |
| |
EASY MAINTENANCE
Daily maintenance is easy, thanks to side opening
covers that provide fast access to
all critical components. The reserve tank, air filter, fuel filter, water separator, and
engine oil gauge are all easily accessible behind the rear engine cover. An engine
inspection window behind the seat provides fast access to the engine filling port. The
side cover provides access to the battery and radiator. |
| |
EXCEPTIONAL BALANCE
Powerful and responsive, the U25’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 remains supremely stable,
thanks to its innovative counter balancing technology, long tumbler distance, and
Double Outer Flanged Lower Track Rollers. |
 |
| |
|
PIN BUSHINGS
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. |
 |
| |
|
HIGH BACK SUSPENSION SEAT
The U15’s deluxe high back
seat increases productivity by providing optimum
comfort for operators of all sizes. Retractable seat belts increase ease of use. |
 |
| |
|
THUMB BRACKET
The optional hydraulic thumb allows you to handle a variety of loading and digging
jobs without stopping to change implements. It works with the bucket to pinch
materials for loading and carrying. When no longer needed, it retracts to permit
normal excavation. The U25’s factory installed
thumb bracket and auxiliary
hydraulics significantly reduce the time needed to mount the hydraulic thumb. |
 |
| |
|
TRACK ROLLERS
The permanently lubricated upper track rollers prevent the tracks from
hitting the frame while the machine is moving, reducing both noise and
wear. Dual flange lower track smooth travel vibrations and improve
stability over the side. |
 |
| |
|
TWO-PATTERN SELECTION
With a quick flip of a lever, it's easy to change the operating pattern. That's great for
improved productivity and safety. |
 |
| |
|
ROPS / FOPS CANOPY
The OSHA certified ROPS/FOPS canopy provides complete protection from
accidental rollovers and falling objects, ensuring an extra level of safety and security
on the job. |
 |
| |
|
SAFE, CONTROLLED STARTS
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. |
 |
| |
|
SMOOTH OPERATION
Smooth operation across a wide range of jobs is assured, thanks to the U25’s
advanced variable displacement pumps and Hydraulic Matching System. |
 |
| |
|
STRAIGHT TRAVEL
Kubota’s Hydraulic Matching System keeps the U25 traveling in a straight line while
operating the boom, ensuring safer loading and offloading. |
 |
| |
|
SWIVEL NEGATIVE BRAKE
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. |
 |
| |
|
| ZERO TAIL SWING
Tough job got you in a corner? Put a U25 to work on it. Zerotail
swing keeps the tail
within the width of the tracks, so you can turn the house throughout its 360degree
turning radius without worrying about what is to the side or behind you. Zerotail
swing also ensures excellent balance, stability and fast operation, making the U25
ideal for jobs in congested urban areas. |
