A comfortable operator is a productive operator. That’s why the U18-5 operators’ space has been enhanced to ensure optimum comfort and efficiency throughout the working day. All controls are ergonomically placed for faster and easier operation. The front meter panel can be checked without shifting your eyes from the task in hand. The mobile phone holder is within easy reach from the operator’s seat and charges your phone as you work.
Mini-Excavators
U18-5
ALL-NEW LEVELS OF COMFORT AND PERFORMANCE
Already acclaimed for its outstanding productivity, Kubota’s U17 mini-excavator has been redesigned to offer even better performance and efficiency. With improved operability and stability, the all-new U18-5 improves your efficiency. The productivity is further enhanced by a redesigned operator space that maximises operator comfort and efficiency.
COMFORTABLE OPERATOR SPACE
ENHANCED TRAVELLING PERFORMANCE
The arm, bucket, boom and AUX can be operated without affecting traveling performance, thanks to the travel-independent hydraulic circuit.
VARIABLE TRACK GAUGE
The U18-5’s track gauge can be expanded to a maximum of 1,300 mm to optimize stability when using heavy attachments. For better side stability, the maximum track expansion has been increased by 60mm. The track gauge can also be retracted to 990 mm for easier movement through narrow passageways and to allow work in tight spaces.
EASY MAINTENANCE
When maintenance is simple, downtime is greatly reduced and you're more productive. With the U18-5, routine maintenance is easy-the rear bonnet and the left side cover opens up without the need for tools. This allows for quick access to the engine oil dipstick, water separator, radiator, battery and much more. Plus, for extra strength and easier repairs, the U18-5’s bonnet and side covers are made of steel.
AUTO IDLING SYSTEM
Save fuel, lower noise and exhaust emissions, and reduce operating costs with Kubota’s Auto Idling system. When the control levers are in neutral for more than 4 seconds, the engine RPM automatically idles. Move any control lever and the engine RPM immediately returns.
AUTO-SHIFT
The auto-shift system enables automatic travel shift from high to low depending on traction effort and terrain. This gives smoother operations when dozing and turning.

ENGINE
- Kubota’s Stage V compliant original engine is at the heart of the U18-5, meeting all current engine emission regulations.
- The rear bonnet, side covers, and the under-seat cover open up without the need for tools for easy maintenance.
- Rapid access to the engine oil gauge, radiator, battery, air and fuel filters, and much more.
- Life the rubber mat and open the floor plate for easy access to under-deck hydraulics.
- The U18-5’s bonnet and side covers are made of steel.
HYDRAULICS
- The boom cylinder is situated above the boom for protection when breaking or dumping.
- Movement speeds of front attachments and lifting power are well adjusted, thanks to the boom cylinder’s large-diameter rod and optimal hydraulic pressure.
- Standard features include a pressure accumulator, hydraulic pressure checking ports, a third line hydraulic direct return for the AUX feature, a variable displacement pump, and a straight travel circuit.
- Travel motor hoses are sited within the track frame for added protection – a unique feature for mini-excavators of this class.
- Front cylinder hoses are routed through the boom for increased protection, extended service life and greater operator visibility.
- Auxiliary hoses extend only to the top of the arm to protect them from potential damage during narrow-width bucket use.
- The two-piece hose configuration on both dozer and boom cylinders reduces the amount of time needed for hose replacement.
VERSATILITY
- Kubota’s zero-tail swing makes the U18-5 ensures a 360˚ swivel, excellent stability and smooth control, combined with superb power and efficiency, enabling superior performance even in heavy traffic areas and inside buildings.
- The adjustable track easily switches from 990m to 1300mm width for even greater stability and manoeuvrability.
PERFORMANCE
- The dozer lever features a 2-speed travel switch, which enables the operator to easily select between power or travel speed during levelling work, depending on the load.
- Informative, interactive and functional. Kubota’s Intelligent Control System keeps you in tune of the U18-5’s vital signs. It accurately displays easy-to-understand diagnostics of current working conditions and warning indicators for engine rpm and hour meter, as well as for fuel, temperature and oil levels. When filling up with fuel, the panel also informs the operator that the tank is nearly full and alerts the operator when routine maintenance is due. Overall, the panel reduces excavator repair time for lower total operating costs.
- For increased durability, bushings are included for all of the U18-5’s pivot points on the swing bracket, as well as critical jointed points. If necessary, the bushings can be easily replaced.
COMFORT
- Weight-adjustable semi suspension seat and retractable orange seatbelt with alert function.
- Hydraulic pilot control levers with wrist rests.
SAFETY
- ROPS (Roll-Over Protective Structure, ISO3471)
- TOPS (Tip-Over Protective Structure)
- Green rotating beacon predisposition
- Kubota’s industry-leading, Thatcham-approved antitheft system is standard. Only programmed keys will enable the engine to start up. Attempting to start with an un-programmed key will activate the alarm.
