U30-6Kubota Mini Excavator

Handle any job with confidence. The Kubota U30-6 combines superior power and outstanding versatility to tackle demanding jobs in a variety of conditions. More powerful bucket breakout force results in the smooth, productive operation Kubota machines are known for.

Kubota's zero-tail swing always keeps the tail of the mini excavator within track-width when swivelling, enabling operation in tight and confined spaces.

Zero-Tail Swing

H·M·S Hydraulic SystemKubota features its “three-pump” system, which uses three independent pumps for boom, arm and swivel for more efficient bucket operation. The system’s high capacity control valve and hydraulic variable pumps enable high digging and lifting performance.

By placing the 2-speed travel switch on the dozer lever, dozing operations can be done faster and easier.

The standard travel pedals facilitates ease of tracking.

When working with one-way hydraulic attachments, such as a breaker, 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.

Carefully designed for safety to protect operator while providing the comfortable and reliable operating space.

Safety & Operator ComfortThe world-class ROPS/FOPS canopy (supplied with seat belts) is used for enhanced operator safety.

The engine can be started up only when the safety lever is set at locking position. If safety lever is set at locking position, the machine will not move preventing accidents caused by mis-operation.

Engine Start Safety System

When the engine shuts off, the swivel will be locked automatically.

Swivel motor with disc brake

The travel negative brake locks the tracks to prevent inadvertent movement of the machine. This keeps the excavator secure during transport or while parked on slopes.

Kubota's unique anti-drop valve will prevent natural lowering of boom.

Prevention of Boom Lowering

The swing pedal and service port pedal are separated for greater ease of use.

Front Digital Panel

Following the excellence of Kubota’s Intelligent Control System, the new digital panel puts convenience at the operator’s fingertips. Featuring easier button operation, the user-friendly digital panel is positioned to the front right corner of the operator. This operator-facing wider display greatly improves visibility. With easier access, simpler settings, easy-to-read indicators and alerts, you’ll always be aware of the excavator’sfunctioning status.

Kubota’s attention to user-friendliness can even be found in U30-6’s engine layout. Primary engine components are consolidated onto one side for easier access so　inspections and repairs can be made quickly and easily.

Save fuel with Kubota's Auto Idle. 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.This innovative feature reduces noise and exhaust emissions while reducing operating costs.

Auto Idling system

Full opening rear and right side hoods gives easier inspection and routine maintenance.Also durable steel side panels and its positioning inside the counterweight's edge gives panels added protection against inadvertent damage.

Thanks to revised component layout, cooling performance inside bonnet has been improved.

Improved Cooling Performance

Kubota's innovative two-piece hose design for the dozer blade drastically reduces hose replacement time. This design virtually eliminates the need to enter the machine for maintenance.
