The Kubota U145 midi excavator has an operating weight ranging from approximately 14,640 kg to 15,696 kg, depending on whether it is configured with a mono boom or 2-piece boom.

This places the U145 at the upper end of the midi excavator class, offering strong lifting stability and digging performance without moving into the full-size excavator category. For contractors upgrading from a 8–10 tonne machine, the U145 provides a clear step up in reach, breakout force, and site capability while still maintaining short tail swing practicality.

The Kubota U145 midi excavator is powered by an Isuzu VD-4JJ1X 4-cylinder diesel engine producing 106.7 PS (78.5 kW) at 2000 rpm. This high-output engine uses a common rail fuel injection system, turbocharger, and air-cooled intercooler for efficient combustion and consistent torque.

The engine is fully EU Stage V compliant, making the U145 suitable for regulated construction sites across the UK. For contractors working in low-emission zones or public sector projects, this means strong performance with reduced exhaust output and improved fuel control.

The Kubota U145 midi excavator features three selectable working modes: SP (Super Power), H (Heavy), and A (Auto).

SP mode increases hydraulic output for faster cycle times.

H mode supports demanding digging and lifting tasks.

A mode provides fuel-efficient operation and includes six selectable levels to match site conditions.

Combined with Auto Idle, Idle Shut Down, Spool Stroke Control (SSC), and Boom-down Energy Save (BES), the U145 balances performance and fuel economy across different applications, from trenching to heavy excavation.

Yes, the Kubota U145 midi excavator comes with AUX1 and AUX2 auxiliary hydraulic circuits as standard.

Oil flow is adjustable, allowing the operator to match hydraulic output to attachments such as breakers, grabs, tilt buckets, compactors, and augers.

The U145 also features automatic power boost and smooth simultaneous operation of boom, arm, bucket, and swing. For plant hire companies and groundworks contractors, this means flexibility across multiple tasks without changing machines.

Yes, the Kubota U145 is designed as a zero-tail swing midi excavator.

Its compact rear profile allows it to operate safely in restricted areas such as roadside projects, housing developments, and tight commercial sites. Zero-tail swing reduces the risk of rear-end contact with barriers or passing traffic. For contractors working in urban environments, the U145 offers the digging strength of a 14–15 tonne machine with the manoeuvrability required for confined working conditions.

That depends on your work. The standard mono boom is strong, straightforward, and ideal for general excavation. The 2-piece boom offers added flexibility—great for reaching further, digging closer to the machine, or working in tight or awkward spaces. If you're often on confined sites or doing precision digging, the 2-piece boom is worth it.

The Kubota U145 midi excavator includes a ROPS-certified cab and OPG Level 2 (FOPS Level 2 top guard) as standard.

A 230-degree surround view camera system with rear, right, and left cameras is fitted as standard to improve visibility.

The machine also includes a travel alarm, anti-theft system, emergency exit hammer, and engine auto stop.

These features support safe operation on busy construction sites and help contractors meet health and safety compliance standards.

The Kubota U145 midi excavator has a 200-litre fuel tank capacity. This larger tank size allows for extended working hours between refuelling, which is valuable on remote sites or long shifts.

The machine also includes a standard 100 l/min refuelling pump with automatic cut-off to reduce downtime during filling. Combined with Auto Idle and fuel-saving control systems, the U145 is built to balance power output with practical fuel management.

YES! The Kubota U145 midi excavator is well suited to plant hire fleets. It combines brand reputation, operator-friendly controls, Stage V compliance, and strong lifting stability. Features such as the surround camera system, heated air suspension seat, and 178 mm colour LCD monitor make it attractive to operators. For hire firms, durability, resale value, and attachment compatibility are key advantages of the U145 in the competitive 14-tonne midi excavator sector.
