5.5T Kubota Excavator – U55-4
Maximum Power. Zero Tail Swing. Built for Heavy-Duty Performance.
The 5.5T Kubota U55-4 Excavator is a powerful, compact, and highly capable machine designed for demanding construction, civil, landscaping, and earthmoving applications. Combining impressive digging performance with Kubota’s zero-tail swing design, the U55-4 delivers exceptional productivity while maintaining maneuverability in tight-access worksites. Built with durability, operator comfort, and versatility in mind, this mid-size excavator is ideal for contractors who need serious power without moving into a full-size machine.
Powered by a reliable 47.6HP Kubota V2607 direct injection diesel engine, the U55-4 provides outstanding digging and lifting capability with smooth hydraulic response and reduced noise and vibration. The high-performance engine is engineered to maximise productivity while maintaining fuel efficiency, making it suitable for long operating hours across demanding job sites. This combination of power and efficiency allows the U55-4 to handle trenching, bulk excavation, footings, site preparation, and heavy material handling with ease.
Despite its strong performance, the Kubota U55-4 maintains a compact, well-balanced design with true zero-tail swing. This allows the machine to rotate 360 degrees while keeping the rear within the track width, making it ideal for working near buildings, fences, and confined spaces. The compact footprint improves maneuverability while still providing excellent stability for digging and lifting operations, making it perfect for urban construction, road works, and residential developments.
The U55-4 is also available with an optional angle blade, providing additional versatility on site. The blade can be angled left or right to push soil to the side while moving forward, improving efficiency during backfilling and grading. This reduces the need for repositioning the machine and helps operators complete jobs faster, especially during trenching and finishing tasks.
Operator comfort is a key feature of the Kubota U55-4. The spacious operator station provides excellent visibility and ergonomic controls for precise handling. Smooth pilot controls allow accurate operation, while the balanced design reduces vibration and fatigue during long working hours. Optional cab configurations further enhance comfort by providing protection from weather and site conditions, improving productivity throughout the day.
Built for durability, the U55-4 features heavy-duty components, reinforced construction, and protected hydraulic systems designed to handle tough Australian job sites. Wide-opening side panels provide easy access for servicing, while simplified maintenance points reduce downtime and keep the machine working longer. Kubota’s engineering ensures long-term reliability and lower operating costs across the life of the machine.
The Kubota U55-4 is highly versatile and compatible with a wide range of attachments including buckets, augers, hydraulic hammers, grabs, and rippers. With strong auxiliary hydraulic flow and excellent breakout force, the machine can easily switch between tasks such as trenching, post hole boring, landscaping, light demolition, and site clean-up. This flexibility makes it an ideal all-rounder for contractors needing one machine for multiple applications.
With an operating weight of approximately 5.3–5.6 tonnes and a compact transport width of around 1,960mm, the U55-4 offers an excellent balance between mobility and performance. It delivers the power of a larger excavator while still being easy to transport between job sites.
If you’re looking for a powerful mid-size excavator that combines compact dimensions, zero-tail swing maneuverability, and outstanding digging performance, the 5.5T Kubota U55-4 is the ideal solution. Built for heavy-duty applications yet versatile enough for tight-access work, the U55-4 is designed to maximise productivity across every job.
