Excavator U55-4

Industrial Equipment

Now available with optional angle blade, the Kubota U55-4 offers customers versatility never seen before in the mid size 5 tonne excavator market. Powered by a reliable Kubota 47.6HP engine, the Kubota U55-4 features a compact and well balanced design, combining exceptional power and the versatility to tackle any job and working condition with ease.

Engine & Service

Powered by Kubota’s impressive 47.6 HP direct injection V2607-DI engine (Tier IV compliant). Engineered with the power to maximise digging and lifting performance, it also delivers minimised noise, vibration and fuel consumption.

Two-piece hose design for the dozer simplifies hose replacement and reduces downtime. Single sided maintenance for operator convenience and easy access to daily maintenance components. Front pin bushes maximise durability and longevity to cut downtime. The U55-4 features long-lasting side panels that open easily for quick inspection and routine maintenance. The panels are located inside the counterweight edge for protection and durability.


Deluxe interior features suspension seat and ergonomically designed controls provides superior comfort during those long hours in the cab. Wider entrance for easy entry and exit from the cab along with spacious operating area. New digital panel puts all functions at your fingertips for operator convenience and records up to 90 days of operation history.


Kubota’s 3-pump load sensing hydraulic system ensures smoother operation, regardless of load size. It allows hydraulic oil to flow according to the specific range of the operator’s lever motion. The result is greater fuel economy and smoother travelling. The maximum oil flow settings of auxiliary circuits 1 and 2 are conveniently adjustable from the digital panel – no additional tools or complex manual adjusting procedures are necessary. You can even program up to five oil flow rates corresponding to specific attachments into memory on the digital panel.


Auto travel shift system automatically shifts from high to low range travel speeds giving operators smoother operation when dozing or turning. Two Pattern Selection System provides the operator the versatility to switch between ISO and SAE pattern. Great if you have more than one person operating the machine. Float position adjusts the dozer height to make a clean level when backfilling, simply travel backwards with the dozer in the float position.

Angle Blade

Save time and work more efficiently. With a simple movement of the dozer lever, the hydraulic angle blade can be angled to the right or left to push soil to the side as the machine moves forward, eliminating the need for repetitive repositioning at right angles when backfilling trenches. The float function is a standard feature on the U55-4*. Ground finishing work can be completed quickly and simply without the need to adjust the dozer height. After backfilling, simply travel backwards along the covered ditch with the dozer in the float position. *Standard on both angle blade & standard blade models. Angle blade operation is designed for easy control. Up, down and float movements are made with a single lever, while left and right angle positioning is made by the rocker switch on top of the lever.The angle blade lets you work efficiently in confined spaces, alongside walls, and near busy roads – no wider than the tracks, it’s also easy to transport between jobs.


ROPS and FOPS certified for ease of mind when entering any job site. Auto idle system automatically reduces RPM’s when control levers are left stationary, reducing noise and increasing cost savings. Fuel overflow prevention system beeps in intervals to indicate when full, avoiding spillage. Pre-cleaner system fitted to protect the engine in extreme dusty Australian conditions.
