Small but perfectly formed

Kubota NZ has added another machine to its KX series of excavators.

The KX033-4 compact excavator is said to offer efficiency, stability and comfort alongside power and style in the competitive 3-tonne class. 

The new unit shares many of the standard features of Kubota’s larger machines, e.g. a larger cab, dash-controlled pre-sets for auxiliary circuits and a standard hydraulic diverter valve. 

But the company claims the KX033-4 delivers best-in-class hydraulic breakout power of 3690kg, a digging depth of 3m and fast cycle times. This all helps to move more material per hour when tested head-to-head against other 3t excavators. 

Power comes from a 24.8hp Kubota direct injection Tier 4 Final certified engine. The engine RPM may be set to automatically idle when control levers are in neutral for more than four seconds, saving fuel and cutting noise and emissions. 

Adjustable auxiliary hydraulics allow the operator to program up to five different oil flow rates, controlled from a new digital control panel.

Replacing the popular KX91-3 in the Kubota KX series, the auxiliary hydraulic circuit can deliver a maximum oil flow of 60L to power a wide variety of auxiliary attachments, while the standard third-line hydraulic return system allows oil to return directly back to the tank without flowing through control valves, resulting in less back-pressure, less heat and greater efficiency. 

Thoughtful design and engineering include an innovative counterbalance resulting in stable operation, and a low centre of gravity and double-flanged track rollers that also contribute to safety, whether working to the side with hydraulic attachments or in challenging lifting conditions. 

A swivel negative brake and travel negative brake automatically lock the swivel function and tracks, respectively, to prevent unexpected machine movement and keep the excavator secure.

The KX033-4 operator station has a reclining high-back suspension seat for operator comfort, including weight compensation and firm, adjustable wrist supports. A wider, updated digital display panel with push button operation allows for easy monitoring of critical controls, including changing hydraulic oil flows. 

A ROPS canopy is standard, and the optional cab includes air conditioning, more foot space with a wider door, a gas-assisted front window mechanism, a large cup holder and, of course, a charging point for a mobile phone.
