Product Summary

The Kubota KX085-5 is a high-performance compact excavator engineered for operators who demand power, precision, comfort, and reliability on every jobsite. Designed to excel in construction, civil engineering, landscaping, utility installation, demolition, and plant hire applications, the KX085-5 combines advanced hydraulic technology with Kubota’s proven diesel engine platform to deliver exceptional productivity in a compact and highly manoeuvrable machine.

At the heart of the machine is Kubota’s Stage V-compliant V3307 direct injection diesel engine, delivering 66.6 PS (49.0 kW) of dependable power with reduced emissions and impressive fuel efficiency. The engine incorporates a Common Rail System (CRS) and DPF muffler with automatic regeneration technology, helping minimise downtime while extending service intervals and reducing maintenance requirements. Automatic engine idling and engine stop systems further improve fuel economy by reducing unnecessary engine operation during idle periods.

The KX085-5’s advanced load-sensing hydraulic system provides smooth, responsive operation regardless of load conditions. Kubota’s two-pump hydraulic configuration intelligently adjusts oil flow according to operator input, allowing multiple functions to be operated simultaneously with outstanding precision and control. This results in smoother attachment operation, improved efficiency, and enhanced overall machine performance. Dual proportional auxiliary hydraulic circuits with adjustable oil flow settings make the excavator ideal for running hydraulic breakers, augers, grapples, brush cutters, and other powered attachments directly from the cab controls.

Built for versatility, the KX085-5 is available in both mono boom and optional two-piece boom configurations. The two-piece boom significantly increases the machine’s working range, allowing operators to dig deeper, reach higher, and work closer to the machine without constant repositioning. This design is especially effective in confined or restricted spaces where precision excavation and vertical digging are essential. Smooth simultaneous boom, arm, bucket, and slew movements improve productivity and reduce cycle times on demanding jobsites.

The excavator’s compact 2200 mm width and tight tail swing design provide excellent manoeuvrability while maintaining strong lifting capacity and digging performance. The dozer blade float function simplifies grading and backfilling operations by allowing the blade to follow the ground contour automatically for cleaner, faster finishing work. An advanced two-speed auto-shift travel system automatically adjusts speed and traction force based on terrain and load conditions, ensuring smooth travel and better machine control across varying ground conditions.

Operator comfort has been prioritised throughout the cabin design. A spacious cab with low interior noise levels, generous legroom, and enhanced visibility creates a more comfortable working environment during long shifts. The double-adjustable air suspension seat and independently adjustable joystick consoles allow operators to tailor the controls to their preferred working position. Climate control with improved airflow and demisting functionality ensures year-round comfort in all weather conditions. A high-resolution 7-inch full-colour LCD display provides easy access to machine diagnostics, hydraulic settings, maintenance reminders, and rear-view camera monitoring through an intuitive jog dial interface.

Safety and serviceability are also central to the KX085-5’s design. Standard safety equipment includes anti-drop boom and arm valves, overload warning systems, rear-view camera, LED working lights, ROPS-certified cab protection, and Kubota’s anti-theft immobiliser system. The triple-opening bonnet and grouped maintenance components allow quick and convenient servicing, reducing downtime and simplifying routine inspections.

With outstanding hydraulic performance, advanced operator technology, compact dimensions, and robust construction quality, the Kubota KX085-5 is built to deliver reliable productivity and long-term value across a wide range of demanding excavation applications.
