MACHINE FEATURES
Retractable Undercarriage
The undercarriage retracts to 750 mm for narrow passages and extends to 990 mm for a wider working stance. The retractable blade can be adjusted to suit the working configuration.
Hydraulic Pilot Controls
Standard hydraulic pilot joysticks are positioned beside the operator’s seat, providing smooth, precise control during digging and bucket positioning.
Boom Swing
The boom swings 55° left and 55° right for offset digging beside walls and obstacles in confined spaces.
