CAB

Materials and specifications are subject to change without prior notice

One-seat cab with double panes provides excellent equipment and working areas visibility irrespective of ambient air temperature. The cab is equipped with ventilation system and dependent and independent heaters and with a vibroprotective seat and sound-proofing lining. The controls meet ergonomic requirements and offer ease of operation and access.

Engine control is performed by the pedal to be fixed at chosen engine speed rotation. Gear and directional changes are performed by one multifunctional electrical control lever (joystick). Friction clutches and brakes are controlled by two levers. Emergency stop is achieved by pressing the brake penal. Blade and ripper control is performed by separate hydraulic joysticks. All controls are performed from the operator's seat providing fatigue-free operation throughout the working shift.
