Versatility

  • Excellent machine balance, power-to-weight-ratio and VPAT blade for general dozing and fine grading.
  • For dozing productivity, updated SU configuration follows the design of larger Cat dozers with front-mounted lift cylinders to provide more breakout force and stability.
  • Forestry and landfill arrangements offer added features and guarding to take on especially harsh environments.

Ease of Operation

        
  • Updated cab, with an integrated Roll Over Protection Structure (ROPS) and 15° offset seat, offers greater all around visibility.
  •     
  • Improved cab pressurization helps keep dust out for a cleaner operating environment.
  •     
  • New Liquid Crystal Display (LCD)* places machine data, settings menus and more conveniently in front of the operator.
  •     
  • Low effort electro-hydraulic controls* offer precise response and facilitate GRADE technologies.
  •     
  • Choose the best speed for your job: 5-speed mode is easily adjusted with throttle dial.
  •     
  • Bi-directional control to preselect forward/reverse gears – automatically downshifts to the most efficient gear based on load for reduced operator effort and improved efficiency.
