Intelligent Machine Control machines have the following advantages over dozers with external grade control systems:

  • No Cables 
    • No coiled cables between machine and blade    
  • Innovative 
    • Automated operation from rough dozing to finish grade
  • No Climbing 
    • GNSS antenna and mast removed from blade    
  • Intelligent 
    • New dozing mode, load control performance features
  • No Connections 
    • No daily connections required between machine and blade    
  • Integrated 
    • Standard factory installed integrated system
       

• Automated Blade Control, from Rough Dozing to Finish Grade. Straight to Grade.

  1. Blade moves to target surface until load reaches a preset level.
  2. The blade automatically raises to minimize track slip.
  3. Should the load decrease, blade will lower to re-load blade to an optimum level.
