Yes, I would like to receive future marketing communications (such as email) from Caterpillar Inc., its affiliates and subsidiaries worldwide and the Caterpillar dealer network. Regardless of whether you decide to receive these marketing communications, Caterpillar will continue to send service/transactional messages, including those that have to do with any accounts that you may have with us.


Cat® Grade with 3D integrates traditional machine control and guidance with machine hardware and software from the factory in order to improve productivity, usability, reliability, job site safety and machine value. It is another example of Caterpillar innovation and technology leading the way for our customers to be more successful.

3D systems use Global Navigation Satellite System (GNSS) satellite technology to deliver precise blade positioning and location information to the operator in the cab. Using machine-mounted components, position sensing hydraulic cylinders, an off-board GNSS base station, and Real Time Kinematic (RTK) positioning accuracy, these systems provide the information necessary to determine precise blade positioning with centimeter level accuracy. The system computes the positioning information on the machine compared to the position of the cutting edge relative to the design plane and delivers the information to the operator via the standard in-cab display. All the information the operator needs to complete a job is delivered to the cab display, resulting in a greater level of control. Cat Grade with 3D also provides overcut protection and linkage to additional Caterpillar exclusive features like AutoCarry™, Automatic Ripper Control and Load Assist. These systems are ideal for high production dozing and cutting complex 3D contours, such as highway projects.

  • GRADE with 3D is built right in at the factory – components are protected and optimized on the machine for durability and quick response.
  • GNSS antennas are mounted on top of the cab, so there are no masts or cables on the blade – nothing to remove at the end of the day.
  • Grade control display is fitted into the dash, putting the design plan right in front of the operator.
  • Control buttons are integrated into the implement control joystick, so the operator can keep their hands on the controls, even when turning automatics on and off.
  • GRADE with 3D is ordered with the machine and supported by your Cat dealer and SITECH® technology partner.


  • Cat Grade Control 3D automatically adjusts blade movements – both lift and tilt – as you follow the design.
  • No additional inputs are required from the operator, except steering. No grade checking or stakes to follow. Simply lower the blade to smoothly cut to plan, raise to disengage.
  • Cat Grade Control 3D helps experienced operators work more productively and maintain accuracy over long shifts.
  • Operators with less experience become proficient and get to design plan faster.
  • Reduces operator inputs by up to 80%


  • Cat GRADE with 3D works in both production dozing and fine grading applications.
  • Optimized to work with other dozing features, like AutoCarry™, which maximizes blade loads for ground conditions to improve load capacity and reduce track slip. This means you get full blade loads and smoother grades, every pass.
  • Includes AccuGrade™ Ready Option (ARO) so you can add laser or UTS control as needed.
