Grade Control Components

Doesn't your machine deserve the best? Trimble makes long lasting, accurate components for your grade control system, with proven quality you can depend on.

  • CB460 Control Box

    The Trimble CB460 Control Box is the premium display for all machine types in the Grade Control System portfolio. The CB460 offers the same key features as the CB450, plus:

    • A large, easy-to-read 7” (17.78 cm) full-color LCD display
    • Support for external lightbars
    • Faster data transfer via Ethernet connection
  • CB450 Control Box

    Designed for use in harsh construction environments, the Trimble CB450 Control Box gives the operator a full-color graphical display for easy viewing and guidance to grade. Features include:

    • 4.3” (10.9 cm) full-color LCD display with adjustable backlight controls
    • Audible tones for real-time grade guidance or warnings and alerts
    • Four LED lightbars to provide grade guidance at a glance
  • MS995 GNSS Smart Antenna

    The MS995 contains an integrated GPS+GNSS receiver, antenna, and isolation system all in a single, durable housing. It uses the advanced Trimble RTK engine for faster initialization times when satellite lock is lost and enhanced performance near obstructions.

  • MS975 GNSS Smart Antenna

    The MS975 offers a cost-effective alternative for contractors who need a highly accurate GPS/GNSS receiver at a lower price point. It is optimized for cab or machine body mount only.

  • SPS Series Universal Total Stations

    Trimble SPS Series Universal Total Stations can be used for even greater accuracy when performing fine or finished grading, with blade guidance to 2-5 millimeters (0.007 to 0.016 feet).

  • SNR On-Machine Radios

    Rugged Trimble on-machine radios offer a modernized platform for communicating with Trimble Universal Total Stations or with a fixed GNSS base station. Available in:

    • Single-band 450 MHz, 900 MHz, and 2.4 GHz
    • Dual-band 900 MHz + 2.4 GHz and 450 MHz + 2.4 GHz
  • SR300  Laser Receiver Mast 

    When improved vertical accuracy is needed, GNSS systems can be enhanced with the Trimble SR300 Laser Receiver Mast with a GNSS Smart Antenna for blade control to 3-6 millimeters (0.01 to 0.02 feet).

  • LR410 Laser Receiver

    The LR410 is mounted to an electric mast on the blade and connected to the machine hydraulics to control lift to an accuracy of 3-6 millimeters (0.01 to 0.02 feet).

  • GL700 Series Grade Lasers 

    Spectra Precision Laser GL722 and GL762 Series Grade Lasers provide years of durable, precise machine guidance with GCS900 2D Grade Control Systems, the GCSFlex Grade Control Systems and laser-based compact machine installations. Ideal for site preparation, trenching and pipe laying, fine grading and road construction, the GL700 lasers can help you get to grade faster with more accuracy.

  • ST400 Sonic Tracer

    The ST400 is mounted to the blade and uses a physical reference such as curb and gutter, stringline, existing or previous pass as an elevation reference.
