Grade Control for Motor Graders

One and Done.

Leave a finished grade the first time, every time.


Make More Progress. And Fewer Waves.

Trimble Earthworks Grade Control Platform helps operators of all levels leave a quality surface in their tracks. Trimble Earthworks for motor graders is more than future forward. It’s fast forward. The next generation system gives you a first-pass finish that’s second to none.

Trimble Earthworks is now available in a subscription model with flexible terms to modernize your equipment with no large upfront cost.

Trimble Earthworks Software

Trimble Earthworks for Motor Graders is an entirely new grade control software application that is intuitive, easy-to-learn and runs on the Android operating system.

Trimble Dual GNSS

Trimble, a leader in precision measurement technology, pioneered the Dual GNSS solution to meet the needs of the construction industry. Watch the video to see how it works and why you need it!

Configuration Options for Motor Graders

Product Applications Configurations Description
  • Highway and railway construction
  • Airport construction
  • Concrete pours and slab placement
  • Residential and commercial site construction
Single GNSS Measures the position and slope of the blade and compares that to design data for fine grading on complex design surfaces
3D   Dual GNSS Measures the exact position, cross slope and heading of the blade for fine grading on steep slopes and complex design surfaces
3D   Universal Total Station (UTS) Total station based system for extreme accuracy for lift and layer control, material monitoring, or where GNSS is not the ideal solution because of overhead obstructions
  • Road and highway projects
  • Land reclamation projects
  • Dam and reservoir construction
  • New infrastructure projects
Cross-slope Only Cross-slope control system to be used on motor graders for fine grading work for road maintenance, ditches and slope work
2D   Single Elevation Plus Cross-slope Single control system uses a laser or sonic receiver to control the lift of the machine blade and the cross-slope for flat, slope work, and finished grading
2D   Dual Elevation Dual control system that uses a laser receiver and a sonic tracer for higher accuracy lift control. Blade edge can be controlled independently or linked

3D Grade Control for Motor Graders

Trimble 3D grade control can be installed on motor graders to put the site plan - design surfaces, grades and alignments - inside the cab.


  • Accurately measure the position and blade slope with the single GNSS antenna configuration
  • Measure the exact position, cross slope and the heading of the blade with dual GNSS

Finished Grade

  • Achieve finished grade to millimeter accuracy with fewer passes
  • Place finished grade materials more accurately and in a shorter time period, keeping material costs to a minimum and realizing better profits

2D Grade Control for Motor Graders

2D grade control systems from Trimble are an excellent first investment for contractors new to construction technology.


  • Measure the lift and tilt of the blade with a single laser and laser receiver
  • Measure the slope of the blade by adding another laser receiver or a slope sensor
  • Get to grade more accurately and quickly with in-cab elevation and slope guidance
  • Upgrade to a 3D grade control system as your organization grows

Finished Grade

  • Achieve tight tolerances and a smooth finished grade with precise vertical guidance.
  • Calculate the cross-slope of the blade using two angle sensors and a rotation sensor
  • Add a laser receiver or a sonic tracer to measure elevation 
  • Trace stringline, previous pass, or curb and gutter with a sonic tracer
