The Trimble 3D Grade Control System maximizes excavator performance. Whether grading simple trench and slopes or complex design surfaces and alignments the operator can get to grade faster, without sacrificing accuracy or quality of the final graded surface.


The 3D system is well suited for mass excavation applications such as:

Land reclamation
Dam and reservoir construction
New infrastructure projects
Landfills and waste deposits
Residential and commercial sites
Road construction
Finished slope work
Dredging and waterways


Single GNSS

Measures the position and slope of the blade and compares that to design data for rough grading and mass excavation on complex design surfaces


Measures the exact position, cross slope and heading of the blade for rough grading and mass excavation on steep slopes and complex design surfaces

Universal Total Stations

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
