Motor Grader - 3D

We make sure the investment you make today will work for you in the future. Topcon’s building block design allows you to add new sensors or technologies to your system such as mmGPS and Networks as they become available without having to buy a whole new system.

Features & Benefits

  • Rugged color touch-screen control box displays blade position and distance to design
  • Real-time cut/fill mapping - move material only once
  • Backwards compatible with existing Topcon MC systems
  • Enter off-sets easily for cutting sub-grade
  • Increase grading productivity significantly
  • Reduce staking on jobsite almost entirely
  • Control materials to your advantage
  • Complete projects on time or ahead of schedule


For road building, site work, contour grading, or any other complex surface grading requirements, Topcon’s 3D-GPS+ will put more money to your bottom line  where it counts. With the reality of nearly eliminating grade stakes, providing unmatched material control capability, and the simplest user interface in the industry, you are sure to integrate Topcon 3D technology successfully into your business.

What is Stakeless Grading?

What’s the greatest source of delay on your jobs? Placing, and replacing stakes has been a necessary headache in construction, until now. GPS machine control combines two fantastic technologies, Satellite Positioning and Digital 3D models, so that your machine operators can see themselves moving on the site plan in real time, with cut/fill information constantly displayed anywhere. This gives them much more information than stakes can, and faster. And now, one grade checker can work the whole site because the machines are independent. Everyone knows exactly where they are, and they have all the job information at their fingertips! That’s stakeless grading!

GPS + GLONASS + Galileo

Topcon was the first to offer the dramatic increase in performance of GPS+, our unique combination of both the American GPS system and the Russian GLONASS satellite system. Complex technology, but a simple result: unbeatable performance and uptime. Now, you don’t need to sit idle waiting for enough satellites to be visible to your machines. You won’t need to think about satellites hardly ever, because Topcon is making sure you get the performance you demand. And our new G3 technology reads not only all current satellites, but future systems as well, so that you can buy a system today and get cutting edge performance for years. Only from Topcon.


Topcon Motor Grader mmGPS System


Make mmGPS work for you and be the solution for the challanging jobsites when high precision elevations are required. Precision staking becomes a one man operation with this Topcon GPS system.

Features & Benefits

  • World's first millimeter accurate GPS system, up to 300% more accurate than standard GPS
  • Laser Zone transmitter provides precise vertical measurement area 600m in diameter, 10m in height
  • Works with existing Topcon GPS+ systems
  • Multiple rover support machine or pole mounted
  • Lower investment - one system works for rough and finish grade
  • Grade to tighter tolerances and eliminate high cost material overruns
  • Finish grade 24/7 even with minimal satellite coverage

Millimeter GPS+ transforms GPS into the perfect tool for blue-topping and other fine tolerance work.

With Millimeter GPS+, the days of lost productivity, using stringlines or running manually off of hubs, are over.  Millimeter GPS+ combines the advantages of laser (multi-user & high vertical accuracy) with GPS (multi-user & 3D) into one versatile and easy to use system.

This patented technology improves grading accuracy up to 300% over existing 3D-GPS machine systems.  Unlike any other laser technology, the PZL-1 transmitter sends out a wall of light 33’ tall and up to 2000’ in diameter. Simply add the PZS-MC machine control sensor or PZS-1 rover sensor to your existing GPS+ system, and watch your GPS vertical accuracy shrink down to numbers you never imagined before.

Need more coverage?

You can link up to four PZL-1 transmitters for a total of 8000’ horizontally and 132’ vertically. Unlike with total stations, multiple machines and man rovers run off one transmitter, there is no limit!


Topcon Motor Grader LPS System


Rather than GPS signals, Topcon’s LPS-PS utilizes a high-accuracy, fast auto-tracking Total Station to maintain machine position information via machine mounted prism.

Features & Benefits

  • Topcon XTRAC prism tracking technology 
  • 20Hz update rate
  • Long range 2.4Ghz interference free radio
  • Insures all your jobsites have 3D control 24/7 High accuracy for tight tolerance projects Simple & fast conversion between LPS and GPS communications
  • GX-60 control box runs LPS, GPS and all 3D controls
  • Visual graphic on display for acquiring lost beam
  • Same robot used with Pocket 3D as layout/grade checking tool

Robotic Based Local Positioning Grade Automation

As it tracks the machine/prism, the Total Station maintains exact machine position / grade information per an internally loaded digital site plan. Grade adjustments are then transmitted to the machine 20 times per second via radio from the Total Station. It’s simple, reliable, and the perfect alternative when GPS reception is limited. Compatible with Topcon’s machine mounted GPS grade control components, it’s a quick and easy change to swap LPS for GPS and keep productivity to a maximum.

Based on our popular PS robotic total station platform, the LPS-PS offers high accuracy position control over your entire site, to within a few millimeters. Topcon’s new robotic total stations utilize the patented XTRAC technology to track machines at speeds up to 35 MPH. Machine and blade position is updated 20 times per second, fast enough to meet the tightest jobsite specs. This speed and accuracy makes difficult and complex sites easy to grade.

Switching existing GPS+ systems to LPS-PS is simple. Put up the total station on a control point, place a 360° prism on the vibration pole and a RS-5 radio in the cab and you’re ready to go to work. The robotic total station locates the 360° prism and sends the X, Y, Z position of the cutting edge to the machine via radio link. The operator can now work as before, but with very high accuracy. Obstructions to the sky no longer hinder your work or slow you down. Whatever the conditions are at the job, Topcon LPS-PS can help you get it done fast and accurately.

Sensor Freedom

Topcon has a long history of leadership in machine control. We build a wide variety of sensors, each of which has applications where it shines out as the best choice. Want to use a laser? A sonic system? Need the high accuracy of a total station? Want to blend your sensors on a single machine? Only Topcon allows what we call Sensor Freedom: you choose the sensor type(s) best suited to your application, plug them in to your Topcon machine control system, and off you go. Topcon’s component-based system takes it all in stride, so you can too.
