The 2D-MC from Topcon Positioning Systems is an automatic grade control solution for compact track loaders. The 2-D machine control system is designed to be installed directly onto select grading attachments, connecting directly to the machine’s controls and an easy-to-use wireless display to work with familiar rotary laser technology to provide simplified operational visibility, with all the information needed to hit target grade with greater precision.

Ideal for slope work, sidewalk grading, road base and drain rock replacement, parking lots, sports fields, landscaping, flat pads, indoor work, concrete site prep and more, the system adapts to different grading attachments for compact equipment, leveraging the performance of machine control technology with the accuracy of laser positioning.

Using laser receivers to work with rotary lasers, if a user is familiar with rotary lasers, no additional tooling or training is needed to determine the correct grade for the grading attachment.

The system can be customized by using either a dual-laser receiver setup for elevation at both edges of the blade, or a single-laser receiver with a highly accurate dual-axis tilt sensor for elevation and slope determination. It is designed to fit right in with many of the tools already implemented, and the software can be used on Android devices like a CT8X2 tablet, providing a familiar interface.

The app has a simple user interface with a straightforward progressive grade arrow indication. This provides the operator with an easy-to-see “work completed” and “work remaining” visual. With adjustable increment/decrement elevation control right from the machine’s joystick, set/match elevations/slopes, valve adjustment capabilities, automatic updates and simple menus, an operator can get up and running on the system in very little time.
