The Leica MC1 is a GNSS-based machine control system for dozers and graders that uses the iCON grade sensor and Leica base station to achieve 20mm 3D blade accuracy.
Leica MC1 — Complete Specs, Manual & Guide
Category: Machine Control | Brand: Leica | Model: MC1
The Leica MC1 is Leica Geosystems' production machine control platform, using GNSS positioning and the proprietary iCON grade sensor to deliver precise blade control on dozers, graders, and excavators. The MC1 platform operates on Leica's iCON field software and integrates with Leica iCON site for machine-to-office communication.

Frequently Asked Questions — Leica MC1
What accuracy does the Leica MC1 achieve?
The MC1 achieves 20mm 3D blade accuracy with RTK corrections from a Leica GNSS base station. This meets industry standards for finish grading on construction earthworks.
What machines is the Leica MC1 compatible with?
The MC1 system is designed for Cat, Komatsu, Volvo, and John Deere dozers and motor graders, as well as excavators with the appropriate excavator-specific sensor kit. Machine-specific mounting brackets and calibration data are required.
What is the difference between Leica MC1 and Topcon 3D-MC2?
Both systems achieve similar 20-25mm 3D blade accuracy with GNSS. Key differences include field software (Leica iCON vs Topcon MAGNET Earthworks), design file formats, and service networks. Equipment dealers often stock one brand; choose based on your dealer's support capabilities.
How does design data get into the Leica MC1?
Design surfaces are prepared in Leica iCON office software and transferred to the machine display via USB or the iCON site WLAN network. The MC1 display reads LandXML and Leica native surface formats.
