Leica LMR360R Machine Control Receiver with Clamps
The Leica LMR360R (6003354) is a professional-grade machine control receiver engineered for contractors who demand precision on every cut. Bundled with mounting clamps for fast jobsite installation, this receiver brings real-time grade feedback directly into the operator cab — eliminating ground crew check shots and accelerating earthwork production. Whether you're rough grading a subdivision or finishing a highway subbase, the LMR360R delivers the accuracy and durability required on modern machine control systems.
Product Overview & Jobsite Applications
Designed to work seamlessly with rotating laser systems, the LMR360R mounts on the mast of a dozer blade, motor grader, or excavator arm and continuously communicates elevation data to an in-cab display or machine control box. Its 360-degree reception window captures the laser plane from any orientation, so operators never lose signal during turns or tight passes. The integrated tilt indication feature makes this receiver particularly valuable on cross-slope and dual-fall applications where blade angle is constantly changing. The ruggedized housing is built to withstand vibration, dust, and moisture common to heavy earthwork environments.

Job Applications
Dozer Rough Grading: Mount the LMR360R on the dozer mast and connect to your in-cab control box for automated blade height adjustment across large clearing and mass earthwork operations — reducing over-excavation and material waste.
Motor Grader Finish Work: The tilt sensing capability makes the LMR360R ideal for motor graders cutting crowned roadways or parking lot pads where both cross-slope and longitudinal grade must be maintained simultaneously.
Excavator Trenching: Use the receiver on an excavator mast to confirm trench invert depth in real time, eliminating repeated manual check shots and keeping utility installation moving at pace.
Subbase & Subgrade Preparation: Whether prepping for concrete flatwork or asphalt paving, the LMR360R ensures consistent subgrade elevation across the entire site, improving compaction uniformity and reducing surface prep costs.

Frequently Asked Questions
- Is the Leica LMR360R compatible with non-Leica rotating lasers?
- Yes. The LMR360R is designed to receive standard rotating laser signals and is compatible with most major brands including Spectra, Topcon, and Trimble rotating lasers, in addition to the full Leica Rugby and Roteo series. Always verify signal frequency compatibility with your specific laser model before pairing.
- What machine control display boxes work with the LMR360R?
- The LMR360R outputs a standard grade signal compatible with Leica's own GR25 display as well as popular aftermarket machine control panels. Consult the receiver's output specifications and your display manufacturer's input requirements to confirm compatibility. Express Tools technical staff can assist with pairing recommendations.
- Does the LMR360R require calibration on installation?
- The LMR360R is factory calibrated and ready for use out of the box. However, verifying the mounting plumb and confirming the laser plane elevation against a known benchmark before beginning grading work is always recommended as a best practice for any machine control setup.
- What is included with the LMR360R 6003354 kit from Express Tools?
