The Topcon LS-B10 Machine Control Laser Receiver (312660101) delivers accurate, automated grade control for heavy equipment operators working on demanding earthmoving and grading projects. By detecting rotating laser beam signals and transmitting real-time cut/fill commands to the machine's blade control system, the LS-B10 eliminates guesswork, reduces rework, and helps crews hit grade faster on every pass. Whether you're running a dozer on a road base or a grader on a subdivision pad, the LS-B10 is a reliable, contractor-proven solution built for the rigors of daily site work.
Product Overview
The LS-B10 is Topcon's entry-level machine control laser receiver designed for non-wireless, direct-cable integration with compatible machine control systems. It mounts to the blade or mast of your equipment and continuously reads the elevation of a rotating laser plane, sending guidance signals to the control box to automatically raise or lower the blade. The result is consistent, repeatable grade accuracy across the entire cut — with minimal operator intervention. Ideal for site prep, road construction, land leveling, and agricultural grading applications where single-plane laser control is sufficient.

Job Applications
Site Preparation & Pad Grading: Set your rotating laser to finished floor elevation and let the LS-B10 guide the dozer blade automatically — reducing passes and keeping material quantities tight from the start.
Road Base Construction: Achieve consistent subgrade and base course elevations along road alignments without constant grade checking, improving production speed and conformance to design tolerances.
Land Leveling & Drainage: Establish positive drainage slopes on agricultural fields, parking lots, and commercial sites with repeatable accuracy across large open areas.
Rough Cut Earthmoving: Use the LS-B10 to bring large earth-moving operations close to final grade efficiently before fine grading crews follow behind, saving time and fuel on bulk cut/fill operations.

Frequently Asked Questions
- Does the Topcon LS-B10 require a separate machine control display?
- Yes, the LS-B10 is a receiver only and must be used in conjunction with a compatible Topcon machine control display or control box, such as the CB-410, which processes the receiver's signals and drives the automatic blade control valves.
- Is the LS-B10 compatible with any rotating laser, or only Topcon lasers?
- The LS-B10 is optimized for use with Topcon rotating lasers but can detect the beam from most standard 635nm rotating lasers. For guaranteed system performance and integrated diagnostics, pairing with a Topcon rotating laser such as the RL-H5A is recommended.
- What is the difference between the LS-B10 and a wireless machine control receiver?
- The LS-B10 uses a direct cable connection to the machine control display, while wireless receivers transmit grade data via radio signal. The non-wireless design of the LS-B10 offers a simpler, interference-free setup and is a cost-effective choice for single-machine operations where wireless range is not required.
- Can the LS-B10 be used on a motor grader as well as a dozer?
- Yes. The LS-B10 is suitable for use on dozers, motor graders, scrapers, and other blade-equipped machines. Ensure the appropriate mast mounting hardware is used for your specific equipment configuration for secure, vibration-resistant receiver positioning.
