The Topcon LS-B10W-PRO Machine Control Kit (312660111) delivers professional-grade elevation control for heavy equipment operators who demand accuracy and real-time feedback from inside the cab. Combining the rugged LS-B10W wireless machine receiver with the RD-100W remote wireless display, this kit eliminates the need for operators to crane their necks or step off the machine to read grade — the display mounts cleanly in the cab and communicates wirelessly with the receiver mounted to the blade or screed post. Whether you're cutting subgrade, spreading fill, or trimming finish on a road base, this system keeps you on grade and on schedule.
Overview & Jobsite Applications
The LS-B10W-PRO Kit is engineered for contractors running rotating laser setups on earthwork, site development, and civil construction projects. The LS-B10W receiver captures the laser plane signal and transmits grade status wirelessly to the RD-100W display — no trailing cables, no dashboard clutter. The bright LED display gives operators clear on-grade, cut, and fill indicators even in direct sunlight, keeping productivity high across long work cycles. This kit is ideal for single-slope and dual-slope laser systems and integrates with a wide range of Topcon rotating lasers.

Job Applications
Road Base & Subgrade Preparation: Set your rotating laser to the design slope and let the LS-B10W-PRO guide your motor grader or dozer blade to consistent grade across the full width of the roadbed — cut depths and fill heights displayed live in the cab.
Building Pad & Site Grading: Control cut-to-fill operations on large commercial pads where operators need continuous elevation feedback without stopping to check grade stakes. The wireless display keeps the operator informed pass after pass.
Trench Bottom & Utility Work: Mount the receiver on an excavator thumb or trench box rod for precise invert control. The remote RD-100W keeps the operator on-depth without a ground guide in the trench.
Parking Lots & Drainage Slopes: Achieve tight tolerance positive drainage slopes on asphalt and concrete paving prep work. The adjustable deadband setting lets crews dial in the sensitivity required for finish-grade tolerances.

Frequently Asked Questions
- Does the RD-100W display need to be cabled to the LS-B10W receiver?
- No. The RD-100W communicates wirelessly with the LS-B10W receiver, with a reliable range of up to 100 meters. This eliminates any need to run cables through the cab or along the blade mast, making setup faster and reducing wear points on the system.
- What rotating lasers are compatible with this kit?
- The LS-B10W receiver is compatible with most Topcon rotating lasers in the RL-H, RL-SV, and RL-200 series, as well as many third-party rotating lasers operating in the 635–690 nm wavelength range. Confirm compatibility with your specific laser model before purchase — our team at Express Tools can assist.
- Can this kit be used on both a dozer and a motor grader?
- Yes. The universal mounting bracket included with the kit accommodates blade mast installations on most dozers and motor graders. The compact, rugged design of the LS-B10W makes it well-suited for the vibration and exposure conditions of both machine types.
- Is this kit suitable for dual-slope grade control applications?
- The LS-B10W-PRO Kit is designed for single-receiver, single-axis grade control. For full dual-slope or 3D machine control, a more advanced control system would be required. However, for single-slope rotating laser setups — which cover the vast majority of earthwork grading tasks — this kit delivers professional accuracy and dependable performance.

Can this kit be used on both a dozer and a motor grader?
Yes. The universal mounting bracket included with the kit accommodates blade mast installations on most dozers and motor graders. The rugged, compact design of the LS-B10W handles the vibration and environmental exposure of both machine types reliably.
Is this kit suitable for dual-slope grade control applications?
The LS-B10W-PRO Kit is optimized for single-receiver, single-axis grade control using a rotating laser. For full dual-slope or 3D GPS machine control, a more advanced system would be needed. For single-slope earthwork grading — the majority of dozer and grader applications — this kit delivers professional accuracy.
