Precision Grade Control Built for Compact Equipment
The Leica LMR240 (SKU: 773569) is a purpose-built laser machine receiver designed to bring reliable, real-time grade control to the tightest cab environments on the jobsite. Whether you're running a backhoe, mini-excavator, or skid steer, the LMR240 delivers the grade-line feedback operators need to dig accurately on the first pass — reducing rework, cutting material costs, and keeping projects on schedule. Its compact housing and intuitive display make it a natural fit for small equipment fleets where space is at a premium but precision cannot be compromised.
Overview & Jobsite Applications
The LMR240 is engineered specifically for operators of smaller excavation machinery working in residential subdivisions, utility trenching, landscaping grading, and light commercial excavation. Unlike full-size machine control systems built around large equipment, the LMR240 scales down the form factor without scaling down the performance. It pairs with rotating laser levels to give operators a constant reference to the grade plane, displaying above-grade, on-grade, and below-grade positions in real time directly in the cab.

Key Features
- Compact form factor designed to mount cleanly on backhoe and mini-excavator stick arms without obstructing operator sight lines
- Real-time LED grade display provides instant above/on/below grade indication so operators react immediately without stopping to check grade manually
- Numeric offset readout shows exact cut or fill amount in inches or millimeters, eliminating guesswork on fine-grading passes
- IP67-rated housing withstands direct water spray, mud, and dust exposure common on active excavation sites
- Wide laser detection window captures the rotating laser beam even when the machine is moving, reducing signal loss during dig cycles
- Audible and visual grade alerts keep operators informed without requiring constant display monitoring during repetitive digging
- Simple field calibration allows crew members to set and verify grade reference without specialized training
- Long battery life reduces downtime for battery changes during extended shift operations
Job Applications
Residential Foundation Excavation: Backhoe operators use the LMR240 to hit precise footing depths on residential builds, reducing over-excavation and the associated backfill costs that eat into project margins.
Utility Trenching: Mini-excavator crews installing water, sewer, or conduit lines rely on the LMR240's real-time grade feedback to maintain consistent trench bottom elevations required by municipal specifications — pass after pass, without manual checks.
Landscape Grading & Drainage: Skid steer operators finishing drainage swales and yard grading use the LMR240 to achieve specified positive drainage slopes quickly, reducing the back-and-forth typically required to reach acceptable surface grades.
Light Commercial Site Work: Site prep crews working on parking lots, small commercial pads, and access road subgrades use the LMR240 to establish consistent subgrade elevations before base material placement, keeping paving crews on schedule.

Frequently Asked Questions
- Is the Leica LMR240 compatible with non-Leica rotating lasers?
- The LMR240 is optimized for use with Leica Rugby series rotating lasers but is designed to detect standard 635nm red beam rotating lasers from most major manufacturers. For guaranteed performance and full feature compatibility, pairing with a Leica Rugby laser is recommended. Contact Express Tools for compatibility verification with your specific laser model.
- Can the LMR240 be used on a full-size excavator?
- The LMR240 is engineered primarily for compact equipment — backhoes, mini-excavators, and skid steers. While it can physically be mounted on larger equipment, contractors operating full-size excavators on grade-sensitive work typically benefit from a larger-format receiver or a more advanced machine control system. Our team can help you select the right receiver for your equipment class.
- What is the detection range of the LMR240?
- The LMR240 features a wide vertical detection window to capture the rotating laser beam across the range of positions encountered during normal dig cycles. The effective working range depends on the output power of the paired laser; with a Leica Rugby series laser, typical working ranges extend to several hundred feet under standard field conditions.
- Does the LMR240 come with a mounting bracket?
- Mounting hardware availability may vary by configuration. Express Tools can confirm what is included with your specific order and recommend the appropriate stick-arm mounting bracket kit for your backhoe or mini-excavator make and model. Call or chat with our team before ordering to ensure you have everything needed for a same-day installation.
