Machine Mounted Laser Receivers
Seven machine mounted laser receivers covering every earthmoving application, from basic excavator and blade work through to wireless in-cab display with blade tilt and plumb swing indication. Choose by mount type, whether you need an in-cab display, and how much information you want from the seat.
Boost your Earthmoving efficiency. From the comfort of your cabin.
A machine mounted laser receiver is a heavy-duty sensor that bolts or clamps onto your excavator arm, blade pole, dozer or skid steer and reads the beam from a rotating laser. It picks up the laser plane as your machine moves, then tells you in real time whether your cutting edge is above, below or bang on grade. No guessing. No jumping in and out of the cab to check a staff. Just a row of bright LEDs you can read at a glance while you work.
These units are purpose-built for earthmoving. Where a handheld receiver is designed for a person standing still, a machine receiver is built to handle constant vibration, mud, dust and the kind of knocks that happen every day on a working site. The LED indicators are deliberately sized for visibility at distance, and the accuracy settings are matched to what machinery can actually achieve — typically within 5 to 25mm depending on the job. If you are cutting batters, laying subgrade, trimming pads or excavating to invert, a machine receiver gives your operator a constant height reference without breaking rhythm.
Redback machine receivers are built around a metal chassis, rated to IP66 or IP67, and carry a 250mm or 260mm reception window with four sensor bands covering 360 degrees. The internal NiMH rechargeable battery charges from 240V mains or straight off your machine via a 12V or 24V charge cable. All models work with any red beam rotating laser, Class 2 or Class 3, regardless of brand. Options range from a basic receiver with on-unit LED readout through to the MR825WD, which adds wireless in-cab display, blade tilt and plumb swing indication with no cables to run.
- 250mm to 260mm sensor window for reliable beam detection on moving machinery
- 360-degree coverage with four sensor bands, no blind spots as the machine swings
- IP66 or IP67 rated, built to work in real conditions not just a workshop
- Internal rechargeable battery, top it up from the machine’s own 12V or 24V supply
Compatible With Any Red Beam Rotating Laser
Every Redback machine receiver works with Class 2 or Class 3 red beam rotating lasers, whatever brand is already on your site. If you need a laser to pair with your receiver, see our range of compatible rotating lasers.
Consistent Heights & Grades every time
Not only will the machine receiver give you accurate levels anywhere on your jobsite, they’ll also work grade with grades! Whether it’s single grade for trenches or dual grade for roads/drainage, machine receivers can handle it.
Keep Your Eyes in the Cab
Display models bring the height reading inside the cabin via a wired 10m cable or wireless RF connection, so your operator never has to crane out the window to check grade. Less distraction, better accuracy, faster cuts.
How to Use a Machine Mounted Laser Receiver
Set Your Rotating Laser at a Known Datum Height
Set up your red beam rotating laser on solid ground clear of the work area and switch it to rotate. Establish the instrument height above a known datum or RL, using a staff and handheld receiver if needed. This spinning laser plane becomes your reference grade for the entire job.
Mount the Receiver on Your Machine at the Target Height
Fix the machine receiver to your excavator dipper arm, blade pole or machine frame at the height that matches your target grade. Use the magnet mounts for steel excavator surfaces or the clamp mounts for round pole setups on dozers, skid steers and box blades. The 250mm sensor window gives you plenty of margin as the machine moves through the beam.
Cut or Fill to Match the Grade Shown on the Receiver
Watch the LED indicators on the receiver, or on the in-cab display if you have a D-series or MR825WD model. When the on-grade indicator lights up, your cutting edge or blade is at the correct level. Raise or lower until you hit on-grade, then work across the site maintaining that reading. It is that simple.
Pair your Receiver with a Laser Level
A machine mounted laser receiver needs a compatible red beam rotating laser to work, opt for a grade laser for accurate trenches & drainage.
Machine Mounted Laser Receiver FAQs
It comes down to three things: how your receiver will mount to the machine, whether you want a display inside the cab, and how much information you need while you work. For excavators, a magnetic mount receiver like the MR706 or MR706D attaches directly to the dipper arm. For machines running a pole-mounted setup, such as a dozer or box blade, a clamp mount like the MR708 or MR708D is the right fit. If you run multiple machine types and want one receiver that does both, the MR710 or MR710D includes both magnet and clamp mounts in the kit. The D models in each pair add a wired in-cab display so you can read height without looking out the window. If you want wireless, blade tilt and plumb swing reading all in one unit, the MR825WD is the premium option.
All MR7 series receivers offer two accuracy settings. Fine mode gives you plus or minus 3 to 5mm, which is tight enough for finished grades and concrete prep. Coarse mode opens up to plus or minus 5 to 25mm, which suits bulk earthworks where you want faster indication without the receiver constantly hunting. The MR825WD has three settings: plus or minus 5mm, plus or minus 10mm, and plus or minus 20mm. Use fine mode when precision matters and coarse mode when you just need to move dirt efficiently.
All Redback machine receivers work with red beam rotating lasers rated Class 2 or Class 3. They are not compatible with green beam lasers or line lasers. The MR825WD has a detection range of approximately 200 metres radius when paired with a Class 3 red beam laser, which covers most excavation and earthmoving sites. If you need help choosing a compatible laser, have a look at our red beam rotating lasers category.
You want a magnetic laser receiver for excavator work. The magnet mount attaches directly to the dipper arm, so the receiver travels with the stick and stays in the beam as you dig. The MR706 is the entry point for excavator use, with LEDs on the receiver itself. The MR706D adds a wired in-cab display so the operator reads height from inside the cab without craning their neck. If you also want blade tilt and plumb swing indication for more accurate digging, the MR825WD is the premium choice and includes both magnetic and clamp mounts.
For a skid steer, dozer or box blade setup, you need a clamp mount receiver that attaches to a 40 to 50mm pole or tube. The MR708 is the laser receiver for skid steer and blade work without a cab display. The MR708D adds the wired in-cab display, which makes a real difference when you are grading and need both hands on the controls. If you run a mix of machines, the MR710 and MR710D include both clamp and magnet mounts in the one kit, so you are covered without buying a second receiver.
Not always, but most operators find them worth it once they have used one. Without a display, you read height from the LEDs on the receiver itself, which means looking out at the machine arm or pole while you work. The wired D models bring that same reading into the cab on a 10m cabled display, so you stay focused on what is in front of you. The MR825WD goes one step further with a wireless display that mounts inside the cab with a magnet, suction cup or clamp, making it easy to move between machines without running cables. If you spend long days grading or digging to level, an in-cab display will pay for itself in speed and reduced fatigue.
These are features exclusive to the MR825WD. Blade tilt shows you whether the blade or bucket is tilted left or right. Plumb swing shows you whether the arm is swinging forward or back from vertical. Together, they give the operator a live read on bucket angle and arm position without stopping work to check manually. For excavator operators digging trenches or batters to a consistent angle, this is a significant time saver. For grading work, blade tilt helps you keep the blade flat and avoid dragging one corner. It is more information than a standard machine receiver provides, and it stays firmly in the territory of manual reading, not automated machine control.
All Redback machine receivers include a last height detected indicator. When the beam is temporarily blocked, the display holds the last known reading instead of going blank. This means the operator still has a reference point while repositioning, and the receiver re-acquires the beam as soon as line of sight is restored. The 250mm reception window on the MR7 series (260mm on the MR825WD) also helps, because a taller sensor catches the beam across a wider range of machine movement before losing signal.
Tool-brand receivers are built down to a price. Plastic internals, limited weather rating, and no real repair path when they take a hit. Redback machine receivers are built on metal chassis, rated IP66 or IP67, and designed to be repaired, recalibrated and put back to work. The internal NiMH battery charges from 240V mains or straight from the machine via the 12V/24V cable, so you are never hunting for batteries on site. Redback backs every receiver with a genuine warranty, no sign-up hoops, and offers real Australian support if something goes wrong. Free delivery Australia-wide and fast dispatch mean you are not waiting around either.
Built for Your Trade
Whether you’re running an excavator, dozer or box blade, a machine mounted laser receiver gives you instant height feedback without climbing out of the cab. Mount it to the dipper arm or grade pole and read your cut or fill depth in real time, pass after pass.
Civil work demands consistent grade across long runs where manual checking slows everything down. A machine control laser receiver keeps your operator locked onto datum without stopping the machine, cutting rework and keeping the program on schedule.
Laser grading for flood irrigation, dam construction and land levelling depends on accurate, repeatable height control across large paddocks. Clamp a machine receiver to your blade pole and your operator reads grade directly, without leaving the seat or guessing at cut depth.
When you’re setting invert levels for drainage or sewer runs, there’s no room to be out. A machine receiver paired with a rotating laser gives your excavator operator accurate depth reference on every bucket, so your pipe bed is right before the pipe goes in.
Every machine mounted laser receiver needs a compatible red beam rotating laser to work. If you need to pair one up or replace an existing unit, this is where to look.
