3D Excavator Machine Control Solutions

Dig to Design with Confidence

See bucket position, cut and fill, depth and slope against the required surface in real time.
Reduce Rework and Grade Checks

Work closer to the target design with fewer manual measurements, corrections and unnecessary machine passes.
Increase Operator Independence

Give operators the guidance needed to complete more work directly from the excavator cab.
Make Every Machine More Productive

Maintain a more consistent workflow and use machines, crews and project time more efficiently.

01 See the Full Design in 3D

A high-refresh 3D CAD view displays the project design in clear detail, helping operators understand complex surfaces and follow the intended excavation geometry directly from the cab.
02 Configure the Cab Your Way

Customize the screen layout, shortcuts, lightbar and frequently used functions. Operators can organize the interface around their preferred workflow and access essential information with fewer steps.
03 Update Designs Directly on Site

Modify project designs in the field and view changes immediately in the 3D model. Real-time visual feedback helps operators understand how adjustments affect the planned excavation before work continues.
04 Get Fast, Responsive Guidance

The TX73 uses a high-speed data chain to keep positioning, sensor information and screen guidance synchronized. Bucket movements are reflected smoothly on the display, supporting precise operation without distracting delays.
05 Connect Machines, Files and Team

The TX73 integrates with different excavators, base stations, tiltrotators and common design files. MCSite allows teams to send designs to machines, review progress and access field data from the office.
06 Built Tough and Ready to Grow

IP69K-rated sensors and IP68 antennas support operation in rain, mud, dust, shock and vibration. TX73 Basic provides a lower initial investment and can be upgraded by registration code as project requirements become more advanced. Free over-the-air updates keep the system current without replacing hardware.

01 Improve Returns from Day One

Designed to support payback in as little as three months, the EMG100 helps reduce after-sales costs and reliance on specialist support. Reliable hardware and streamlined software keep everyday operation simple and economical.
02 Create Designs on the Machine

Create planes, slopes, trenches and holes directly from the excavator cab. Operators can prepare common excavation tasks in minutes without waiting for external design files or continuous surveyor support.
03 Install Fast and Learn Quickly

Minimal hardware and standard installation tools simplify deployment. Installation and calibration can be completed in under two hours, while the intuitive Android interface allows operators to learn the main workflow in approximately 30 minutes.
04 Work with Full GNSS Coverage

Support for all major GNSS constellations helps maintain reliable positioning across varied jobsites. The system is designed to provide consistent guidance for different machines, environments and excavation applications.
05 Fit a Wide Range of Excavators

The EMG100 supports swing booms, triple booms, tilt buckets and multiple bucket profiles. One adaptable system can serve a broad range of excavator configurations and common attachment requirements.
06 Make 3D Guidance More Accessible

The EMG100 delivers essential 3D guidance at an investment level suited to smaller contractors and owner-operators. It brings real-time depth, slope and cut-and-fill information within reach of more excavation businesses.

What Contractors Need to Know

1. What is a 3D excavator machine control system?

A 3D excavator machine control system uses GNSS positioning, machine sensors and digital design information to calculate the position of the excavator bucket. The operator sees depth, slope, cut and fill guidance on an in-cab display.
2. How does 3D machine control reduce rework?

The system continuously compares the bucket position with the required design. This helps operators avoid digging too deep, leaving excess material or repeatedly correcting completed work.
3. What is the difference between TX73 and EMG100?

The TX73 is intended for complex, engineered projects that require advanced 3D visualization, detailed design files, multiple attachment support and connected workflows. The EMG100 provides a simpler 3D guidance workflow for small and medium projects, with in-field surface creation and straightforward operation.
4. Can these systems be installed on an existing excavator?

Yes. TX73 and EMG100 are retrofit solutions designed for a range of excavator brands, sizes and configurations. Final compatibility depends on machine geometry, boom arrangement and attachments.
5. Which excavator attachments are supported?

Supported configurations can include standard buckets, tilt buckets, tiltrotators and other machine arrangements. Compatibility should be confirmed for the specific excavator and attachment combination.
6. Does the system require an RTK base station?

The system requires suitable GNSS RTK corrections. Corrections may be provided through a local base station, radio connection or supported RTK network, depending on local coverage and project requirements.
7. Which applications benefit most from 3D excavator guidance?

Typical applications include trenching, utilities, foundation excavation, road construction, site grading, slopes, embankments and general earthworks requiring controlled depth, position or elevation.
