Ditch Assist X empowers you to work smarter with versatile grade control options. Using the Ditch Assist app, you can execute a simple digging operation by entering a target grade, setting a reference point with the bucket, and letting the app calculate your final grade in real time as you work. Alternatively, you can perform or import a survey of your proposed route and leverage Slope-IQ™ to design a best-fit, fully customized grading plan—including curved routes that traditional laser systems can’t handle. Ditch Assist X delivers a powerful combination of advanced functionality and intuitive ease of use that no other system can match.
✅ Ultra Rugged High Accuracy Inclination Sensors
Ditch Assist X employs two ultra-rugged, IP69K potted inclination sensors to deliver unmatched bucket elevation accuracy. One sensor is mounted on the stick near the top, while the other is installed on either the bucket or, ideally, the dogbone—since the dogbone is less prone. Through a simple calibration process, the DAX module combines the measurements from both sensors to compute a modified GPS height that reflects the actual height of the bucket teeth. This precise measurement is then passed to the Ditch Assist control module, ensuring consistent, real-time grade control at any digging position on any project.
✅ Universal GPS Compatibility
Ditch Assist was engineered to integrate with RTK GPS systems from any manufacturer, allowing you the freedom to choose or keep your existing hardware. Our custom GPS pendulum mount accomodates most agriculture and survey/construction RTK receivers, including John Deere® StarFire® receivers. If you don’t already have RTK GPS or prefer not to invest in expensive RTK unlocks and hardware, we offer the affordable and highly reliable Emlid Reach RS3. This cost-effective alternative delivers precision accuracy at a fraction of the price of traditional RTK systems—making advanced RTK GPS grade control and guidance accessible to everyone.
Ditch Assist X, or DAX as we call it, includes everything needed to add excavator guidance to an existing Ditch Assist system. To integrate DAX, you’ll need the Control Module, main harness, power harness, and GPS cable from your standard Ditch Assist Kit. DAX then adds a pair of ultra-rugged, high-precision inclination sensors, a dedicated DAX Control Module, and our proprietary GPS pendulum mounting system—ensuring unmatched bucket elevation accuracy for your excavator or backhoe.

Typical Ditch Assist X Setup
Setting up Ditch Assist X is straightforward compared to many complex systems on the market. Installation involves mounting the high-precision inclination sensors and GPS pendulum mount, then connecting the components to the Control Modules with minimal wiring. Calibration is quick and easy using our dedicated Windows calibration app, along with just a few basic tools like a measuring tape and a plumb bob.
GPS Pendulum Mount
The mount mast is typically permanently installed (welded) on the machine, positioned at the top of the stick so that the pendulum pivot point is above the boom-stick pivot.
Inclination Sensors
Inclination sensors are mounted to the upper portion of the stick and typically on the dogbone—the preferred location due to its enhanced protection. Most users choose to permanently weld our sensor mounting brackets to their machine, allowing for easy removal and replacement of the sensors without the need to repeat calibration.
Control Modules
Both the Ditch Assist™ and Ditch Assist X™ Control Modules can be conveniently mounted outside near the cab using the provided magnet mounts. A single power cable connects to the machine’s battery, one cable interfaces with the GPS receiver, and a dedicated cable connects to the two sensors.
Calibration Steps
Calibrating Ditch Assist X is essential yet straightforward when you follow the detailed instructions in our calibration app. First, install the small Windows calibration program on your PC and connect to the Ditch Assist X module via Wi-Fi. The app will guide you through several steps where you position the machine in various states and take measurements between key components. You’ll set both vertical and horizontal levels—ensuring the bucket, stick, boom linkages, and attachment points are aligned. For this process, you’ll need a step ladder to access the GPS mounted at the top of the stick when vertical, a metric tape measure, an accurate level, and a plumb bob. Calibration typically takes less than 30 minutes, and all values are saved in the Control Module, so you only need to recalibrate if you relocate the sensors or move the system to another machine. We recommend recording the measurements for easy re-entry when switching machines regularly.
