Excavator + backhoe guidance

Ditch Assist® DIG™ shows the operator exactly where the bucket is relative to grade.

One operator digs to grade from the seat, with cut or fill at the bucket tip on the screen. Add RTK GPS guidance to almost any excavator or backhoe and run the work in the Ditch Assist app, from quick grade and level targets to Slope-IQ™ design, mapping, file import, job recording, and resume.

What is DIG™?

Ditch Assist DIG™ is guidance built around the operator. A single operator digs and checks grade in real time from the seat. Existing machine controls and operator skill stay in charge; DIG™ adds live high, low, and on-grade feedback at the bucket. Excavator mode also runs in Ditch Assist Lite, with its GPS on the stick, but with no angle sensors it reads grade only when the stick and bucket are back in the same position each time: a check between cuts, not live grade while you dig.

See DIG™ hardware + setup →

What does DIG™ do?

The bucket becomes the grade checker.

DIG™ gives the operator the three answers that matter while digging: where the bucket is now, where grade is, and whether the work is finished enough to move on.

01
Grade on every pass.
Cut or fill at the bucket tip stays on the screen while you dig, so you watch grade and keep the bucket working.
02
High, low, or on grade.
Clear live feedback helps the operator stay on grade and stop before overdig.
03
One app from quick cuts to complex work.
Use the Ditch Assist app for simple grade targets, level work, designed trenches, mapping, saved progress, and imported files.
04
Fits the machines you already run.
Because DIG™ is guidance, it can go on almost any excavator or backhoe without needing newer machine electronics or hydraulic integration.

Step-by-step DIG™ workflows.

See DIG™ survey a route, design it with Slope-IQ™, and dig to the saved design.

Survey + Slope-IQ™

Survey and design with Slope-IQ™

Record the proposed route with the excavator, or move the rover to an ATV or UTV and survey over Bluetooth, then turn that data into a Best-Fit, Guided, or Freeform trench design. If a previous survey is loaded, the operator starts this same process at the Slope-IQ™ design screen.

What this walkthrough covers

This DIG™ walkthrough shows how an operator records a proposed excavation route, verifies RTK accuracy, saves the survey, confirms water-flow direction, sets minimum grade, and creates a Slope-IQ™ trench design.

1. Survey with the machine or rover Use the excavator itself, or move the RTK GPS receiver to a vehicle or ATV and connect to it over Bluetooth from the Ditch Assist app.
2. Verify RTK before recording Confirm the Ready to Survey screen shows connection and RTK accuracy before tapping START SURVEY and driving the proposed route.
3. Record the route Survey straight or curved routes in either direction. For wider cuts, drive the survey along the center of the planned excavation path.
4. Save and orient the survey Stop at the end of the route, save the survey with a custom name, and confirm or change the intended water-flow direction.
5. Set minimum grade Enter the minimum grade used by Slope-IQ™ to enforce drainage in Best-Fit and Guided designs. This can still be changed later inside Slope-IQ™.
6. Use Best-Fit design Let Ditch Assist follow existing ground where enough natural slope exists, then create minimum-grade cuts where the ground does not meet the target.
7. Adjust design parameters Review depth offset, minimum grade, bottom width, side slope, cut-volume estimate, and minimum/maximum depth limits.
8. Compare Guided and Freeform Use Guided to anchor the design to selected ground points, or Freeform for manual control when the operator wants to shape the profile directly.

Design guidance

Dig a saved design with Slope-IQ™

Open the saved design, calibrate the excavator to the original survey surface, and dig with the bucket shown against the designed profile. The walkthrough shows the map, profile chart, grade guide, target bar, audible on-grade cue, progress painting, autosave, and resume workflow.

What this walkthrough covers

This DIG™ walkthrough shows how an operator uses a completed Slope-IQ™ design in Excavator mode, including the map, terrain profile, grade guide, calibration to the surveyed surface, progress recording, and resume.

1. Open the excavator grading screen The map shows the machine position along the original survey route, while the profile shows existing ground and the Slope-IQ™ design grade.
2. Read the grade guide The bucket and stick graphic moves with the real machine, and the yellow target bar shows the required elevation at the current location.
3. Match the bucket to target When the digging edge touches the yellow bar, the bucket is at the design elevation for that point on the run.
4. Calibrate to the original survey Before digging, touch the bucket edge to an undisturbed surveyed area and calibrate the excavator elevation to the design surface.
5. Start guidance and dig Use the map, profile chart, and grade guide together to see where the machine is along the run and how close the bucket is to target grade.
6. Track progress and resume As work is completed, the app paints progress on the map, saves the job automatically, and lets the operator stop and continue later.

How operators use DIG™

Open Excavator mode, enter the target, and DIG™.

One Ditch Assist app covers the quick jobs — a culvert, a footing, a level pad — and the bigger jobs where design, maps, files, progress, and resume matter.

Quick work

Grade, depth, or level

Enter the target for short trenches, spot fixes, pads, footings, pond bottoms, and level cuts, then use live bucket feedback to stay on grade.

Percent grade or fixed depth Level target for pads and ponds Live bucket high, low, on-grade cues

Trench design

Straight, curved, or multi-slope

Survey the route, let Slope-IQ™ build the profile, then dig to the design with bucket position visible against grade as the work progresses.

Best-Fit, Guided, or Freeform profiles Curved drainage and utility trenches Designed target visible in the cab

Import surfaces and keep progress

Load finished-grade surfaces, work with map context, mark completed areas, and return later with the target and progress still attached.

LandXML finished-grade surfaces Completion marks + achieved grade Saved jobs with resume function

Guidance options

Pick how you set the target.

The Excavator mode menu keeps simple grade work, Slope-IQ™ design, saved jobs, and civil imports in one place, so the operator can pick the job type and get straight to bucket guidance.

Excavator mode menu

Six ways to start a job, from a quick grade to an imported LandXML surface.

Start from a new survey, open a saved survey or design, resume yesterday's job, enter a quick grade, hold a level target, or import a civil surface. The operator chooses the job type and DIG™ turns it into live bucket guidance.

Excavator using Ditch Assist DIG™ guidance

Grade in the cab

Live grade at the bucket. No 3D build-out.

DIG™ puts live bucket grade in the cab without hydraulic integration or a 3D model to build first. Enter a target and dig. When the job has a design, load a Slope-IQ™ trench or a LandXML surface and dig to it. Saved machine profiles move one kit between excavators and backhoes.

DIG™ is built for the work excavator operators do every day: culverts, footings, pads, short drains, and pond bottoms, dug from a benchmark to a target depth or grade.

DIG™ Kit

Mounts on the machine. Leaves the operator in control.

DIG™ uses IP67 stick and bucket sensors, RTK positioning, and the Ditch Assist app to show live bucket grade. It does not need hydraulic taps, valve commands, or a newer machine with factory 3D integration. Setup, calibration, and saved machine profiles are handled through the DIG™ module's built-in web interface in a browser on any device.

Machine fit

Fits most excavators and backhoes.

If the machine has a stick and bucket, DIG™ is usually a fit. Full-size excavators, mini excavators, wheeled excavators, backhoes, and long-reach excavators are common fits. Long-reach machines usually require CAN sensor cable extensions.

Multi-brand RTK

Use the RTK you own, or add an affordable GNSS package.

DIG™ works with RTK GPS from virtually any manufacturer, so you can keep the equipment you already own or choose the solution that fits your budget. Your RTK, your choice. If you do not currently have RTK, we offer cost-effective packages that are simple to set up, so you can start digging fast.

New to GPS, or already running RTK on other equipment? Tell us what you have and we will tell you what DIG™ needs.

RTK GPS options → Compare kits

01 Survey

Move the rover to an ATV or UTV.

For survey work, take the Emlid rover receiver off the excavator, mount it on an ATV or UTV, and drive the route while the Ditch Assist app records the survey over Bluetooth.

02 Design

Build the ditch or trench in Slope-IQ™.

Use the survey in the Ditch Assist app to design the grade with Slope-IQ™, including Best-Fit, Guided, or Freeform profiles for straight, curved, or multi-slope work.

03 Dig

Put the rover back on the excavator.

Return the rover to the machine, open the saved design, and dig with live bucket guidance in the app so the operator can see high, low, and on-grade as they work.

More than excavators

DIG™ guides the bucket. Ditch Assist can run the rest of the grade work.

Many operators start with DIG™ on the excavator, then add Ditch Assist for the rest of the dirt work. On a pull-type scraper, blade, ditcher, land leveler, or tile plow, the Full Automation Kit puts our valve on the implement and Ditch Assist works raise/lower. With the Guidance Only Kit you follow the arrows, work the levers, and can add our valve later; if the implement has a compatible factory valve, the kit plugs into it and Ditch Assist works raise/lower. Ditch Assist Lite puts only a GPS on the blade of any machine, from a dozer or self-propelled scraper to a tractor and scraper. It runs every mode as guidance: you work the controls, with no credit toward automation later.

Surface drainage

Ditching + Terracing

Survey a route, let Slope-IQ™ design the grade, then cut drainage ditches or terrace channels with automated or guidance-only implement control.

Fit check

Is DIG™ the right fit?

DIG™ delivers live bucket-to-grade feedback in the cab: sensors that mount on almost any excavator or backhoe, no hydraulic integration, and saved machine profiles that move one kit from machine to machine.

Best for

Excavator and backhoe operators who want live bucket-to-grade feedback — quick grade checks, designed trenches, level areas, LandXML surfaces, and multi-day jobs — without hydraulic integration or a full 3D build-out.

Different job?

Grading with an implement or a blade instead of a bucket? Pull-type scrapers, ditchers, blades, and tile plows run on the Full Automation Kit or Guidance Only Kit. With the Guidance Only Kit you work the levers and can add our valve later, or, where the implement has a compatible factory valve, Ditch Assist works raise/lower through it. Dozers and self-propelled scrapers run on Ditch Assist Lite, with only a GPS on the blade and no credit toward automation later. Start with Ditching. Already running full 3D machine control on your big iron? DIG™ puts grade at the bucket on the machines that don’t have it.

FAQ

Excavator guidance questions.

Answers for operators looking at machine profiles, sensors, RTK input, backhoe fit, and LandXML design workflows.

Machine profiles

How do machine profiles work with DIG™?

The DIG™ module stores stick and bucket sensor calibration, geometry, and offsets as a saved machine profile. Up to 10 profiles can be saved and recalled through the module's built-in web interface. Extra bracket sets are available, so each machine keeps its own brackets and one kit can move between machines without recalibrating from scratch.

Sensors

What sensors does DIG™ use?

IP67-rated stick and bucket sensors on the machine's linkage read the stick and bucket angles, and the RTK GPS on the stick gives position, so the app knows where the bucket tip is. There are no hydraulic taps or valve commands.

RTK input

What RTK GPS does DIG™ accept?

DIG™ works with RTK GPS from virtually any manufacturer as long as it provides standard position output. Your RTK, your choice — use the RTK equipment you already own, or ask about an Emlid-based bundle if you need to add RTK.

Backhoe use

Does DIG™ work on a backhoe?

Yes. Backhoes are a common DIG™ fit alongside full-size, mini, wheeled, and long-reach excavators. If the machine has a stick and bucket, DIG™ is usually a fit. Long-reach machines typically need CAN sensor cable extensions.

LandXML / design

Can DIG™ use a LandXML design file?

Yes. Import Civil Design loads a LandXML final surface and shows the design elevation live at the bucket. When before and after surfaces are available, the app can show cut/fill context, and completed areas can be marked as the work is verified.

3D bucket guidance

What kind of system is DIG™?

DIG™ is RTK bucket-to-grade guidance for excavators and backhoes, built into the Ditch Assist app. Stick and bucket sensors and RTK position track the bucket tip, and the app shows it against your target in real time — quick grade, level areas, Slope-IQ™ trench designs, and LandXML surfaces. The operator runs the hydraulics; DIG™ puts the grade in the cab.

Already have survey or design data?

Send it before you commit to DIG™.

If you already have a survey, saved design, trench profile, LandXML surface, or civil design file for the excavator work, send us the file before you buy. We can check whether Ditch Assist DIG™ can load it directly, and if not, we will look for the simplest path to make it usable.

What to send

Survey, design, or LandXML.

Send the exact file you expect to use, plus what it represents: original survey, finished surface, trench route, before/after surfaces, benchmark, coordinate system, and units if known.

What we test

Can the app turn it into guidance?

We check whether the design imports, whether the target surface or profile makes sense, whether the file is too large or missing required data, and which DIG™ workflow fits the job.

If it needs conversion

We look for a solution.

If the file does not load cleanly, we will look for a practical fix: a better export, a simplified surface, a coordinate-system correction, or a different workflow inside the Ditch Assist app.
