Tiling: survey, design and install a tile line

Tap Tiling

On the Home screen, tap the Tiling card. It's the first card in the bottom row, with a picture of a tile plow.

Not on the Home screen? Tap Home first, the black button at the top of the column down the right side.

1

Tap Connect

A window called Tiling — Connect opens. Tap the big green Connect button at the top. The app looks for the control module on its Wi-Fi.

To practise with no machine, tap Simulate, the second button. With Ditch Assist Lite the top button reads Emlid Reach. Trouble connecting: Connect.

1 2

Tap Continue

The window changes to System Check. Wait until all three rows show a green tick. The last row must read RTK Fixed, the most accurate GPS position. If it's amber and reads FLOAT, wait.

Then tap the green Continue button at the bottom.

1 2

Tap Standard Tiling

The window asks for the Tiling Method. Tap Standard Tiling, the first choice. It designs the tile from a route you drive.

Contour Tiling, below it, guides you along a contour of the field first (Contour Tiling).

1 2

Tap New Survey

The window asks What would you like to do?. Tap New Survey, the first choice, to drive the tile route now.

• Load Survey: design from a route you drove before.
• Load Design: install a tile design you saved before (Install the tile).
• Survey Whole Field: field elevations to export, not a tile route (Survey a whole field).

Set blade height, if the app asks

The first time, a window called Set Blade Height opens. Blade height is how high the plow's cutting edge sits off the ground with the plow raised in transport. The app takes it off every survey point.

Tap Auto Measure (bottom right) and follow Set blade height: the app reads the GPS with the plow up, then down. Skip for Now leaves it unset, and every survey elevation is then off by that height.

1 2

Drive to one end of the tile line

The survey screen opens with a dark card in the middle: Ready to Survey, with the reminder Drive to the start of your drain route. Drive to either end of the tile line. The outlet end is a good habit, because that's where you'll install from. After the survey, the app asks you which way the water flows.

1

Tap START SURVEY

Check the three lines on the card are green: Connected, GPS: RTK, RTK: Stable. Then tap the green START SURVEY button on the card. Recording starts straight away.

1 2

Drive the tile centreline

Drive exactly where the tile will go, at a steady pace, on RTK Fixed. A red banner at the top reads Recording Survey with the number of points so far. The route on the map and the profile along the bottom fill in as you go.

Pace, recording interval and other survey tips: Survey a route.

1

Tap STOP at the far end

At the far end of the tile line, tap the red STOP button. It's in the dark pill near the bottom of the map, next to the point count. A window called Save Survey? opens.

1

Type a name for the survey

The top of the window shows what you drove: Points, Dist and the overall Grade. The name starts as the date and time with (Tiling).

Tap the Survey Name box and type a name you'll recognise, for example North 80 main 3. The keyboard opens at the bottom of the screen (typing and hiding the keyboard).

1 2

Tap Save

Tap the green Save button in the bottom right corner of the window. The survey is saved and the design steps start.

1

Tap Yes, Correct or No, Reverse It

A window called Water Flow Direction asks you to confirm: Confirm: water flows from the START of your survey toward the END. START is where you began driving.

• You started at the top end and drove down to the outlet: tap the blue Yes, Correct.
• You started at the outlet and drove uphill: tap No, Reverse It, on the right.

1 2

Slide Target Depth

A small window called Tile Parameters opens. Put your finger on the round handle under Target Depth and slide it until the number shows the depth you'd like the tile (it starts at 36″).

The app remembers your last values for the next job, so check them every time.

1

Slide Min Grade %

Slide the handle under Min Grade % to the flattest grade the tile may run (it starts at 0.10 %). The line will never fall flatter than this toward the outlet.

1

Tap Create Design

Tap the blue Create Design button at the bottom of the window. The Tile Design screen opens with a best-fit tile line already drawn.

1

Check the design

The chart shows the ground, the tile line and the depth window: Min Depth and Max Depth, 24″ and 72″ to start with. Four cards under the chart hold your numbers. Tap a card's number, or its minus and plus, to change it.

• A red strip under the cards means part of the line breaks a limit (the warnings).
• The blue tag on the right, Required Start Depth, is how deep the plow has to be at the outlet when you start.

Everything on this screen, including Guided and Freeform, Reverse and a fixed outlet depth: Tile Design in detail.

1 2

Tap Apply Design

Tap the blue Apply Design button in the bottom right corner. A small window called Save Design opens.

1

Type a name for the design

The window says Name this design before implementing:. The name starts as Tiling with the date and time. Tap the box and type the field and line, so you can find it under Load Design later.

1

Tap Save

Tap the green Save button. The design is saved and the Grade screen opens, ready to install.

A design opened later from Load Survey or Load Design asks Calibrate GPS? at this point (once per design each app session): see the benchmark box at the top.

1

Drive to the outlet

Take the plow to the outlet: the low end of the line, where the water leaves. Tile goes in from the outlet uphill. On the map, the orange line is the tile route and the pink arrow is your machine.

1

Lower the plow to depth

Put the plow in and lower it until the box at the bottom of the depth guide reads ON GRADE. Before that it shows how much deeper to go, for example +54 and CUT: the plow is still 54″ above the tile line.

Start stays grey until the plow is within about 1″ of the design depth. A note under it says how far to lower: Lower N″ to start.

1

Tap Start

Tap the green Start button, second from the top of the right-hand column.

If a window says Start at the Outlet, you're at the wrong end: tap Cancel and drive to the outlet (Start at the Outlet).

1

Tap I Understand — Continue

The first Start of each app session shows a window called Tiling Mode — Operator Notice. It says the app has no plow pitch sensor: grade relies on RTK GPS alone. Read it, then tap the orange I Understand — Continue button in the bottom right corner.

Ditch Assist Lite skips this window: nothing moves the plow but you.

1

Pull the line uphill

You should see a red Auto Grading Active banner at the top of the depth guide. Drive uphill at your normal plowing speed. The route turns green behind you as tile goes in, and the depth readout should stay on ON GRADE.

With the Guidance Only Kit or Ditch Assist Lite, hold the plow to the guide yourself.

1 2

Tap Hold before a crossing

Before a road crossing, a service line, or anywhere you lift the plow on purpose, tap Hold. It's the grey button under the red Stop. The app stops sending depth commands; you run the plow by hand.

Ditch Assist Lite has no Hold button: tap Stop instead.

1

Tap Resume after the crossing

On Hold, the banner reads HOLD — Manual Control and the button turns orange: Resume. Put the plow back in to depth and tap Resume.

1 2

Tap Stop at the top end

At the inlet, the top end of the line, tap the red Stop button at the top of the column. The job saves itself, with any nudge and rock-hit lift. To pick it up later, open the Grade screen with nothing loaded and tap its orange Resume button (Resume a job). Tiling has no Resume Job in its start window.

If the plow rides up on a rock and the line lifts by itself: Rock Hit Detection.
