Components and Identification
The InCommand™ display will mount in the cab. Use the
provided cables in the cable kit to install power direct to the
battery terminals, routing them out of the way, and clear of
moving parts. Use the provided zip ties, to secure the
cables. If you have excess cabling, coil excess cables in an
area that will not get caught on moving parts. A RAM
mount is provided to mount the display in the cab, and
allows for flexibility to install where windows and gauges
are not obstructed.
Locate the 4001979-3 cable, and route this toward the back
of the tractor. For most front wheel assist tractors this
should reach to the plow harness that is installed on the tile
plow. If you need additional length, extension cables are
available from your dealer in 6, 12, and 24 ft lengths for 4Wheel drive tractors.

2 weather pack connectors that will connect to the Proportional valve. If you cannot route the cables to make these ends
work, extensions can be ordered by your dealer to make the connections. Route the cable as shown below to ensure that
moving parts do not pinch cables, extensions, or adapters.

Water Management Module
The module was designed to be oriented so the cable connections
face the tractor. This is so the sensors are oriented correctly and
work as they were designed. Use the provided module adapter
plate and hardware to secure the module to the plow in the location
as shown on the previous page. The label should also face up when
installing. See below image.
Make sure that you color match the connections from the harness to the module and you don’t force the connections, this
can damage electrical pins. The round connections on the harness will be used to power the GPS receiver. The 3 large and
1 small square connections will connect to the module. The Brown connector will be used for the GPS signal input.

Make sure the GPS receiver is mounted over the top of the cutting plane. There will be 2 cables that will connect the GPS
receiver to the module, one will be specific to your specific GPS receiver. The other cable connects to the WMC and has a
standard connection for all GPS adapters.
Double check to make sure that all connections are made and snug, and all cables are secured and not routed in areas that
will be pinched.
GPS Receiver Configuration
For Intellislope to receive GPS information from the receiver, the receiver needs to be sending out NMEA GGA, VTG, and
GSA messages. NMEA is a standardized output that virtually every GPS receiver supports. When connecting non-Ag Leader
receivers for use with Intellislope, the customer is responsible for knowing which port they are connecting to the WMC for
NMEA output and configuring the output of that receiver.
For all receiver types, make sure that the following messages are turned on and that the receiver has an RTK fixed position.
• Baud—19200 or 38400
• Hz—5 or 10 Hz
• NMEA messages—GGA, VTG, and GSA. Turn off all other messages.
Some Ag Leader receivers connect through different ports. See below for specific models:
• GPS 6500—Configure the above settings on Port B. Use GGA (Position). Verify StableLock and NMEA Talker are
turned off.
• ParaDyme/GeoSteer/GPS2500—Configure the above settings on Port A. ParaDyme and GeoSteer need to output
GGA current. ParaDyme and GeoSteer antenna heights must be set to 0 in the steering vehicle profile.

boxes will be grayed out and unavailable.
This setting effects the operation of Intellislope
and it is crucial that it is set correctly. When check
box is checked, it indicates that the machine
being controlled is a pitch plow and the
elevation of its cutting edge is determined by
the pitch of the plow. This must be un-checked
if the machine is not a pitch plow, such as a
parallel linkage plow or trencher, where the
elevation of the cutting edge of the machine is
directly effected by the hydraulic cylinder
displacement. In this case the GPS receiver must
move with the cutting edge for proper control.

Current calibration value to maintain grade
Setting to combat soil pressure at the start of a tile
Pitch Gain—Determines voltages necessary to effectively adjust pitch. It defaults to a value that works well for the Parker
Proportional valve and most hydraulic system flows and pressure. The gain may be increased somewhat for tractors with
lower flow and pressure. Beware of making it too large, as this will cause the plow to respond in an unstable and erratic
way. The higher the value the more aggressive response you will have.
Pitch Zero—Sensor reading that corresponds to level installation. Value will be set automatically after running Pitch
Calibration. See “Ongoing Pitch Zero Adjustment” on page 6.
Reset to Default—Resets Pitch Zero to value created by Pitch Calibration-See below section on Ongoing Pitch Zero
Suggested Calibration—Every time a Grade Control or AutoTile run is completed the system updates this number to
indicate the pitch zero during that run. If your plow tends to run low, this number will likely be higher than the pitch zero,
so increase the Pitch Zero to match this number if your On Grade indicator signifies you are running low. Conversely if it
runs high, then decrease the Pitch Zero to match this number. It is very important to watch this number to see if the
Suggested Calibration number stays close (within 10) of the Pitch Zero. If it is more than 10 off either way, you should lower
or raise the Pitch Zero to bring it to the Pitch Zero Suggested Calibration number. You can view the suggested value, and
the current Pitch Zero, during operation under the diagnostics button for the Water Management module.
PN 2006029–ENG Rev. A
If for any reason the plow was operated in Grade Control or AutoTile mode with the plow out of the ground, then the
Suggested Calibration number will be meaningless and should be ignored. Use the button beside the Suggested value
and set the Pitch Zero to the Suggested value (the pitch number will be over written with suggested).
Set as Pitch Zero—Sets the Pitch zero to the number provided by the Suggested value.
Start Compensation—At the start of an installation, the cutting edge of the plow tends to drop slightly as the shank
contacts the soil. Start Compensation allows the operator to specify an initial upward pitch to offsets this drop. The extra
pitch is reduced to zero over the first 2 meters after which it has no effect. Setting Start Compensation to zero is equivalent
to turning it off. A typical setting is 2%.
GPS-Only Gain—This gain only applies when the Pitch Zero box is un-checked. It determines how aggressively the
system reacts to elevation errors when controlling machines that are not pitch plows.
Generally these numbers will be very low like 5 or less, trial and error may be required to get the results you are desiring.
Ongoing Pitch Zero Adjustment
The Pitch Zero may need to be manually adjusted from time to time so that it remains the setting for level installation.
The following may require it to be readjusted:
• Change in soil characteristics in which the plow operates, since soft or wet soil can cause the plow to “slip” relative to
its pitch
• Substantial change in grade of the ground in which the plow operates
• Remounting of the module to the plow
• Change in ambient temperature.
The best strategy is to let the On Grade indicator guide any adjustment.

Rule of Adjustments
• If the plow is predominantly tracking below the target (too low), according to On Grade indicator, increase it.
• If the plow is predominantly tracking above the target (too high), according to On Grade indicator, decrease it.
• Otherwise leave it alone.
Intellislope ™ Tile Plow Control System
Even when the Pitch Zero is well adjusted, the on-grade indicator may reflect deviations from on grade, which is normal
and expected. The plow tends to round off sharp corners in the target profile. This will cause either high or low indications
as it does so.
There is also a certain amount of deviation within a channel about the target profile that is typical as the control system
hunts for the target and responds to external disturbances such as driving over rough terrain. The operator should remain
aware of the on-grade indicator, and if grade error starts becoming abnormally large or erratic, he should look for any of
number of pitfalls which can be giving rise to the problem.
Noise or error in the GPS elevation, noise in the pitch signal, rocks, soft spots, some degree of control system hunting and
overshoot, among other things, can cause brief deviations from on grade. Only when the plow is consistently high or low
does the Pitch Zero need adjustment.
If any of the following occur, the Suggested Calibration should be ignored:
• Operating in the “Installing” state while the plow is out of the ground.
• Operating in the “Installing” state, while any external force is being applied to the shank, including any of the
-Lifting or lowering using the three-point hitch or wheel frame
-Not placing the three-point hitch or wheel frame into float during installation
-Exerting force on the shank by manually extending or retracting a hydraulic cylinder such as the diagonal lift
cylinder on a Parallel link plow
-Operating a Soil-Max pull-type plow too shallow such that the wheel cylinder forces have too large a
component in the vertical direction.
• Operating in the “Installing” state when GPS, GPS quality or GPS RTK correction is lost.
• Installing a tile run in Pre-Ripped ground
• Operating in the “Installing” state when the three-point hitch, wheel frame, or raise/lower diagonal cylinder on a
parallel link plow is not fully in float.
If any is known to occur, the Suggested Calibration number should be ignored until after the next run.

Verify Control
Verify Control will check to make sure hydraulics
are functioning correctly and determine the
voltage necessary to move the cylinders.
NOTE! This may require that you move
over a trench to allow the plow shank to
move freely, and not overturn or interfere
with the ground.
Adjust the Up/Down Valve Thresholds, and then
go to the Verify control screen and use the
Up/Down arrows. Adjust the up/down threshold
values until moving the arrows makes the
implement start to respond.
To run the Control Verification, press button and
follow instructions on the display.
If the implement responds opposite of the
commands (for example if the UP button makes the plow go down) change the Valve Polarity setting and try again.
PN 2006029–ENG Rev. A
Up Valve Threshold, Down Valve Threshold—These two settings control how much voltage needs to be applied to
the valve to cause the cylinder to begin to move. The higher the number, the higher the voltage the system will apply to
begin moving the cylinder, and the quicker the response. The lower the value, the more slowly it will move. On the previous
screen, use the up and down buttons to see if those values improve response.
Hydraulic Pressure and Hose Hookup
It is critical to have hydraulic pressure when operating the plow. Take care that the hydraulic flow is in the correct direction.
On the front of the hydraulic valve near the hydraulic lines you will see a P and T which stand for pressure and tank. The
hose that has the pressure on it is the hose that goes into P or the pressure side of the valve. You can normally tell the
pressure side by the stiffness and vibration feeling in the hose.
The tractor's accessory oil pressure should be set high and in the detent position. Pitch plows encounter large forces which
must be overcome by the cylinders. High hydraulic oil pressure is required to generate these large forces. Setting the oil
pressure too low will cause pitch control errors.
When using a Soil-Max Gold Digger tile plow, the minimum recommended pressure setting is 2,600 pounds per square
inch and the minimum recommended flow setting is 10 gallons per minute.
If the cylinders neither retract nor extend then one of the following may be the cause:
Problem—No hydraulic pressure is available.
Solution—Tractor must be running, hydraulic detent engaged and hydraulics must be connected to Parker valve.
Solution—Hoses may be reversed or you may have a bad hose connection.
Problem—Harness is not securely connected to both module and hydraulic valve.
Solution—Check that module-side plug is completely inserted and the connector is locked.
Solution—Check that the valve solenoid connectors are fully seated and screwed down.
Hydraulics Check
This is an automated exercise that only applies to implements configured as ‘Pitch Plows’ that will extend and retract the
pitch cylinders in order to correctly set the valve polarity.
This requires that you detent your hydraulics and may require that you move over a trench to allow the plow to move
freely, and not overturn or interfere with the ground (suggested to do this away from concrete). Several items are checked
during this exercise:
• Module is connected properly
• Cables are secured to the hydraulic valves correctly
• Hydraulic flow is set high enough
• Solenoid connections are secured for operation

Look-Ahead Distance
This normally does not need to be adjusted on Gold Digger plows following the default value chart. On other plows, start
by setting the horizontal distance (in inches) from the tile boot to the shear of the plow. If performance is not optimal,
longer distance will smooth out the plow and make it less reactive. A shorter distance will make the plow react quicker but
may cause oscillatory “hunting” about the target elevation.

Antenna Offsets
Select Your Specific
Antenna to Plow Base—Distance affects the
depth because it affects how far the plow shear
is below the antenna as it is lowered.
AutoTile uses this distance to compute the tile
trench elevation from the GPS antenna's
elevation. Measure the vertical distance straight
down from the GPS antenna to the very bottom
of the plow (bottom of the skid plate).
Antenna to Tip (Horizontal)—This is the
distance from the Antenna to the tip of the plow
or cutting edge. If you had a rope hanging
straight down from the antenna, it would be the
horizontal measurement from the tip to the
rope. If the tip was 24 inches in front of the
antenna, you would enter 24 in front.
Antenna To Ground—This measurement tells
AutoTile how high the GPS antenna is above the
ground when surveying. When measuring, verify
the plow is completely lifted and plow boot is pitched all the way up.
Press “Topography” button to enter the Topography screen which allows user to setup Topography

Travel Direction
If you have RTK GPS reception, you are allowed to
collect an elevation survey. This will allow you to
collect the Latitude/Longitude and elevation
values as you traverse the field.
A point will be dropped every 10 ft as you drive
regardless of speed, or direction. If you are
collecting during operations like planting or
application using autoswath, it will also log
points outside the boundary of the field (i.e.
through a grassed waterway) to get the most
information throughout the field.
During collection of an elevation survey, points
will be logged to the file every 10 ft. An on-screen
visual will appear in the form of a single black dot
(A) every 100 ft.
ATTENTION!: It is critical that the GPS
Antenna to ground measurement is
correct in your configuration, any error in this measurement, will add to the error in the data logged.
The following are suggestions to get the best possible elevation survey for a given field. Following these recommendations
will provide the best results for your field.
• Keep swaths in the field to 62 ft or less, the closer the better.
• Driving a dedicated route at the lowest or highest points in a field (i.e. lengthwise of a grassed waterway, or at the top
of a ridge) then traversing the field in regular swaths will provide the best detail of the field.
• If surveying with the tile plow antenna, ensure that the plow is in the fully raised position.
• Driving too fast with mounted plows, can cause bouncing and affect quality.
• Surveying with harvesting equipment can provide streaked maps as the hopper filling and unloading can affect the
height of the vehicle, and therefore antenna.
After the survey points have been collected, they
will be converted into a surface layer in which
you can define the color scheme Red, White,
Blue, or Brown-Tan.
You can select the number of legend ranges for
your field that will show the areas desired. This
theme will be used for each field until changed.
Hues will represent:
Red, white, blue scheme
Darker blue = Lower elevation.
Darker red = Higher elevations.
White will be a transition color between.

Dark brown = Lower elevations.
Tan = Higher elevations.
If at any point during collection your GPS correction status changes out of RTK fixed, logging will be suspended.
If you re-acquire the RTK signal, logging will automatically resume.

If you forget to stop logging as you leave the field, you will be prompted with the message that data collection is still active,
and be given the option to continue logging, or end operation.
In Odd-shaped fields, the surface rendering of the elevation will connect areas even if you haven’t driven through
that area.
About Surveying
AutoTile can make tiling much easier by creating a sophisticated target profile that hugs the topography of the ground at
a selected depth. AutoTile requires that a survey is taken, which records the soil elevation profile, before installing tile. The
profile is created by driving over the path where the tile will be installed with the Intellislope system in Surveying Mode.
The profile is used to create the target profile for tile installation.
Surveying With a Vehicle (Not With Plow)
Surveys may be conducted prior to installation. This allows the flexibility of performing surveys with other vehicles such as
ATVs, trucks or utility tractors. The survey log can be saved on a USB drive and transfered to a different vehicle or display for
installation. Ensure that the GPS antenna is securely mounted, and that the Antenna Distance To Ground entered in the
Machine Setup screen is correct. Survey logs record the elevation of the ground based on this setting. The log will reflect
the setting at the time the survey was made. Any change to the Antenna Distance To Ground setting will not take effect
until the next survey is performed.
It is also strongly recommended that if doing a survey days prior to installation that the GPS Base station is not moved, or
is reset in exactly the same location as when the survey was collected. Failure to have the base in the same location can
render the surveys inaccurate, requiring them to be redone.

WARNING! Hydraulic machinery can cause bodily injury or death!
The Intellislope control system is designed and tested with safety of operation in mind, however, the operators should
never assume that they can anticipate the behavior of the system while it is powered. Follow these rules:
Stay away from the controlled machinery. Always ensure that no person is within the range of motion of the controlled
machinery while the control system is powered.
If it should be necessary to work in proximity to the machinery, first power off the control system. The system may be
powered off using the display or by removing the system harness.
When controlling machinery other than a Gold Digger plow, the operator must exercise good judgment to ensure that the
range of motion of controlled machinery is clear while the system is powered.
Turning off the display, or cutting the power by removing the accessory power plug, will remove power from the hydraulic
valve solenoids. This will cause the Parker proportional valve, which is standard on the Gold Digger tile plows, to close.
Other components of the machinery, such as hydraulic system elements, have their own safety rules which are outside the
scope of this manual, but which you should familiarize yourself with and follow.

0.1% grade is a common minimum grade. Min
Grade affects the target profile that the control
system “aims” at. It is normal for some deviation
about the target within a channel about the
target profile.
Minimum Depth—This specifies the
shallowest depth at which you want AutoTile to
place tile, at any point in the tile run. Keep in
mind that this depth is to the bottom of the
trench. You might want to change this distance
if you change to a pipe with a larger or smaller

Maximum Depth—This is used by AutoTile to know how deep the plow can go. You can either use the maximum depth
of the plow or use this to limit the depth you wish the plow to run to lower the pull required if ground conditions are
Target Depth—This is the depth at which AutoTile aims to install the tile (as long as other constraints permit). This is
usually in the 30-42 inch range. You should adjust this if necessary to keep your tile above impermeable clays. This depth

Intellislope ™ Tile Plow Control System
Start Depth Message
The plow may be lowered to any depth at or
below the minimum starting depth, when
installing from the outlet end, or uphill, as in
most cases. Here the plow is still above the
starting depth and a warning message,
“Minimum starting depth: 23 in.” is given.
If your starting point for the install is in a location
that is in front of your survey, the “Start Depth
message” may be too shallow as it is reported
based on the first point of the survey. For
example - if the start depth is 34" but you are 30
ft away from the beginning of the survey, you
may have to lower to 35" to maintain your grade
from the start of install to the start of the survey.
You must be within 65 ft (20 m) of the start of the
survey to be allowed to start installation.
Start Install button will be grayed out until plow
has been lower to proper depth.
Auto Level—Automatically levels the cutting
edge of the plow as it is lowered to its starting
position (pitch plow).
If the machine is not configured as a pitch plow,
the “Up” and “Down” buttons are used to
manually adjust the position of the machine's
cutting edge.
Note that the plow depth indicated on the
screen is relative to the elevation of the nearest
surveyed point, which is not necessarily the
same as the depth in the hole, since the
surveyed path may have ended some distance
from the starting hole.
WARNING! When the plow has been set
into the hole, press the “Start Install”
button to be ready to start installing.
When pushing AutoLevel make sure people are
clear, as the machine will move.

AutoTile in Process
As installation progresses, the progress is marked
by a shaded region under the target profile.
If the plow starts substantially below the target
depth, the target profile will initially rise at an
aggressive pitch to reach its target depth, and
then level out.
The overhead map continuously updates to
show your current location in relation to the
On-grade Indication—Intellislope displays how close the current installation point is to the target
This is similar to the arrows and on-grade signals displayed on laser masts. The distance off the target
profile is indicated in inches shown as high or low. Otherwise “0.0”” is displayed on a background of green.
If this indication shows the plow running consistently too deep, or consistently too shallow, (and it is set
up as a pitch plow) then the Pitch Zero needs to be adjusted on the Machine Setup screen. Please see the
section “Ongoing Pitch Zero Adjustment” for detailed instructions. If you are using a non pitch plow, GPS
Gain can be adjusted.
When reaching the end of the survey path, press
the “Stop Install” button to finish the run and
save the installation log.
To extract the plow, press the “Up”
button to manually nose the plow up while pulling ahead to bring the plow out of the ground.
Never try to pick up the plow using the three-point hitch, or the wheel lift frame for a pull type, when it is in the
ground. Always pitch the plow up and pull forward. When the cutting edge is close to the surface, use the wheel
frame or three-point hitch to raise to transport position.

Grade Control
If you have tiled with a laser, Grade Control should be natural. You select grade and grade break the same as with a laser.
Grade Control is very similar in operation. The key advantage is that all adjustments are made in the cab instead of at the
transmitter and mast.
Running Grade Control
Press the

Auto Level—Automatically levels the cutting
edge of the plow as it is lowered to its starting
position (pitch plow).
Start Install button—Once the cutting edge
of the machine has been lowered to its starting
position, pressing this button will cause

to accept Target Grade.
Once grade is accepted, the machine will
automatically adjust as it is driven forward.
Target—Use this button to select the grade you
desire. You can change this setting on the fly, and
Intellislope will follow the new grade starting at
the point when the Target grade changed.
Use the + and - button to reach the desired
value, or press the target button to enter the
desired value on a keypad.
If you are installing uphill, you will need to set the
target grade to a positive number, if you are
driving downhill, use a negative value.
(The laser equivalent to changing this setting
would be: stop the tractor, relocate the laser to
the new location, adjust it to the new grade, and
resume installing.)
Grade Break—This gives you the ability to add
a vertical offset to the tile profile which makes
the plow run shallower. Use this if you are too
deep. The current Target Grade is otherwise
maintained. An example of a common use for this is if you had a flat run at 0.1% grade, went up a hill, and then flattened
out again. You could leave the grade at 0.1% and then grade break up the hill until you get to where it flattens out.
Intellislope ™ Tile Plow Control System
On-grade Indication—Below the Target

Pitch Zero needs to be adjusted on the Machine
Setup screen. Please see the section “Ongoing

If you are setup as a Non pitch plow, and you are
running too high, you need to adjust the GPS
gain as a lower value, if you are running too low,
you need to adjust to a higher value.
Noise or error in the GPS elevation, noise in the pitch signal, rocks, soft spots, some degree of control system hunting and
overshoot, among other things, can cause brief deviations from on grade. Only when the plow is consistently high or low
does the Pitch Zero need adjustment.

Pitch Control
Pitch Control mode is only applicable for pitch plows. Other types of machinery should not attempt to use this mode.
Pitch Control is a fall-back mode of operation which may be used when GPS is unavailable. Keep in mind that:
• The Pitch Zero must be calibrated and correctly adjusted.
• Always prefer Grade Control or AutoTile mode when GPS is available. Pitch Control mode does not use GPS. It merely
holds the plow shank at a specified pitch based off the WMC.
• Do not depend on the installed grade matching the pitch with better than 0.5% accuracy.
• Entering the incorrect pitch with a pull type plow may result in the plow emerging from the ground, and be unsteady,
possibly resulting in the plow tipping on its side.
• Always use visual depth and pitch to verify plow operation.

During your field operation, the GPS (satellite)
button in the upper right-hand side of the Status
Bar should appear as green, which means you
are receiving a differential GPS signal. If this icon
appears yellow, you are still receiving GPS but are
not receiving a differential signal; and if it
appears gray then you have lost GPS. In either
case, you should check your GPS settings.
The two buttons on the top left will appear if the
display is receiving GPS signals from two GPS
receivers (one from plow-CAN, one from vehicle
-serial, or Ethernet).
Lessons Learned and Pitfalls to Avoid
The following is a list of pitfalls that we've observed and can degrade performance. Operators should be aware of these to
better avoid them, and should be alert to the on-grade indicator and installation profile to detect when these conditions
arise. Some are under the control of the operator while others are not, such as hitting rocks and loss of GPS fix or quality.
The list is provided on a best effort basis; it may not be exhaustive. Should an installation error occur, it is straightforward
to correct by installing a bypass around the affected section of tile.
Extreme Soil Conditions—Hard clay soil, loose already-plowed soil or soft bottoms can interfere with the ability of the
shank's trajectory through the ground to be controlled by the shank's pitch. Normal operation requires that the pitch of
the shank guide the trajectory. Soil that has been overplowed and is loose does not generate sufficient force acting on the
shank surfaces to allow pitch to control the elevation.
Intellislope ™ Tile Plow Control System
Tractor Effects—A tractor effect is an interaction between the tractor and plow that can push the plow off the target.
One such effect occurs as the wheels of the tractor pass over a sharp hump, trash from previous plowing or any uneven
surface, the plow hitch will be similarly raised or lowered, pulling the plow frame with it. Pitch control will compensate,
however the hydraulics can only fill the cylinders so fast, and so they may not keep up. To allow the system to keep up,
drive over any uneven surface as slowly as possible.
Low Hydraulic Pressure—Forces acting on the buried plow shank are large. In the face of these forces, the hydraulic
cylinders actuating the plow shank must create large forces and thus high hydraulic pressure is required to displace them.
Insufficient hydraulic pressure can leave the system unable to adequately control pitch. Lower pressure can also make the
plow slower to respond as it slows down the rate at which the hydraulic cylinders fill.
Older tractors may have open-center hydraulic systems in which hydraulic pressure is proportional to engine RPM, so at
low RPM there is insufficient pressure. Modern closed-center hydraulic systems are pressure regulated and are not subject
to this problem.
Failure to Float the Three-point Hitch or Wheel Frame—The plow needs to float and freely pivot as it goes through
the soil. Force exerted from the three-point hitch, or wheel frame on pull type plows will displace the plow from the target
depth. Always ensure the three-point hitch, and wheel frame are in the "Float" setting before beginning installation.
Operating Too Shallow—(less than ~20 inches), and Pull-type Plow Down Pressure
Forces bearing upon the top of the shank allow it to drive deeper when required by control logic. When too shallow, this
force can be insufficient.
Related to this issue is the down pressure in the wheel cylinders of a pull-type plow. When shallow operation of a pull-type
plow is required, the valve setting on the down-pressure cylinders should be lowered. Too much up pressure can also lift
the plow up from the target profile.
The down pressure, depth of operation and soil conditions may interact such that some soil may require deeper operation
or lower down pressure than other soils.
Driving Too Fast—When an installation is started with the plow much deeper than the target profile, the system will
schedule a target that rises rapidly towards the target profile. When this steep section meets the relatively-level target
profile, driving too fast can cause the plow to overshoot the target, as the cylinders can only change the plow pitch so fast.
Drive slowly when the target profile grade is changing rapidly.
Obstructions—If you encounter a rock or other obstruction in the field use the Stop Tiling button, and end the install.
After you have freed the plow from the rock you are now able to continue tiling. If using Grade Control Mode, you can use
the Grade Break to raise the target depth to prevent a flow reversal in the tile. If you were using Autotile, re-select the
survey, and adjust the depth settings to create a new target depth. This may include lowering the Minimum depth value,
lowering the grade, or lowering the max depth value.
Detuned Configuration Parameters—The pitch gain, look ahead distance, valve thresholds, start compensation and
pitch zero settings are discussed in “Water Management” on page 10. Low gains and valve offsets can make the plow
respond too lazily, and setting them too high can induce instability.
GPS Interruptions—The elevation control is only as good as the ability of GPS to report elevation. Loss of GPS fix or
quality, or change in satellite constellation can cause the GPS to report erroneous elevations. If using a battery-powered
RTK base station, the battery can run down leaving the unit without correction.
Defective Components—A rusty/dirty hydraulic valve is an example of a bad component that can degrade
performance. Of course as with any electro-mechanical system. Ensure that when connecting hydraulic lines to the tractor,
that the tips are clean before connecting them. Intellislope components are not immune to failure. Most component
failures lead to the system being inoperative, not degraded performance.
