The Agri-Cruise IITM console provides a method for ground speed and engine RPM control of utility vehicles used
for agricultural purposes such as chemical application.
The Agri-Cruise IITM consists of two major modules; the console provides the automatic control based on vehicle
sensor inputs and operator interface through input switches and a LCD display and the actuator module which
provides the mechanical control of the vehicle throttle and incorporates sensor inputs for disengagement of the
control.
This manual is written for the Agri-Cruise IITM, which may be used for English, Metric or Turf measurement. Please
read the manual carefully and follow the instructions as they apply to your usage.
If you do encounter a problem that cannot be corrected by reviewing this manual, consult your dealer or distributor,
or contact a Micro-Trak technician for assistance.

Installation
Mounting the Display Console
Select a mounting location which seems most workable,
and that best fits your needs. It should be convenient to
reach and highly visible to the operator. DO NOT INSTALL IN
A POSITION THAT OBSTRUCTS THE VIEW OF THE ROAD OR
WORK AREA. Whenever possible, avoid locations that expose
the console to direct sunlight, high temperature, strong
chemicals or rain.
Place the mounting bracket in selected location, mark holes,
drill 1/4” (7mm) holes and mount bracket with bolts, lock-
washers and nuts provided. (Use self-tapping screws if not
practical to use bolts.) See Illustration 1A.

Tools Needed to Install Agri-Cruise IITM
• Screwdrivers • Pliers
• Set of Wrenches • Wire Cutter
• Electric Drill and Bits • Crimper
• 12-Volt Test Light
Actuator Installation
Mounting Actuator
NOTE: Do Not mount the Actuator Module in the following areas:
• Under the fender
• Under the vehicle
• Directly to the engine
• With the cable pointed down
• Near sharp, hot or moving objects
• Near ignition coil (No closer the 10”)
• In the passenger compartment (Noise)
• Where it will interfere with service checks.
Select a possible location to mount the Actuator Module, set
the Actuator module unmounted in that area. The reason for
leaving the Actuator Module unmounted is to make sure the
Actuator Cable will reach the throttle attaching point.
Once you have selected a location, install the Module Bracket
to the bottom of the Actuator Module with the two (2)
Module Bolts provided. It may be necessary to cut and bend
the Module Bracket to achieve a custom fit. See Illustration
to the right.
NOTE: Do Not Overtighten!. Damage to the Actuator
Module will occur if the bolts are overtightened.
Mount the Actuator Module in the spot you have selected
using two (2) of the Self-Threading Bolts provided in the kit.

Anchoring Cruise Cable
There are two (2) types of connectors used to anchor the
Cruise Cable.
• Snap-In Adapter
• Flag Nut
Snap-In Adapter
1. To use the Snap-In Adapter, it will be necessary to form
threads on the end of the Cruise Cable. This is easily
accomplished by placing the Lockwasher Nut on the
end of the Cruise Cable with your fingers. Then using
an 11mm box end wrench and turing clockwise until
the desired amount of threads have been formed. See
Illustration 2A.
2. After the threads have been formed, screw the Snap-In
Adapter onto the Cruise Cable. See Illustration 2B.
NOTE: Insulation on the Cruise Cable must extend past
the end of the Snap-In Adapter on all applications.
3. The Snap-In Adapter snaps into the square hole of
the Cable Bracket (See Illustration 2C) or snaps into an
existing square hole on the vehicle. See Illustration 2D.

Attaching Cruise Cable to Throttle
NOTE: This section will cover some of the proper ways to
use the hardware available. Each method contains sample
illustrations showing how the connector is used in an actual
installation. It must be noted, however, that you should have
an understanding of how each attachment method works so
that a proper installation is achieved.
Pulley Assembly Using the Loop Cable
1. On some vehicles it may be necessary to remove the air
cleaner to access the throttle pulley segment.
2. Set the pulley segment in an OPEN throttle position, and
remove the throttle cable from the pulley.
3. Hold the Loop Cable between the holes in each side
of the pulley. Slide the barrel at the end of the throttle
cable through the slotted hole, then through the Loop
Cable and into the second hole. See Illustration 3A.
4. Connect the Loop Cable to the Cruise Cable using the
Bead Chain Connector as follows:
Slide a Connector Cover on the Loop Cable. Install a
Bead Chain Connector onto the Loop Cable and then
onto the Cruise Cable. Bead Chain Connector may
need to be spread slightly for cable to enter. After the
Bead Chain Connector is installed, lightly crimp the
connector without pinching the cables. Then slide the
Connection Cover over the center of the Bead Chain
Connector.
5. To secure the Loop Cable to the throttle cable, punch a
small hole in the Connector Cover and slide the Tie Strap
through the hole and secure to the throttle cable. See
Illustration 3B.
NOTE: Firmly tighten the Tie Strap and remove excess to
prevent possible throttle interference.
NOTE: If the Loop Cable is not secured to the existing
throttle cable, it could come out of the pulley segment
possibly causing the throttle to be held in a partially open
position.

NOTE: After the Cruise Cable has been attached, manually
move the throttle to assure the Cruise Cable does not hang
up on any part of the vehicle.
Electrical Installation
The Agri-Cruise IITM must be connected to a 12-volt DC
electrical system. Using your test light, locate a terminal or
wire connected to your ignition switch which is “hot” when
the ignition is turned on and “dead” when the ignition is off.
Connection point MUST BE able to supply at least 3 amps.
Locate the power cable. If the selected power source is not
over-current protected, install the fuse-holder and 5 amp
fuse provided Connect the RED wire to the contact point
you have located. Attach the BLACK wire (ground) to a screw
or bolt on the equipment frame. See Illustration 2. Be sure
there is a good metal-to-metal contact. The terminal connec-
tors have been supplied for your convenience. You may wish
to substitute other types of connections. In routing cable to
console, avoid areas where the cable may be subjected to
abrasion or excessive heat.
Connect the Ring Terminal (ground) on the actuator to a
screw or bolt on the equipment frame.
Carefully route power

Magnetic Speed Sensor Installation
13
Locate the following parts:
•Speed sensor cable (Green body)
•Mounting “L” bracket
•Magnets
•Cable ties
Please Note: If you have purchased an Astro 5 GPS Speed
Sensor or a Vansco radar speed sensor, disregard the
following section on magnetic speed sensors and install the
speed sensor as described in the instructions included with
the unit.
Locations where the sensor may be installed:
1. Non-driven wheel on vehicle. This is less susceptible to
errors resulting from wheel slip.
2. Vehicle drive shaft. This type of mounting is recommended
for trucks, four-wheel drive tractors or other equipment
that has poor or no access to a non-driven wheel.
The magnets are attached to a wheel hub or drive shaft and
the speed sensor is mounted directly over the magnet. When
the wheel or drive shaft begins turning, a speed impulse
is sent to the Agri-Cruise IITM console every time a magnet
passes by the tip of the speed sensor. For the speed sensor
to operate properly, the spacing between the magnets and
the tip of the sensor must always remain constant. Before
permanently mounting any parts, be sure that the location
you have selected will meet the requirements shown in
Illustration 4.
NOTE: Observe magnet polarities (See Magnet Installation
Section).

Magnet Installation
NOTE: If using P/N 17772 Magnet Mount, ATV Wheel
Hub, please disregard this section.
Please read the following information about magnet spacing
and polarity.
The number of magnets that must be used depends on the
size of your tire and where you mount the sensor. On ATV,
tractor or implement wheels the general rule of thumb is one
magnet for each wheel bolt (minimum of two, and always an
even number). For drive shafts or small wheels, two magnets
are usually adequate.
To determine the number of magnets required, measure the
distance traveled of one revolution of the sensor equipped
wheel in inches (centimeters).
Refer to the tables to determine the minimum number of
magnets required for the measured distance.
Always use an even number of magnets, and always alternate
the polarities of the magnets as you go around the wheel
hub or drive shaft.
The magnets provided by Micro-Trak are marked with a
dashed line on the SOUTH pole side of the magnet.
See Illustration 5A.
To install, mount the first magnet with the SOUTH pole side
(dashed line) facing toward the hub or shaft. Mount the
second magnet with the NORTH pole side facing toward the
hub or shaft. See Illustration 5B.
For proper operation, the magnets must be evenly spaced
around the wheel or drive shaft. The magnets must be at
least 1” apart. See Illustration 5C.

Example: Installing four magnets with adhesive.
It is recommended that the magnets be installed on the
largest diameter portion of the axle or hub. Seethe Illustrations
on the next page to determine the appropriate method for
installation.
Clean the portion of the axle, hub or rim for the magnet
installation using a wire brush or coarse sandpaper.
NOTE: The surface must be free of oil and grease. It may be
necessary to clean the surface with alcohol.
On the section that was just cleaned, use a felt tip pen to
place 4 evenly spaced marks around the circumference and
number them consecutively 1 to 4.
NOTE: An easy method of dividing an axle into 4 equal parts is
to wrap a narrow piece of paper around the axle and mark the
place where the paper overlaps its end point and cut the paper
to that length. Then fold the paper in half, crease the paper at
the fold, fold the paper in half again and crease the paper. Un
fold the paper and wrap it around the axle and place marks
at each crease and the end point. This will give you 4 equally
spaced marks around the axle.
Perform the following steps to ensure proper magnet
installation.
1. Put a generous amount of glue at each of the marks, on
the axle, hub or rim.
2. Place the first magnet into the glue at position one, with
the dashed line facing the hub or axle and align the
magnet with the first mark.
3. Place the second magnet into the glue at position two,
with the dashed line facing out and then align the
magnet with the second mark.
4. Place the third magnet into the glue at position three,
with the dashed line facing the hub or axle and align the
magnet with the third mark.
5. Place the final magnet into the glue at position four, with
the dashed line facing out and then align the magnet
with the fourth mark.
Allow the recommended time for the glue to dry before test
driving the vehicle.

NOTE: The Speed Sensor must be attached to the vehicle
so that it will maintain its position with respect to the
magnets. If the magnets move the sensor must move with
them to avoid dislodging the magnets or damaging the
speed sensor.
Locate an existing bolt that moves in conjunction with the
magnets during suspension travel. Use this bolt to mount
the speed sensor bracket to the vehicle. See Illustrations to
the right for examples.
Form the speed sensor bracket so that the bracket will be
3/4 of an inch from the top of the magnet and one of the
holes in the brackets will be centered on the magnet, cut off
the excess portion of the bracket. This will give about 3/8
of an inch of gap between the end of the speed sensor and
the top of the magnet, when the sensor is installed into the
mounting bracket. See Illustration below.
Remove one of the Speed Sensor jam nuts and place the
speed sensor into the speed sensor bracket hole that centers
the sensor over the magnet, replace the jam nut into the
sensor. DO NOT tighten the sensor nuts.
Adjust the sensor to obtain about 3/8 of an inch between the
end of the sensor and the top of the magnet.
NOTE: Gently tighten the jam nuts to secure this position
(finger tight will usually by fine). The speed sensor is
plastic and will break if over tightened.

Speed Sensor Options
In addition to the standard Hall-effect magnetic speed
sensor, the Agri-Cruise IITM may be interfaced with a variety
of other speed sensing equipment, such as the options listed
below.
Astro 5 GPS Speed Sensor
The Astro 5 is an easy-to-install economical alternate to radar
speed sensors. The sensor converts GPS signals to a pulsed
speed signal, providing an accurate speed input even in
conditions where radar does not perform well. The Astro II is
NOT compatible with the with the Agri-Cruise IITM.
Vansco™Radar Speed Sensor
The Vansco radar speed sensor uses a microwave (radar)
signal to deliver a reliable, accurate speed signal for electronic
equipment. It features state-of-the-art electronic design/
manufacturing, rugged aluminum housing and complete
testing and certification.

Brake Sensor Mounting and Adjustment
When installed properly, the brake sensor will cancel
automatic control when the brakes are activated.
Locate the BRAKE PEDAL pivot bolt. Actuate the brake pedal
and locate a portion of the brake assembly that moves ¾of
an inch from the “at rest” position to the “applied position”
(this can be any portion of the brake pedal or its linkage).
Mark this location, the magnet for the brake sensor will be
mounted here. Clean the area next to the mark (a spot larger
than the magnet) using a wire brush or course sandpaper.
See Illustrations below.
NOTE: The surface must be free of oil and grease. It may be
necessary to clean the surface with alcohol.
Using a liberal amount of glue, attach the magnet to the
cleaned area with South facing the sensor. Locate an existing
chassis bolt near the BRAKE PEDAL MAGNET and use this
to mount the brake sensor bracket. Form the brake sensor
bracket so that it will be ¾of an inch away from the magnet
and one of the holes in the bracket will be centered on the
magnet. Cut off the unused portion of the bracket.
This will give about 3/8 of an inch gap between the end of the
BRAKE SENSOR and the MAGNET when the sensor is installed
into the mounting bracket. See Illustration to the right.
Remove one of the brake sensor jam nuts and place the
brake sensor into the brake sensor brackets hole that centers
the sensor over the magnet. Replace the jam nut onto the
sensor. DO NOT tighten the sensor nuts.
Adjust the sensor jam nuts loosely to obtain about 3/8 of an
inch gap between the end of the sensor and the top of the
magnet. With power applied to the system, press the ON/
OFF switch to enable the actuator. With the brake at rest, the
RED LED in the actuator will be off. Press the pedal and the
RED LED will turn ON. It it does not, readjust the sensor.
NOTE: Gently tighten the jam nuts to secure this position
(finger tight will usually by fine). The Brake Sensor is
plastic and will break if over tightened.

Count Enable
A low or open input on the Count Input (brown wire of the
Main Harness) selects the HOLD condition and prevents
accumulating Distance, Area and Application Time. A high
input selects the COUNT condition and allows Distance,
Area and Application Time to accumulate. See Illustration
to the right.
Connect the Count Input to a point such as a Boom Valve
which has +12 VDC when active and is open or at ground
when not active.
A SPST (single pull, single throw) switch may also be
connected between the Brown and Orange wires.

Mount magnet with SOUTH pole facing the tip of the
sensor. The magnets provided by Micro-Trak are marked
with a dashed line on the SOUTH pole side of the magnet.
See Illustration 6. Some installations may require more
than one magnet per shaft.
INSTALLATION: For proper operation, the magnets must be
evenly spaced around the shaft and at least 1” apart unless
another magnet with opposite polarity is mounted between
each of the south-faced magnets. See Illustration 7.
NOTE: magnets may be attached with a cable tie or
adhered with epoxy or other high quality adhesive.
When using adhesive, thoroughly clean the area of dirt
and oil. Use of cable ties or other mechanical attachment
is recommended, however.
The shaft sensor is mounted directly over the magnet. For
the shaft sensor to operate properly, the spacing between
the magnets and the tip of the sensor must always remain
constant. Before permanently mounting any parts, be sure
that the location you have selected will meet the mounting
requirements - See Illustration 8.
NOTE: Observe magnet polarities.

Selecting Measurement Units
English, Metric or Turf?
The Agri-Cruise IITM is capable of displaying information in
American English or standard Metric or Turf measurement
units. The Agri-Cruise IITM is shipped from the factory
programmed for English. NOTE: Changing UNITS will load
defaults, so UNITS should always be selected first and then
all other “Special” Calibrate factors may be set.
• To select the measurement UNITS you must enter and
exit “Special” Calibration. Turn power OFF and place
the rotary switch at AREA. Hold down both the CAL
and ON/OFF keys and turn power ON. Once SPEC
is displayed, release the two keys. The console will
display SPEC for 2 seconds and then the CAL icon
will turn on. The console is now in “Special” Calibra-
tion. See Illustration 8. Pressing the “+” (RES) or “-”
(SET) keys will toggle between Eng, nnEt or
TUrF. The currently selected units will be display solid.
If the units setting is changed, the non-selected units
will flash to warn the user of the potential for loading
default settings. Toggle to the desired UNITS. To load
the default settings change the Rotary Position. To save
the selected mode and settings you must exit “Special”
Calibration. Exit by pressing and holding the “CAL” key
until CAL disappears from the display (approximate-
ly 1 second).
NOTE: Changing the Measurement Units WILL load default
values. After switching measurement units, confirm that all
calibration values are correct.
