15 Machine components
Feed Motor
The feed motor can be turned ON or OFF, either manually via the head unit, or automatically by the
remote mounted spring finger switch which can be fitted to the linkage or the implement. The feed motor
must be switched ON via the head unit for the spring finger switch to work automatically.
Spring Finger Switch
The switch should be mounted to a suitable place on the implement or linkage of the tractor, thus
deflecting the spring, and automatically switching the feed motor off or on accordingly as the circuit is
made or broken.
Position the finger switch so that the tip of the spring comes into contact with the moving part of the
implement or linkage when lifted out of work, and remains deflected until the implement is lowered back
into work. NOTE. Ensure that there is sufficient and positive deflection on the spring to prevent accidental
switching ON or OFF if the implement moves slightly up or down in work.
The standard wiring as supplied for this switch is when the spring is at rest, the feed motor will run
normally. If required, the switch can work in the opposite mode by changing the position of the 2
wires inside the switch
so that the switch is out of work when the sprung is at rest.
To change over remove the PVC cover plate held in position with the retaining screw to access the wiring
terminals. Remove the 2 wires from terminals 13 and 14 and re-connect to terminals 21 and 22
(nearest the gland nut) then re-fit the PVC cover plate. (NOTE the area meter also stops when the feed
motor stops)
12v Disc Motor
The disc motor can be switched on and off and the disc speed adjusted on the instrument panel
GPS Sensor
Small and compact with integrated magnetic base for ease of fitting to tractor cab or suitable mounting
position. Fitted with a 5m lead which plugs into the i-Con instrument connector cable
Hoper Level Sensor
The instrument will alarm once the product in the hopper falls below the level of the sensor
Main Power Cable
The power cable should connect directly to the vehicle battery posts to ensure adequate 12v supply to
the disc motor. The in-line is 25 amp.
This 7m power cable connects from the battery to the power input flylead on the machine. .
Instrument Lead
The 6m instrument lead connects to the junction box mounted on the machine, and runs to the i-Con
instrument panel connector lead in the tractor cab.
NOTE Extension power and instrument cables are available if required.

17
17-2 Spread width and pattern
BASIC RULE. The spread width is dependent upon the density of the granule or seed, and the disc speed
(plus other factors).
Large, dense granules and seeds with a high disc speed give the maximum spread width – small, light
granules and seeds will not spread as far.
Other factors affect the spread width:
Type of slug pellet. Typically, a large, dense hard pellet should spread further than a small, light, soft pellet,
because it is comparatively heavy and does not powder on the disc. Typically, a ‘wet’ produced pellet will be
hardest, a steam produced pellet mid range, and a dry produced pellet the softest. However, the line
between traditional ‘mini’ pellets and ‘full size’ is blurred – most are of similar size and some lower priced dry
produced pellets termed, as ‘minis’ are actually larger and heavier than more expensive wet produced pellets,
and can have a good spreading characteristics.
Seed varieties and dressings. Different varieties and dressings will affect the density and the spread.
Wind Conditions. Dead calm conditions are the optimum; any wind will affect the width pattern.
High forward speed. The same as driving into a headwind of the same speed on a calm day, and this will
peel the edges of the spread pattern backwards and inwards.
Disc speed. Altering the disc speed will affect the width and pattern. A higher disc speed will give a wider
spread width.
Disc condition Ensure in good condition and not worn excessively. Replace if necessary.
Low disc height. Will not allow the product to reach its maximum width before gravity takes over.
Low electrical power. Will not allow the disc to reach full speed.
High application rates. Loads the disc more than a lighter rate and can slow it down.
Incorrect disc angle. It must be at least horizontal – not angled downwards.
It is the responsibility of the operator to ensure that no other persons enter the spreading zone
whilst the machine is in operation.
17-1 Setting the headland deflectors
Adjustable deflectors that reduce the exit aperture from the disc are incorporated
into the Fan Jet to physically limit the spread width for headland control.
Undo the black plastic knob at the rear of the chassis and slide each deflector
around the disc as far as required to prevent chemical granules from entering a
watercourse of grass margin.
Re-tighten the locking knob.
NOTE Use the motor disc speed in conjunction with the deflectors, and the bias
adjustment.

18
18-1 Setting the feed rate
The feed rate is adjusted by the feed motor speed and by fitting different feed roller combinations.
Each combination giving different feed rates of material per revolution. Refer to the Calibration Procedure and
with the appropriate feed rollers fitted, follow the instructions. You may have to change the feed rollers to
obtain the application rate within a sensible forward speed range which is calculated during the calibration
procedure.
When re-fitting the end plates to the feed block after changing the configuration, the end plate should be able
to fit flush with the feed block by hand, without having to pull it home with the socket head screws.
The assembled rollers and spacers should not be under compression.
NOTE. You should be able to rotate the feed shaft with your fingers – if it feels excessively tight, check the
feed roller and spacer composition or call Stocks AG for advice.
WARNING Always observe all application standards and guidelines provided by the
product manufacturer as some products may be toxic !
If unsure contact your supplier for more information.
NOTE always ensure a stainless
disc is fitted to each side of the set
of 1,2,3,4 or 5 feed rollers used in
each half of the feed block.
They are important and needed to
reduce friction between the feed
rollers and the plastic spacers.
Photo of a feed block assembly with 6
feed rollers and 6 blacking spacers fitted
18-2 Feed roller configuration
For higher outputs or applying large seeds or granules the
machine is also supplied with 2 larger 8 section feed rollers
and spacers to allow 1 or 2 to be fitted as required.
The feed rollers are easily changed by removing the feed
block as follows.
NOTE Empty the hopper completely before removing
the feed block.

larger 8 section feed rollers fitted
1. Undo and remove the 2 black
plastic knobs holding the feed block
in place
2. Slide the complete mechanism out
3. Undo and remove the 4 socket
head screws on the end of the
housing opposite the retaining plate
and remove the end plate
4. Slide the rollers and spacers off
the shaft, and replace with the
alternative rollers and spacers in the
required combination
5. Refit the end plates and re-fit the
feed block and black plastic knobs.
The machine is fitted 10 white 5mm polyurethane 18 tooth feed
rollers as standard these have a stainless steel drive disc embed-
ded. Depending on the combination of required seeding rate,
implement width and forward speed 2 to 10 feed rollers can be
fitted with maximum rates achieved by fitting all 10 feed rollers.
The black 5mm wide spacers supplied are the same width as the
white feed rollers and used to replace feed rollers as required

the feed block with the hopper uppermost, ensure the drive
shaft aligns and secure with the supplied screw knobs.
4. Secure with the two small blacks PVC knobs supplied.
3. Insert the (removed) feed block into the Calibration
Hopper, ensure the drive shaft aligns by slowly rotating the
feed shaft
5. Place a suitable container under the Calibration Hopper to collect pellets whilst calibrating

20 i-CON Calibration (Page 1 of 2)
You will need a suitable container to collect the product or seed when calibrating, and an accurate set of
scales which weighs in grams
At the machine
1. Fit the calibration hopper and feed block assembly (see page 19)
2. Position a suitable collection tray directly underneath the calibration hopper to catch the product
3. Place a few kilograms of seed in the hopper
At the ICON instrument
1. Switch the spinning disc off at the instrument (see page 16)
2. Switch the head unit ON via the left hand side push
button – wait until the start-up routine has finished
and displays the main “home screen”
3. Scroll through to the Setup Menu and select the
Applicator Icon
4. Adjust the implement width accordingly - refer to the
RDS manual, page 25, section 3.3, Set Implement
Width
5. Ensure the correct application rate is
entered – select and adjust accordingly,
refer to the RDS manual, page 21, section 3.1, Setting the Application Rate
6. Ensure the feed roller setup is appropriate for the intended product or seed type, application rate and
forward speed range for application
7. The instrument calculates the calibration factor from the working width, target application rate, and the
metered weight delivered whilst calibrating. If however as a result of the calibration routine, you find that
you cannot achieve your desired field speed, displayed in the top right corner of the screen, then
re-configure the feed roll assembly and repeat the calibration procedure
8. Prime the feed rollers with product by pressing and holding briefly the prime button on the junction box
- this will ensure a higher initial calibration accuracy, empty the contents of the tray back into the hopper
9. For an Auto Calibration from the Product Setup page, touch
10. Touch and enter the quantity that you wish to dispense for calibration purposes. You can enter
the quantity in grams if preferred. The CAL factor will however, still be calculated in kg/rev
11. Touch on the screen page
12. After the key the motor runs at the calibration speed (calculated from the Simulated Forward
Speed, Width, Application Rate and current calibration factor)
13. The dispensed weight (based on the current calibration factor) is displayed
14. Weigh the product dispensed and then enter the measured weight, and press
15. A new calibration factor is then re-calculated and displayed
16. Your in field min and max speeds will be displayed as per the image to the right hand side. If you find
that you cannot achieve your desired field speed, then re-configure
the feed roller assembly and repeat the calibration procedure
(see page 18 for more details)
17. Touch to save the new factor, it is advised to repeat the
calibration 2 more times to ensure accuracy
