4. Air 8 Fitting Instructions for Grass Harrow
(6mtr model)
4.1) Seed Hopper
1. The pneumatic seed box should be fitted onto the rear support arm of the Grass Harrow approx. 750mm
from the headstock, using mounting bracket and bolts supplied. Position so that the electric fans and
seed metering mechanism is located at the back of the harrow, the seed pipes will run forward to the
distributor outlets
NOTE: 4.5m & 5m models require an additional mounting bracket (934825) to allow the seed box
to be mounted in the centre of the machine
2. The Grass Harrow rear support arm must be bolted with two M14 x 90 bolts supplied, removing the two
pins previously used. This is to prevent vibration and wear which may occur with the added weight of
seed box mounted
3. The optional operator platform should be mounted behind the seed box on the harrow rear support arm,
positioned to suit the operator
Calibration tray
support bracket
4.2) Sensor drive heel
Mount the sensor drive wheel onto the rear arking stand bottom hole with locating in
su lied. The s eed sensor wire should be routed under the latform and wired into the
electric junction box on the seeder (see wiring diagram g39.)

4.6) Hydraulic fan
The hydraulic fan is mounted at the left hand side of the harrow chassis directly behind the
l/h lower hitch oint. The air i e (ID 80mm) connects between the fan and seeder air intake
with hose cli s rovided.
The hydraulic fan requires a ressure free return oil su ly of 2-16 ltr/min, the oil flow should
be set at the tractors hyd s ool valve and must not exceed 16ltr/min—to do so may damage
the motor oil seal, when connected ensure the fan is running in the correct direction, fan
blades turning clockwise as you look at the air intake.
4. The ½“ su ly hose (marked ‘P’ on the hyd motor casing to indicate ressure) should connect
into the tractor s ool which suits hydraulic motor service.
5. The ½“ return hose (marked ‘T’ on the hyd motor casing to indicate tank) from motor should
be a ressure free return direct to the tractor hydraulic oil reservoir.
Fan speed adjustment
The fan s eed will automatically dis lay on the control box screen, the alarm to indicate the
fan is not rotating needs to be activated in the control box menu 140.0. The recommended
o erating s eed for the steel hydraulic fan: min 1600r m — max 3800r m. The normal
working s eed should be set, de ending u on working width and seed ty e. This hydraulic
fan is suitable for fine and grass seed ty es u to 12.5m working width.
Fine seeds: 2000 - 3000 r m
Grass seeds: 2500 - 3500 r m
NOTE: It is very im ortant that the seed ho er lid is air tight, ro erly sealed ensuring
air does not flow back through the ho er.

5. Working instructions - AIR 8
5.1) Basic adjustments
Before filling the ho er, lease observe the following oints:
1. Is the correct metering roller fitted?
Attention: Choosing the metering roller according to the size of the seed and the quantity to
broadcast
Seeds, where the rough-toothed metering roller is used:
Grass-seed mixtures, rye, barley, wheat, oats, etc.
(normally for large seed rates; 10kg/ha ->)
Seeds, where the fine-toothed metering roller is used:
Pure clover seeds, ra e seed, hacelia, granules etc.
(normally for small seed rates; < 15kg/ha)
2. Seed retaining brush adjustment:
The distance of the retaining brush from the metering roller can be adjusted by a lever on the
right hand side of the ho er. The brush can be adjusted from 1-7mm
The following rules must be observed:
- The distance between brush and metering roller is a rox. half the seed size
i.e. Oil seed ra e, clover 0-1mm
Grass-mixtures 1-2mm
Game cover mixtures 2-3mm
- The ga on the lower side of the roller should never be more than 1mm (Factory set)
5.2) Changing the seed metering roller
Ensure the seed ho er is com letely em ty of seed. To change the metering roller, remove the
end ca bearing holder on the right hand side of the machine. Slide out the roller, by turning anti-
clockwise and ulling at the same time

When fitting another roller, observe the follo ing:
1. Slide the re lacement roller onto the drive axle
2. Re lace the bearing holder
3. Ensure the s ring loaded discs on the ends of the metering roller take u any ga when the
bearing holder has been fitted, the discs should not be tight
4. Rotate drive wheel and check that the metering roller turns easily
5.3) Seed roller protection shield
This is mounted inside the ho er to carry the weight of seed in the ho er. It is designed mainly
for heavier seeds ie Oil seed ra e, slug ellets, etc. When working with lighter seeds ie grass seed
be careful to ensure the late does not encourage bridging in the ho er. If seed bridging is a
roblem remove the thumb screws and shield from the ho er and work without it fitted.
5.4) Sensor Drive Wheel
Release the drive wheel from trans ort osition onto the ground. Allowing for constant drive
wheel contact over undulations, in under the drive wheel arm to clear ground when harrow is
raised out of work
Drive wheel axle should have no side movement to ensure sensor ga is constant. The sensor and
drive wheel slots must be clean to rovide a good signal to the com uter. The ga from sensor to
drive wheel should be 5–8mm, this can be adjusted on the sensor mounting nuts.
5.5) Field operation
Overseeding Grass:
It is ossible to u grade existing asture by adding new seed. Harrowing old grass asture to
o en u the soil surface before broadcasting new seed is cost effective. The combination of
grass harrow and neumatic seed box will hel you get the most from your overseeding
rogramme as it im roves weed control, airs the soil and im roves conditions for grass seed
germination.
Reseeding Grass:
The benefits of increased yield and im roved forage quality from reseeding are undoubted.
Reseeding into cultivated ground is ossible with the harrow and neumatic seed box, cross
drilling in a diamond attern will ensure good ground cover, but there’s several oints worth
considering to ensure success.
1. Always check H, hos hate and otash levels rior to sowing (aim for H 6.5, P2, K2)
2. Make certain the seed bed is fine and firm

3. Roll before as well as after sowing
4. Ensure de th of seed is no more than 15mm
5. Control weeds after establishment
6. Use esticide control when sowing grass after grass
Before field ork check the follo ing:
• Check the fan is working & direction of motion is correct. Run the fan to dry any moisture
in the seed i es before starting work, this will minimise risk of seed blockage in the i es
• There should be a minimum of 20kg of seed in the ho er
• The lid of the seed ho er must close air tight
• Set the distributor outlet between 20-40 cm above ground. Harrow tine setting, cro foliage
height and seed ty e will determine the height required to ensure an even s read attern
• Check all outlets to ensure even seed coverage across the working width
5.6) Emptying the seed hopper
1. Remove the metering roller cover late.
2. Place the calibration tray into the out ut roller com artment.
3. Set the seed retaining brush at maximum height and set the control monitor to calibrate
mode until the ho er is em ty.
4. To em ty the seed ho er com letly, remove the metering roller (Ref. to 5.2)

5.7) Maintenance
Daily
1. Ensure the ho er is air tight, lid seal and metering cover late seal are in good condition
2. Check the flexible seed i e for damage or blockage
3. Check distributor lates are not damaged
4. Check the metering & agitator drive is clean and working
5. Check metering roller including s onge end ca s are clean
6. Clean the fan inlet with com ressed air, articularily when working in dusty conditions,
electric fans can collect dust on the fan vanes – if left to build u this will shorten their
working life.
Weekly
1. Check transmission drive belt, remove the two M6 nuts and cover to access the drive and
tensioner
2. Lubricate the land drive wheel
3. Lubricate the metering roller end ca bearing
4. Check all nuts and bolts are tight
5. Check air manifold between hyd fan and seeder – this has a built in erforated diffuser
late which can build u a blockage in trashy conditions and may need blowing out.
7. Check hydraulic hoses and connections for oil leaks or damage
8. Check mounting nuts and bolts are tight
5.8) Storage
1. Em ty seed ho er com letely and remove metering roller
2. Clean the unit thoroughly and aint any bare metal
3. Check for any ware or damage and re air as necessary
4. Store the numatic seed box under cover to revent any build-u of moisture in the
distributor i es, seed ho er and metering mechanism.

Electronic Control Box – Operators Guide
This Section of the Operators Manual deals with the Electronic Control Box which is fitted to Air 8 and
Variocast 8 E machines and all Variocast 16 and Air 16 machines.
The Electronic Control box allows operators to set the seeder up for the job it is doing, calibrate it and
then operate it. It provides the operator with a variety of different pieces of information about the
seeder whilst it is working and will retain these until the operator chooses to delete them.
Information such as the current seed rate being applied and current forward speed is displayed on
the screen whilst in work. The control box can also be set to keep a log of the Area covered, distance
covered, and time taken as well as monitoring the seed level and the amount of seed used.
There are also a number of warning functions that help keep the operator informed of any potential
problems.
- Low Hopper level
- No drive from the Electronic Motor
- No drive to the metering Roller
- The forward speed is too low
- The Forward Speed is too high
The instructions for using the control box that are set out below enable a new operator to maximise
the performance of his/her machine, please read through them carefully and take some time to work
through them whilst using the control box.

A2. THE DISPLAY
This displays the actual Seed rate in KG per HECTARE, when seeding. When the Seed rate has been temporarily
increased or decreased “on the move” this figure will alternate between the actual seed rate and the % it has been changed by.
This displays Forward Speed Km/H
This displays set spread width – each symbol represents a different width setting.
This indicates which field or job data read out is selected. There is the possibility to store HECTARES WORKED, METRES
TRAVELED, HOURS WORKED and QUANTITY SPREAD for 19 different fields or jobs.
Use the F4 key to toggle between Metres Worked, Hectares Worked and Hours Worked.
This displays Meters worked – without seeding.
This displays Hours Worked.
This displays Hectares Worked - seeding.
Use the F5 Key to toggle between Battery Voltage, Content of seed in the tank and Quantity of seed used.
This displays weight of seed in the tank in Kilograms.
This displays Battery Voltage.
This displays weight of seed metered out in Kilograms.
This is air fan rotational speed read out. NOT USED AS STANDARD

SECTION B
USING THE CONTROL BOX – CALIBRATION AND SETTING
B1. ENTERING DESIRED SEED RATE
To enter desired seed rate (KG/Hectare ) :
• PRESS AND HOLD F1 FOR 2 SECONDS
This screen will appear
• ALTER THE FLASHING DIGIT BY PRESSING
• MOVE TO THE NEXT DIGIT BY PRESSING
• USE THIS METHOD TO ATTAIN THE DESIRED KG/HECTARE
• STORE THE VALUE BY PRESSING (TIP: get the decimal in the right place)
• EXIT WORKING SCREEN BY PRESSING
The desired seed rate is now stored in the control box. However, on returning to the working screen the
previously entered value will not be displayed. It is only displayed when the seeder is working and a forward
speed is being achieved.
The method in which you have entered the seed rate is commonly used through out the control box. Remember:
• When a digit is flashing it can be altered
• Always stores the entered value
• Always brings you back to the working screen

B2. CALIBRATING THE SEEDER
To calibrate the seeder with the type of seed being applied:
• PRESS AND HOLD FOR 2 SECONDS
This will take you into MENU 1.0 which will look like this.
The value next to F4 is how many turns the seed roller will make during the calibration. To alter this figure press F4, the
value will start to flash and can then be altered by using the up, down and across arrows and set by pressing Ok.
When using the coarse metering roller FOR GRASS SEEDS 30 - turns is ample
When using the fine metering roller FOR SMALL SEEDS 70 – 80 TURNS IS ADVISED
The Value next to F6 is the weight of seed entered after the previous calibration.
• AT THE BACK OF THE SEEDER – SET THE BRUSH SETTING FOR THE TYPE OF SEED BEING USED (SEE
AIR8/AIR16 INSTRUCTION MANUAL), REMOVE THE METERING ROLLER COVER AND PLACE THE
CALIBRATION TRAY IN THE SEEDER
• TO BEGIN CALIBRATION PRESS .
