SAFETY
GENERAL SAFETY
1. All farm machinery is potentially dangerous and should be
treated with caution and respect.
2. Never allow anyone to ride on the tractor drawbar, or on
the air seeder. The person(s) riding may fall and be
seriously or fatally injured.
3. Machinery should be operated ONLY by persons
responsible and qualified to do so.
4. Never allow anyone to climb or play on the tractor or air
seeder. They may fall and be seriously injured.
5. Follow all safety precautions in your tractor and air seeder
manuals.
6. Always exercise extreme caution in the vicinity of sharp
edges and points. Ensure guards are always fitted during
operation.
7. Footboards, footsteps and other machine surfaces may be
slippy when wet or muddy. Apply extra caution in wet
conditions and early morning when surfaces are wet.
8. Keep a first aid kit in the tractor at all times.
9. Pay attention when handling agricultural chemicals, wear
necessary protective clothing or equipment when required.
OPERATION SAFETY
1. Be sure person(s) are standing clear when starting or moving
the tractor and air seeder.
2. When air seeder is being operated or transported, be sure all
person(s) stay away from rotating shafts, gears and pulleys. If
a person's limbs or clothing is caught by the rotating parts,
serious injury or death may result.
3. When calibrating through the tablet, be sure to keep your
hands and other person's hands clear of the gears and
motors. If hands are caught in gears, serious injury can result.
4. Before starting the calibration test, make sure the air seeder
cultivator and tractor are parked in a safe and stable area,
shut off tractor hydraulic system and engage park brake to
prevent movement. If tractor and air seeder unit rolled while
you or others were under the air seeder tank, serious injury or
death might occur.
5. Never stand between the tractor and air seeder when hitching
air seeder unless all tractor controls are in neutral and the
parking brake is set. The tractor or tractor and airseeder could
roll backwards which could result in serious injury or death to
you or those nearby.
6. Operate the air seeder at a sowing speed of 8 - 12 km/hr (5 -
7.5mph).
Sowing too slow may cause overseeding at low sowing rate
(for example 2kg/hec for canola);
Sowing too fast can result in poor contour following and
uneven sowing depth.

05.19M142J3
9
9
More extreme conditions can cause greater vibration and
damage to the air seeder.
7. Apply extra care when operating the air seeder on
hillsides. The tractor or air seeder may tip over if:
It strikes a hole, ditch or other irregularity, resulting in
serious injury or death to the operator or those nearby.
Maximum GRADE OF THE ROAD (slope) should no more
than 25% (1:4).
8. DO NOT make sharp turns (over 40°) on both left turns
and right turns. Sharp turns may cause machine tilting,
may damage the ladder or Auger on the machine, and can
cause serious injury.
9. Never allow anyone to ride on air seeder while it is being
operated. The person riding may fall and be seriously or
fatally injured or may be caught by rotating shafts, belts, or
pulleys and be fatally or seriously injured.
10.To avoid personal injury or death, always stay clear of the
folding wings when they are being raised or lowered into
the field position. If the hydraulic system failed, or if the
hydraulic lever was accidentally operated, the wings could
drop, resulting in serious injury or death to you or those
nearby.
11.KEEP CLEAR. Make sure all persons are clear of the area
of air seeder before and during operation.
12.Always relieve the pressure in the hydraulic system when
air seeder and cultivator is not being operated.
13.Tank seal must not leak during seeding or fertilising
operations. Seal leaks can cause product distribution to stop
and start or cease altogether. This kind of erratic distribution
will leave unseeded strips in your field.
14.Never operate air seeder without fan motor case drain hose
hooked up. This hose must be hooked up unrestricted to
tractor hydraulic reservoir. Failure to properly install fan motor
drain hose will result in irreparable damage to the fan motor.
15.Do not use quick couplers to connect fan motor case drain
hose to tractor's hydraulic reservoir. Use 3/8" swivel adapters
only. This line must be unrestricted AT ALL TIMES. No quick
couplers can be used. If a quick coupler failed or was
disconnected during field operations, fan motor will be
irreparably damaged.
TRANSPORT SAFETY
1. Before transporting air seeder cultivator, read the transport
safety recommendations in the tractor's operator's manual.
2. Always lock the tractor‟s 3-point linkage (lower 2 points) and
air seeder hitch before transporting the air seeder. Serious
damage and injury could result from the cultivator separating
from the tractor.
3. When transporting the air seeder with the wings folded (up),
be sure there is sufficient clearance under all power lines and
other overhead obstructions lower than 3.8m. Serious injury
or death can result from contact with electrical lines when
moving or operating the and air seeder.

05.19M142J3
10
10
4. When transporting the air seeder with the wings folded
(up), be sure there is sufficient clearance of the road, the
overall transport width of the machine is 2.97m. Check
local road regulation for the allowance.
5. During the transport, DO NOT travel over 30 km/hr. Over
speed can result in losing control of the airseeder, damage
to the tyres and bearings of the airseeder and high risk of a
traffic accident.
6. Take extra care when transport with hopper fully filled.
7. Before the transport, check the necessity to open the light
kit according to local road regulation.
8. Always make sure lock the wings in the folded position with
the transport locks before transporting the air seeder. Serious
damage to the cultivator and serious injury or death could
result from the wings falling during transport.
9. Regulate your speed on hillsides and curves when
transporting the cultivator and air seeder. Loss of tractor
control could result in serious damage to the air seeder and
possible serious injury or death to you or those nearby.
10.Be sure no one is standing near air seeder when hitching air
seeder and tractor. Severe injury or death could occur if a
person(s) nearby were struck or caught by the air seeder.
MAINTENANCE SAFETY
1. Always put all tractor controls in neutral set the parking brake
and shut off the engine before servicing the air seeder. If
tractor and air seeder were to roll, you could be seriously or
fatally injured.
2. Do NOT enter tank of air seeder AT ALL TIMES. The tank is
NOT designed for people to come in; cleaning is available
through lower hopper door. You would have difficulty getting
out and may hurt yourself from falling through the top hopper
door.
3. Do not lubricate the air seeder when it is in motion. You may
fall and be seriously or fatally injured.
4. Do not loosen or disassemble hydraulic components when
there is pressure within those components. Escaping
hydraulic fluid under pressure has sufficient force to penetrate
skin. Always relieve the pressure in the hydraulic system
before making adjustments to the hydraulic system.

05.19M142J3
11
11
5. Check all hydraulic hoses periodically for signs of ruptures
and leaks. Always use wood or cardboard as a backstop,
and wear gloves and eye protection when searching the
hydraulic system for leaks. Spurting hydraulic fluid can
cause injury if it penetrates the skin or the eyes. If injured
by escaping hydraulic fluid, see a medical doctor
immediately.
6. Always permit parts, which contain hot fluid to cool to a
safe temperature before handling or disconnecting these
parts.
7. Always wear safety glasses or goggles and gloves when
working on the hydraulic system.
8. Tank must be pressurised to maintain an accurate
metering rate. Air leaks around the lid seals and the seed
cup can cause uneven distribution.
9. Be aware of worn or ruptured electric wires, a short circuit
of the electricity may cause fire and certain injury to people
who touched it.
10.When performing maintenance work on the fan, be sure
tractor engine is shut off to prevent the fan from being
accidentally operated. If the fan was accidentally operated,
serious injury or death could occur to the person(s)
performing maintenance.
ASSEMBLY SAFETY
1. Use an aligning punch to line up holes. Keep your fingers
out of these holes. Any sudden movements of heavy
components will severely injure or sever your fingers.
2. Be sure all bolts and hydraulic fittings are tight, and all cotter
pins are installed in their pins.
3. Use extra care when assembling guard-rail and hand-rail on
tank platform. The person assembling railing may fall from the
platform when no guardrail is in place.
4. Platform and ladder will be slippery if wet or muddy. Serious
injury could result if you fell from the air seeder platform or
ladder.
5. Be sure all wheel bolts are checked for tightness during initial
transport or when first air seeding. Loose wheel bolts may
result in the wheel falling off causing serious damage to the
air seeder and may cause serious injury to the operator or
persons nearby.
6. When replacing main wheels, make sure the tyre size is
400/60-15.5. The allowed load is over 2900kg per tyre. Be
aware of the correct side and the pattern of the tyre. Check
the tyre pressure before operate.
7. When replacing wing wheels, make sure the tyre size is
215/85-16. Be aware of the correct side of the tyre. Check the
tyre pressure before operate.
8. Wear gloves, heavy clothing and heavy footwear when
assembling the air package and seed boots. Points and sharp
corners of cultivator can cause injury.
9. Do not walk across the top of cultivator frame when
assembling air package. Serious injury could result if you fell.

05.19M142J3
12
12
10.Before applying pressure to the hydraulic system, be sure
all connections are tight, and the components are not
damaged.
11.Do not use quick couplers to connect fan motor case drain
hose to tractor's hydraulic reservoir. Also, do not use a
quick coupler to connect fan motor drain hose between air
seeder and cultivator. Use 3/8" swivel adaptors only. This
line must be unrestricted AT ALL TIMES. No quick
couplers can be used. If a quick coupler failed or was
disconnected during field operations, fan motor will be
irreparably damaged.

SETTING UP
Congratulations on the purchase of your new Air Drill.
This manual has been prepared to assure the proper setup,
operation and trouble-free service.
After reading this manual, keep it in the carrier provided on the
implement for quick and easy reference should any question
arise concerning operation or service.
Your AIR SEEDER is designed to give maximum service life,
but a routine lubrication and maintenance schedule must be
followed as shown on the lubrication chart (see page 20)
SETTING UP –TRAILED IMPLEMENT
IMPLEMENT LEVELLING “FRONT TO REAR”.
Adjust hitch link to level implement “front to rear” at working
position. Extend the link to increase the depth of working of
the rear tynes. Set the Disc Drill with the grain and fertiliser
box support “level” in the working position.
IMPLEMENT LEVELING “SIDE TO SIDE” / DEPTH
ADJUSTMENT
Set the adjusting screws on each side.
TURNING
Avoid turning sharply with tynes/discs in the ground. Lift the
machine out of the ground at corners and sow headlands
separately to avoid oversowing.
SOWING RATES
Select sowing rates as per the sowing chart. N.B. This chart is to
be used as a guide only.
The new AS2400lt air seeder is sowing through the electric
motor. After calibration, the sowing rate is automatically
controlled by the John Shearer App.
Check sowing rate for a reference as follows:
The sowing rate chart is based on an effective wheel rolling
perimeter of 2568mm. That is 649 revolutions of the drive wheel
correspond to 1 hectare.

05.19M142J3
14
14
SEEDING FLOW
Seed and fertilisers stored in each compartment go through
the hopper gate to the seed cup where the sowing rate is
controlled. The components from both hoppers will be mixed
in the first distributor.
The mixture is sown to the riser and distributor heads by the
air from the blower. In the default setting, both distributor
heads contain the same mixture.
For dual seeding kits, seed and fertilisers will not be mixed
and will be sent to risers separately. Each distributor head
sows different components.
TO GET AN ACCURATE CALIBRATION RESULT, A
PRERUN CALIBRATION TEST CAN HELP FILL UP THE
GAPS AND CLEAN UP ANY REMAINING SEEDS IN THE
PAST.
GATE SETTING
In the seed cup, seed and fertiliser metering rollers have
adjustable gates at the metering point under the roller. This
adjustment allows for the diversity in size of seed and types of
fertiliser. To ensure accurate metering of material, it is essential
that these gates be correctly adjusted in accordance.

05.19M142J3
15
15
PROCEDURE FOR RESETTING GATES IF REQUIRED:
1. Empty the hopper or close the hopper gate and uninstall
the seed cup from the hopper.
2. Use 8mm wrench to loosen wing nut and free the
adjustment handle.
3. Adjust the handle to a proper position according to the
„GRAIN &FERTILIZER CHART‟.
4. Hold the wing nut and use the wrench to lock the handle
tight.
„NORMAL‟ POSITION is suitable for most seed and fertilisers:
Oats, Barley, Sunflower, Rice, etc.
„COARSE‟ POSITION is suitable for large seeds and higher
rate:
Lupin, Soybean, etc.
„COARSE‟ Position is also usable when cleaning or change
products in the tank.
„FINE‟POSITION is suitable for small seeds and lower rate:
Lucerne, Canary, Canola, Millet, etc.
GEARBOX SETTINGS
The calibration is powered by the electric motor and controlled
through John Shearer App on the tablet; therefore a proper
setting is important for an accurate calibration.
The quick switch gears can be set to allow the electric motor rate
between low to high, and special sets of gears are available to
meet lower volume needs. The charts on pages 22-30 are a
guide to what rate can be expected for various products. Be
aware that this chart is a guide only, and for accuracy, a
calibration check must be done before seeding.
The drawn shows normal sitting position of how two pair of gears
fit into 16 to 27 gear ratio.
It is important to keep gears facing the right direction and
position when switching the gear ratio.

05.19M142J3
16
16
The flowing drawing shows the gear ratio 27 to 16 when
seeding big amounts.
GRAIN AND FERTILISER BOX CAPACITIES
The Grain and Fertilizer box is fitted with seed cup, which
allows either grain or fertiliser in both compartments. The two
compartments of the box are equal in volume, both 1200 litres
(966kg Wheat or 1425kg Super).
Both compartments can be closed separately and sowing at a
different rate.
The first distributor is set to mix and bisect the outcomes from
both hoppers and send to each distributor heads.
Dual seeding kit is also available, in this way, the first
distributor separates each hopper, and one compartment
comes to one distributor head.
DISTRIBUTOR ROLLERS
The default roller is suitable for both grains and fertilisers in
different sizes. After testing, it is able to provide continues
calibration flow even with small seeds and at very low rate.
DDO & COULTER UNIT SPRING TENSION
Set DDO & Coulter unit spring tensions equally on each row.
DDOs on the front two rows are more likely to need tension. To
avoid higher loads than necessary on the Tyne assembly
components, use the minimum spring tension that will achieve
the penetration required.
FERTILIZER CORROSION DAMAGE
The hopper must be “COMPLETELY AND THOROUGHLY
CLEANED OUT” after use, to help prevent corrosion. It is
especially important that the hopper is not left overnight with any
fertiliser remaining in it. Particular attention should be paid to
keeping the area around the critical distributor/bearing/gate
components free of fertiliser. It is necessary to disassemble the
seeding gate in the first distributor, as there will have remaining
fertilizer on the curved seed gate.
This recommendation is applicable irrespective of the kind of
fertiliser in use but is more important with the higher analysis,
high nitrogen, and fertilisers.

05.19M142J3
17
17
DOUBLE DISC OPENERS
DOWN PRESSURE
For best results, set the pressure only enough to ensure
adequate penetration. Packing pressure for use in the soft
ground should be much lower than for hard ground.
To adjust, turn the bolt as shown below to increase or
decrease the spring pressure as required. Increasing spring
pressure will increase the downward pressure on the
opener/press wheel.
TURNING
Lift the disc clear of the ground when turning to avoid damage.
SAFETY FIRST
DO NOT OPERATE THE IMPLEMENT WITH CHAIN DRIVE
GUARDS REMOVED.
DO NOT ATTEMPT ANY WORK ON THE IMPLEMENT WHILE
THE IMPLEMENT IS IN MOTION. (I.E. CLEANING OF BOXES
OR LUBRICATION OF DRIVES ETC.).
PRIOR TO WORKING UNDERNEATH THE IMPLEMENT (E.G.
CHANGING POINTS, ETC.) ALWAYS CHECK THAT THE
IMPLEMENT IS ADEQUATELY SUPPORTED ON BLOCKS.
