TO THE OWNER AND OPERATOR
Your Aitchison drill has been carefully designed and manufactured to give you years
of dependable service. To keep it running efficiently, read and follow the instructions
in this operator’s manual. Any questions you may have that are not covered in this
manual should be referred to your dealer:

Model: _________________ Serial Number: _________________
WARRANTY
The warranty card on your Seedmatic Professional Drill is included with this manual.
Please ensure that the registration card is correctly filled in.
The owner must ensure the dealer, upon delivery of the machine, has completed the
WARRANTY REGISTRATION CARD. This must be signed by the owner and
returned to the factory promptly. Failure to carry out this function could nullify
warranty claim opportunities against the factory in the future. Warranty claims
will only be accepted for registered products.
Indemnity from liability is a complex subject. Our indemnity makes it clear that we
are not liable for any claim lodged for breakdown, delays or machine down time, crop
failure or any other contingency involving the use of our equipment. In all these
circumstances the user can take precautionary measures to ensure that none of theses
problems occur – like having on-hand spare parts at the local dealer. Crop failures
can be caused by countless problems – our job is to mechanically place seed in the
soil and any mechanical malfunction preventing this happening can be checked during
the seeding operation and rectified by the operator.
ORDERING PARTS AND ACCESSORIES
When ordering spare parts, quote the model and serial number of the drill and use the
Aitchison part number given in the parts section. Reference to the right hand and left
hand is taken from behind in the direction of travel

SAFETY FIRST
Keep all covers in place when using the drill.
Stop the drill before making adjustments.
Lower the drill to the ground or put on props when working around the machine.
Tighten all nuts and bolts after initial use.
FOLLOW SAFETY INSTRUCTIONS
Carefully read all safety messages in this manual
and on your machine safety signs. Replace missing
or damaged safety signs, these can be ordered from
your local Aitchison dealer.
Learn how to operate the machine and how to use controls
properly. Do not let anyone operate it without instruction.
Keep your machine in proper working condition. Unauthorized
modifications to the machine may impair the function and/or safety and affect
machine life.
If you do not understand any part of this manual and need assistance, contact your
Aitchison dealer.
OPERATE YOUR MACHINE SAFELY
Be careful when operating machine to avoid injury.
Serious injury or death can result from contact with
electric lines. Use care when moving or operating
the machine near electric lines to avoid contact.
Be careful when operating on hillsides, tractor can tip sideways if it
strikes a hole, ditch or other irregularity.
Permit only one person, the operator, on tractor
platform while tractor and drill are in operation.
Keep riders off the seed drill. They are subject to injury such as
being struck by foreign object and being thrown off
the machine. They also obstruct the operators view.
WEAR PROTECTIVE GEAR
Wear close fitting clothes and safety equipment
appropriate to the job.
Wear suitable hearing protective device as
prolonged exposure to loud noise can cause
impairment or loss of hearing. Wear safety gloves
when working with discs as they can have sharp edges.
5

Operating equipment safely requires the full attention of the operator. Do not wear
radio headphones while operating machine.
BE SAFE WITH CHEMICALS
Direct exposure to agricultural and hazardous chemicals can
cause serious injury. Potentially hazardous chemicals used
with Aitchison equipment include such items as lubricants,
coolants, fertilizer, paint and adhesives. If in doubt, contact
your local Aitchison dealer for information about chemical
safety and first aid procedures. Keep a fire extinguisher and
first aid kit handy.
When disposing of chemicals, make sure hoppers are properly washed to get rid of
any chemical residue and that any chemicals are disposed of in an approved manner.
Follow instructions of chemical manufacturers for disposal methods.
USE SAFETY LIGHT AND DEVICES
Slow moving tractors and equipment can create a hazard when
driven on public roads. They are difficult to see, especially at
night. This could lead to personal injury or death if a collision
with a vehicle occurs.
Whenever driving on public roads, use flashing warning lights.
Provide extra lighting at night on machine and tractor. An
implement safety lighting kit is available from Aitchison
Industries.
TRANSPORT SAFELY
Do not exceed transport speed for machine; see your local Aitchison dealer. Never
transport at any speed which does not permit adequate control of steering and
stopping.
Reduce speed over rough ground
For safe transport, tractor must weigh more than machine.
REDUCE SPEED WHEN TOWING LOADS
Braking to stop towed loads from transport speeds can cause
the towed load to swerve and upset. Reduce speed if towed
load weighs more than the tractor and is not equipped with
brakes. Use additional caution when towing loads under
adverse surface conditions, when turning and on lines.
6

PRACTICE SAFE MAINTENANCE
Understand service procedure before doing work. Keep area clean and dry.
Never lubricate, service or adjust machine while it is moving. Keep hands, feet and
clothing from power driven parts. Disengage all power and operate controls to relieve
pressure. Lower equipment to the ground. Allow machine to cool.
Securely support any machine elements that must be raised for service work.
Keep all parts in good condition and properly installed. Fix damage immediately.
Replace worn or broken parts. Remove any buildup of grease, oil, or debris.
Remove paint before welding or heating. Avoid potentially toxic
fumes and dust when sanding, repainting or welding. Do all work
outside in a well-ventilated area. Dispose of paint and solvent properly.
Avoid heating near pressurized fluid lines or other flammable
materials. Pressurized lines can be accidentally cut when heat goes
beyond the immediate flame, which could result in severe burns to yourself and
bystanders.
Avoid high-pressure fluids. Escaping fluid under pressure can cause injury. Relieve
pressure before disconnecting hydraulic or other lines.
DISPOSE OF WASTE PROPERLY
Improper disposing of waste can threaten the environment and
ecology. Use leak-proof equipment when draining fluids. Do not use
food or beverage containers that may mislead someone into drinking
from them.
Do not pour waste onto the ground, down a drain, or into any
water source. Use the manufacturer’s directions on the correct
way to recycle or dispose of waste.
USE A SAFETY CHAIN
A safety chain will help control drawn equipment
should it accidentally separate from the drawbar.
Using the appropriate adapter parts, attach the chain
to the tractor drawbar support or other specified anchor
location. Provide only enough slack in the chain to
permit turning.
Make sure that the chains you are using has a strength rating double or greater than
the gross weight of the towed machine. Do not use the safety chain for towing.
7

GENERAL OPERATION IN THE FIELD
The drill should always be moving forward when lowered or raised from work.
Avoid stopping and never reverse with drill in work. These precautions will avoid
blocking outlets; however make periodic checks for blockages while drilling.
The speed of travel is governed by the conditions e.g. if the ground is rough the drill
may tend to bounce which would necessitate a lower speed. In optimum conditions
12 km/h may be maintained.
Always lift the drill out of the ground before turning sharp corners as this will protect
the disc openers and stop the turf from ripping.
Under no circumstances should the tractor wheels be allowed to slip excessively as
this will break the turf and the following disc may tear up the ground. If slippage is a
problem, use a tractor with more traction or wait for the ground to be in better
condition. Towing chain or bar harrows behind the drill is very beneficial as this will
crumble the groove and help to cover the seed.
PASTURELAND FARMING WITH THE AIRPRO SK2122
Continuous reaping of grasses either by machine or animal will eventually lead to
their degeneration. Desired species of grasses and legumes will weaken and their
ability to survive adverse climatic conditions will be diminished. Undesirable species
of grasses and weeds will eventually tend to dominate or pasture may simply thin out
with minimal plant populations. Of course conditions that cause pasture
degenerations vary from location to location, and from country to country, but one
can assume that every pasture can be improved no matter where its location.
MANAGEMENT CONSIDERATIONS
In describing the technique for sowing seeds into uncultivated soils, we should clarify
the terminology. It is most common to refer to CONSERVATION TILLAGE (or CT)
but it may be called SOD-SEEDING in Australia, or DIRECT DRILLING in UK or
even NO-TILL SEEDING in North America. Wherever it is practical, successful
conservation tillage requires well considered and thorough preparation, integrated
with a whole farm management program.
The cropping rotation, optimum sowing dates and grazing fertilization program will
depend on the seasonal vegetation or weed spectrum, paddock history, soil type,
fertility and drainage, and many other factors.
Here is a checklist that should be followed for any CT program (courtesy of Monsanto
NZ Ltd):
1. Check that the soil pH is around 6.0.
2. Check soil fertility levels for fertiliser requirement.
3. 3. E Establish optimum time for planting.
4. Check and control weeks present, before and during crop establishment.
5. Check and control insect and slug infestation before and during plant
establishment.
6. Check and control insect and slug infestation before and during plant
establishment.
7. Ensure soil conditions are suitable for drilling.
8. Inspect the crop regularly after planting.

Experience has shown that farmers new to CT often have crop failures on the first
occasion, but as their skills and understanding of the technique improve, so do their
crop results.
TECHNIQUES AND TIMING FOR PASTURE RENOVATION
There are two basic techniques for pasture renovation, i.e. rejuvenation and renewal.
Rejuvenation is the most efficient technique and involves sowing the seeds of new
and virile pasture grasses and legumes direct into existing pasture and have them
gradually take over the old strain, without causing loss of production due to
cultivation. This technique is known as ‘stitching in’. Renewal involves a total
herbage control system, i.e. spray off old pasture with a wide spectrum herbicide
before drilling.
Local knowledge is invaluable when determining which techniques to use and when
to use them. The best time for pasture renovation will vary by region, and is largely
governed by the temperature and weather that follow. In temperate climates with
mild winters the autumn is best; and tropical climates the spring is the best time when
the tropical grasses have not recovered from their winter dormancy. In arid climates
the time is directly before or after summer rains.
The basic requirement for seed germination is a warm moist seed bed. The aim
should be to sow the seed at a time when there is sufficient moisture for quick
germination, and little likelihood for later drought. The Aitchison opener/coulter
however will promote germination in much drier soils than any other known coulter
when used correctly.

SIMPLE RULES TO FOLLOW FOR
SUCCESSFUL PASTURE RENOVATION
10

MICRO INSECTICIDE GRANULES IN PASTURES
In New Zealand where grass grub is a problem, excellent control has been attained
with the use of Gesapon, Dasanit, Dysiston, Mocap, and Lindane in control of this
pasture destroyer. Normal rates applied on the pasture surface can be as high as 30
kg/ha but when sown in the soil and hence away from neutralizing effect sunlight,
rates as low as four and five kg/ha can be used. If unexposed to sunlight these
chemicals can remain effective in the soil as long as three months, thus killing
generations of pupae as they emerge. Also, withholding of livestock after treatment is
not necessary. Both these factors are important features with the Seedking SK2122.
Watch for slugs. Slugs like the moist groove produced by the disc opener. If slugs
become a problem (eating seeds or seedlings underground), a suitable pellet should be
used.
DIRECT SEEDING OF FEED CROPS AND ARABLE
CROPS WITH SEEDKING SK2122
We are not in a position to give total formal recommended seeding rates, chemical
usage and fertiliser recommendations because of the circumstance that the Seedking
will be used in will be so varied and diverse that some misunderstanding can occur.
Refer to the checklist and ALWAYS confirm with known successful CT operators as
well as your local seed specialist and chemical company representatives. Remember
that with this technique the environment is not as predictable as with cultivated soils,
and take the precaution of using insecticide or increased fertiliser if there should be
any element of doubt.
Seeding programs are wide and varied and it is best to look at rotation that starts with
a legume or feed crop followed by a grain crop, followed by another feed crop and so
on. Heavy pasture into grain is always disappointing, but grain after legume or
brassica is outstanding.
Here are just a few possibilities:
Brassicas, Turnips, Swedes, Legumes – Can be sown early spring (for winter feed)
or again in autumn for later winter early spring feed. The technique is to blanket
spray the entire area and ensure that seeding depths are shallow. A light bar harrow
pulled over the seeding areas is beneficial. Use fertiliser and see your chemical
company specialist with regard to the correct insecticide to use.
Winter Feed Oats – This can be seeded direct into pasture in early autumn. Herbage
control can be carried out also if necessary.
Wheat and Barley – Direct seeding in early spring or autumn depending on variety.
Spray out pasture with approved herbicide (may not be necessary after brassica).
Always sow with fertiliser.
Lucerne, Alfalfa – Sow in early spring after spraying out entire area with Roundup or
Paraquat. It is always a good idea to do a soil test to ensure that the solid pH is
satisfactory for plant establishment. Also it is necessary to ensure that the seeds are
treated with inoculants to guarantee their germination and nodulation. Use fertiliser
and ensure that spraying for insects is carried out – particularly for control of slugs
and spring snails.
Green-feed Maize – Carry out in early spring and the same rules apply as with wheat,
barley and oats. You may wish to seed in 30 or 45 cm rows and the technique for
achieving that is shown under the section SPECIAL PURPOSE SEEDING shown
later in this booklet. 11

SOWING IN CULTIVATED SOILS
As this is a tined implement with a direct drill type opener, it is important to treat all
seed beds as you would a pasture. With a conventional drill one works up the soil
into a fine seedbed so that a broad boot type coulter will pass through leaving the seed
behind the soil tilth. With the Seedking, cultivate the soil to destroy existing
vegetation but before seeding, roll the seedbed thoroughly and then drill the seeds
required into this rolled seedbed. Good germination results will occur.

12
DEPTH CONTROL SYSTEM
The Aitchison SEEDKING SK2122 seed drill is fitted with an electronic depth
control device that automatically controls the seed drill seeding depth over undulating
ground contours. This system can also be over ridden if needed by the flick of a
switch.
This system has 5 major components:
1. Depth wheel assembly. (Front centre rubber wheel)
2. Load cell. (Mounted to “Depth Wheel Assembly”)
3. Electro hydraulic valve block. (Mounted on drawbar)
4. Load cell monitor. (Mounted in tractor cab)
5. Drawbar Ram. (Hydraulic Ram on drawbar)
System overview:
When seeding the front centre “Depth Wheel” rolls along the ground, as the ground in
front of the seed drill rises or drops away so does the “Depth Wheel”.
The depth wheel is fitted with a spring and a load cell.
When the depth wheel rides up over a hump or drops down through a dip the load cell
measures the different pressures applied to the spring.
The load cell feeds this information to the “Load Cell Monitor”, the monitor then tells
the “Electro Hydraulic Valve Block” to pump oil to the top or bottom of the
“Drawbar Ram”, and this raises or lowers the front of the seed drill to match the
ground contours.
System requirements:
12 volts power supply inside tractor cab. (Cigarette lighter plug).
Continuous hydraulic oil supply, 12 l/m @ 2600psi min. (One hydraulic bank with
lever locked on).
LOAD CELL MONITOR
Manual/Auto Switch Up/Down Switch
Program Button Up/Down Button

13
SETTING THE SEEDING DEPTH
1. Ensure that the “Side Stabiliser Wheels” are folded up clear of
ground.
2. Ensure that there is power to the “Load Cell Monitor” (switch to
“Manual”)
3. Ensure that there is oil flow to the “Electro Hydraulic Valve
Block”.
4. Ensure that all other systems are connected. (Rear axle
hydraulics, Eagle Seedrate controller, etc.)
To check that the depth control system is connected
correctly:
Turn the “Up” Switch on the load cell monitor: this should drive the drawbar ram out.
Turn the “Down” Switch on the load cell monitor: this should drive the drawbar ram in.
If all of the above systems are working you can now set the
seeding depth on the seed drill.
Place seed in the hopper, drive forward slowly and raise the rear transport
wheels fully up. (Clear of ground).
Use the up and down switch on the load cell monitor to lower the front of
the drill until the disc openers start cutting into the ground. (manual/auto
switch on MANUAL)
Check depth of planted seed in seed slot, if seed is at the required depth,
good; if not use the up and down switch to achieve the required depth.
(While driving forward with the rear transport wheel clear of ground.)
Once the required seed depth is achieved read the figure shown on the
load cell monitor. Eg, 48.
This figure is what the load cell monitor needs to be set at to control the
required seeding depth.
Press the “program” button on the load cell monitor, then use the
up/down arrow buttons to select the required seed depth figure. Eg, 48
Press the “program” button to save.
The seeding depth has now been set; flick the manual/auto switch to
AUTO.
NOTE:
As the seed drill hoppers get lighter because of the product being
sown; the seeding depth may change.
If the ground conditions change (Hard/Soft) the seeding depth may
change.

14
PROBLEM SHOOTING
If the seed drill starts bouncing up and down; slow the oil flow down until
this knee-jerk reaction has stopped.
Drawbar ram moves in opposite direction than needed; swap over the
electrical plugs on the “electro hydraulic valve”.
Drawbar ram only moves slightly then stops; swap hydraulic hoses
around, (pump oil in opposite direction.
Drawbar ram does not move in or out; check there is power to the “Load
cell monitor”, check there is oil flow to the “electro hydraulic valve”,
check that the transport lock valve (tap on front hydraulic ram) is on.
NOTE:
The depth control wheel is plumbed into the Rear Transport Axle
hydraulic system.
When the drill is lowered for seeding the Rear Transport Axle must be
lifted fully clear of the ground; this will allow the front Depth Control
Wheel hydraulic ram to extend fully and allow it to follow the contours of
the ground.
The depth control wheel is also fitted with a Ball Valve; this valve MUST
be turned ON for this system to work.
DEPTH CONTROL WHEEL GROUND SPEED SENSOR
Ball Valve ON Ground Speed Magnets Ground Speed Sensor
NOTE:
The Depth Control Wheel is also used for ground speed sensing; this
speed sensing is used by the EAGLE Seed Rate Controller to control
seeding rates.
Hence this wheel has to make contact with the ground while seeding.

15
SIDE STABILISER WHEELS
The Aitchison SEEDKING is fitted with two “Stabiliser Wheels”;
these wheels are located on the front two corners of the seed drill.
These wheels are designed to stabilise the seed drill on hillsides and help
prevent the front corners of the drill ploughing too deep in undulating
ground. When these wheels are not required they can be quickly folded
up out of the way.
STABILISER WHEEL ADJUSTMENT
After you have set the seeding depth of the seed drill and the stabiliser
wheels are required, they can be lowered into place.
With the seed drill engaged (seeding) on a flat piece of ground stop
the tractor and lower the stabiliser wheels and pin into place, adjust the
wheels with the crank handle provided. (located on End Panel.)
Adjust the wheels down onto the ground so they carry some weight
(preload of about 15mm) this will ensure that the each end of the drill is
carried at the correct height.
NOTE:
Use the depth gauge decals to ensure that both stabiliser wheels are
set to the same height.
Ensure that the “R” clip is fitted through the top of the adjustment
thread to prevent the wheels self-adjusting.
Ensure that the stabiliser wheels are locked in the “UP” position
when the drill is transported on public roads.

BOOT TO DISC ADJUSTMENT
Every Dragarm has two Disc Coulters; these two Disc Coulters are
mounted on one common Pivot Arm.
Each Disc Coulter (RH & LH) has one Disc and one Boot; the Boot is
attached to the seed delivery tubes. Behind this Boot is the fertiliser
delivery tube.
The Pivot Arm can rock back and forth slightly to follow the contours of
the ground.
Dragarm; Disc Pivot Arm Assembly
Front Disc Boot Fertiliser Tube Pivot Arm Rear Disc
It is very important that the Boots are adjusted correctly against the
Disc to ensure even sowing depth and to prevent trash blockages.
The Boots should be set at lest 5mm up from the bottom edge of the
disc and have about 1mm clearance between the face of disc and the
inner face of the boot.

NOTE:
Never have a bigger gap at
the bottom than the top

17
MAKING ADJUSTMENTS
There are three bolts used to adjust the Boot; One main bolt M16 x 40
(24mm head), which is used to adjust the boot up/down and two M12 x
20 (19mm head) to adjust the boot in/out from the disc.
M12 Bolt M12 Bolt M16 Bolt
To make adjustment to the Boots raise the drill up using the
hydraulics. Ensure that the transport locks are locked.
(Rear lock on Rear Transport Axle, Valve on front Drawbar Ram.)
All three of these adjustments can be made from under the drill.
To make an in/out adjustment use the custom made 19mm spanner supplied
with the seed drill.
It is important that these two M12 bolts are tight after completing adjustments.
(Bolts should be tightened against each other).
To make a up/down adjustment loosen of the M16 bolt enough
that enable the complete Boot assembly to move.
When the boot is at the correct height retighten the bolt ensuring
that the lock washer is located in the notches provided.

18
BOOT REPLACEMENT
Over a period of time the Boots will wear down and will need
replacing.
The easiest way to go about this is to remove the complete Boot Pivot
assembly.
This can be done by pulling off the seed/fertiliser dropper hoses from
the top of the coulter tubes.(at disc coulter end).
Loosening/removing the M16 x 40 bolt that is used to adjust the height
of the boots.
M16 x 40 Bolt
The complete Boot Pivot assembly can now be slipped down from the
Dragarms.
The three countersunk (C/S) bolts have been secured by loc-tite and
may required heat to break this bond.
