CONSERVATION AGRICULTURE
According to the FAO (Food and Agriculture Organization of the United Nations), “Conservation
Agriculture” (CA) aims to achieve sustainable and profitable agriculture and subsequently aims at
improved livelihoods of farmers through the application of the three CA principles: Minimal soil
disturbance, permanent soil cover and crop rotations.
CA holds tremendous potential for all sizes of farms and agro-ecological systems, but its adoption
is perhaps most urgently required by smallholder farmers, especially those facing acute labour
shortages. It is a way to combine profitable agricultural production with environmental concerns
and sustainability and it has been proven to work in a variety of agro-ecological zones and farming
systems. It is been perceived by practitioners as a valid tool for Sustainable Land Management
(SLM).”
Head to the Food and Agriculture Organisation website for more information:
http://www.fao.org/ag/ca/index.html
NO-TILL SYSTEMS
“No-Tillage” is a ‘cornerstone’ of CA and can be practiced in both large and small farming
systems. With No-Till (also termed zero tillage and direct drilling) the only tillage operations are
low disturbance seeding techniques for the application of seeds and fertilisers directly into the
stubble of the previous crop. Gradually, organic matter of the surface layers of zero tilled land
increases, due to reduced erosion, increasing yields and resulting in more crop residue added to
the soil surface.
Gradually, organic mulch is developed on the soil surface, and this is eventually converted to
stable soil organic matter because of reduced biological oxidation compared to conventionally
tilled soils. No-Tillage is effective in mitigating many of the negative on-farm and off-site effects of
tillage, principally humidity loss, organic matter loss, reduced biodiversity and reduced runoff.
These conditions are replaced with permanent soil cover, improvements in soil structure,
improved organic matter status, improved water use efficiency and improved soil biology and
nutrient cycling.

BEFORE YOU START
Check List
1. Read and understand operator’s manual on how to operate correctly.
2. Check tyre pressure and inflate to required pressure minimum (40 PSI). Refer to page 26
3. Lubricate frame and units with recommended grease at stated service intervals. Refer to
Page 20
4. Inspect for loose, damaged or missing parts. Repair or replace before use.
5. Make sure air and hydraulic hoses do not interfere with moving parts. If there is
interference, relocate hoses and secure in position.
Tighten Wheel Nuts & Wheel Bearings
Tighten all wheel nuts after first 4 hours and wheel bearings during the first week of operation and
check periodically after that. Refer to page 25. This is a part of general servicing.
To adjust wheel bearings:
1. Jack up machine.
2. Remove centre hub cap and split pin.
3. Tighten nut until there is a slight drag on the bearings, while turning wheel.
4. Back nut off until split pin can be placed in hole.
5. Replace hub cap.
6. Torque wheel nuts to 255ftlb as per recommendation page. Refer to page 25.
Guidelines for Use
1. Ensure units are fully raised before lowering or raising the wings.
2. Clear wing area of people and obstacles and ensure locking pins are removed before
lowering or raising the wings.
3. Raise units fully out of the ground before making sharp turns, such as at row ends or
turnarounds or when backing up the machine.
4. Have machine moving forward before lowering units, to avoid blockages.
5. When units are in working position, operate at a maximum ground speed of up to 12 km/h.
If conditions are rough or unfavourable you will need to reduce your ground speed to suit.
6. Travelling speed with units raised and wings folded is a maximum of 30km/h. It is desirable
to run machine in straight lines and refrain from 90 degree turns. As this will create excess
wear of the seeding unit and possible damage to the cover wheel arm.

16
Connecting to the Seed Box
Ensure all hydraulic lines and machine connections are in correct position before operation.
Check that couplers are clicked in correctly, especially on low pressure return or case drain
hoses to avoid blowing motor seals on fan.
Checking the Wing Fold Operation
1. Ensure units are fully raised and locking pins removed before lowering or raising the wings.
2. Keep all persons away from the machine when raising or lowering wings.
3. Always locate machine on level ground when raising or lowering wings.
4. Never raise or lower wings when moving.
5. Use with care when raising wings near electricity lines to avoid contact. Serious injury or
death can result from contact with electricity lines.
Seed Unit Hydraulic Down Pressure System
NOTE: The active hydraulic system requires a tractor with closed-centre or pressure/flow
compensated hydraulics. Valve set up is on page 18.
The active hydraulic system keeps the depth wheels in contact with the soil surface to follow
ground contours over uneven terrain. The setting of the depth wheels determines seed depth,
NOT the hydraulic pressure.
The amount of hydraulic pressure needed to keep the depth wheels in contact with the surface
depends upon soil compaction, moisture and stubble covering. Too little pressure causes
insufficient spring compression and inconsistent disc penetration resulting in uneven seed depth.
Excess pressure can cause premature damage to the depth wheel tyre, rim and shaft.

17
TRANSPORT GUIDELINES
1. Proceed cautiously under overhead power lines and around utility poles.
2. Know the transport height and width of your machine.
3. Electrocution can occur with direct contact to overhead electrical lines.
4. Always fold wings fully and install transport locks before transport.
5. Do not transport with tractor that under specified for this seeder - EG: Too light.
6. When transporting, latch the tractor brakes together.
7. To improve stability when travelling through the field, wings should be unfolded from
transport position as soon as possible after leaving the roadway.
8. Adhere to recommended MAX speed 30km/h.
Transport on Public Roads
1. Always travel at a reasonable and safe speed. Never exceed 30 km/h.
2. Always use the flashing warning lights when transporting on public roadway. Keep
reflective material and flags clean and visible. Ensure oversize signs are fitted and visible –
front and rear.
3. Prevent collisions between motorist and slow-moving equipment on public roads.
4. Frequently check for traffic from the rear, especially in turns and use the turn signals.
5. Shift the tractor into a lower gear when transporting down steep slopes or hills.
6. It is not recommended to transport with seed or fertiliser in bins.
7. Never transport the machine with air seeder fan running.
8. It is recommended you check the Roads and Maritime Services website for rules and
regulations while transporting agricultural machinery in your area.
Head to the RMS website for more information: https://www.rms.nsw.gov.au/

MANUAL/ELECTRIC PRESSUE VALVE SET UP
Down pressure is important to ensure even seed depth across the machine on variable soil
conditions. But the depth wheel is the main control for depth. Each paddock can vary in soil
hardness, so adjust accordingly.
There is a Hex head screw under the manual valve. See image below.
Loosen the lock nut, to reduce pressure turn the screw anti clockwise, to increase pressure
turn clockwise.
To set pressure lower the units, drive forward five metres then check the depth wheels.
Optimum pressure you should be able to just turn the depth wheel while the disc is in the
ground. This way most of the pressure is on the disc not the depth gauge wheel. The depth
wheel is designed to follow the ground, not carry the unit or the machine.
Excess pressure will cause damage to the depth wheel rims and tyres and may void your
warranty.
Pressure ranges between 500psi and 800psi are considered to be in the acceptable range.
In some sandy and lighter soils pressures of 350 psi is recommended.
Avoid running pressures exceeding 1000psi especially for extended periods. This may
cause premature wear of the units and void your warranty.
When setting pressure, it is normal to see the pressure gauge drop 150 – 200psi quickly
and settle. This is because you are overloading the valve with oil and it will drain back to
where you have set the valve. EG. If you have set the valve at 500psi it may build up to
700psi and when you let the remote go it will quickly settle back to 500psi.
Electric Valve
Electric valve pressure is controlled by the dial on the control box in the cab. Adjust the dial
and push the remote, this will build the pressure up to where it is set on the dial and divert
the rest of the oil back to tank.
DO NOT run electric or manual pressure valves in constant flow.

MACHINE OPERATION/FIELD SET UP
 Ensure all hydraulic hoses have been correctly fitted.
 Ensure all primary breakaway couplers are correctly connected where necessary. (Tow
behind models)
 Connect all electrical plugs.
 Power up monitor and run fan, walk around seeder to ensure air is getting to all units and
there are no blockages. Turn fan off when you are happy with even air distribution.
 Calibrate product (it is recommended to use clean graded seed to prevent blockages or
bridging).
 Once desired rate is achieved you can fill bins.
 Assess paddock to be planted for conditions and stubble/trash load.
 Set estimated down pressure.
 Adjust 4 row unit depth wheels to desired depth, drive forward 20m stop and check depth
wheel is touching the surface. Try to turn the depth wheel, if the depth wheel can be turned
with some resistance pressure is ok. If the depth wheel is not touching the surface more
pressure will need to be applied. If you cannot turn the depth wheel excess pressure is
being applied and will need to be reduced.
 Check correct depth directly behind the disc is being achieved, if not change position on the
depth adjuster handle to achieve desired depth. Once desired depth and pressure are
achieved set all row units to the same position ready to plant.
 Check press wheel behind the disc is pressing over the seed in the furrow. There are
washers either side of the press wheel which can be swapped to achieve this.
 Check the rear cover wheel is closing the furrow correctly. If the ground is heavily
compacted, you may need to swap spacers on the shaft to move the wheel closer to the
furrow edge. There is also spring adjustment around the pivot at the top of the arm which
can be tightened to press firmer. If you are in soft or sandy soil you may need to move the
wheel further away from the furrow and reduce spring pressure. Image Below: Press and
