Description of Machine
The Duncan EcoSeeder is a Tee-boot drill which can be
operated as a trailing or a 3 point linkage machine.
The seed box is mounted on a robust frame
accommodating large diameter tyres for the arable
situation. The depth of the ground engaging conponents
on the 3 point linkage machine is controlled by adjusting
turnbuckles fitted to each wheel leg. For the trailing
machine, the depth is controlled by using the hydraulic
rams and depth control collars on each ram. The quality
European type peg roller seeder system handles all
seeds from turnip and rape through to peas and maize.
The seeders are driven from one of the groundwheels
via a jockey wheel system and variable speed gearbox.
For transport the drive is easily disconnected by raising
the drill to its transport height.
Working Principle
The gearbox, pegged seed rollers and seeder flaps are
set to give the desired seed rate. The coil tine and Tboot, create the seed bed. Seed flows down the flexible
tubes between seeder and tee-boot units, and drops into
the prepared seed bed.

SAFETY - General (Continued)
Appropriate Dress
Wear close fitting clothing and avoid rings or other forms of
jewellery which could become caught in the machinery.
People with long hair must have it securely fixed and confined
close to the head.
Refer to local safety standards for protective clothing and
recommended safety equipment.
Adequate protection, such as a face mask, should be worn if
operating this machine in dry and dusty conditions.
Transport This Machine Safely
Ensure that all linkage pins and security clips are fitted correctly.
With trailing machines tow with the drawbar only, as this is the
only safe towing point on the machine.
Always check that bystanders (especially children) are well clear
(front and rear) before starting and moving the tractor and the
machine.
Plan safe routes of travel, and be aware of power lines and
other roadside hazards. Take particular care when towing
implements on hillsides.
Do not ride or allow passengers on the machine.
This machine is not designed to carry passengers, and no riders
are permitted.
Road transport
On public roads,
• A speed of 40km/h must not be exceeded.
• Do not operate during the hours of darkness unless standard
lights are fitted and clearly visible. (This also applies when
visibility is limited, e.g., in foggy conditions.)
See the guidelines in the Vehicle Dimensions and Mass Rule,
issued by the Land & Transport Safety Authority.
Avoid tip-overs
Avoid holes, ditches and obstructions which may cause the
machine to tip over, especially on hillsides. Never drive near the

SAFETY - General (Continued)
Handle Agricultural Chemicals Safely
All farm chemicals should be stored, used, handled and
disposed of safely and in accordance with the supplier’s/
manufacturer’s recommendations.
Read the product label before using, noting any warnings
or special cautions, including any protective clothing or
equipment that may be required, ie. respirator.
Do not eat or smoke while handling sprays, fertilisers, coated
seeds, etc. Afterwards, always wash your hands and face
before you eat, drink, smoke, or use the toilet.
Store sprays, fertilisers, coated seeds, etc. out of reach of
children and pets, and away from food and animal feeds.
Any symptoms of illness during or after using chemicals
should be treated according to the supplier’s/manufacturer’s
recommendations. If severe, call a physician or get the
patient to hospital immediately. Keep the container and/or
label for reference.
Avoid High Pressure Fluids
Avoid any contact with fluids leaking under pressure, because
the fluids can penetrate the skin surface.
Any fluid which penetrates the skin, will need to be removed
immediately by a medical expert. Seek specialist advice on
this type of injury.
Relieve the pressure before disconnecting any hydraulic or
other lines. Make all repairs and tighten all fittings before
re-connection to pressurised fluid.
Keep your hands and body away from any pinholes or high
pressure jets. Search for leaks with a piece of cardboard
instead of using your hand directly.
Safe Work Practices
All farm machinery is potentially dangerous and should be
treated with caution and respect.
Before starting the machine, ensure that all controls are placed
in neutral and that bystanders are well clear. Check that the
guards have been securely fitted and that any adjustments
have been made correctly.
Where possible, disconnect or isolate the drive mechanism to
the implement. Lower the machine onto the ground when not
in use.
Do not operate this equipment when severe weather
conditions appear imminent.

SAFETY - General (Continued)
Practise Safe Maintenance
Keep the machine in safe working condition. Routine maintenance
and regular servicing will help reduce risks and prolong the life of the
machine.
General Maintenance
Accidents occur most frequently during servicing and repair. The
following general rules must be followed when maintaining or working
with machinery:
• All operating and maintenance manuals must be
read before and referred to while using or servicing any
piece ofequipment.
• Turn off all machinery power sources and isolate the
machine before making adjustments, doing lubrication,
repairs or any other maintenance on the machine.
• Ensure that the machine hydraulics are disconnected from
the power source.
• Wear gloves when handling components with cutting
edges, such as any ground cutting components.
• Beware of hazards created by springs under tension
or compression when dismantling or maintaining the
machine.
• It is recommended that you clean the machine with a water
blaster or similar apparatus before commencing
maintenance.
Make Sure the Machine is Well Supported
When machinery is fitted with hydraulics, do not rely on the
hydraulics to support the machine. During maintenance or while
making adjustments under the machine, always lock the hydraulics
and support the machine securely. Place blocks or other stable
supports under elevated parts before working on these.
Electrical Maintenance
Disconnect the electrical supply from the tractor before doing any
electrical maintenance.
Welding
With electronic equipment in modern tractors it is advisable to disconnect
the machine from the tractor, or at least disconnect the alternator and
battery before attempting any welding.
Use Only Genuine Spare Parts
Unauthorised modifications or non-genuine spare parts may be
hazardous and impair the safe operation and working life of the machine.
Excess lubricants must be disposed of safely so as not to become a
hazard.

Transport
1 Raise the drill into the transport position and hold at the full
extent of the rams for a few seconds to allow cylinders to
equalise.

Important - To avoid machine damage due to drill
lowering during transport, always close the hydraulic
valve at the quick release coupling. Move the handle to a
position at 90
0
to the hydraulic line
3
Maximum towing speed 40 km/hr.
For countries other than New Zealand greater speed
restrictions may apply, please refer to your local
transport authority.
Ensure towing vehicle requirements are adequate
for the towed vehicle e.g. mass, brakes. Refer to
recommendations published by the local Land Transport
Authority or equivalent.
Braking when towing can cause the load to jackknife. Use
extra care when towing in adverse conditions such as mud,
inclines and sharp bends.
Lower towing speeds are recommmended on farm roads/
tracks and where one wheel is on or over a road verge.
15
Operation
General Operation Guidelines
1 Use a sufficiently powerful tractor which is heavy enough to tow the drill safely.
2 Operate the drill at a speed of 6-12 km/hr (4-8 mph).
In stoney and uneven ground conditions a lower speed is more appropriate
3 Check that the drill is level during calibration and while seeding.
4 Check tyre pressure before seeding. Refer page 5.
5 Double check seed rates before seeding.
6 Raise the drill out of the ground when making any turns.
7 Raise the drill out of the ground before backing up.
8 Stretched sagging hoses disrupt seed flow. Slight tension may be restored by carefully shortening
the affected hose; remove from the tube at ground level and cut accordingly.
Care must be taken not to shorten too much as the tension will pull the hose from the ground tube
or damage the plastic metering funnel.
9 After prolonged storage, check to see that all drive mechanisms and hydraulic equipment are functioning
correctly. Check that the seed/fertilizer tubes are not perished or blocked.
Sowing Speed
Typical travel speeds when sowing range from 6-12 km/hr in good conditions. In stoney and uneven
ground conditions a lower speed is recommended to minimise rapid part deterioration. Sowing too fast
can result in:
1 Poor contour following and uneven sowing depth.
2 Impact damage to:
a Ground engaging components.
b Bearings, housings & axles.
c Fasteners & structural components.
3 More extreme conditions will result in greater vibration
and uneven seed flow at low seeding rates.
Sowing Depth Control
The sowing depth is dependent on:
1 The wheel height in relation to the chassis
2 Tyre pressure
3 Ground condition i.e. hard or soft
Stop collars (1) are fitted to both ram shafts. Ensure that
both rams have the same size collars fitted as these
control the sowing depth.
Pt. No. 67392
Issue 0918

16
Level Drill
Use the drawbar turnbuckle to tilt the drill so it is sitting
level. An adjustment may be required after a short period
of use because the paint wears off the discs and the discs
sharpen which in turn improves the penetration abilities.
Ensure that the front and rear rows are at an even depth.
Transport Position
When in the transport position the hydraulic cylinders are
fully extended.
Coulter Penetration Depth
To create the ideal seed bed the disc opener coulter
should cut approximately 20mm below the inverted
tee point. In hard and dry conditions this may not be
achievable, and better machine/sowing performance may
be achieved without using the disc openers. An indication
of this will be the machine bouncing which will result in
uneven sowing depth.
Coulters will give better penetration ability as they sharpen
with use.

Basic Calibration Procedure
Gearbox Setting Lever
To set the seed rate at the gearbox, slacken the tri knob (1) by
turning counter-clockwise and push from below into the position
indicated in the Sowing Chart. Retighten the star knob firmly.
When one box is being calibrated, set the other one to zero to
prevent loss of product.
Note that the front most lever (yellow letters on black
background) controls the rear box.
Important
The settings shown in the Sowing Charts (kg/ha) can only
serve as reference values. Deviations may occur caused by
differences in the size, shape, density of the seed/fertilizer and
by the dressing agent. Therefore prior to any sowing, always
carry out calibration trials to accurately determine the
actual seed rate.
Using the stepless variable speed gearbox, the speed of the
metering shaft and thus the seed rate is set steplessly. The
higher the figure indicated on the scale by the setting lever the
greater the seed rate.
Setting Seeder Shutter Slides
The varying flow properties of seeds require different shutter
slide positions which may be found in the Sowing Chart for the
individual type of seed or fertilizer. This corresponds to one of
the three settings as shown.
Bottom Flap Settings
The various seed sizes require matching bottom flap clearances
below the metering wheel. The adjusting plate allows for 10
different settings. The required position for the seed type may
be found in the Sowing Chart. The control levers are located on
the LH end of the seedbox, (opposite end to the gearbox).
Number “1” corresponds to the minimum (closed) position and
“10” the maximum gap.

Basic Calibration Procedure
(Continued)
Seed Calibration
The calibration test should be done to confirm the required
seed rate and is done with the drill stationary and level.
Seed/Fertilizer Calibration Procedures
1 Remove the calibration tray from the storage brackets
on the seedbox. Place the calibration tray (1) on the
support members below the seeders .
2 Position all the clear plastic seed diverters (2) to redirect
the seed into the calibration tray.
3 Make sure all the shutters are open and set to the
position indicated in the seed charts for the particular
seed (Page 17).
4 Agitator Shaft - Check the Seed Chart “Hints” whether
to connect or disconnect the shaft during seeding by
removing the M10 bolt (3).
5 For the test, half fill the box with seed. If this is not
possible make sure the seed is evenly distributed within
the box.
6 For setting method refer to Basic Calibration Procedures
(Page 18)
.
Note For seeds which are not covered in the Sowing Chart
(Page 17), use the figures for a seed of comparable size
and shape.
7 Place the crank handle (4) over the hexagonal drive
dog on the gearbox input shaft and turn anti-clockwise
until the seed flows consistently from the seeders. To
ensure complete filling of the seed unit continue turning
the crank until an even flow of seed is coming out of the
seeder units, then empty back into the seedbox. The drill
is now ready for calibration.
8 Turn the crank handle anti-clockwise the required
number of revolutions as detailed on the following page.
Note The Calibration is usually done for 1/40th hectare.
For very small seed rates or when using inaccurate
scales (i.e. unable to measure to the nearest gram) the
calculation based on 1/10th hectare should be used.
Scales must be accurate to 2 grams as any error will
be multiplied by either 10 or 40 giving inaccurate
calibration results.

Basic Calibration Procedure (Continued)
Hand Crank Turns for Seed Rate Calibration
The tables represented below are for arable conditions (worked ground) and
are calculated to indicate an average situation. If there is any doubt as to the
accuracy of these figures for the conditions, it is advisable to run checks on
the calibration figures listed. Refer Page 22, (Wheel Slip Deviations).
9 Weigh the seed collected during the test in kilograms.
Caution: Scales must be accurate to 2 grams, as any error will be multiplied
by either 10 or 40, giving inaccurate calibration results.
10 Calculate the seed rate by multiplying the kgs previously collected x 40 (1/40th
ha method) or x 10 (1/10th ha method) depending on the requirement. If the
resultant calculation does not produce the desired seed rate use the enclosed
seed rate calculator disc to determine the correct gearbox setting.
Refer Use of Seed Rate Calculator Page 21.
Suggestion: To be on the safe side and until confidence has been gained
with the method of calibration it is advisable to conduct a second test at the
newly determined gearbox setting.
11 Where a coated seed is used it is advisable to check the calibration after
1 hectare as dressings can tend to create a coating on the seed metering
wheels thus changing the the flowing properties of the seed which in turn
alters the seed rate.
For 1/40 Hectare (250m2) Calibration
Seed Rate = Actual Seed Collected (kg) x 40
For 1/10 Hectare (1000m2) Calibration
Seed Rate = Actual Seed Collected (kg) x 10

Basic Calibration Procedure (Continued)
Use of Seed Rate Calculator
Determining the gear box scale setting using the calculator.
Usually the first calibration test yields a different seed rate. However with the value determined
from the first test it is possible to determine the correct gearbox setting with the aid of the
enclosed disc calculator. The disc calculator consists of 3 scales. An outer white scale (1) for
all seed rates above 30 kg/ha and an inner scale (2) for all seed rates below 30 kg/ha. On the
middle coloured scale (3) are all the gearbox setting numbers to a maximum value of 100.
Setting Example (Desired Seed Rate 125kg/ha)
1 From the calibration procedure at a gearbox lever setting of “70”, a seed rate of 175 kg/ha
is obtained.
2 Turn the inner disc until the measured seed rate of 175kg/ha (A) is in line with the related
actual gearbox setting of “70”(B).
3 Read off from the disc rule the necessary gearbox setting for the required seed rate of
125kg/ha (C). In this example the correct setting is “50” (D).
4 To be on the safe side the new gearbox setting can be checked by another calibration test.

Basic Calibration Procedure (Continued)
Calibration Deviations
Deviations Between the Calibration Test and the Actual Seed Rate
The most frequent cause for changes between the calibration test and the seed rate lies in the
flowing properties of seed during sowing. These changes in properties generally result from
reactions of the dressing agents to temperature, humidity or abrasion. These changes will
become even more obvious when the bottom flaps are incorrectly set. If the setting of these
flaps leaves too large a gap an uncontrollable additional flow of seed can occur during seeding;
especially when assisted by the drill bouncing, a condition not simulated while conducting the
calibration tests. For this reason the basic setting of the bottom flaps should be checked at
regular intervals.
Residues from the seed dressing on the bottom flaps and metering wheels can also influence
the flowing properties of the seed and thus the seed rate. In such cases a balance will occur
only after a period of time and it is recommended to repeat the calibration test to confirm the
seed rate after 2-3 seedbox fillings, nominally when the seed box is half empty. Only then will a
balance occur and the seed rate will stabilise.
Wheel Slip Deviations
It is always possible with rubber tyred drills in extreme ground conditions to get wheel slip. Not
normally a problem with cleated type tyres in good condition, but more so in the arable situation
with the less agressive tread patterns. The result: large differences between the calibration test
and the actual sowing rate, obviously less seed deposited than required. The number of crank
turns indicated on page 20 is correct in most circumstances other than those mentioned above.
To check number of crank turns for calibration
Should you require to check this in a practical way proceed as follows:
For an area of 250m
2
(1/40 Hectare), the travel distance for your machine is shown below. Place
the crank handle over the hexagonal drive dog on the gearbox. Move the machine forward over
the measured distance, counting the number of turns of the crank handle as you go. Using this
number of crank turns repeat the calibration.

Basic Calibration Procedure
(continued)
Sowing of Fine Seeds
For sowing small seeds the EcoSeeder Drill is equipped
as standard with a combined normal and small seed
metering wheel (1). During grain sowing and other larger
varieties of seed both the large and small seed metering
wheels are coupled and both rotate. In order to convert the
seed drill to sow fine seed insert the crank handle and rotate
clockwise until the holes
(2) of the small seed wheel are
visible.
Using the tool supplied (3) disengage the the pin inside
the hole so that the large metering wheel rotates freely
on the metering shaft.
When seed is to be sown again using the normal metering
wheel press the pin, using the tool, from the large metering
wheel side (opposite direction to before), back into the
hole of the small seed wheel thus reconnecting the drive
between the two.
This must be done for the whole bank of wheels.

Caution - When resetting the metering
wheels on the seeder shaft
Care should be taken when tightening the grub screws
on the small seed wheel. Adjust the grubscrew until the
movement of the metering wheel just stops, then tighten
no more than 1/8 of a turn.
Do not overtighten as this can result in breakages while
operating and may void the warranty on these units.
