Description of Machine

The Duncan Ag Vineyard Seeder is either a single curved disc or double disc drill with dual boxes for seed and fertilizer. The drill is carried and operated from the three point linkage of the tractor. The sowing depth control is achieved from two trailing wheels with individual wheel retraction stops. The right hand depth control wheel is also the drive wheel for the seeder unit. Awide variety of seeds can be sown from the seed box, from small seeds like turnip and rape to large seeds like peas and maize. The machine has a calibration system for setting seeding rates prior to operating, which is very simple and accurate to use.

Working Principle

The gearbox, pegged seed rollers and seeder flaps are set to give the desired seed rate. The disc(s) create the seed bed. Seed flows down the flexible tubes between the seeder and the coulter casting 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.

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,

• Aspeed 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 edge of a gully or steep embankment - it might cave in. Slow down for hillsides, rough ground and sharp turns.

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. respirtor.

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.

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 of equipment.

• 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 three point linkage as high as possible to

maximise ground clearance. Ensure ground clearance is sufficient. Do not transport with the wheels in contact with the ground.

2 Ensure that all linkage pins and security clips are fitted and

are secure.

3 Ensure that the jack stand has sufficient ground clearance.

Raise into the upper position if required.

4 Ensure lighting and oversize warning requirements meet

recommendations published by the local Land Transport Authority or equivalent.

Maximum towing speed 40 km/hr.

For countries other than New Zeaand 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.

Lower towing speeds are recommmended on farm roads/tracks and where one wheel is on or over a road verge.

Operation

General Operation Guidelines

1 Use a sufficiently powerful tractor which is heavy enough

to operate 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 3. 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 Ensure the jack stand is in the raised position. 9 After prolonged storage, check to see that all drive

mechanisms and hydraulic equipment are functioning correctly. Check that the seed 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 Dragbar spring pre-compression. 3 Tyre pressure. 4 Ground condition i.e. hard, soft, how even.

The wheel height in relation to the chassis is controlled using the wheel retraction stop. To adjust the wheel height;

a Lift the drill using the three point linkage sufficiently to

unload weight on the wheel.

b Loosen the M12 nyloc nuts on the clamp plate

assembly (1).

c Remove the R clip and pin (2). d Adjust the wheel retraction stop (3). e Refit the pin, R clip and retighten the nyloc nuts.

Refer Fig 1.

A more consistant sowing depth is acheived with minimal dragbar deflection. With harder ground conditions more spring pre-compression may be required. Adjust the M10 plain nuts (1) as desired. Refer Fig 2. Note, less spring pre-compression will allow the disc to ride over rigid obstacles, eg stones.

In bumpy or undulating ground conditions the drive wheel will drop away from the wheel retraction stop to maintain seeder drive.

Avoid sowing through dips with a rigid top link. Excessive loads will be transferred through the linkage stays to the wheel which may cause componentry damage. If possible use a floating top link. When sowing over ridges the drive wheel may loose contact with the ground temporary.

Disc penetration ability will improve as discs sharpen with initial use.

Basic Calibration Procedure

Gearbox Setting Lever

To set the seed rate at the gearbox, slacken the star knob (1) by turning counter-clockwise and push from below into the position indicated in the Sowing Chart. Retighten the star knob firmly (Fig 3).

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 grain 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 (Fig 3).

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. This corresponds to one of the three settings in Fig 4.

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 (Fig 5).

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 Calibration Procedures

1 Remove the calibration tray from the storage brackets

on the seedbox. Place the calibration tray (1) adjacent to the seeder units (Fig 6).

2 Position all the clear plastic seed diverters (2) to

redirect the seed into the calibration tray (Fig 6).

3 Make sure all the shutters are open and set to the

position indicated in the seed charts for the particular seed (Table 2. Page 14.

4 Check the Sowing Chart ‘Hints’ (Page 14) to see

whether to connect or disconnect the agitator shaft by removing the lynch pins (1) during seeding (Fig 7).

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 Procedure

(Page 15)

Note For seeds which are not covered in the Sowing Chart (Page 14), use the figures for a seed of comparable

size and shape.

7 Place the crank handle over the hexagonal drive dog on

the gear box and turn clockwise until the seed flows consistently from the seeders (Fig 8). To ensure complete filling of the seed unit continue turning the crank until the calibration tray is approximately half full then empty into the seedbox. The drill is now ready for calibration.
