Agrowplow – Company Profile
Agrowplow Pty Ltd is an innovative, soil conscious company committed to developing "Soil Care" products for
improved, sustainable agriculture.
The founders of Agrowplow had the foresight to see that farmers needed to improve their practices - to improve soil
structure, increase humus and allow more water to infiltrate and store in the soil - if farming was to be sustainable.
The first Agrowplow was designed and built in 1977 to improve soil structure, increase humus levels and increase
water infiltration and storage deep into the soil.
Today the company's range of Agrowplows and Agrowdrills are widely accepted by farmers and agricultural
researchers for their unique capabilities. The term "Agrowplow" has become a "farming concept" rather than just
another implement.
The company's range of specialised Agrowplows, Agrowdrills and other products are designed and manufactured
under strict code of sustainable agricultural mechanisation, and promoted under the slogan:
"Prosperity Through Soil Care"
The company's research and development division develops world leading technology for Agrowplow which has
resulted in a well-earned reputation of turning market "Ideas" into reality.
Development is undertaken with the professional guidance of fully qualified design engineers with the use of 3D
CAD/CAM that supports the complete design to manufacture process. All designs are manufactured to the highest
standards of quality control.
Agrowplow has a large factory area (3500 square metres) with extensive fabrication equipment. Experienced and
qualified personnel form an extensive resource in all areas.
Agrowplow - building soil care products for improved, sustainable agriculture.

Diagnostic Time
Warranty does not cover time required to diagnose a warranty problem. Diagnostic time is affected greatly by the
training and expertise of the technician employed to do the job. With proper training of service personnel, diagnostic
time should be at a minimum. Agrowplow expects that Dealers will assign a well trained and proficient technician to
handle warranty repairs.
Non – Genuine Parts
Use of parts other than Agrowplow parts for repair of warranted parts will automatically negate any warranty.
Warranted components must be replaced with genuine Agrowplow repair parts.
Unauthorised Repairs
Repairs by an unauthorised agent will automatically forfeit any warranty. Warranty repairs must be carried out by an
Authorised Agrowplow Dealer only, and only after Agrowplow’s authorisation has been obtained.
Special Warranty Considerations apply in respect to the following:

Completing Safe Use Instruction (SUI) & Pre Delivery Inspection (PDI)
Reports
The use of the SUI and PDI Reports is mandatory. Each Report must be completed as part of the sales process of
every machine and returned to Agrowplow for warranty registration. Each completed Report must detail:
1. The intended purpose of the machine;
2. The safety controls that have been used to reduce or eliminate identified hazards;
3. A warning of the existence of hazards remaining in the machine and an explanation as to why the hazard
remains.
4. Limitations to the use and application of the machine or plant resulting from any remaining hazards as
recorded on the SUI Report.
5. Further operator training that may be required.
Special Note:
Dealers are responsible by law to determine that machines are suitable and properly equipped for the application they
know or should reasonably have known the machine will be used for. This implies that a supplier must enquire what
the machine is to be used for, and a further review of safety controls must be carried out, in view of the specific
application the machine to this intended purpose.
At the time and point of delivery the salesperson must present the SUI & PDI Report to the purchaser as a record of
the installation process. This should be the result of a face to face installation.
Once the intended purpose is confirmed, use each item of the SUI as the record of instruction given to the purchaser
including:
•
•
•
•
Safety controls that minimise the hazards present in the machine;
Safe operating procedures for the proper use of the machine;
Limitations to the use of the machine according to an intended application that prevents a safety hazard
arising;
Any additional training the operator may require to use the machine safely
The purchaser must sign the completed SUI as evidence that information and training has been provided and that the
purchaser now has the responsibility to train all other operators. It is the responsibility of the purchaser to ensure all
other operators are trained.
The original SUI and PDI forms must be completed, signed and returned to Agrowplow for Warranty to be valid

1. Safety
Agricultural machinery presents an operator with hazards associated with setting up, on and off road transport,
tillage and seeding applications, as well as machine service and maintenance. The operator must be aware of these
hazards.
The dealer will explain the capabilities, safe application, service requirements and restrictions of the machine and
demonstrate the safe operation of the machine according to Agrowplow’s instructions. The dealer can also identify
unsafe modifications or use of unapproved attachments.
The following publications provide information on the safe use and maintenance of the machine and attachments:
•
•
The operator’s manual delivered with the machine gives operating information as well as routine
maintenance and service procedures. It is a part of the machine and must stay with the machine if it is sold.
Replacement operator’s manuals can be ordered from your Agrowplow Dealer.
The machine has decals that instruct on safe operation and care.
1.1.
Shared Responsibility for Safety
1.1.1. Why is farm safety important?
Farming is dangerous. Farms have many conditions that create dangerous situations including increasing use of
machines and chemicals, confined spaces, live animals, constantly changing weather conditions, very young and very
old people and continual financial pressure to get crops in and harvest off on time. As any combination of these
factors can become lethal, control of occupational health and safety risks has become an essential farm management
competency.
Taking risks with the lives of family members or employees is not something that should ever be contemplated!
Farm accidents are often workplace accidents of a different kind. While any workplace accident is a tragedy, a farm
accident is often a family disaster where a breadwinner, grandparent, child or other family member is injured or
killed. At times the tragedy is made worse by the fact that another family member may have caused the accident and
is charged with an offence under occupational health and safety legislation.
Considering that the likelihood of an accident can be significantly reduced by people being more safety conscious,
safety should be a topic of frequent discussion among family members and farm employees. Children also need to be
trained to recognise hazards and to never use machinery as a plaything, as they too can play a role to remind others
to never take safety risks. The loss of fun that kids might otherwise have on machinery is nothing compared to the
grief of harm done to a child.

1.1.2. Four Big Reasons Why Safety Is Important
Accidents Hurt
Accidents Cost
Accidents Involve Others
Accidents Can Be Avoided
1.1.3. How to Create Safety Awareness
The Safety slogan – ‘Think it, Talk it, Work it’, summarises what we all must do to make workplaces that are without
risk to the extent that is reasonably practicable. Assuming that the chain of responsibility is working as it should,
Agrowplow Operators Manual
P a g e | 11
machinery will be properly guarded, safety switches fitted and proper information given by way of Operator
Handbooks, decals, verbal instruction and so on to all relevant personnel.
Risk awareness and proper use of a machine is the result of an employer having been given relevant information,
taking safety seriously, and ensuring that each operator of a machine is properly trained and supervised.
1.1.4. Consultation
Providing information is a good beginning. Each employee must then be free to further discuss safety related matters
and ask for further assistance from your employer, Health and Safety Representative, or workplace OH&S Authorities
if required. Consultation is always best if it is done cooperatively, as part of the way business is normally done, at
smoko discussions or at more formal meetings depending on the topic and your business situation.
Ultimately, we are only safe at work when everyone who is responsible for safety has played their part and the
employer, supervisor and the person using a hazardous machine “thinks it, talks it and works it”. Safe working
conditions are the result of a safety culture in which everyone participates, where it would be unacceptable to
behave any other way.
1.1.5. Hazard Identification
A hazard is something that has the potential to cause harm to a person. Where you are now there may be hundreds
of hazards. Some hazards have so little potential for harm, due to their likelihood, that we can disregard them. Other
hazards, because of the real and likely potential for serious harm, must not only be identified, but also controlled so
as to eliminate or reduce the potential for harm to a person.
1.2.
Safe Operation
This section offers general guidelines for the safe operation of machinery. It does not replace local, state or federal
safety regulations.
Agrowplow has made every effort to highlight all risks to personnel or property. Owners and operators have a
responsibility to exercise care and safe work practices at all times in the vicinity of the machine. Owners are advised
to keep up to date on safety issues and to communicate these to all users of the machine. If you have safety concerns
specifically related to this machine, contact your dealer immediately.
1.2.1. Operator Safety
Read this manual carefully before operating new equipment. Learn how to use this machine safely. Be thoroughly
familiar with the controls and the proper use of the equipment before using it.
Take careful note of all safety instructions both in this manual and on the machine itself. Failure to comply with
instructions could result in personal injury and / or damage to the machine. Replace missing or damaged safety
decals on the machine and ensure that these remain clearly visible.
It is the owner’s responsibility to ensure that anyone who operates, adjusts, lubricates, maintains, cleans or uses the
machine in any way has had suitable instruction and is familiar with the information in this manual. Operators and
other users of the machine should be aware of potential hazards and operating limitations.
•
•
•
1.2.2. Have Training with Actual Operation
Operator training must consist of a demonstration and verbal instruction.
This training is given by your dealer when the machine is delivered.
New operators must start in an area without bystanders and use all the controls until they can operate the
machine safely under all conditions of the work area.
Agrowplow Operators Manual
P a g e | 12
•
•
•
•
1.2.3. Know the Work Conditions
Operators must know any prohibited uses or work areas. They need to know about excessive slopes and
rough terrain.
Operators must know the local road transport regulations, and understand the dangers and requirements of
transporting wide and heavy equipment.
Always wear protective clothing when servicing the machine.
For operators to be qualified, they must not use drugs or alcoholic drinks that impair their alertness or
coordination while working. Operators who are taking prescription drugs must get medical advice to
determine if they can safely operate a machine.
1.3.
Warning Decals
Safety Warning Decals are a means of communication the presence of hazards and appropriate risk controls to
machinery operators.
•
•
Do not remove any safety instruction decals.
Ensure that any safety decals are clear and visible. Clean and replace as necessary.
1.3.1. Hazardous Machinery
Misuse or incorrect operation on any machine could cause serious injury or death to either the operator or
bystanders. It is important to always fully read the Operator’s Manual and understand all operating and safety
procedures before using the machine. If you have any queries relating to safety or the operation of any machine
contact your Agrowplow dealer immediately.
All guards and safety devices must be kept on the machine and maintained in a functional condition. If necessary to
remove guards or safety devices for maintenance they must be replaced before commencing operation.
Sound the horn before starting the machine and before moving off to alert bystanders of your intentions. Bystanders
must also be well clear of the machine before operating.
Hazardous Machinery Decal
Agrowplow Operators Manual
P a g e | 13
If the machine is to be left unattended the hydraulics must be lowered and the engine stopped. This will prevent
accidental operation of the machine.
1.3.2. Bystanders
Do Not Operate Near Bystanders Decal
Do not operate any agricultural machinery near bystanders. Serious injury or death to bystanders could occur if they
come in contact with projectiles, chemical spray, fertiliser and/or grain dust and moving machinery.
Sound the horn before starting the machine and before moving off to alert bystanders of your intentions. Make sure
bystanders are well clear of the machine before operating.
1.3.3. Machinery Safety Guards
Rotating or Moving Machinery Decal
Safety hazards related to exposed drive belts, pulleys, chains, sprockets and other mechanisms must be clearly
identified and properly guarded. Some hazardous mechanisms like tynes and coulter discs cannot carry out their
intended function if they are guarded and must, therefore, be controlled by an alternative means. Guards must be
fixed in place with bolts, locks or fasteners that require a tool or key to remove them.
Always wear Personal Protective Equipment (PPE) including overalls whilst operating the machine. Loose items of
clothing, jewellery (including watches), or long hair could all become entangled in rotating or moving parts causing
serious injury or death.
Keep clothing and body extremities well clear of pinch points while the machine is operating. Keep well clear of
moving parts at all times. These include drive chains, sprockets, shafts, wheels, discs, pivot points, etc. Guards are
Agrowplow Operators Manual
P a g e | 14
provided with the machine for safety reasons where practical without compromising machine performance. Ensure
these are always fitted during operation.
1.3.4. Hydraulic Fluid Penetration
A hydraulic fluid leak can, under high pressure, penetrate a human body
Appropriate risk controls must be established to safe guard against hydraulic fluid penetration. All hydraulic
machinery should be inspected regularly. Worn hoses and faulty connections, valves or cylinders, must be repaired or
replaced.
Operators should be warned that, in some cases, residual pressure can remain in a hydraulic system after it is shut
down. In these situations the cause of the residual pressure needs to be identified and controlled to avoid the
possibility of a high pressure hydraulic fluid leak or the unintended operation or movement of the machine or
attachment.
Hydraulic Fluid Penetration Decal
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.
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.
To eliminate the risk of serious injury or death:
•
•
•
•
Repair or replace all possible causes of leaking hydraulic fluid, including:
o Faulty valves, cylinders and components;
o Worn hoses and fittings.
Train operators to shut down pressure pumps or pressure sources before coupling or uncoupling hydraulic
connectors
Never use bare hands to check hoses for leaks. Use a piece of paper to detect a high pressure spray
Use Personal Protective Equipment.
Instruct operators to wear protective equipment, including safety glasses, if there is a high likelihood of a high
pressure hydraulic leak.
Agrowplow Operators Manual
P a g e | 15
1.3.5. Hot Components
During operation hydraulic components such as motors, pumps and valve blocks can become quite warm. Do not
touch these components until they have cooled down otherwise serious injury such as burns could result.
Heat Source Decal
1.3.6. Three Point Linkage
Three Point Linkage Decal
The three point linkage on a tractor creates numerous pinch and crush points that could cause serious injury or death.
Keep well clear of this area when the engine is running.
Shut the engine off for all attachment, un-attachment and maintenance in this region.
1.3.7. Service Access
Using incorrect access points could result in serious injury or death as a result of slipping and / or falling. Agricultural
machinery contains many sharp edges and points. Some of these can and should be guarded, whilst other sections
cannot be guarded without compromising the working function of the machine.
Always use access platforms and access ladders to carry out maintenance or refilling. If maintenance is required on
parts of the machine not serviced by an access platform always use a ladder or some other form of access device.
Agrowplow Operators Manual
P a g e | 16
Do Not Climb On This Machine Decal
Do not ride on, or allow passengers on, the machine. Under no circumstances are passengers to be permitted on the
machine while it is in operation or being transported. Any platforms and/or steps are provided solely for the purpose
of preparing the machine for use.
Do Not Enter This Area Decal
Always shut the engine off before climbing into, onto or under machinery. If engines are operating power could
accidently be directed to components in these areas and cause serious injury or death.
Always keep clothing and hands clear of all engine driven components. Serious injury or death could result by contact
with fast or powerful components.
Engine Driven Components Decal
Agrowplow Operators Manual
P a g e | 17
1.3.8. Handle Agricultural Chemicals Safely
Chemical Hazard Decal
All farm chemicals including fertilisers should be stored, used, handled and disposed of safely and in accordance with
the 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.
Do not eat or smoke while handling chemicals, fertilizers or coated seeds. Always wash your hands and face before
you eat, drink or use the toilet.
Store chemicals, fertilizers and coated seeds 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 manufacturer’s
recommendations. If severe, call a physician or get the patient to hospital immediately. Keep the container and/or
label for reference.
1.3.9. Controlling Noise
Noise Exposure Decal
Excessive noise levels can cause permanent hearing impairment. The incidence of hearing impairment increases as
the exposure to noise increases. Noise levels are cumulative and increase with each extra noise.
Noise can be reduced by eliminating sounds. Isolate noisy operations by making sure that they are carried out away
from other people.
Provide sound reducing equipment such as a cab on a tractor. Avoid using noisy equipment if possible.

Raised Wings
Raised Wing Decal
A failure of the wings mechanical lock or a failure in the hydraulic circuit can cause the rapid collapse of the wing
itself. Contact with a falling wing can cause serious injury or death by crushing, impalement or other forms of trauma.
1.4.
Ergonomic Safety
1.4.1. Personal Protective Equipment
Employers must provide a safe workplace for their employees.
Employers are responsible to ensure that Personal Protective Equipment (PPE) is available for use in situations where
it makes a practical contribution to controlling hazards and safety risks.
Employers must also ensure that PPE is in good condition and is properly used by employees.
1.4.2. Working at Heights
Where work is required at heights where a fall of more than two meters is possible, operators must be aware of
hazards caused by:
•
•
•
Unstable, sloping or slippery surfaces;
Proximity to unguarded edges;
Other non-fall hazards.
Risks must be controlled by the most practicable of the following means:
•
•
•
Do the task at ground level
Use suitable equipment that provides a solid elevated working surface
Use fall prevention system (safety harness)
Agrowplow Operators Manual
P a g e | 21
Ladders are the least preferred means of working at heights and should only be used when there is no viable
alternative such as:
• Stairs
• Cherry picker
• Portable steps
• Forklift with appropriate platform
• Scaffold
Emergency procedures including first aid must be available.
A safety harness must also be used where required by the nature of the task.
Where employees must work at height in situations including servicing of machines proper equipment, such as a
ladder and proper training in its use and emergency procedures must be provided.
In other situations where employees must often or always work at height a proper scaffold or mobile platform must
be provided which provides a solid working surface. Other potential hazards that may cause falls, such as fatigue
from using a spray gun and exposure to paint fumes must be minimised.
1.4.3. Manual Handling
Manual handling injuries relate to a range of conditions including:
•
•
•
•
•
Muscle sprains and strains
Back injury
Soft tissue injury
Hernias
Chronic pain
Some of these injuries are known as repetitive strain injury (RSI) or Occupational overuse Syndrome (OOS) but all are
generally known as Musculoskeletal Disorder (MSD) resulting from manual handling.
All work activities must have manual handling hazards identified, risks assessed and controlled. Some tasks have a
very high risk of MSD evident from an assessment of the task, or reports of previous injuries. Assessment should
include a review of:
•
•
•
•
•
Postures
Movements / distances moved
Forces and type of loads
Duration and frequency of activity
Environmental factors including vibration / heat / cold
A suitable checklist is available from WorkCover to ensure your assessment is systematic and facilitates consultation
with employees.
Where practicable, tasks causing MSD must be eliminated, or the risk reduced by altering the machine or process to
something less risky, according to the hierarchy of control such as:
•
•
•
•
Eliminating the task
Substituting the task with another less risky task
Using mechanical aids
Improved work layout / seating
Agrowplow Operators Manual
P a g e | 22
•
•
•
Improved work systems including job rotation or rest periods
Providing training
Using personal protective equipment
Implement and review controls to ensure they are properly used and effective.
As MSD is a complex subject with significant risks that are not immediately obvious, it is suggested a high degree of
employee consultation is used and professional assistance is sought if you are unsure of the best approach.
Typical examples of MSD injuries in automotive workshops include:
•
•
•
•
Bending over mudguards for long periods
Working with your hands above your head for long periods
Applying high force to levers, spanners, etc. for long periods
Lifting heavy weights such as tyne assemblies
Use good mechanical handling equipment, such as hoists, jacks and wheel lifters as much as possible.
Review all tasks where employees work in unusual postures for long periods, or have to exert great effort, and
develop improved job methods to reduce MSD injuries.
When MSD injuries are reported, risk assessments must be reviewed and all hazards identified and risks controlled.
1.5.
Maintenance
1.5.1. Practice 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 before commencing maintenance.
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.
Extreme caution should be used when clearing coulters, tynes or soil openers. These may be very sharp and
cause serious injury.
Use due care when adjusting or maintaining any aspect of the Agrowplow. Failure to do so may result in
serious injury.
Agrowplow Operators Manual
P a g e | 23
1.5.2. Electrical Maintenance
Disconnect the electrical supply from the tractor before doing any electrical maintenance. When welding with
electronic equipment in modern tractors and on machinery it is advisable to disconnect the machine from the tractor
or at least disconnect the alternator and battery before attempting any welding.
1.6.
Transporting the Machine
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 are clear 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 pull trailed Agrowplows with any vehicle other than a tractor.
In most instances the weight of the Agrowplow exceeds the unbraked towing capacity of the tow vehicle (except
tractors). Not only is this unsafe it will also void the vehicle manufacturer’s warranty.
Do not ride or allow passengers on the machine. This machine is not designed to carry passengers and therefore no
riders are permitted at any time.
Please consult your local transport authority regarding the use of ‘Oversize’ signs, escort vehicles and lighting
equipment when transporting agricultural machines on public roads.
When transporting the machine:
•
•
•
•
•
•
•
•
•
•
A speed of 30 km/h must not be exceeded. Transporting at greater speeds will result in loss of implement
control and cause serious damage or injury.
Do not transport the Agrowplow without the tractor drawbar being in a locked position. Transporting
without the drawbar locked will result in loss of implement control and serious damage or injury.
Do not transport an Agrowplow with a vehicle of less gross mass than that of the Agrowplow being towed.
Transporting with a smaller lead vehicle will result in loss of implement control and cause serious damage or
injury.
Make sure the Agrowplow does not exceed the unbraked towing capacity of the lead vehicle.
Do not pull trailed Agrowplows from any point other than from the tractor drawbar. Pulling from a point
other than the designated tractor drawbar can result in tractor instability and cause serious damage or injury.
Do not operate when visibility is limited e.g. in foggy conditions. Do not operate outside daylight hours
unless lights are fitted.
Please consult your local road transport authority for road use e.g. Oversize Transport.
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 as it might cave in.
Slow down for hillsides, rough ground and sharp turns.
1.7.
Un-Hitching the Machine
When unhitching the Agrowplow:
•
•
Always unhitch on a solid, flat surface
Always lower the hydraulics of the machine. The Agrowplow is more stable when the undercarriage is
resting on the ground than if it is left in the raised position. Machines left in the raised position are
susceptible to hydraulic failure causing the machine to crash to the ground and a rapid discharge of
Agrowplow Operators Manual
P a g e | 24
•
•
pressurised hydraulic fluid. Lowering the Agrowplow to the ground will also relieve pressure from the
hydraulic circuit making it safer and easier to connect and disconnect the hydraulic couplings.
Always place chocks behind and in front of the wheels to prevent accidental movement on the machine.
Always lower the jack stand to 'take the weight' of the A-frame. This will provide further stability to the
parked Agrowplow.
1.8.
Risk assessment
The table on the next page is a guide to assess the severity of hazards associated with the machines use. The columns
listed include:
•
•
•
Hazard Type – lists hazards for assessment and notes whether they are relevant to the machine
Cause of Hazard – lists the area or application of the machine which applies to the hazard
Risk Control – lists appropriate safety measures to protect personnel and equipment from damage or harm
The risk assessment rating is calculated from the following table by taking the value for ‘Risk Severity’ and adding it to
the value for ‘Likelihood of Occurrence’.
RISK ASSESSMENT
Rate the severity & likelihood of any hazards present within the machine
RISK SEVERITY
4 = Possible fatality
3 = Major injury
2 = Minor injury
1 = Negligible injury
LIKELIHOOD OF
OCCURRENCE
4 = Very likely
3 = Likely
2 = Unlikely
1 = Very unlikely
FREQUENCY
If the exposure to a hazard is very frequent eg continuous, compared to weekly,
monthly etc, this should be reflected in increased likelihood of occurrence.
Add the Risk Severity to the likelihood of Occurrence to calculate the Risk Assessment Rating
The Risk Control measures listed should be in accordance with the following risk assessment ratings:
• Less than 3 – Low Risk, Acceptable Hazards
Issues to be reviewed with regularity but no specific action is required. Machine usage with awareness.
• 3 to 4 – Medium Risk, Hazards to be managed
Decals or warning signage should be fixed in reasonable locations. All personnel who interact with the machine
should be warned of the hazard. Operators to be trained to never operate machine when safety measures are
not being adhered to.
• 5 and higher – High Risk, Unacceptable Hazards
Operators must be trained to check that no risk of this hazard is present before or while using machine and must
never use the machine when any risk of this hazard is present.

2. Soil Care System of Farming
The origins of Agrowplow began with observation and concern about devastating effects of conventional cultivation
on Australian soils.
Today, Agrowplow remains focused and dedicated to the development of innovative farming practices and
equipment to improve and protect our nation's greatest asset - the soil!
2.1.
Soil Degradation
Traditional cultivation and sowing techniques, which require soil to be ploughed and cultivated before sowing, have
caused erosion by wind and rain and severe break down of soil structure. Continual passes of the tractor and
deterioration of soil structure have also formed compacted layers below the soil surface.
These soil damaging factors combine to seriously limit plant growth and yields, and erode our precious asset. In the
case of compacted layers water absorption is prevented and root growth is restricted, prohibiting the plants access to
nutrients.
Helpful soil microbes and earthworms are reduced or eliminated because poor soil structure causes pastures to
become water-logged quicker, dry out faster, and often make tillage operations almost impossible.
Traditional cultivating practices are always aimed at controlling weed growth and preparing a fine "seedbed".
Unfortunately these practices destroy soil humus, expose soil particles to erosion, compact the soil, restrict moisture
infiltration, reduce root growth and lower plant yields.
In order to maximize farming profits while still protecting the environment these problems must be overcome.
The "Soil Care System" approach to farming is different because it promotes the health of both "seed-bed" and "root
bed" in a sustainable way - working with nature rather than against it.
New farming techniques are evolving together with new equipment to give simple, logical compatible answers.
2.2.
The Solution
Agrowplowing, or non-inversion tillage, as well as direct drilling provide positive answers to sustaining soils for highly
productive farming. The Agrowplow Soil Care System of Farming encompasses these techniques.
The Soil Care System of Farming has been developed to provide farmers with better returns from their crops and
stock. It advocates no tillage or minimum tillage because of moisture losses and soil degradation brought about by
each cultivation. These methods can be used in a variety of ways to suit each soil and seasonal condition for creating
healthier, sustainable root bed and seed bed environments.
The unique range of specially developed Agrowplows and Agrowdrills are machines which will allow you to obtain the
best advantages of non-inversion tillage, direct drilling and minimum tillage practices - for crop and pasture
establishment in conservation farming systems.
2.2.1. Agrowplowing or non-inversion tillage
Non-inversion tillage is lifting and shattering hard soil pans without soil inversion. The task is accomplished with
minimum soil surface disturbance ensuring that precious top soil is left on the surface and minimal moisture is lost to
the atmosphere.
Agrowplow Operators Manual
P a g e | 27
Top soil is not mixed with less fertile subsoils or less fertile subsoils mixed with fertile top soil. The topsoil remains
virtually undisturbed and is less susceptible to wind and water erosion than conventionally cultivated soils.
The patented design of the Agrowplow shank prepares and renovates the root zone of the soil without inversion.
This unique ability of root bed renovation improves water infiltration, humus levels, soil structure and sustainable
productivity. Root development is enhanced by an unrestrictive soil environment.
2.2.2. Direct Drilling
No-Till or direct-drilling is the term given to establishing crops and pastures without any prior tillage. Control and
reduction of vegetation and weeds is achieved by either chemicals or livestock or both.
Non-inversion tillage and direct drilling go hand-in-hand. Direct drilling promotes the benefits of Agrowplowing
reducing risk of erosion and prolonging the effect of deep ripping through less soil traffic. This leads to reduced
compaction and enhanced root growth encouraging healthier and deeper soils.
2.3.
Soil Compaction
Soil compaction is a form of soil degradation. It strangles the life out of soil and severely impacts on yields. Yield
losses of up to 40% are not uncommon. In extreme cases yields can be reduced by up to 80% and severe erosion can
occur.
2.3.1. Causes of Soil Compaction
Soil compaction is caused by normal farming activities including using tractors, implements, headers, vehicles,
cultivation, livestock and irrigation.
The weight of vehicles and livestock compress the soil. Cultivation breaks down soil aggregates, soil structure,
porosity and humus. The worst damage occurs in wet soils, with high stocking rates, frequent vehicle traffic and
intensive cultivation. Any activity which reduces the porosity or bulk of your soil is causing soil compaction.
Compacted soil becomes denser leading to decreased porosity of the soil. This causes reduced:

•
•
•
Water infiltration
Humus levels
Soil aeration
Worm activity
Microbe activity
Water retention
Root growth
Crop yields
Agrowplow Operators Manual
P a g e | 28
Everyday farming activities cause compaction
2.3.2. How is Soil Compaction Rectified?
Step 1
Break up compacted soils, hard pans, clay pans, tillage pans and impenetrable barriers with an Agrowplow.
Step 2
Re-establish plants with strong, deep root systems to rebuild and hold the soil structure, bulk and porosity in a
healthier state - preferably using direct drilling or minimum tillage techniques.
Step 3
Use farming practices which minimise soil cultivation, soil inversion and traffic in wet soils.
2.4.
Advantages of Agrowplowing
Agrowplows are used for both primary and secondary tillage. They work without soil inversion and therefore
minimise moisture loss. The narrow edge on tyne design substantially reduces tractor horsepower requirements.
The low angle digging tool and narrow shank of the Agrowplow ensures that the previous crops root systems are fully
retained in the soil. This improves structure, adding humus, increasing water infiltration and holding moisture whilst
allowing greater utilization of nitrogen created by legume Rhizobium bacteria.
The Agrowplow can be successfully applied in most situations. It has been used extensively in the farming of cereal,
cotton, sugar, vegetables, vineyards and orchards under both dry land and irrigation farming methods.
Agrowplowing is particularly effective in pasture renovation and the control of water run-off, allowing infiltration and
storage within the soil. Wind erosion is reduced and salinisation problems can be reduced.
Hardpans and barriers, created by fine particles moving downwards into the coarse soil structures creating an almost
impenetrable layer, can be eliminated.
Agrowplow Operators Manual
P a g e | 29
It should be noted that hard pans can be re-established quickly unless tractor traffic is reduced. Normal cultivation
requires many more passes of a tractor than direct drilling.
Measurements from many soil types indicate that the depth of the traffic compaction layer varies according to soil
type. Generally, the lower the clay content of the soil, the deeper the hard pan formation.
The following factors should be considered before soils are Agrowplowed:
•
•
•
•
•
•
•
Soil type
Soil Moisture
Shank spacing
Time of working
Speed of working
Depth of working
Crop type
2.4.1. Unique Shank Design
The unique Agrowplow shank is set to work below the compacted plough pan to uplift and shatter it without
inversion of the soil. Soil particles become aerated without violent separation while allowing greater moisture
infiltration into the seed bed. This minimizes fine soil aggregates and creates conditions ideal for microbial action.
Crop roots are then free to pursue moisture and nutrients deep in the soil. Crop rotation and the planting of deep
rooted species also assists in developing and maintaining a healthy root bed.
The Agrowplow has been engineered to operate in a wide range of soil conditions whether they be black, heavy soils
or the light, sandy, abrasive types. Soil type does not affect successful Agrowplowing or non-inversion tillage.

2.5.
Benefits of Direct Drilling
Direct drilling prevents the soil from being exposed to wind and water erosion and the effect of reduced traffic
minimises soil compaction. Zero cultivation avoids degradation of soil structure.
The primary reason for cultivation is to kill vegetation that consumes moisture from the soil. This can now be
achieved by alternative methods.
A big advantage of direct drilling is that it allows soils to improve and become more friable with time. As increased
organic matter is retained and broken down, it is combined with the soil as humus. Soil structure is improved by this
organic matter, making it more porous for better aeration and water infiltration.
The reduction of soil compaction (due to less traffic and soil degradation) allows full moisture retention to be
achieved. The plant can then use the soils full potential of stored moisture, and can pursue water and nutrients deep
into the soil.
Studies have shown that earthworm levels have increased by using this method. Soil microbes are also returned to
the soil and these beneficial organisms aerate the soil. This further helps to break down organic matter and make
nutrients available.
Utilising chemicals and livestock, modern farming is able to control weeds and maintain a good ground cover. Erosion
is therefore reduced and evaporation is kept to a minimum.
As the cost of farming continues to rise over the next decade any increase in margins is an advantage to farmers.
Compared to conventional cultivation, direct-drilling will save time and money, and also reduce replacement
expenditure on plant and equipment.
Look at the advantages enjoyed by farmers who have adopted direct-drill and minimum-tillage techniques:
•
•
•
•
•
•
•
•
Improved soils
Reduction of capital costs by up to 40%
Greater length of grazing time (between two and four months), allowing carrying capacity to be lifted in
mixed enterprises
Flexibility in cropping programs
Yields superior to conventional cultivation
Reduced labour requirements - less time is spent on the tractor
More control over timing of sowing and related activities
Reduced costs of production

Features of the Agrowdrill
The Agrowdrill is the most robust, versatile direct drill available in Australia. It maximises seeding versatility for
pasture renovation, summer crops, cereals and legumes – from specialised direct drilling to traditional farming
applications.
The Agrowdrill range is designed to meet a wide range of farmer and contractor needs in cropping and pasture
applications. Each machine is capable of doing a number of jobs which enables the capital investment on machinery
to be minimized. Agrowdrills can be used in a range of one pass direct drilling and conventional cropping practices,
and can handle most seed and fertiliser types.
Agrowplow Operators Manual
P a g e | 32
There are a number of crucial features and options of the Agrowdrill which allow it to perform well in tough
conditions. These include:
•
•
•
•
•
•
•
Extremely rugged construction with plenty of frame weight to penetrate the soil
Flexi Coil spring release tyne with a high breakaway force capabilities
Two versions are available – 350lb and 550lb
Very strong coil tynes with a high breakaway force which maintain the crucial digging angle and position of
the soil opener
The use of inverted “T” (Baker Boots) soil openers
Strong coulter design
Wide variety of soil openers to suit varying soil conditions
2.7.
Advantages of the Baker Boot
The following outlines essential differences between the Baker Boot, disc seeder and conventional tynes and openers
used for direct drilling.
2.7.1. The Baker Boot
The action of the Baker Boot is quite different to the other openers used in direct drilling. The Baker Boot opener is
capable of producing the most ideal environment for maximum seed germination and plant establishment, especially
in drying soil conditions.
There is little smearing or compacting of the soil as the opener passes through the soil. Therefore the tiny roots of
emerging young seedlings easily enter the soft earth and quickly support the plant. In drying conditions the
germination and plant growth obtained from direct drilling with the Baker Boot is radically superior to other openers.
The Baker Boot has no moving parts and the very narrow profile gives lower draft requirements, easier penetration
and less wear.
The use of coulters minimises soil disturbance and improves trash handling.
Seed placement in different furrow types
Agrowplow Operators Manual
P a g e | 33
2.7.2. Conventional Tynes
Conventional tyne seeders mainly use a cultivating point which operates at a shallow angle to the soil. The action of
the tyne and the digging tool tends to lift the soil and throw it to both sides leaving a U-shaped slot.
Few conventional seeders are fitted with coulters and consequently have difficulty handling the large amounts of
surface trash often encountered when direct drilling. The action of the tyne tends to drag trash along with it.
The disadvantages of conventional tynes are as follows:
•
•
•
•
•
•
Poor trash handling ability
Dry the soil with a wide furrow, exposing moist soil
Poor accuracy placing the seed and seed may end up near the surface, not in contact with moisture
Have higher draft requirements due to the width of the digging point and the aggressive action of moving the
soil up and to the side
The digging tools often have a high wear rate
The need for prior cultivation can damage soil structure
Moisture loss in different slot types
2.8.
Planning to Direct Drill
Planning is the key to direct drilling and reduced tillage techniques. Planning must take into account gross margins,
marketing (if applicable), paddock history, crop rotation, soil type, fertility (using soil tests), weed history and
densities as well as long term development plans. Flexibility of operation is also essential.
2.8.1. Weed Control
Good weed control is essential for successful establishment of a new crop or pasture.
Weed control is one of the main reasons for traditional cultivation practices - the ground-engaging tool physically cuts
and tears the roots of unwanted plants from the soil.
Agrowplow Operators Manual
P a g e | 34
Direct drilling calls for a different approach. Some of the alternatives available for weed control include:
•
•
•
•
Heavy grazing
Spraying with herbicides
Slashing
A combination of the above
2.8.2. Timing
Timeliness of the seeding operation is critical for good germination, growth and best yield results.
There are two main aspects of timeliness you must consider:
•
•
Always check the optimum seeding date for your district and seed on time
Ensure the best use of available moisture after rain by seeding while the soil is moist
2.8.3. Seed
Use only good quality certified seed. Certified seed is guaranteed to meet a minimum standard germination
percentage and to be free of weed seeds and impurities. Use the recommended seeding rate.
Your seed supplier or your local advisory officer can tell you how many kilograms per hectare (kg/Ha) you should sow.
Adequate plant population will also help your establishing crop or pasture compete with weeds.
Be sure to inoculate legume seed with the correct strain of Rhizobia bacteria. Failure to inoculate could lead to a
poor pasture stand. Talk to your seed supplier about inoculation and ask them to supply the inoculant.
Your seed supplier will also be able to advise about chemical protection of your seed for insect attack and various soil
borne diseases.
2.8.4. Seed Placement
Accurate seed placement is crucial for successful germination. Seed should always be covered and in contact with
moist soil. Seeding depth varies with species and is generally related to seed size.
Small seeds generally need to be placed shallow. The Agrowdrill is capable of placing seed accurately at any depth
from a few millimetres down to 75mm (3”). Ask your seed supplier or advisory officer how deep you should be
sowing and adjust the Agrowdrill accordingly.
The Agrowdrill can be set up to seed at various row spacing’s. Sowing row spacing, if coulters are not fitted, can be
virtually infinite.

2.8.5. Ensure Adequate Plant Nutrition
Most soils are low in fertility and need to have nutrients added to boost pasture and crop growth. Young plants
especially need good nutrition.
The need for fertiliser can be assessed in a number of ways:
•
•
•
•
Paddock history
The vigour of existing vegetation
Chemical soil tests
Trial plots
Advice on fertiliser requirements can be sought from government advisory officers, agricultural consultants or
fertiliser companies.
Fertilisers are available in many different forms and can be applied in many different ways. The Agrowdrill can
“band” artificial fertilisers close to the seed and provide nutrition where it is most need.
2.9.
The Job’s not finished at seeding!
Careful preparation and seeding of a crop or pasture are only the first steps in the management process. There is a
great deal of careful management practises needed after the Agrowdrill has given your seed the best chance of
establishment.
2.9.1. Weed control
Effective weed control can be the difference between a profit and disaster. Good weed control before seeding will
ensure emerging seedlings have a good start and an even better finish.
Certified seed, adequate fertility, correct seeding rates and placement of seed will put the odds in your favour for
good germination and emergence.
The management practices after emergence however are just as important. Inspect your crop or pasture regularly for
weed growth. If weeds become a problem you have a number of options open to you:
•
•
•
•
Use a selective herbicide to kill weeds
Strategic grazing or slashing can help reduce weed growth
Applying fertiliser may help in some situations
Cutting hay can remove weeds.
2.9.2. Insect Pest Control
Insect pests can seriously damage emerging or established crops and pastures. During your regular inspection you
should also be on the lookout for insects. Consideration of the following points will help prevent or eliminate insects:
•
•
•
Grow species or varieties that are resistant to the common pests in your area
Use treated seed
Spray only if absolutely necessary.
Note: Information on chemical control of weeds and insects should be available from government advisory officers,
agricultural consultants, chemical resellers or spraying contractors.
Agrowplow Operators Manual
P a g e | 36
2.9.3. Use of Fertiliser
Maintaining good nutrition is important for sustained production
All crops and pastures can benefit, in some situations, from additional fertiliser after seeding. Fertiliser can be added
in many forms.
2.9.4. Grazing Management
New pastures can usually only stand light grazing in the first season. Perennial crops can also be grazed.
The following are some important points to remember:
•
•
•
•
Graze only when plants cannot be pulled out
Graze heavily for short periods to remove weeds.
Some species need to set seed each year, so allow this to take place.
Allow plenty of time for the pasture to recover after grazing.

4. Farmscan Jackal Hectaremeter
The electronic Farmscan Jackal Hectaremeter is designed to fit virtually any farm tractor. It displays and records area
sown and displays working speed in either metric or imperial units.
Farmscan Jackal Hectaremeter
Please consult the Farmscan Jackal Operators Manual for installation and operation procedures.
The wiring harness for the Farmscan Jackal is incorporated into the main wiring harness of the Agrowdrill.
Calibration factors for specific models of Agrowdrill are supplied in Section 6.3 of this manual.

Please see Section 9.4 for troubleshooting instructions.
Agrowplow Operators Manual
P a g e | 42
5. Operating Instructions
5.1.
Hitching and Levelling
The Agrowdrill should be matched to the tractor size to maximise performance and efficiency. A mismatched tractor
and implement will be inefficient and cost money, as well as being unsafe.
5.1.1. Three Point Linkage Models – Agrowseeder Only
The three-point linkage lift capacity of the tractor will generally determine the required tractor size. Check the tractor’s
operator’s manual for details.
It is essential that the tractor be front weighted when using the Agrowdrill. The Agrowdrill is very heavy when the
hoppers are filled and will transfer weight off the front wheels. This can be very dangerous in hilly areas and when
travelling at speed on the road. Consult the tractor’s operator’s manual for recommendations.
The Agrowdrill must be level while operating. The hitching and levelling procedure is as follows:
1. Attach and level the Agrowdrill laterally (side to side) using the screw adjustable linkage arm.
2. Set both depth wheels evenly at the desired working depth and tighten the locking collar or retaining bolt
firmly.
3. Set the fore-aft level using the tractors adjustable top link. The front and rear depth must be equal.
4. Start working at the desired depth and observe the level of the machine from both the side and the rear.
5. Readjust and repeat the above procedure if necessary.
6. Retighten the locking collar on the top link after completing adjustments.
It is very important that the Agrowdrill be levelled correctly to achieve good results. As a final check, dig to the bottom
of the furrow at two or three points across the working width of the machine and check the seeding depth. Ensure
that the front and rear tynes are seeding at the same depth.
Three point linkage stabiliser bars must be used at all times. Adjust the stabilisers to bring the Agrowdrill directly behind
the tractor, allowing only slight side-to-side movement.
The tractor’s three-point linkage system should be operated in the ‘float’ mode allowing the Agrowdrill to be supported
by the depth wheels and to follow the ground contours. Consult the tractor operator’s manual for details.
5.1.2. Hitching
The hitching procedure is as follows:
1. Pin the tractor drawbar into the central position.
2. Attach the Agrowdrill to the drawbar and set the adjustable levelling tube so that the machine is approximately
level.
Warning: Ensure the drawbar pin is locked into position so that it cannot work itself out when the machine is in
operation or transit. Failure to do this may result in serious injury or death.
3. Attach the hydraulic coupling to your tractor remote outlet, taking care to clean away any dirt.
The working depth of a trailing Agrowdrill is controlled by the hydraulic rams attached to the wheel assemblies.
These are operated by the remote hydraulic system.
On some tractors it is necessary to set the hydraulic system to operate in the “single acting” or “bypass”.
Consult the tractor operator’s manual.
4. Connect wiring harness.
Agrowplow Operators Manual
P a g e | 43
5. Disengage the jack stand and adjust the hitch level to suit the drawbar height of the tractor. When level,
ensure the levelling tube is locked using the locknut.
5.1.3. Hydraulic Lift Circuit
The procedure to connect and prime the hydraulic lift circuit is as follows:
1. Ensure both the tractor remotes and the hose couplings are clean and then connect to the tractor.
2. Loosen the hydraulic connector on the input line of the right hand wheel lift cylinder. This should be done to
allow air to escape while the hydraulics are being primed.
Right Hand Wheel Lift Cylinder
3. Slowly pressurise the hydraulics until oil appears at the loosened connection on the right hand cylinder.
Note: Stand well clear of the loosened connection as oil under pressure can spray wildly outwards. It is a good idea to
place a hessian bag or similar material over the connection to minimise oil movement.
4. Retighten the connection as soon as oil appears.
5. Continue to prime the hydraulic lift circuit until the right hand cylinder is fully extended. Hold the hydraulics
open for a further 15 to 20 seconds to allow air to clear from the circuit.
6. Fully raise and lower the machine several times to expel any residual air trapped in the circuit.
The lift circuit is now fully primed and the Agrowdrill can now be moved.
Agrowplow Operators Manual
P a g e | 44
5.1.4. Coulter Hydraulic Lift Circuit – AD 520 Only
The procedure to connect and prime the coulter hydraulic lift circuit is as follows:
1. Ensure both the tractor remotes and the hose couplings are clean and then connect to the tractor.
2. Disconnect cylinder from coulter bar and allow bar to lower to ground. This allows the cylinders to extend
during priming without twisting the bar and damaging the slides.
3. Loosen the hydraulic connector on the input line of the right hand coulter lift cylinder. This should be done to
allow air to escape while the hydraulics are being primed.
Right Hand Coulter Lift Cylinder
4. Slowly pressurise the hydraulics until oil appears at the loosened connection on the right hand cylinder.
Note: Stand well clear of the loosened connection as oil under pressure can spray wildly outwards. It is a good idea to
place a hessian bag or similar material over the connection to minimise oil movement.
5. Retighten the connection as soon as oil appears.
6. Continue to prime the hydraulic lift circuit until the right hand cylinder is fully extended. Hold the hydraulics
open for a further 15 to 20 seconds to allow air to clear from the circuit.
7. Reconnect coulter bar to hydraulic cylinders.
8. Fully raise and lower the machine several times to expel any residual air trapped in the circuit.
The coulter lift circuit is now fully primed.
5.1.5. Levelling
The Agrowdrill must be level while operating. The levelling procedure is as follows:
1. Start working at the desired depth and observe the machine from both the side and the rear.
2. Adjust the levelling tube so that the machine is level from front to rear.
3. Retighten the locking collar on the levelling tube when adjustments are completed.
Agrowplow Operators Manual
P a g e | 45
It is very important that the Agrowdrill be levelled correctly to achieve good results. As a final check, dig to the
bottom of the furrow at two or three points across the working width of the machine and check the seeding depth.
Ensure that the front and rear tynes are seeding at the same depth.
5.2.
HydraDisc Undercarriage - AD 820 Only
The breakout of the disc assembly in controlled via a hydraulic recoil system. The system is pressurised from oil in the
tractors hydraulic system. As the disc assembly encounters an obstacle the oil is forced out of the cylinder back into
the circuit increasing the pressure in the accumulator. When the obstacle is cleared the accumulator forces the oil back
into the cylinder returning the shank to its operating position.
The pressure in the operating system can be adjusted according to the operating conditions by increasing or decreasing
the oil level in the circuit. A shut off valve is located near the base of the accumulator to either open or close the circuit
from the tractors hydraulic system.
Agrowplow recommends an operating pressure of 400 PSI for the hydraulic circuit.
Do not exceed 2500 PSI in the system as this is approaching the operational limits of the hoses, cylinders,
accumulators and fittings. Agrowplow will not be held responsible for any failure, injury or death resulting from the
operation outside of these parameters.
5.3.
Seeding Depth
Seeding depth will vary depending on the species being sown. Generally speaking, small seeded species should be sown
shallower. Larger seeded species will emerge if sown deeper.
The following are important guidelines:
•
•
•
Seeding deeper than recommended will drastically reduce the chances of good germination and emergence.
In hot, dry conditions the topsoil will tend to dry out rapidly and lead to poor germination.
In wet, cool conditions the topsoil will remain moist and shallow placed seed will germinate effectively.
Consult a seed reseller or Advisory Officer for a recommendation regarding seeding depth if unsure.
5.4.
Row Spacing
The row spacing of the Agrowdrill is infinitely variable unless coulters are fitted. The only restriction will be the number
of outlets on the hopper.
In some conditions it may be advantageous to seed in 135mm rows eg Irrigated Lucerne or Ryegrass. Other crops or
pastures may require a wider spacing eg Sorghum at 350mm.
Consult a seed reseller or Advisory Officer for a recommendation regarding row spacing if unsure.
5.5.
Coulter Settings
The soil openers must be adjusted to run exactly behind the coulter whilst the machine is operating. If the opener is
running off line of the coulter the soil will not be sliced in the correct position leading to trash build up and a greater
soil disturbance.
To adjust the spacing of the soil openers:
1. Position the Agrowdrill with the tynes and coulters resting on a hard surface such as a cement floor.
2. Observe coulters and tynes noting any misalignments.

9.
Lift the Agrowdrill and secure using the ram safety stoppers.
Loosen the frame clamp retaining bolts on the opener assemblies.
Adjust so the soil openers align with the coulter blades.
Retighten all retaining bolts.
Lower the Agrowdrill and recheck alignment.
Repeat and adjust if necessary.
Recheck and tighten frame clamp bolts after 30 minutes of operation.
The Agrowdrill can be equipped with either plain or fluted coulters. Key factors to consider when choosing the type
of coulter are:
•
•
Plain Coulters
o Used where best appearance of the finished job is required.
o Used in harder soil where maximum penetration is required.
o Lower wear rate than fluted coulters
Fluted Coulters
o Perform better in very heavy trash conditions.
o Cause less smearing in clay type soils.
o More aggressive soil surface disturbance.
5.6.
Operating Speed
The Agrowdrill will produce the best results if operated between 4 and 8 km/h. Optimum speed will vary with the soil
type, vegetative cover and root matter present.
Operating at higher speeds will increase soil surface disturbance, reduce penetration and seriously reduce the accuracy
of seed and fertiliser placement. High speeds will also increase wear on the openers.
5.7.
Hopper Selection
The metering system in all hoppers is identical meaning seed or fertiliser can be used in any hopper. In deciding which
hopper to use it may be necessary to take into account and blending or banding options that may be used.
The following points must be considered when deciding which hopper to use:
•
•
•
For a majority of seeding jobs a greater quantity of fertiliser than seed will be required. On all models except
the Agrowseeder the front hopper has a larger capacity and therefore will give a greater efficiency. The
Agrowseeder only has one hopper compartment.
Depth placement and / or blending requirements.
Fertiliser is generally denser than seed. Putting fertiliser in the front hopper will bring the Agrowdrill’s centre
of gravity forward.
For hopper capacities refer to the specification in Section 3.0.
5.8.
Electric Clutch
All trailing Agrowdrill models are fitted with an electric clutch. The clutch is operated by the switch on the in-cab control
box.
The clutch engages when the switch is on and disengages when the switch is in the off position.
Agrowplow Operators Manual
P a g e | 47
To activate the clutch simply turn the green toggle switch on.
In-Cab Control Box with Clutch and Light Switches
5.8.1. Mounted Trip Switch
Models fitted with the trip switch have the added feature that the seed drive will switch on as the machine is lowered
and switch off as the machine is raised. The clutch switch needs to be in the ‘on’ position for the seed follow, and
with the added trip switch switches the seed flow off when the machine is raised.

6. Calibration Instructions
6.1.
Adjusting the Seed and Fertiliser Rates
Adjusting the seed and fertiliser rates on the Agrowdrill is very simple as it only involves three components:
• Variable Speed Gearbox.
• Restrictors applied to the fluted rollers.
• Adjustable gates under the fluted rollers.
All three may need to be adjusted.
6.1.1. Gearbox Adjustments
The unique gearbox of the Agrowdrill allows adjustment of seed and fertiliser rates over a wide range by simply
adjusting one lever for each.
The rate adjustment levers are on the left hand side of the machine. The lever closest to the front of the machine
adjusts the front hopper.
To adjust the rates simply rotate the handle in an anticlockwise direction to loosen and slide the lever up or down the
scale as required - an increase in number indicates an increase in speed. Once at the necessary position rotate the
handle in a clockwise direction to lock the lever in place.

The fluted rollers (identical for both seed and fertiliser) have a coarse side and a fine side.
This design allows both large and small seeds to be accurately metered. The Agrowdrill can handle a wide range of
seed sizes with the minimal adjustment of fitting or removing restrictors.

Depending on the model of Agrowdrill, the gate adjustment levers are located on either the right hand end of the
Agrowdrill or in the centre of the machine underneath the hopper.
The gate settings are based on seed size. Do not adjust the gate settings to increase the application rate.
Adjust gate settings as follows:
1. Check the gate setting recommendation for the seed or fertiliser being used (see above table in section 6.2.1).
2. Loosen the Knob (rotate in an anticlockwise direction) slide the lever up or down the scale as required. Once
at the necessary position lock the lever in place (rotate the knob in a clockwise direction).

Non Standard Machine Settings
For machines with configurations or tyre sizes not listed in the calibration tables the following procedure will need to
be followed:
1. Establish the working width of your drill.
1.1. Measure the row spacing in metres.
1.2. Multiply this figure by the number of rows on your machine.
2. Determine the rolling circumference of your drive wheel.
2.1. Ensure the tyre is inflated to recommended pressure.
2.2. Lift the machine into transport position.
2.3. Mark the tyre at contact point with the ground.
2.4. Place a peg or marker at this same location.
2.5. Tow the machine for x number of wheel revolutions. The greater the number of revolutions used the more
accurate the calculation.
2.6. Measure the distance travelled (in metres) and divide by x to obtain the rolling circumference.
A list of tyre sizes with their respective rolling circumferences is presented in the following table. These rolling
circumferences are based on the tyre manufacturers recommended pressures.

Plotting Calibration Charts
This procedure will allow for the plotting of calibration charts for seeds or fertilisers not listed or for the modification
of existing charts.
1. Set the rate adjusting lever to the maximum setting and carry out the calibration procedure as outlined in the
Section 6.2.1 above.
2. Select a blank chart (or draw a new one) suitable to the seeding rate achieved.
3. Find the point on the x-axis (bottom) that corresponds to the achieved seeding rate.
4. Mark a point on the maximum rate adjustment setting line that corresponds to the achieved seeding rate.
5. Draw a straight line from this point to the bottom left hand corner (0,0).
This line indicates the approximate amount of seed or fertiliser rate at any given rate setting.
Blank tables have been supplied in section 10.
Agrowplow Operators Manual
P a g e | 59
7. Operating Tips
7.1.
After the First Round
The following is a list of points that should be checked after the first pass or round of a paddock:
1. Ensure both the seed and fertiliser drives are rotating.
Note: Problems in this area can be avoided with adequate maintenance and checking the rotation of the drives before
commencing.
2. Check that the seed and fertiliser are running evenly through all rows.
3. Ensure that the bottoms of the delivery tubes are not blocking up with wet soil. If this occurs the soil should
be allowed to dry before continuing.
4. Check the soil openers for any loose bolts.
5. Check the rotation of coulters.
6. Check the machine for any loose bolts.
7. Check the alignment of the coulters and the openers.
8. Retention all tyne and coulter clamps.
7.2.
Gradual Slowing of Fertiliser Flow
This often happens when using fertilisers such as single super that have a high percentage of fine powder. The powder
generally builds up at the bottom of the fertiliser hopper and slows the flow rate. This may also occur with lime-coated
seeds, as the lime is prone to flaking off.
To avoid this problem, occasionally run the fertiliser hopper to a low level and clear away any powder build up manually
by opening the gate settings to the widest setting. Only do this while the machine is stationary.
7.3.
Seizing of the Metering System
This can easily happen when using highly soluble and corrosive fertilisers such as urea. Such fertilisers will ‘cake’
rapidly in moist conditions and may seize the fluted rollers.
This can be avoided by never leaving the Agrowdrill filled with fertiliser or seed in moist conditions.
7.4.
Checking the Rotation of the Drives
The rotation of the seed and fertiliser metering mechanism can be easily checked by ‘ratcheting’ the rate adjustment
levers. Simply loosen the knurled knobs and move the lever backwards and forwards a number of times. This will
rotate the drives allowing the following to be done:
•
•
•
•
Check if the metering system is seized with ‘caked’ fertiliser.
Free small blockages caused by ‘caked’ fertiliser. If the ‘caking’ is severe the hopper may need to be cleaned
out manually.
Check for blockages in the fluted rollers, delivery tubes or soil openers.
The quantity of seed and fertiliser under each opener should be observed to ensure equal metering of seed
and fertiliser across the width of the machine.
Agrowplow Operators Manual
P a g e | 60
7.5.
Cleaning Seed and Fertiliser Hoppers
Thorough cleaning of the seed and fertiliser hopper is very important for a number of reasons including:
•
•
•
Fertiliser left in the hopper will cause corrosion of the metal parts of the Agrowdrill.
If you are changing to a different seed all the previous seed must be removed to prevent contamination.
Seed left in the Agrowdrill will attract mice, rats and insects.
The following is the procedure for cleaning:
1. Try to have as little seed or fertiliser as possible remaining after finishing the seeding.
2. Scrape all the remaining seed or fertiliser to one side and scoop into bags or buckets. Sweep the bottoms of
the hoppers clean with a broom.
3. Remove all restrictors and open the gates under the fluted rollers. For end of season cleaning remove verandas
to allow easier cleaning.
4. Use an air compressor or water hose to blow or wash out any remaining seed or fertiliser. A vacuum cleaner
used to suck out remaining seed or fertiliser also works well.
5. Close the gates under the fluted rollers and reinstall the restrictors into the desired location. Replace the
verandas.
6. Clean away any seed or fertiliser that may have spilled onto the frame of the Agrowdrill.
Note: If the Agrowdrill is washed with water allow the hoppers to dry out thoroughly by placing the Agrowdrill in the
sun with the hopper lids open.
When the Agrowdrill is clean and dry, apply a light coating of diesel to the insides of the hoppers to prevent any
corrosion from fertiliser.

Move the tensioner up or down until the desired chain tension is achieved.
Retighten retaining bolt.
If the chain tension is still insufficient a link may need to be added or removed from the chain.
8.12. Drive Chain Maintenance
The drive chains will benefit from some form of lubrication. The two recommended methods are:
•
•
Oil chains regularly during seeding using a quality chain oil.
Remove the drive chains annually and store them in a pot of quality chain oil.
Note: The most crucial measure to ensure long chain life is to avoid leaving the Agrowdrill exposed to the weather
between seeding jobs.
8.13. End of Season Storage
To ensure a long and trouble free working life please take the following steps when storing the Agrowdrill for long
periods.
•
•
•
•
Clean out the hoppers thoroughly according to the procedure outlined in section 7.5.
Shed the Agrowdrill for protection against the weather.
Ensure chains are properly oiled and covered before storage or remove chains and store them in an oil bath.
Ensure all grease nipples are thoroughly greased before storage. By excluding air and moisture from inside the
bearings the chance of corrosion will be minimised. For best results grease the bearings while they are still
warm from the last working.
SIMPLE ROUTINE MAINTENANCE WILL PROLONG THE LIFE OF THE AGROWDRILL

Farmscan Jackal Hectaremeter
The Problem

Probable Cause / Remedy
Check that power cable connections at battery are clean and tight
Measure voltage from power cable at monitor connection point. It should be
between 12 – 13.8 V DC
If voltage ok and unit fails, return to nearest Farmscan dealer or authorised
service agent.
Check that calibration factors H1 and H2 are correct
Is the machine overlapping or underlapping?
Is the unit counting headlands?
Switch to SPEED readout and make sure it is reading at a constant speed.
Cable or sensor could be damaged if readout is jumpy.
Is the magnet facing the sensor end to end?
Is the correct magnet being used?
Is the magnet too far away from the sensor? (3-5mm gap)
Is the magnet staying in line with the sensor on corners?
Is the wheel loose?
Is the sensor on a non-driven wheel? Tractor drive wheels will cause an over
reading.
Replace wheel / shaft sensor if none of the above.
This is normal if TOTAL hectares are above 999.9, or it is extremely cold.
Speed must be above 2.0km/h to register.
Check that the calibration factors H1 and H2 are correct.
Check that gap between magnet and sensor is 3 - 5mm
Press TOTAL or TRIP key first to select area to be cleared.
RESET key must be pressed and held down for at least 3 - 4 seconds
If hectares still fail to reset, return unit to nearest Farmscan dealer or
authorised service agent.
Switch off all other electronics to eliminate electrical interference as the cause.
If switching off other electronics eliminates the fault, ensure the Hectaremeter
cables are not running alongside wiring from other electrical devices, and / or
physically move the Hectaremeter in relation to the other equipment.
If petrol engine in close proximity, stop the engine to see if interference is
caused by ignition system.
Note: Carbon ignition leads must be fitted to spark plugs and coil to stop
interference.
Disconnect Sensor from cable at wheel / shaft. If the problem stops, replace
the sensor.
Make sure the Hectaremeter has an independent power cable, wired directly to
the battery + and – terminals.
If unit still counts hectares, return unit to nearest Farmscan dealer or
authorised service agent.

10. Calibration Charts
Due to variations in seed sizes that can occur from crop to crop, season-to-season as well as normal variations
between varieties, the information given on the following charts should be used as a guide only. Cleanliness of
samples will also effect actual rates, especially with oaten and some barley varieties.
For total accuracy it is recommended that you check the rate of flow from the metering system for each seed and
fertiliser to be used. This will provide very accurate rates of seeding, and can be recorded for future reference. Blank
charts have been provided for you to record your own specific charts for future use.
Correctly calibrating the Agrowdrill at each change of seed, fertiliser or application rate will prevent any undesired
metering rates. The calibration procedure is outlined in section 6.2.
