INTRODUCTION
Welcome to the Sheep Auto Drafter user manual. In it you will find instructions
on using the Sheep Auto Drafter and drafting unit as well as hints to help you
resolve any problems you encounter.
In designing the Sheep Auto Drafter, Gallagher have continued their tradition of
creating products which are functional, practical, easy to use, innovative, and in
tune with the needs of the rural market. The use of a ruggedized composite as
the main construction material is a breakthrough innovation in stock handling
equipment design which comes with a wide range of benefits.
What is the Sheep Auto Drafter?
The Sheep Auto Drafter is a sheep handling unit containing an integrated
weighing platform which will connect with a variety of brands of electronic
scales. Pneumatically operated gates at either end of the auto drafter allow stock
in and out. These can either be controlled automatically, by setting up some
conditions in the scales, or manually by the stock handler.
Each side panel contains antennae to allow reading of Electronic ID (EID).
The sorting unit links with the Sheep Auto Drafter to automatically draft stock.
The conditions for drafting are set up in the scale indicator attached to the Sheep
Auto Drafter. Drafting can also be controlled manually by the operator. An extra
sorting unit can be linked end to end to enable up to 5 way drafting.
The Sheep Auto Drafter and sorting unit have both been constructed from
composite materials. They are lightweight, making them easy to transport and
set up, extremely durable, and because of the forgiving nature of composite they
are safe for you and your stock.
When the Sheep Auto Drafter is combined with the sorting unit you can carry out
a range of activities including: automatic Electronic ID (EID) reading, weighing
and drafting.
The Sheep Auto Drafter can be operated from a distance using a remote control.

Benefits of using the Sheep Auto Drafter
The benefits you will receive from using the Sheep Auto Drafter include the
following:
•Save time and labour
One person can operate the Sheep Auto Drafter using a remote control. This
means that you will still be in control of its operation while at a distance.
Additionally, as you control the gates by using the remote control, the
physical demands of operating gates, particularly drafting gates, is removed.
•Improve work efficiency
Increase the speed of a variety of stock management tasks and also drafting
throughput as the process can be automated. This means stock (and people)
spend less time in the yards.
•Decrease the incidence of injuries for stock and handlers
The Sheep Auto Drafter is made from composite materials. The chances of
injury from collisions or general usage are significantly lower as composite is
far more forgiving and there are no sharp or protruding edges. Additionally,
the flooring has been designed to provide safe footing so slipping does not
occur. All of the moving parts e.g. rams, are protected by guards ensuring
there are no trapping points. Additionally, they are substantially lighter than
traditional systems, making them much easier to shift.
•Quiet operation
The innovative composite construction of the Sheep Auto Drafter and the
pneumatic gate operation mean that it is exceptionally quiet when working.
This reduces the stress on you and stock. Stock will flow better and will
enter the unit more readily as a result.
•Carry out several stock management tasks at the same time
The Sheep Auto Drafter can automatically read EIDs, weigh and then draft
without you having to control it. All of these actions can be pre-programmed
into a scale indicator which will communicate with the Sheep Auto Drafter.
This gives you the freedom to move away from the weighing and drafting
area, to organise stock at the same time as these actions are occurring.
•Easy allocation and drafting of stock into different management groups
Providing your brand and model of weighing indicator supports it, it is a
simple process to allocate animals into groups so that they can be managed
differently. This could include such things as: the division into different
groups by weight to allow priority feeding, or the drafting out of ewes with
multiple pregnancies.
•Improve stock flow through the weighing and drafting system
As there is less human involvement in the weighing and drafting process
stock feel less threatened and more inclined to move freely through the
system.
•Decrease drafting and weighing operator errors and hit the correct target
market weight when drafting

3E2374 Sheep Auto Drafter User Manual
Page 9
As the weighing and drafting processes are automated there is less chance
of error. In addition, accurate weighing and drafting ensures that all stock
fall into the correct groups to ensure they achieve premium prices at sale.
Scenarios for use
The flexible nature of the Sheep Auto Drafter allows you to carry out many
activities simply and easily. These include:
Automatically
•Weighing animals and releasing them, or drafting them using the weight
groupings you have set up in your scales.
•Reading EIDs and weighing animals, then drafting using the weight
groupings you have set up in your scales (draft by weight).
•Reading EIDs then drafting using a set of conditions you have set up in your
scales (draft by list) (the range of options will be dependent on the brand
and model of the attached weighing indicator).
Manually
•Controlling the movements of animals out of the Sheep Auto Drafter
yourself.
•Overriding an automatic setting to retain an animal in the unit so that you
can examine it for some reason, or draft it in a different direction from the
automatic setting.
•Temporarily pause an automatic operation so that you can resolve issues,
for example if two animals become caught in the Sheep Auto Drafter.

SETTING UP FOR SUCCESS
Positioning the Sheep Auto Drafter
It is recommended for best performance that the Sheep Auto Drafter is mounted
on a hard, level, flat surface. Ideally, particularly for permanent installations, a
concrete pad of approximately 900cm (wide) by 2600cm (length) should be laid
to fit the Sheep Auto Drafter and a single sorting unit. They should be bolted to
it using the mounting holes provided (see Figure 3). It is recommended that 4
M10 x 125mm masonry anchors with 10mm x 25mm flat washers and a masonry
drill (bit size of 10mm) are used to attach the Sheep Auto Drafter and sorting
unit. A permanent mounting also allows for the optimisation of surrounding
yards and races to efficiently feed stock into the weighing and drafting set up.
Figure 3. Mounting hole.
Power and compressed air requirements
Both power and compressed air are necessary to operate the Sheep Auto Drafter
and sorting unit. An air supply is needed to operate the unit entry and exit gates
and also the drafting gates.
Power requirements
The Sheep Auto Drafter is powered by an external 230V to 12V DC adaptor. This
comes as part of the package when you buy the Sheep Auto Drafter and can be
connected to your AC power supply (input range 100 - 240V AC).
You can also run the Sheep Auto Drafter off a 12V DC battery e.g. a car battery,
where there is no conventional power supply.
If you have a scale indicator or a RFID reader attached to the Sheep Auto Drafter
they will need to be powered separately (by their own batteries) as no power
supply runs to them from the unit.

3E2374 Sheep Auto Drafter User Manual
Page 11
Note: If you are wanting to read EIDs then make sure you keep the power supply
1m, or more, away from the unit side panels to avoid interference with the RFID
reader antennae.
Compressed air requirements
Once the compressor is connected and running you will be able to see what the
pressure is at the unit by looking at the pressure gauge attached to the Control
Bridge (see Figure 4). It should read between 4-6bar (in the green zone). Ensure
it does not enter the red zone (>6bar). A reading above 6bar indicates a regulator
issue, which would need investigation. Readings below 4bar are likely to be
caused by an air supply (compressor) problem. A typical compressor would be a
2HP 24 litre tank single phase machine.
Figure 4. ressure gauge (on the Control Bridge).
Scales and RFID reader requirements
The Sheep Auto Drafter has been specifically designed to operate with the
Gallagher SmartTSi, SmartScale 00, Weigh Scale 10 and Weigh Scale 610
scales. (Please note: Drafting by list is not available on the Weigh Scale 610
scale.) It will also operate with some other brands of weighing indicators - your
dealer will know which are compatible.
RFID (radio frequency identification) antennae are installed in each of the unit
side panels. A SmartReader BR or R unit is needed to communicate with the
antennae.
The antennae will recognise EID which are either HDX (half duplex) or FDX (full
duplex), and those which are inserted as implants or boluses (however these are
less commonly used).

Recommendations for the construction and use of
surrounding yards and races
(adapted from "Behavioral Principles of Livestock Handling" by Temple Grandin)
Race construction leading up to the Sheep Auto Drafter
Sides
Sheep have a wide visual field. The width is affected by the amount of wool they
have on their head and ranges from 191 to 306 degrees. Any handling races,
including the race leading up to the Sheep Auto Drafter, should have solid side
walls to prevent animals from seeing distractions outside the race. Any moving
objects, (e.g. people, flapping objects or a coat hung on a race fence) seen
through the sides of a race can cause balking or frighten sheep. Solid side walls
are especially important if animals are unaccustomed to the facility.
Layout
Curved single file races are recommended for moving sheep up to the Sheep
Auto Drafter. A curved race is more efficient for two reasons. Firstly, it prevents
the animal from seeing what is at the other end of the race until it is almost
there. Secondly, it takes advantage of the natural tendency of sheep to circle
around a handler moving along the inner radius of the race.
Width
Ideally the race will be designed in a way that organises sheep into single file by
the time they reach the junction with the Sheep Auto Drafter. This helps to
ensure that only one sheep enters the Sheep Auto Drafter at a time and makes
stock flow smoother. As sheep can be of varying sizes, (e.g. adult sheep and
lambs), it is useful to have a race with adjustable sides in the final lead up (the
last 1 0cm). However if the race width is fixed, approximately 50 cm is the
recommended width. This is the same dimension as the internal edge of the
Sheep Auto Drafter entry gate surround.
Materials
The materials the surrounding races are made of have the potential to affect the
reliability of the RFID reader. Metal components are best avoided if possible,
particularly if they rub together, as this can cause interference in the signal
between the reader and the EID.
Vision and lighting
Where the Sheep Auto Drafter is positioned illumination should be uniform and
diffuse, much like a bright cloudy day. Shadows and bright spots should be
minimised.
Sheep have a tendency to move from dim areas to brighter areas, provided the
light is not glaring in their eyes. Situate the Sheep Auto Drafter to take advantage
of natural light. Skylights, combined with other natural lighting, can even out

3E2374 Sheep Auto Drafter User Manual
Page 13
light levels so consider installing translucent polycarbonate roofing and or walls if
the area is dark.
Noise
In facilities where livestock are handled, loud or novel noises should be avoided
because they distress livestock. The sound of metal clashing together can cause
balking and agitation. As the Sheep Auto Drafter is constructed of composite
materials its operation is very quiet but the noise level in the surrounding yards
should be considered. The compressor providing air for the Sheep Auto Drafter is
best located at a distance to reduce noise levels. Rubber stops on gates in the
yards around the Sheep Auto Drafter will help reduce noise.
The effects of pain or fright
Research indicates that sheep can remember a painful or frightening experience
for many months. Sheep which had been inverted in a sheep handling machine
were more difficult to move through the machine the following year1. The fact
that the Sheep Auto Drafter has been designed with the comfort and safety of
stock in mind will help to ensure animals' experience of them is positive. This will
aid in the smooth entry and flow of stock through the system on future
occasions.
It is also worthwhile keeping in mind that livestock which have had gentle
handling in the past will be less stressed when they are handled in the future.
Think about how your actions will affect your future interactions with stock and
the efficiency of the operations you wish to carry out.
Moving the Sheep Auto Drafter
As the Sheep Auto Drafter is very light (~100 kg), due to its construction from
composite materials, it can be lifted manually by two people.
Note: Make sure you have the side panels attached when you shift the Sheep
Auto Drafter and that they are on the inside slot. Also, close the gates at either
end.
Transport poles can be purchased from your local Gallagher distributor which
can be inserted into slots provided in the gate surrounds (see Figure 5). Once the
poles have been inserted the Sheep Auto Drafter can be lifted and repositioned
(see Figure 6).
Warning! The drafter should be lifted when moved, not dragged. Dragging the
Sheep Auto Drafter will risk damage to the load cells housed within each foot.

Alternatively the Sheep Auto Drafter can be lifted mechanically, (e.g. by forklift),
by inserting forks or strops under the floor, or by attaching strops to the four
corners of the transport poles (nearest the end supports) and then lifting from
overhead with a forklift or loader.
Note: It is VERY IMPORTANT not to lift the Sheep Auto Drafter by the Control
Bridge as this action may damage it!

ASSEMBLING THE SHEEP AUTO
DRAFTER AND SORTING UNIT
Assembling the Sheep Auto Drafter
The Sheep Auto Drafter should be assembled when you purchase it. All you will
need to do is attach the following:
•air supply
•power supply
•scale indicator (if using)
•RFID reader (if using)
•sorting unit(s) (if using)
Attaching the scales indicator and FID reader
To find out how to do this see How to turn the Sheep Auto Drafter on (p 2 ).
Assembling the sorting unit
After you purchase the sorting unit you will need to assemble it. The following
instructions explain how to do this.
Figure 7. Drafting unit components
Tools required
•3/ in socket
•13mm socket
•17mm combination spanner

3E2374 Sheep Auto Drafter User Manual
Page 16
Method
1. The sorting unit will be assembled upside down, so place the roof upside
down on the ground.
2. Attach the two tie bars to the rear of the roof and screw them on with two
Tek screws (14 gauge x 50mm). There is a left and right hand side, the inside
edge will be stepped in (see photo below).
Tool required: 3/ in socket.
3. Attach doors by inserting shafts in holes in the roof. The left and right doors
are different so make sure the bolt to attach the air cylinders is on the

3E2374 Sheep Auto Drafter User Manual
Page 17
inside. The door pivot tubes should be inserted with the white bolt guide
into the roof.
4. Attach the floor by inserting the door pivot tubes and tie bars into the holes
in the floor (the back and front tubes are different sizes - those at the
drafting gate end are smaller, so make sure you have the floor around the
right way). Keeping the floor level as you push it on will make the job easier.
5. Drop the 4 through bolts into each corner of the floor and tighten (do not
over tighten).
Tool required: 13mm socket.

3E2374 Sheep Auto Drafter User Manual
Page 1
6. Fasten the two air cylinders to the doors by attaching lock nuts and washers
(m10 nut, 10mm flat washer) to the end of each one.
Tool required: 17mm combination spanner.
To find out how to attach the sorter to the Auto Drafter see Connecting the
sorting unit to the Sheep Auto Drafter (p 20), under "Using the Sorting Unit"
on page 35 later in this manual.
Adding an extra sorting unit
An extra sorting unit can be attached to the first, end to end using 2 zinc plated
hex bolts (M6 x 75mm long) and flat washers (6mm x 22mm long).
Note: When weighing animals it is very important that there is nothing touching
the Sheep Auto Drafter as this may affect its accuracy. Take care that the sorter
is attached correctly and any lead up races are not touching the Auto Drafter.

3E2374 Sheep Auto Drafter User Manual
Page 19
USING THE SORTING UNIT
The sorting unit allows you to automatically separate animals into groups by:
•weight, using weight limits set up in the scale indicator;
•reading EIDs and using drafting lists set up in the scale indicator.
Alternatively you can control the sorting unit manually with the remote control.
If you purchase one sorting unit, then animals can be divided into three different
groups, however you do have the option of linking an extra sorting unit. This will
give you the ability to draft in up to five different directions.
Like the Sheep Auto Drafter, the sorting unit is constructed primarily from
composite materials and has pneumatically operated gates, which means it is
light, safe to use and very quiet.
How the sorting unit works
You can run the sorting unit automatically, which is probably how you will use it
most of the time, or you can run it manually using the remote control. You
cannot use it independently from the Sheep Auto Drafter as the Sheep Auto
Drafter electronics control the sorting unit operation.
Automatic use
If the sorting unit is working automatically its operation is controlled by the scale
indicator, which sends signals through the Sheep Auto Drafter electronics to the
sorting unit. You will need to set up weight limits or a drafting list (using EIDs) in
the scale indicator to direct the sorting unit. To find out how to do this, refer to
your scales user manual.
If you have attached an extra sorting unit then you will need to run it
automatically as the remote control can only be used to operate one sorting unit.
Manual use
If the sorting unit is under manual control, the commands from the remote are
transmitted through the Sheep Auto Drafter electronics to the sorting unit. You
will need to use the remote to make each drafting decision.
For more detailed scenarios covering particular uses of the sorting unit in
combination with the Sheep Auto Drafter see Using the Sheep Auto Drafter (p
32).

Connecting the sorting unit to the Sheep Auto Drafter
Method
1. Sit the sorting unit about 150mm away from the Sheep Auto Drafter and
insert the air lines through the conduit at the top of the sorting unit.
Figure 8. Inserting air lines.
2. Slot the sorting unit onto the spigots protruding upwards from the Sheep
Auto Drafter foot. Screw them together with Tek screws (14 gauge 75mm).
Tool required: 3/ in socket.
Figure 9. Attaching to Sheep Auto Drafter.
3. Attach the male and female connections on the end of the air lines to their
mates inside the roof of the sorting unit. Check the air lines are not sagging
as they may get caught when the doors operate.
