2. Introduction
Tanco Autowrap Ltd congratulates you on your choice of the TANCO AUTOWRAP 1400 bale wrapping
machine. We are certain you will be satised with the machine, and that you will have the pleasure of your
investment for many years.
The TANCO AUTOWRAP 1400 is an ecient, high capacity bale wrapping machine. Its low centre of
gravity and unique split table design ensures that power consumption is kept to a minimum without
compromising output; this is a patented system.
This machine is hydraulically driven by the tractor’s hydraulic system and is controlled from the tractor
cab by an automatic control unit. The machine is trailed directly behind the tractor for transport and oset
to the right for working in the eld. It loads the bale on the wrapping table in the same direction as it is
discharged from the baler. The wrapped bale can be either dropped conventionally to the ground or with
the tting of an optional ‘End Tip Ramp’ the bale can be dropped on its end.
TANCO AUTOWRAP 1400 is designed to wrap bales of grass, hay or straw, with nominal diameter of
1.1 - 1.5m, and weights up to (1400kg). The machine was developed and has been improved since it’s
beginning in 2008, and is now a very reliable and safe machine with high security built in.
This manual is meant to explain how TANCO AUTOWRAP 1400 is setup, attached to tractor, used and how
it works, and shall together with the spare part's list be a reference for maintenance and troubleshooting.
So take good care of this book; it is a part of the machine.
Read carefully through this manual, and especially the safety instructions, before starting the machine.
Follow the instructions thoroughly, if problems should occur, check the troubleshooting guide to try
to establish the problem. Ask your dealer for advice before you attempt anything that may make the
problem worse.

4. Safety Precautions
Tanco Autowrap Ltd does not take responsibility for damages that may occur to machine, persons or
other equipment, because of the machine NOT being used as described in this manual, or because of the
safety precautions NOT being followed.
Emergency Stop
The Tanco Autowrap 1400 is equipped with a so-called emergency stop on the wrapping arm. This device
stops all functions momentarily, but is per denition not an emergency stop, because it does not shut
down the inputs. But it has the same function, so we have decided to call it an emergency stop in this
manual.
Safety Equipment
Before using the machine, make sure that all guards and covers are securely tted. The machine must not
be operated if a function does not work as described later in this manual.
Become Familiar with the Operations of the Machine
If you are unsure how to operate the machine properly, either use of or maintenance to your Tanco
Autowrap, please contact your Tanco Autowrap dealer.
Adjustments / Maintenance
Turn o the tractor and discharge the oil pressure before performing any adjustment or maintenance on
the machine. Remember that a well maintained machine is a safe machine.

IMPORTANT!
Always make sure nobody is in the hazard area of the wrapping arm when the machine is in-use.
The machine must not be operated by persons who do not know enough about how to safely operate
the machine, or by persons under the age of 16 years.
Dangerous Areas
Tanco Autowrap Ltd. has given the safety to the operator the highest priority, but it is still impossible to
secure oneself of every danger area on the machine. Therefore we have highlighted below some of the
dangers that can occur when using the 1400 Tanco Autowrap Bale Wrapper.
Impact of the Wrapping Arm
During the wrapping process the arm rotates with a speed of 30-35 revolutions per minute around the
bale. On the arm is mounted a Film dispenser unit with a plastic roll. The speed on this can give a per-
son serious injuries if one enters the working area of the wrapping arm. To reduce this danger we have
mounted an emergency stop device on the wrapping arm; this stops all movement when something
comes in the way of it. It is very important that this protection always works and that it should not
under any circumstances be disconnected.
Squeeze Danger Between the Main Frame & Wrapping Arm
As explained earlier, we have a wrapping arm with a Dispenser and a plastic roll. During every revolu-
tion the wrapping arm passes the main frame. Here there may occur a squeeze danger if a person
stands to close to the main frame when the wrapping arm passes. The distance between the main
frame and the wrapping arm is not large enough to give place for a person. Between the pre-stretcher
and the bottom frame there can also be a squeeze danger.

Fig. 2
Squeeze Danger Between the Stationary Arm & Wrapping Arm
During the main wrapping process the wrapping arm moves around a stationary arm. Every
time the wrapping arm passes the stationary arm there is a squeeze danger that can be
dangerous for the ngers. The distance between the stationary and the wrapping arm is
between 25-40 mm. (See Fig. 2).
Impact of Bale Squeeze Arm
During the bale loading process the bale squeeze arm moves both vertically and horizontally, beware of
the danger and keep clear of this area whilst the machine is running.
Impact Danger when Machine is being changed from Transport to Working Position at the Drawbar
When the machine is being changed from transport to the working position it rotates out to the right
and when it is being put back into transport it rotates back to the left, beware of the danger and keep
clear of this area whilst the machine is running; especially if the squeeze arm is in the open position.
Squeeze Danger Caused by Plastic Automation
At the end of the wrapping process the plastic is cut and held tight until the start of the next
wrapping process. When the cutter arm moves down to lock the plastic, there can occur a
squeeze danger between the cutter arm and the cutter holder. The cutter blade that cuts the
plastic is very sharp; ensure to keep hands away from the cutter. (See Fig.2).

4. Safety Precautions
Connecting heavy working implements often has an overall negative eect on the tractor’s driving
and braking capacity.
Transporting
When transporting on a public road there are certain safety measures that must be taken:
1. Ensure the machine is in the transport position.
2. Ensure the squeeze arm is fully closed.
3. Ensure that the wrapping arm is not parked overhanging the sides of the machine.
4. Ensure that the lights are connected and functioning correctly
5. It is recommended that the lm rolls be taken o the dispensers for road transport and put on
the lm carriers on the drawbar. This reduces stress on the machine and reduces the danger of the
rolls being accidently falling o on the public road.
6. The machine is wide (2660mm) even in transport position, be aware of this especially on narrow
roads.

5. Bale Wrapping
Bale Wrapping Principles
The advantages of round bale silage are many, and include fewer feed units, a exible harvesting system,
large capacity and the possibility of selling feed units.
In principle, the same fermentation processes occur whether the fodder is placed in a silo or pressed into
bales and packed in plastic, i.e. lactic acid fermentation in anaerobic conditions. The oxygen in the bale
must be exhausted before fermentation begins.
The grass should be dried to approximately 30-40% solid content. The solid content can be determined
by twisting the grass by hand. If drops of liquid are forced out of the grass, the solid content is less than
25%. Low solid content (wet grass) can lead to increased butyric acid fermentation if preservatives are
not added to the grass. If the solid content is too high, (over 50%), normal fermentation will not take
place and there will be enough oxygen in the bale to produce mould fungus.
The Baler
It is vital that the baler produces compact, well-formed bales, as misshapen bales can be dicult to wrap.
Wrapping will also often take longer, thereby increasing the amount of plastic used.
Dicult Bales
When a misshapen bale is wrapped, it will have a tendency to move outwards or inwards on the roller. If
the bale begins to move outwards, the machine must be lifted slightly at the rear edge to get the bale to
rest against the support roller on the main frame. It can therefore be useful to use a hydraulic top link to
make this adjustment easier. (See Chapter 5; ‘Hitch Height’).

Tanco Autowrap - 1400
Operator’s Manual

5. Bale Wrapping
If the bale to be wrapped is conical you must ensure that the sharp end is pointed at the tractor. It
will then be easier to get the bale to lie correctly during packing. It is easy for such a bale to “turn”
forward in the direction in which it is pointing, and therefore lie against the support rollers. If the
bale is lying on a slope it must be picked up from the lower side. A hydraulic top link will again be
advantageous.
Types of Plastic
A good type of plastic with good adhesive properties, and which is recommended for bale
wrapping, must be used. The thickness of the plastic foil should be at least 25 µ. (25/1,000 mm). In
order that the plastic tightens suciently around the bale, it is stretched before being wrapped,
so it is somewhat thinner when it is put on the bale. With short-term storage (up to eight weeks) it
is recommended that bales have a minimum of four layers of plastic at the thinnest points, with at
least 52-53% overlap.
For long-term storage, or when the grass is wet when it is wrapped, the bale should have 90-100 µ
plastic (six layers) and the same amount of overlap. If thinner plastic is used, more layers should be
applied. If it is very hot the plastic will be stretched further, and more layers should be applied. It is
better to have slightly too much than too little plastic on the bale.
From experience, light colored plastic produces slightly lower temperatures within the bale, and
tends to improve feed quality.

Storage Location
Care should be taken in nding a suitable location for the storage of bales. The storage location
should preferably be prepared before the bales are laid out. An elevation close to well-drained roads is
recommended. If the wrapped bales are simply placed on stubble there is a danger of the plastic being
pierced. A tarpaulin or a thin layer of sand should therefore be laid where the bales are to be stored over
the winter.
Bales should be stored in the shade as far as possible. This reduces the danger of air leakage in the bales.
A bale which is stored in sunlight and which therefore undergoes greater swings in temperature “pumps
in” a great deal of air in comparison to a bale stored in the shade. According to“Teknik for Lantbruket”
[Technology for Agriculture] in Sweden, a bale stored in the shade has only 40% of the air leakage of a
bale which is stored in sunlight.
Stacking / Protection
If bales are hard and well formed, they can be stacked vertically, but loose and misshapen bales with low
solid content should not be stacked higher than one layer, as this could easily cause deformity and the
danger of runo will be increased.
Bales can also be stored on their sides. The layer of plastic is thicker here, providing greater protection
against piercing.
Bales should be covered with a tarpaulin or a ne-mesh net to protect against birds and small rodents.
If the plastic is pierced, it must be sealed with weatherproof, hard-wearing tape, preferably under the
outermost layer of plastic. Ensure that the hole is adequately sealed.

For Best Wrapping Results...
1. Harvest the grass early.
2. Ensure the grass is dried out to 30-40% solid content. If there is a danger of rain, bale and wrap the
grass anyway.
3. Take care not to mix any earth in with the grass.
4. Use a baler that produces even, rm bales. Bales 1.2mtrs in width and with a diameter of 1.2-1.5mtrs are
preferred sizes.
5. Wrap the bales as soon after baling as possible; never more than two hours afterwards.
6. Use a good plastic type, applying six layers of plastic. This removes the need to use preservatives.
7. Store bales in the shade to reduce the danger of air leakage.

6. Machine Setup
Mounting of the Machine
Be careful! There is a danger of being crushed when working implements are tted and connected.
Carry out the tting procedures slowly and carefully, and use separate and approved lifting equipment
to make the work easier. Note the section on safety precautions and pay attention to the various safety
decals displayed on dierent parts of the bale wrapper.
Attaching to the Tractor
The 1400 can be either connected to the tractor lower links using Linkage Attachment or by removing
this it can be attached to the tractor hitch using the Hitch Eye.
If the lower link bracket is used the Hitch Eye should be attached in the lowest position; this will allow
greater movement.
If attached to the tractor hitch it is recommended that the machine is attached to the Clevis Hitch rather
than the Pick-Up Hitch. This gives more clearance between the Drawbar and the tractor’s back wheels.
The Drawbar does not run directly behind the tractor. In transport the Drawbar runs nearer the left wheel
so the minimum turning circle to the left is reduced. In the working position this is the case for turning
to the right. When the machine is attached to the tractor the Drawbar Leg must be folded up to the
Drawbar by removing the Drawbar Pin; swing the Drawbar Leg upwards and t the Drawbar Leg Pin to
Position B. (See Fig. 3 Overleaf).

When attached to the tractor the machine should sit level, at this the squeeze arm will have 10cm
approximate clearance with the ground when in the fully lowered position. Set linkage height to achieve
this.
Adjust the linkage stabilizers to limit the lateral movement.
If attached to the hitch change the hitch eye mounting position to set the correct height.
Ensure the Hitch Eye Fixing Bolts are securely tightened.

1400 Control Box
The control unit consists of the emergency stop button, a control cable, a
fuse and a battery cable. The control unit should be attached to a suitable
place in the tractor cab using the suction pad provided.
The Remote Control Unit is not Shock Proof, make sure that is fastened to a
soft pad that secures a non-vibratting foundation.
Electrical Connection
The electric supply for the machine’s remote control and electro-hydraulic
components must come directly from the tractors’12 volt battery.
The electric wires from the battery must have an area measurement of min.
2,5 mm2. Connection to other contacts on the tractor can cause risk of
malfunction and is not recommended.
Note:
Brown leader goes to the Battery’s Possitive Pole
Blue leader goes to the Battery’s Negative Pole

Hydraulic Connection
The hydraulic hoses between machine and tractor are equipped with 1/2”ISO Male Quick-Couplers.
Ensure the oil pressure has been discharged before you connect the oil hoses using the tractor’s
hydraulic lever.
To make sure that the bale wrapper works properly, the tractors’oil pressure has to be at least 180 bar.
The oil ow should be 15 - 25 liters per minute. The return pressure on the return must be as low as
possible, and not exceed 10 bar. This should be measured with a gauge. It is recommended to use one
single-working hydraulic outlet and arrange a free return circuit to the oil tank.
If you are unsure of what oil pressure the tractor gives, or what oil pressure the bale wrapper receives,
please contact your machinery dealer. Generally all tractors have got some counter-pressure in their
hydraulic return systems. Some tractors have more than others.
Note:
The Hose with the Red Cap shall be connected to pressure ‘P’ and Hose with Blue Cap to the return ‘T’.

Open & Closed Center Hydraulics
The 1400 hydraulic system can be set up for tractors with Open or Closed Center Hydraulics.
Open Centre Hydraulics
Most tractors have a hydraulic system that gives a continuous output which ows through the valve on the
machine and back to tank when no function is operating (Open center).
Note:
The TANCO AUTOWRAP 1400 is set-up for open centre on leaving the factory.
Close Centre Hydraulics
Some tractors (John Deere) have a hydraulic system that require the valve on the
machine to allow no ow when no function is operating (Closed Center).
The hydraulic valve can easily be congured to operate in this way.
Simply push and twist the Manual Override on the Master Valve. (See Fig. 4)

LS Hydraulics
Many modern tractors have a“Load Sensing”(LS) Hydraulic System. This is most ecient as the pump
remains on standby, pumping no oil until it gets a signal from the machine. It is possible to run this
machine on a load sensing tractor with the standard valve.
Congure the valve for open centers and if possible adjust the ow from the tractor to give ~30 lts/
min. This however means that the tractor is constantly pumping and you do not get the benet of the
eciency of your load-sensing pump.
Tanco Autowrap strongly recommend that if you are running the machine on tractor with LS Hydraulics
you t the optional Load-Sensing Block (see Hydraulic Circuit). With this block tted a Load sensing
signal is transmitted in the form of hydraulic pressure via a hose for the LS Port on the LS Entry Block to
the LS Connection on the tractor.
Note:
The LS Entry Block can be congured also to run on any other hydraulic system, open or closed center.
