2. Intrroduction
Tanco Autowrap Ltd congratulates you on your choice of the TANCO AUTOWRAP 1320 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 bale wrapping machine has more features than any other bale wrapping machine
available. The 1320 can pick up the bale, wrap and stack them without the operator leaving the tractor
cab; this is a patented system.
This machine is hydraulically driven by the tractor’s hydraulic system and is controlled from the trac-
tor cab by an automatic control unit. TThe machine can either be mounted to three point linkage, front
mounted with quick-couplers to the tractors front loader or on a wheel loader. Then it’s possible to stack
the bales upon each other. The wrapped bale can be either dropped conventionally to the ground or with
the tting of an optional ‘End Tip’the bale can be dropped on its end.
TANCO AUTOWRAP 1320 is designed to wrap bales of grass, hay or straw, with nominal diameter of 1.1 -
1.5m, and weights up to (1200kg). The original 1300 model was launched in the mid 1980’s and has been
developed into the very reliable and safe machine we have today.
This manual is meant to explain how TANCO AUTOWRAP 1320 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 prob-
lem 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 1320 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 autow-
rap, 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 hilighted below some of the
dangers that can occur when using the 1320 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 earlier explained, we have a wrapping arm with a Dispenser and a plastic roll. During every revolution
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.
4. Safety Precautions

Tanco Autowrap - 1320

- Squeeze Danger Between the Staionary 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).
- 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).
- Squeeze Danger between the Rollers and the Main Frame
During the wrapping process the bale rotates on two rollers. When the rollers are in motion there is a
danger of being squeezed.
- Squeeze Danger between Roller Arms and Main Frame (Inwards)
When loading a new bale, the roller arms move towards the main frame, Beware of the danger.
Keep clear of this area.
- Squeeze Danger between Roller Arms and Main Frame (Outwards)
When loading or unloading a new bale, the roller arms move outwards. Beware of the danger.
Keep clear of this area.

Three Point Mounting
When the machine is mounted on the three point linkage, make sure that the lifting arms are tightened
up so there is no sideways movement.
Front Mounting
If the machine is mounted on a front loader there must be a counterweight tted to the three point link-
age. It must be large enough to give the tractor good stability.
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:
- Ensure the machine is in the transport position.
- Ensure the squeeze arm is fully closed.
- Enure that the wrapping arm is not parked overhanging the sides of the machine.
- Ensure that the lights are connected and functioning correctly
- 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.
- The machine is wide (2660mm) even in tranport 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.

Tanco Autowrap - 1320
Operator’s Manual
11
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 wrap-
ping, 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 rec-
ommended 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 recom-
mended. 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 driedout 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.

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.
Three Point Linkage
TANCO AUTOWRAP 1320 is intended for rear mounting
to the three point linkage, Category 2. When attached
to three point linkage, make sure the machine is level
across the tractor. Tighten up and lock the lifting arms so there is no sideways movement.
Top Link
Adjust the top link of the tractor so that the machine is level with the ground. It is recommended to use a
hydraulic top link, as this makes it easy to adjust the angle of the machine.
During the wrapping process it is recommended to tilt the machine towards the tractor, as this will pre-
vent the bale from falling o the rollers. (See Fig. 3).
You also need longer hydraulic hoses. (See spare parts list chapter 4-2 for more details).
When front-mounted there must be a large enough counterweight tted to the three point linkage, this
is to secure the tractors stability.

1320 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. En-
sure 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 1320 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 1320 is set-up for open
centre on leaving the factory.
Push & Twist to lock for Closed Centre
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 ma-
chine 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 that tractor is constantly pumping and you do not get the benet of the ef-
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 sig-
nal 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.
