LOADING ROUND BALES
To load round bales drive the machine forwards
forcing the front lip under the bale. Place the chains
around the rear of the bale. Cut the strings / netwrap on
the bale as low as possible on the machine side of the
bale. Raise the machine rolling the bale into the bale
chamber before removing the strings / netwrap
completely.
SPREADING MATERIAL/PERFORMANCE
With power connected to the Telehawk, switch the
control desk ON (making sure the bed chain dial is set to
’0’). Start the sequence:
1. Engage the spool valve on the loader.
2. Wait for the discharge rotor to rotate at working
speed.
3. Rotate the chute and adjust the deflector to give the
desired spread direction and distance.
4. Start the bed chain and cross beater by pressing the
bed chain spreading button. Spreading will now
start. Once the straw has cleared, increase the bed
speed to the desired level.
It is important to ensure that the fan motor is turning at
full working speed before engaging the bed chain.
Failure to do so is likely to result in a blockage.
With a rectangular bale in the chamber make sure that
the bed chain is lying horizontal. This allows the first
section of bale to rotate freely within the bale chamber.
See figure 1 for rectangular bales.
Figure 1. Spreading rectangular bales.
To maximise performance for square bales, keep the
machine horizontal. The speed of the bed chain will vary
on the quality of the bale. For brittle wheat bales a
higher speed of 6 to 8 can be achieved. For longer
damp material a slower speed of 3 to 5 is
recommended.
With a round bale in the chamber make sure that the
bed chain is inclined at 5
°
. See figure 2 for round bales.
To maximise performance for round bales, keep the
machine slightly angled upwards and keep the bed
speed on a setting of approx. 5. This will keep the round
bale tumbling. Stripping a thin layer of straw from the
bale with each rotation.
Once you have spread all the straw on the bed chain,
we recommend stopping the crossbeater before
increasing the angle of the Telehawk to allow the straw
to fall onto the bed chain. Once the straw has fallen onto
the bed chain, the machine can be levelled out and the
crossbeater and bed chain re
-
started.
If spreading wet or poor quality bales it may be an
advantage to stop both the cross beater and bed chain
before inclining the machine.
Do not force bales against the cross beater by inclining
the body steeply while spreading. This may cause a
blockage and could also damage the machine.
If you are moving from one shed to another. We suggest
stopping the bed chain by turning the speed to zero and
then stopping the crossbeater. Before starting again,
make sure the fan is running at normal speed then
re
-
engage the crossbeater. The bed chain speed can
then be increased.
The length of material will vary with the condition of the
bale. Fresh clean straw will tend to result in a longer
material where
-
as old, slightly damp, weathered or
matted bales will tend to have a shorter length. The
power consumption will also vary with the material being
spread. In general damp or matted straw will require a
relatively high power input.
In the cross beater hydraulic circuit, the Telehawk has a
sensor that monitors the oil pressure. When the
pressure becomes too high, the sensor switches the bed
chain and cross beater into unloading to prevent the
machine from blocking. This is called the unload time.
The bed chain and cross beater then automatically
restart spreading.
The length of unload time can be varied in the cab.
Generally, the taller the bale in the chamber the longer
the unload movement of the bed chain is required. The
unload time can be increased by pressing the increasing
unloading time button and decreased using the
decreasing button.

The pressure at which the bed chain unload movement
is triggered can be varied by rotating the knob on the
outside of the rotor housing. We recommend a starting
setting of 100bar. The higher oil flow rate the higher the
pressure setting. With a higher flowing loader the fan is
rotating at a higher speed, hence the fan can spread
more straw. With a lower oil flowing loader the fan is
rotating slower, hence can be more easily blocked. To
avoid this the pressure switch needs to be set lower (
