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 (
