11. OPERATING INSTRUCTIONS 

-

 DISCHARGE

 

11.1 Gearbox Speed Selection

 

IMPORTANT.   

The  machine  is  fitted  with  a  2

-

speed 

gearbox.    For  blockage  free  operation  it  is  important  that 
the  correct  gearbox  speed  is  selected  for  the  material 
being discharged as shown in Table 4.  The gearbox has a 
neutral  position  between  high  and  low,  so  make  sure  the 
required  gear  has  been  properly  selected  so  as  not  to 
block the rotor housing.

 

Table 4.  Recommended Rotor Speed

 

NOTE. 

  Dual  Chop  machines  cannot  chop  silage  or 

materials with high moisture content.

 

For  shredding  straw  and  other  dry  materials  either  rotor 
speed  may  be  used,  for  maximum  throw  distance  high 
speed  should  be  selected  on  the  rotor  gear  box  with  the 
handle moved towards the position marked by the hare to 
give a 1:1 ratio between PTO and discharge rotor speeds.

 

For  shredding  silage  and  other  wet  materials  it  is 
recommended  that  low  rotor  speed  be  used  since  long 
throw  distances  are  not  usually  required.  To  select  low 
rotor  speed,  the  gearbox  handle  should  be  moved  to  the 
position marked by the tortoise to give a 1.85:1 ratio.  The 
machine  may  be  used  at  reduced  PTO  speeds  and  still 
deliver  material  to  the  desired  position.  Low  PTO  speeds 
should  be  used  with  caution  as  a  blockage  in  the  rotor 
housing may result.  Do not operate with a PTO speed less 
than 300 rpm.

 

11.2 Right Hand Chute

 

Adjust  the  position  of  the  chute  to  deliver  material  to  the 
desired  location,  typically  this  will  be  down  beside  the 
machine for feeding and elevated for bedding. 

 

11.3 Sloping Swivel Chute

 

The swivel chute rotates through 280 degrees and can be 
operated to either side of, and behind the machine. 

 

To deliver silage close to the machine, position the chute 
so that material is delivered onto the feed passage slide.  
The  position  of  the  slide  can  be  adjusted  to  deliver  the 
material  accurately.    Alternatively  the  position  of  the  
material  can  be  controlled  by  the  chute,  it  may  be 
necessary  to  rotate  the  chute  fully  delivering  material 
alongside the drawbar. 

 

IMPORTANT.   

The  discharge  of  baled  silage  along  the 

left hand side of the machine is not recommended.

 

In transport, rotate the chute to the right hand side of the 
machine  aligning  the  indicators  on  the  chute  and  top 
housing.  Fully  lower the  deflector to keep  the  width  and 
height of the machine to a minimum.

 

11.4 Dual Chop Operation

 

NOTE. 

  Dual  Chop  machines  cannot  chop  silage  or 

materials with a high moisture content.

 

The Tomahawk 8555 with removable screen can be used 
to  dispense  clamp  silage  and  distribute  baled  silage 
without  chopping.    This  can  be  achieved  with  the  blade 
beam raised, screen removed and replaced with a screen 
blanking frame which prevents a build up of material in the 
screen support frame.

 

The sliding blade carrier is controlled through the hydraulic 
spool  valve.    An  indicator  attached  to  the  blade  beam 
shows  the  engaged  /  disengaged  positions  of  the  sliding 
blade carrier.

 

When a long chop length is desired, raise the blade carrier 
thus disengaging the blades.

 

When a fine chop length is desired, lower the blade carrier 
fully

 

to engage the blades against the crossbeater and put 

the  gearbox  in  low  discharge  speed.    Before  lowering  the 
blade carrier, stop the  bed  chain  and  wait for the material 
to stop flowing into the rotor.

 

Do not use intermediate positions as damage may occur.

 

11.5 Tomahawk 8555 Screen Change 

 

DANGER. 

Never  attempt  to  change  the  screen 

unless  the    PTO  has  been  disengaged,  the  engine 

has been stopped with the key removed from the ignition, 
and the machine has come to rest.

 

To  change  screen,  release  the  anti  luce  pins  from  the 
right  hand  side  of  the  machine  and  withdraw  the  screen 
from the machine.   Before fitting  the replacement screen 
check the lower guide groove of  the support frame is free 
from material using the blockage removal tool.  Access to 
the  frame  on  the  left  hand  side  of  the  machine  is  inside 
the chain guard.  Displace the cover to gain access.

 

An  optional  screen  storage  frame  is  available  where  the 
screen is changed regularly.

 

11.6 Starting The Machine 

 

Switch  the  control  desk  on.    Engage  the  hydraulic  spool 
valve  on  the  tractor  making  sure  the  bed  chain  has  not 
been started.

 

Position  the  selected  chute  and  deflector  to  give  the 
desired spread direction.

 

Engage the PTO with the tractor engine at idle speed and 
increase  the  speed  rapidly  to  working  speed  (540rpm) 
when the tractor clutch has engaged fully.

 

It  is  important  to  ensure  that  the  rotor  is  turning  at  full 
working speed before engaging the bed chain.   Failure  to 
do so is likely to result in a blockage.

 

 

11.7 Before Commencing Discharge

 

If the machine is loaded to capacity with bales, the tailgate 
must  remain  horizontal  until  the  material  in  the  body  has 
been discharged. This is necessary to allow material within 
the body of the machine to rotate freely once it comes into 
contact  with  the  crossbeater(s).    No  attempt  should  ever 
be made to force material towards the crossbeater(s) using 
the tailgate.

 

With  the  bed  chain  speed  dial  on  the  control  desk  set  to 
zero,  switch  the  bed  chain  on  in  the  forward  direction  by 
pressing  the  bed  chain  forward  button  once.    General 
discharging  instructions  follow  after  the  specific  round/
square bale and clamp silage instructions below.
