3.0  SAFETY 

 

In addition to the standard safety guidelines  listed  at 

the  beginning  of  this  handbook,  the  following  special 

safety items apply to the  Tomahawk. 

 

3.1 

WARNING.  

Never

 

put  your  hands  inside 

the  delivery  chutes.    In  the  event  of  a 

blockage, clear it using the tool provided (stored 

across  the  top  of  the  rotor    bearing  housing).  

First,    stop  the  engine,  remove  the  key, 

disengage  the  PTO  and  wait  for  the  rotor  to 

come to rest.

 

3.2 

WARNING.  

Never  enter  the  drum  unless 

the  machine  is  resting  on  the  ground,  the 

engine  stopped,  the  key  removed,  the  PTO 

disengaged and the rotor come to rest. 

3.3 

WARNING.

  Never  attempt  to  connect/

disconnect  flexible  duct  connections  with 

the PTO operating or the booster fan turning.

 

3.4 

WARNING.  

Never  insert  anything  inside 

the  flaps,  booster  fan  housing,  outlet 

chutes,  flexible  ducting  or  drum  whilst  the 

machine is running.

 

3.5 

WARNING.

 Do not allow anyone to ride on 

the machine or tractor linkage.

 

3.6 

WARNING. 

Do  not  allow  persons  or 

animals to stand in front of the outlet chutes 

whilst the machine is running.

 

3.7 

CAUTION.  

Always  ensure  good  rearward 

visibility when reversing.

 

3.8 

WARNING.  

Never  put  your  hand  over  a 

hydraulic leak.  Oil  under  pressure  may 

enter the blood stream.

 

3.9 

CAUTION. 

Exercise 

caution 

after 

prolonged  use  of  a  Tomahawk  equipped 

with  a  booster  fan  as  the  oil  temperature  will 

have  risen  causing  hydraulic  fittings  and  hoses 

to be hot.

 

3.10 

CAUTION.   

The  shredding  of  dusty  or 

mouldy  material  can  cause  dust  having 

adverse  health  effects.    Operator  exposure  to 

such  conditions  should  be  avoided  where 

possible.  When circumstances  prevent 

this, 

either use a tractor with a suitable forced air cab 

filtration  system  or  use  an  adequate  respirator.  

Respirators must comply  with 

the 

relevant 

Standard  and  be  approved  by  the  Safety 

Inspectorate.    Disposable  filtering  face  piece 

respirators to EN149 or half mask respirators to 

EN140 fitted with filters to EN 143 are likely to be 

adequate.

 

3.11 

NOTE.   

If a hydraulic top link is used, ensure that 

the top of the Tomahawk is clear of the cab with 

the  machine  fully  raised  and  the  top  link  in  the 

fully contracted position. 

 

3.12 

NOTE.   

When  lifting  the  machine  on  the  three 

point  linkage,  always  check  the  clearance 

between  the  upper  front  of  the  Tomahawk  and 

the rear of the cab, particularly the window if it is 

open, as the machine is lifted. 

 

3.13 

CAUTION.   

Care  must  be  taken  when 

handling large bales, as they have sufficient 

weight  and  density  to  cause  serious  injury.  

Large bales should  be handled  with appropriate 

machinery  and  loaded  directly  into  the 

Tomahawk  drum.    Do  not  manually  load  bales 

from  a  stack  above  the  machine,  so  as  to 

prevent the risks of falling into the machine and 

collapse of the stack of bales. 

 

3.14   

NOTE.   

If the machine is to be lifted by means 

other  than  the  standard  3  point  linkage  then  it 

should  be  lifted  using  the  loop  provided  on  the 

top of the machine.  When lifting the machine it 

will  hang  with  the  drum  horizontal.    Upon 

lowering the rear of the frame will touch the floor 

first  and  the  machine  will  tilt  forwards  until  the 

front foot of the frame touches the floor. 

 

4.0  LEFT AND RIGHT HAND  

 

In  this  handbook  and  parts  list,  the  terms  Right  and 

Left Hand apply  to  the machine  when  viewed looking 

towards the rear of the tractor.  
 

5.0  USE OF THE TOMAHAWK 

 

Tomahawk  404M  and  505M  hammer  mill  models  are 

designed  to  chop  round  bales  of  dry  straw  and  hay 

only.    Tomahawk  4040  and  5050  silage  models  are 

designed to chop round bales of straw, hay, silage and 

roots.    Tomahawks  fitted  with  the  booster  fan  kit  are 

designed to chop dry materials only. 
 

Optional chutes available are: 

Low  level  chute  on  the  left  hand  side,  suitable 

 

only for dry materials (standard on 404 / M and 

 

505 / M models). 

Giraffe  high  level  straw  chute,  suitable  only  for 

 

dry materials. 

Giraffe  high  level  silage  chute,  (only  available 

on  4040  and  5050  models)  suitable  for  all 

materials the machine is designed to handle. 

 

The various delivery options are shown in Figs. 1 - 3.
