SAFETY INFORMATION    

There  are  obvious  and  hidden  potential  hazards  involved  in  the  operation  of  this 
implement. Serious injury or death may occur unless care is taken to insure the safety of 
both the operator and any other persons in the area. KEEP CLEAR AT ALL TIMES 
The  following  is  a  list  of  some  safeguards  which  should  be  followed.  Serious  injury  or 
death may occur unless care is taken. 
 

 

Where  this  is  used  as  a  rear-mounted  implement  it  will  remove  weight  from  the  front 

wheels  –  this  can  result  in  less of  steerage and  risk of  overturn.  Add front end  weight  to 
ensure 20% of tractor original weight is on the front wheels when the boom is in transport 
position. This will aid steering safety reducing the risk of bodily injury. 
 

 

Always  transport  slowly  on  rough  surface  to  prevent  ‘bouncing’  of  the  front  wheels 

causing loss of steerage and possible injury. 
 

 

Always  set  tractor  wheel  width  as  wide  as  possible  and  add  weights  to  the  relevant 

opposite wheel to counteract the weight of an extended implement. 
 

 

Operate the machine only with a tractor equipped with an approved roll-over-protection 

system  (ROPS).  Always  wear  approved  seat  belts  whenever  the  tractor  or  machine  is 
running.  Serious  injury  or  death  could  result  from  falling  off  the  tractor  seat.  Do  not  alter 
the ROPS structure. 
 

 

Always  ensure  that  check  chains/stabilizers  are  fitted  and  are  in  good  condition  and 

tight. 
 

 

The  operator  and  all  support  personnel  should  wear  ‘Safety  Shoes’,  ‘Hard  Hats’,  and 

‘Safety Glasses’ at all times to protect them against falling objects. 
 

 

Never  allow  inexperienced  or  untrained  personnel  to  operate  the  tractor/cutterbar 

combination without training or supervision. 
 

 

Always  familiarise  yourself  with  the  controls  in  a  clear  safe  area  before  commencing 

work. 
 

 

Always familiarise yourself with the local highway regulations and abide by them at all 

times. 
 

 

The  boom  and  cutterhead  change  the  balance  of  the  machine  in  transport.  Be 

especially careful when transporting on slopes. Never turn uphill in transport except at very 
slow  speed  and  a  low  rate  of  turn.  Never  transport  or  operate  this  machine  on  steep 
slopes. BE CAREFUL. 
 

 

Always  inspect  the  work  area  or  hedgerow  for  wire,  steel  posts,  or  other  dangerous 

materials and remove them if possible before commencing work.
