spinning. 

  Check that all guards are properly fitted and there are no damaged or loose 

parts. Particular attention should be given to the blades to ensure they are not 
damaged, cracked or missing

  Ensure tractor guards are fitted correctly and are undamaged 

  Work  at  a  safe  speed,  taking  into  account  terrain,  passing  vehicles  and 

obstacles

machine manufacturer and that ballast is used if necessary 

  Check that machine fittings and couplings are in good condition 

 

Follow the manufacturer’s instructions for attachment and removal of machine 
from the tractor 

  Ensure  blades  are  of  the  type  recommended  by  the  manufacturer,  are 

securely fitted and are undamaged 

  Ensure  hydraulic  pipes  are  correctly  routed  to  avoid  damage  from  chafing, 

stretching, pinching or kinking. 

  Check condition of tyres and tightness of wheel nuts. 

  Ensure  all  blades  have  stopped  spinning  before  folding  wings  into  transport
