Rotor Care

 

 

Always 

inspect the condition of flails and bolts on a very regular basis. 

 

Always 

replace bolts and nuts when replacing flails 

 

Always           

use genuine flails, bolts and nuts. The flails and bolts are made to a 

                       very high standard from a high tensile steel, being fully heat treated 
                       and subjected to rigorous testing in very stringent conditions to comply     
                       with our rigid quality control requirements 
 
 

Never            

operate with bolts loose or flails missing. 

 

Never            

change to a different spec or type of flail, this will immediately put the  

                      rotor out of balance. 
 

Never            

engage rotor at high PTO speeds. 

 
 

Remember, the rotor is highly complex and expensive to manufacture, please 
treat with care and enjoy the benefits of the Spearhead Rotor.

Warning 

 
                             

Rotor is balanced to be run at PTO speed, do not operate above or below 

                          this speed.

 

 

 

                         

Warning 

                            
                          Never carry out any servicing or maintenance work without first 
                         disengaging the PTO and stopping the tractor.
