Tine 

Replacing a tine 

A tine must be replaced if it is broken. Open the tine mounting bolt and remove  
the old tine. Leave the bolt in the tine clamp and insert the new tine into the clamp.  
Pull the tine backwards so that the bolt contacts the tine axle. Tighten the nut to  
110 Nm. Retighten the mounting bolt of the tine point after the first day of operation. 

Replacing a tine point 

Tine points can be reversed and attached with the old bolt and nut if this is done 
before the bolt head becomes excessively worn. Always replace the bolts and nuts 
when replacing the tine points with new ones. 

Never hold the bolt head with your hands when turning  
the tine point nut.
