Tines

Tine Wear

After the BlueBird Aerator has been used for 
sometime, the tines will wear. When this happens 
aerating performance diminishes. Inspect tines using 
the drawing, replace when at minimum length or 
before. (Tines are 5" when new.)

Unlock collar (best accomplished by using a 

14. 

hammer and pin punch). Insert pin punch into the 
hole next to the set screw and, using the hammer 
and with moderate striking, hit collar so that it 
rotates in the opposite direction the rotor would 
normally turn.
Reverse steps to reinstall.

15. 

Refer to sections “Chain Removal and 

16. 

Replacement” and “Adjusting Chain Tension” 
for chain replacement and adjustment of chain 
tension.
