12.  Lug Timing

For Standing Corn:  

Time the gathering chain lugs so the lugs are staggered.

For Down Corn:  

With 9-tooth idlers, time the lugs so they are almost horizontally opposed 

from each other. Adding plastic paddles will also help in harvesting down corn. (See page 16)  

These oversized down corn plastic gathering chain paddles are available for 
purchase from Calmer Corn Heads.

13.  Reinstall bolt and washer into top of gathering shaft to secure 7-tooth sprocket.

14.  Tighten the gathering chain tightener until there is a 3/16” clearance  
       and washer.  Apply anti-seize or lubricant to threads for future adjustments. 

15.  Test for proper installation of components. To ensure proper installation of components, using   
       the feeder house reverser, operate corn head for 10 seconds. Next, operate corn head  
       normally at idle then gradually increase to full speed.
