5000-026A ASSEMBLY INSTRUCTIONS 

(JD 608C, 708C, 843, & 893) 

 

 

 

Step 1:

 Attach the 5000-202 mount brackets to the frame using the 5/8 x 6 bolts, mounting straps, & 5/8” lock hex nuts. 

Mounting Brackets will be located under the snouts between rows 1 & 2, 2 & 3, 3 & 4, 5 & 6, 6 & 7, and 7 & 8. Slide the mount 
bracket up so the deck plate adjustment rod is located in the cut out of the mount bracket. On JD 893 corn heads, use the 
5000-301 L Clamp Plate with the mounting brackets between rows 1 & 2 and 7 & 8 If corn head is equipped with protective 
shield (like pic with the arrow shows), you can either: remove each shield, cut a notch in each shield, or bend each shield 
upwards to gain clearance. The shields on a 90 series head will need removed. 

Note:

 Do not fully tighten hardware until 

Step 6

 after all of the pivot arms & springs are installed.
