Install 4-Row Drag Extensions
This step is only required if the extensions were ordered
as Option 20, and were not factory pre-attached to the
12-row drags. See Install Wing Extensions in “Operator’s
Manual for details.
Connect Linking Chains
Refer to Figure 35
The trailing (bar 12 or bar 16) tubes of each wing with
more than one drag (which always includes the center
wing), are linked together with short chains
provided.
Chains may already be installed on one side of some
connections. On 16 bar implements, chains may need to
be moved from bar 12 to bar 16.
94. Each linking requires one:
564-092D CHAIN 5/16 HIGH TEST 8 LINKS

803-342C NUT HEX TOP LOCK 1/2-13 PLT
891-238C HARROW TOOTH - 8 1/2" DIAMOND

one end, twist the chain

turn to align the end link
with the tube hole.
97. Reinstall the tooth . Tighten nut only to Grade 2
torque specification, to avoid crushing tube.

Do NOT link drag sections from wing to wing. The chains
are not long enough to accommodate the distance required for
wing folding.
