Install Center Drags
61. Pick an area large enough to lay out all the drags,
as they will be arranged when installed. Allow
room to back the implement up to this area, and
once leading chains are attached, pull forward to
extend drags to full length.
Refer to Figure 22 and Figure 21 on page 21
62. Identify the drags to use on the center wing. These
are always two 6-foot sections:
564-043A6FT12ROWDRAG or
564-102A 6 FT 8 ROW DRAG
If one of this part-numbered drags has a side chain
(
in Figure 21 on page 21), place it so that the
chain is to wing center.
63. Lay the drag out flat.
64. Back the implement up to the drag. Raise the arms
up. Leave the wings unfolded.
65. Remove fasteners from free ends of leading
chains :

66. For the standard 40
° tooth angle secure each
chain to the lower holes in the mount (between
the plates), using bolts and lock nuts .
Tighten nuts only to Grade 2 torque specification.
For the alternate 22
° tooth angle, use the upper
holes. Using 22
° also requires chain relocation.
See Tooth Angle in “Operator’s Manual” for details.
