Install Mid-Wing Drags
If this is a model FH6600 harrow, there are no mid-wing
drags. Continue at “Install Wing Outside Drags” on
page 27.
Refer to Figure 29 and Figure 21 on page 21
80. Identify the drags to use on the inside of each wing.
If any of these drags has a side chain ( in
Figure 21 on page 21), place it so that the chain is to
wing outside (or inside if the inside drag did not have
a chain).
81. Lay two of this size drag out flat either side of the
wing inside drags.
82. Back the implement up to the drags. Raise the arms
up. Leave the wings unfolded.
83. Remove fasteners from free ends of leading
chains :
802-722C HHCS 9/16-12X3 1/2 GR5 ZNYCR
803-319C NUT HEX TOP LOCK 9/16-12 ZNYCR
Refer to Figure 30
84. 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 until bolt does not rotate freely.
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.
Refer to Figure 31
85. Lower the arms.
86. Remove fasteners from free ends of trailing
chains :
802-024C HHCS 3/8-16X3 GR5
803-013C NUT LOCK 3/8-16 PLT
Secure free ends of chains to arm with bolts
and lock nuts . Tighten nuts only to Grade 2
torque specification.
