1. Roll correct size disc gang assembly under frame
and wing assembly. See Table 3-4 for disc size and

cap screws, and hex lock nuts (See Figure 3-9.)

screws, and hex lock nuts.
IMPORTANT
The distance between last blade on main frame and
first blade on wing should be 7-1/2".
IMPORTANT
Disc rod and slotted nut should be tightened to a
torque of 1200 ft. lb. This is equivalent to a 200 lb.

toward the middle of the machine and carry soil back
to center of the main frame. The bracket clamp is
installed between adjustment bracket and bottom of
