Mainframe Locks: ROAD to FIELD
Refer to Figure 20
10. Pull the wire handle outward and move to rear slot.
This allows a hook (not shown) to move forward and
allow the center section openers to lower.

Wing End Locks: ROAD to FIELD
Refer to Figure 21 (shown tilted down for clarity - perform this
lock change while the openers are tilted up)
11. Reverse the catching direction of the wing end locks.
Pull the wire handle outward. Rotate the pin 180
degrees, placing the angled surface forward and the
longer side of the tip to the rear. This allows the plate
to push the pin aside during tilt-down, and catches
the plate for down-pressure regulation in the field.
Unfolding: Tilt-Down
The transport hook and transport locks must be released
(step 4 through step 9 starting on page 26) before per-
forming the next steps.
Tilt-Down After Unhook and Before Unfold
For smoothest operation, and to reduce risk of machine dam-
age, perform the tilt-down after transport unhook and before
unfold.
Refer to Figure 22
12. On the CFM switch, enable Tilt with MASTER and
Tilt on.
