the header.
IMPORTANT:
Ensure that the center-link is positioned high enough that it
does not contact the header as the windrower approaches
the header.
11. Drive the windrower slowly forward until feet (A) enter
supports (B). Continue to drive slowly forward until the feet
engage the supports and the header is nudged forward.
12. Ensure that feet (A) are properly engaged in supports (B).
13. Windrowers equipped with the self-aligning
center-link kit:
a. Adjust the position of center-link cylinder (A) with the
switches on the GSL until hook (B) is above the header
attachment pin.
IMPORTANT:
Hook release (C) must be down to enable the self-

b. If hook release (C) is open (in the up position), shut
down the engine, and remove the key from the
ignition. Manually push hook release (C) down after
the hook engages the header pin.
