required to raise the center-link (B) so that the hook is
above the attachment pin on the header.

the windrower approaches the header for hookup.

on the windrower enter the boots (B) on the header.
Continue to drive slowly forward until the feet engage
the boots and the header nudges forward.
5. Activate HEADER TILT cylinder switches on ground
speed lever (GSL) to extend or retract center-link
cylinder so that the hook lines up with the header
attachment pin.
