attached to the windrower, ensure that the float
engagement pin is installed in storage position (B) and NOT
in engaged position (A).
DANGER
Ensure that all bystanders have cleared the area.

If the center-link is too low, it may contact the header as
the windrower approaches the header for hookup.
