Locking/Unlocking Header Wings
The FD75 FlexDraper

is designed to operate with the cutterbar on the ground. The three sections move
independently to follow the ground contours. In this mode, each wing is unlocked and is free to move up and down.

can also be operated as a rigid header with the cutterbar straight. A typical application is in
cereals when cutting above the ground. In this mode, the wing is locked.

1. Move spring handle (A) in the lower slot to unlock the
wing. The unlocking should be audible.
