Adjusting the Safety Door
On each side of the center deck is a safety door that opens
and closes as the wing decks are lowered and raised
(Fig. 68). The doors open to provide overlap of the cutting
blades when the wing units are down. The doors close to
provide safety and protection when the wing units are
raised. Check to make sure the forward, lower edge of door
(Fig. 68) is even or 1/4 in. (6 mm) higher then lower edge
of door guide when wing decks are in the fully raised,
transport position. If an adjustment to the door is required,
proceed as follows:

deck section so it cannot fall accidentally. Wing decks
must be horizontal to center cutting unit.
2. Rotate a center and adjoining wing blade so there blade
tips are aligned. Measure distance between blade tips,
distance should be approximately 0.25 ± 0.12 in.
(6 ± 3 mm) (Fig. 69).
