Torque the screws to 27–34 Nm (20–25 ft-lb.).
4.
Start the engine, raise the center cutting unit
slightly so that the rear deck straps can be mounted
on the lift arm brackets. Stop the engine after the
cutting unit is raised.
5.
Secure the rear deck straps to height-of-cut
brackets on the deck with hair pin cotters and
height-of-cut pins. Start the engine and lower the
center cutting unit completely to the floor. Assure
all lift levers are in the float position and stop the
engine.
6.
Connect the wire harness and (3) hydraulic lines
couplers at the rear of the deck.
Safety Door Adjustment
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 the door (Fig. 68) is even or 6mm higher
than the lower edge of the door guide when the wing
decks are in the fully raised, transport position. If an
adjustment to the door is required, proceed as follows:
1.
Loosen the jam nuts securing the ball joints to a
threaded rod.

Rotate the threaded rod to raise or lower the edge
of the door until it is even or 6mm higher than the
lower edge of the door guide when wing decks are
in the fully raised, transport position.
3.
Tighten the jams nuts to lock adjustment.
Blade Adjustment
To assure proper operation of the cutting unit, there must
be 6mm ±3mm clearance between the tips of the wing
and the center cutting unit blades.
1.
Raise the cutting unit so blades are visible and
block the center deck section so that it cannot fall
accidentally. The wing decks must be horizontal to
the center cutting unit.
2.
Rotate a center and adjoining wing blade so their
blade tips are aligned. Measure the distance
between blade tips. The distance should be
approximately 6mm ±3mm.
Figure 70
3.
To adjust distance, locate the adjuster bolt on the
rear outside corner of center cutting unit. Loosen
the jam nut on the adjuster bolt. Loosen or tighten
the adjuster bolts until a 6mm ±3mm clearance is
attained, then tighten the jam nut.
4.
Repeat the procedure on the opposite side of the
cutting deck.
Check for proper operation of the safety doors
each time the deck is cleaned and repair as
needed.
