OPERATION
DELIVERY OPENING WIDTH : To adjust delivery opening width: 21', 25', 30' & 36' Headers
8. Position decks for desired opening width:
(continued)
Hydraulic Shift Headers
a) Adjust inboard stops:
• With decks in center delivery position, measure
distance from header leg to edge of idler roller.
Compare this value to the "X" value given in
chart on page 28 for the desired opening size.
• Move the inboard stops (G) (located between
header legs) the proper amount to achieve
chart value "X".
NOTE: It may be necessary to partially shift
deck in to allow proper positioning.
NOTE: Stops (G) may be removed to obtain
widest opening position.
b) Adjust outboard stops:
• Reposition outboard deck stops (H) after an
adjustment to delivery opening width, as
follows:
• Start engine and engage header clutch. Move
deck shift switch to shift one deck towards the
other. Disengage header clutch when there is
approximately 2 inches (50 mm) clearance
between the rollers of the two decks.
• IMPORTANT: This clearance is required to
prevent contact between draper connectors or
slats as they pass between decks.
• Stop engine. Remove bolts at outboard stop (H)
of the shifted deck and move the stop against
motor bracket (J). Replace bolts in deck stop.
• Start engine and engage header clutch. Move
deck shift switch to move decks back the other
way, again disengaging clutch when clearance
is about 2 inches (50 mm).
• Stop engine and position the other outboard
deck stop as above.
NOTE: An alternate method of setting the deck
stops is to shift decks to the center delivery
position, then measure the distance the deck
must travel to reach the 2 inch (50 mm)
clearance position. Set deck stop (H) the same
distance from the motor bracket (J).
9. Position backsheet extensions:
Row (A) - Windrower
Row (B) – Model 871 Combine Adapters*
Row (C) - End Delivery
(closes off center opening)

Combine Adapters with rubber side deflectors.
(Retain for end delivery use.) Extensions may also
be removed completely for windrowing in bulky
crops.
