HEADER OPERATION
Operating Variables
END DELIVERY: The left deck of the 962 header
can be manually shifted to close off the center
opening and deliver crop to the left end of the
header. This provides the capability of windrowing
with a combine or non-windrower tractor as the
power unit.
To shift left deck:
1. Reverse draper travel by disconnecting hydraulic
hoses at (B) and connect to opposite lines.
2. Remove deck retainer clips at cutterbar, item (G)
on previous page. (If front edge draper seals are
installed at cutterbar, remove these seals and
clips as well.)
3. For Model 872 Adapters, turn needle valve
control (D) on adapter valve fully open to stop
hydraulic flow to the feed draper and drum. Valve
must be fully open to prevent rotation of feed
draper and drum when oil is cold.
4. Lower the header to the ground and continue until
adapter lowers.
5. Lengthen center link between header and adapter
to steepest header angle to increase clearance to
header back sheet
6. Loosen bolts (C) at both clamps on left deck.
Attach a "Come-Along" from a sickle guard to the
deck cross member (A) as shown. Move deck to
the right until 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.
NOTE: If there is interference between deck
backsheet and combine adapter upper feed
device (auger or retracting tine drum) move
auger/drum back to provide clearance. See Drum
Fore-Aft Adjustment in 872 Adapter Manual.
7. Tighten bolts (C) at both clamps.
8. Readjust center link to achieve desired header
operating angle.
9. Reinstall deck retainer clips (and front edge
draper seals, if required).
10. With header and combine feed chain drum
floated up, check clearances: There should be 1
to 2 inches (25 to 50 mm) clearance between
adapter drum and combine feed chain drum,
while still providing adequate clearance to header
backsheet. If repositioning adapter drum does not
provide enough clearance both fore and aft,
remove one row of tines from drum (2 or 3 tines,
depending on drum size).
11. Adjust header flotation to compensate for the shift
in weight. See "Header Flotation" in Windrower
or Combine Adapter Operator’s Manual.
12. For rotary combines with narrow feeder opening,
increase delivery opening width to be suitable for
windrowing. See "Delivery Opening Width",
beginning on page 20.
