HEADER ATTACHING & DETACHING
DETACHING HEADER FROM COMBINE AND ADAPTER
Using this procedure, adapter will remain attached to
the combine. Instructions for detaching both header
and adapter from combine are given on page 15.
1. Choose a level area. Lower the reel and raise
the header so that cutterbar is about 18” off the
ground. Stop engine and remove key.
DANGER: To avoid bodily injury from
fall of raised header, engage header
lift cylinder stops when working on or
around raised header. See your
Combine Operator's Manual for
details.
DANGER: Wait for all movement to
stop. A rotating driveline can cause
entanglement resulting in serious
personal injury or death.
2. Disconnect driveline from feeder house shaft.
Detach chain at (A), remove pin (C) and store
this end of driveline on header frame tube by
securing or supporting at hydraulic/electrical
bracket. Ensure storage location does not
interfere with backing adapter out of header.
Reinstall pin (C).
3. Disconnect hydraulic lines:
• Reel lift between header and combine.
• Reel drive pressure and reel return between
header and combine.
• Draper return (blue) and draper drive
pressure (orange) between adapter and
header.
• Reel fore-aft / Header Tilt hoses between
header and combine (if equipped).
NOTE: Some combines are equipped with
multi-link couplers that connect several
hydraulic and electrical circuits at once.
IMPORTANT: Couple or cap all lines to prevent
hydraulic system contamination except as noted
in Warning below. Be sure header stored hoses
and combine stored hoses are not entangled.
WARNING: For headers with hydraulic
reel fore-aft, never connect the fore-aft
couplers to each other. This would
complete the circuit and allow the reel
to creep forward in transport, resulting in
instability.
4. Disconnect wiring harness between header and
combine. Cap harnesses to prevent moisture
from entering plugs.
5. Remove clevis pin from adapter float and move
handle up to “float lockout” position. Install pin in
hole (E) for 963/973/974 Headers, and hole (F)
for 972 Header. Install clevis pin and lynch pin.
Repeat at other side.
6. Remove clevis pin (B) from adapter lock
position. Repeat at other leg. Place pins in
storage hole higher up on leg.
