HEADER ATTACHING & DETACHING
DETACHING HEADER AND ADAPTER FROM COMBINE
Using this procedure, adapter will remain
attached to the header. This would be
appropriate when detaching header for transport.
Instructions for detaching header only from
adapter and combine are given on page 13.
1. Choose a level area. Lower the reel and raise
the header so that cutterbar is 18” off 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.
2. Remove clevis pin from adapter float and
move handle up to “float lockout” position (E). Lift
handle as high as possible, then lower until holes
line up. Install clevis pin and lynch pin. Repeat at
other side. Note that pin (B) locking adapter to header
remains in place.
IMPORTANT: Float is not locked out unless handle
is raised as high as possible. Actual pin position will
vary with header settings.
3. Disconnect hydraulic lines between header and
combine:
- Reel drive pressure line.
- Reel drive return line.
- Reel lift line.
- Reel fore-aft / Header tilt lines (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.
DANGER: Wait for all movement to stop before
approaching driveline. A rotating driveline can
cause entanglement resulting in serious
personal injury or death.
5. Disconnect driveline from combine feeder house output
shaft and store at hook (A) on adapter frame. Secure with
pin (C). This is especially important when transporting
headers in upright position on trailers.
6. Disconnect pump from combine feeder house output
shaft and store on adapter.
CAUTION: Pump maybe hot. Wear gloves when handling pump.
7. Raise header all the way up and engage cylinder lift stops.
8. Disengage the feeder house/header lock system. See Mounting Instruction for your make of combine at back of
book.
9. Disengage header lift cylinder stops on combine, start engine and lower header to ground.
10. Slowly back combine away from header.
