HEADER ATTACHING & DETACHING
DETACHING HEADER FROM COMBINE AND ADAPTER
(continued)
NOTE: Steps 7 is for 963 Headers only.
For 972/973/974 headers, go to step 8.
7. For 963 headers with gauge wheels, remove
pins at gauge wheels and place in stand
position (B). Block both gauge wheels.
For 963 headers without gauge wheels, lower
header stands (F) to the engaged position at
both outer legs. In dry conditions, cutterbar
and header stands do not require blocking. On
soft ground only, place 2x4’s (40 mm blocks)
under cutterbar, about 18" (450 mm) from
each end of header, and under the header
stands. Also in soft ground conditions, an 8 ft.
length of 2x4 laid in direction of travel under
the feed pan and cutterbar will prevent
scooping dirt when reattaching.
8. For 972/973/974 Headers, lower header stand
(E). In dry conditions, cutterbar and header
stand do not require blocking. On soft ground
only, place 2x4’s (40 mm blocks) under
cutterbar, about 18" (450 mm) from each end
of header, and under the header stand. Also in
soft ground conditions, an 8 ft. length of 2x4
laid in direction of travel under the feed pan
and cutterbar will prevent scooping dirt when
reattaching.
All Header Models:
9. Disengage header lift cylinder stops and lower
header to ground. Continue lowering adapter
until top link is loose. Detach top link (G).
NOTE: For headers with hydraulic top link,
cylinder stays with header and is attached and
detached at the adapter end.
10. Lower adapter until adapter legs are clear of
header legs and slowly back away from
header.
