OPERATION
WINDROWING WITH THE COMBINE
When laying a windrow, stop flow to the feed
draper and drum as follows:
• Remove hose (A) at pump (inboard port).
• Remove hose (B) at hydraulic line.
• Connect hose (B) (removed at hydraulic
line) to open port at pump using connector
hose listed below.
• Connect hose (A) (removed at pump) to
hydraulic line using male union listed below.
NOTE: The following parts will be required to
make the new connections: Part No. 33422

Feed Pan Ground Clearance Adjustment
for Windrowing – 972/973/974 Headers
Spacer plate (F) is factory assembled for best
ground clearance, with plate (F) mounted to the
forward set of holes in pan (G) as shown above
left. When windrowing with the combine and in
certain other conditions, clearances may be such
that the header drapers catch on the deck or on
side deflectors. If so, move spacer plate (F) to rear
set of holes in pan (G) as shown above right. To
reposition spacer plate (F):
• Remove two center bolts (K) and loosen bolts
at outside ends of pan.
• Slide spacer out (forward) and slide it in from
the back onto the loosened bolts.
• Replace the two center bolts, exchanging
positions so the 1-1/4” bolt again goes through
the spacer plate.
• Exchange positions of the bolts at outside ends
of pan so the 1-1/4” bolts go through spacer
plate.
