HEADER
FLOTATION
IMPORTANT: To avoid frequent breakage of sickle components, scooping
soil,
or soil build-up at
cutterbar
in
wet conditions, header float
should
be
set
as
light
as
possible without causing excessive
bouncing.
Under normal conditions, adjust float spring tension so 50 to 70
Ibs.
force (220 to 300 N) is required to
lift cutterbar
off
ground at each end.
See "Header Flotation"
in
Windrower or Combine Adapter Operator's Manual for adjustment details.
HEADER
ANGLE
The
header (or guard) angle can
be
set between
go
and 13
0
below horizontal on the windrower.
The
header
(or
guard) angle can be set between 13
0
and 16
0
below horizontal on the combine. (Actual
range
may
vary
with
combine
set-up.)
IMPORTANT:
The flattest header angles are recommended for normal conditions. A flatter header
angle reduces sickle section breakage and reduces soil scooping or build·up
at
the cutterbar
in
wet
conditions. Use a steeper angle to
cut
very close to the ground, or
in
down crop for better lifting action.
See 'Windrowing" for the effects
of
header angle on windrow formation. See "Header Angle" in
Windrower
or
Combine Adapter Operator's Manual for adjustment details.
For
headers with gauge wheels, see -Gauge Wheel Field Positions" in this section for proper
relationship between gauge wheel setting and header angle.
DRAPER
SPEED
Draper speed affects the orientation
of
stalks in the delivered crop. See 'Windrowing" for the affect
of
draper speed on windrow formation. See Windrower
or
Combine Adapter Operator's Manual for
adjustment details.
DELIVERY
OPENING
WIDTH
For
windrower, the width and position
of
the delivery opening affects the width and configuration
of
the
windrow.
See
'Windrowing" for more information.
See Combine Adapter
Operators
Manual for recommended ovenap
of
side drapers over feeder draper.
The
center delivery opening can be adjusted to any width between 35- (890 mm) and 66- (1676 mm)
measured between the rollers.
NOTE: End delivery opening size is limited by windrower drive tires and/or deck contacting header
frame. When shifting decks to end delivery, ensure center delivery opening size
is:
21' Header - 42" (1067 mm) or narrower.
25' Header - 61" (1549 mm) or narrower.
30' Triple Delivery
Header·
54.5" (1384 mm) or narrower.
30' Double Delivery Header - 61" (1549 mm) or narrower.
36' Header - 61" (1549 mm)
or
narrower.
