NOTE
For special conditions, 20T, 22T, and 26T
sprockets are available to change
adapter feed auger speed. Consult your
dealer.
The following functions are adjusted through
the adapter and are described in the following
sections:
• Header Float
• Header Leveling
• Header Draper Speed
• Header Sickle Speed
• Feed
Draper
• Auger
Refer to the D50 and D60 Harvest
Header/FD70 FlexDraper Operator’s Manual for
the following adapter/header operating
procedures:
• Header Angle
• Cutting Height
7.3.5 HEADER FLOAT
The machine will perform best with minimum
extra weight on the header. Under normal
conditions, approximately 75 lbf (337 N) force is
required to lift the header at the diagonal brace.
See Section 7.3.5.2 Checking Header Float.
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.
When float setting is light, it may be
necessary to use a slower ground speed
to avoid excessive bouncing and leaving
a ragged cut.
IMPORTANT
The stabilizer wheels may be used in
conjunction with main float to minimize
bouncing at the header ends and control
cut height. Refer to the D50 and D60
Harvest Header / FD70 FlexDraper
Operator’s Manual for details.
7.3.5.1 Float Locks
The header main float locks, lock and unlock
the header float system.
The main float locks must be engaged when the
header is being transported with the adapter
attached so there is no relative movement
between the adapter and header during
transport. The float locks must also be locked
during detachment from the combine to allow
the feeder house to release the adapter. There
are two locks, one on each side of the adapter.
