9.11.3 Header Float
D50, D60, and FD70 combine headers perform
best with minimum extra weight on the header,
under normal conditions.
Check the float as follows:
9.11.3.1 Main Float Locks
The function of the header main float locks are to
lock and unlock the header float system.
There are two locks - one on each side of the
adapter.
IMPORTANT
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.
a. Disengage main float locks by moving latch (A)
away from adapter, and moving lever (B) at each
lock to “lowest position”. In this position, the
header is unlocked, and can float with respect to
the adapter.
b. Engage the main float locks by moving lever (B)
up to its “highest position”. In this position, the
header cannot move with respect to the adapter.
9.11.3.2 Checking and Adjusting Float
CAUTION
Stop engine, and remove key from ignition
before leaving Operator's seat for any reason.
A child or even a pet could engage an idling

a. If adjusting FD70 FlexDraper header main float,
ensure both wing float locks (C) are engaged.
Spring handle is in LOCK position.
