Revision A
Locking/Unlocking Header Float
Two header float locks
—
one on each side of the float module
—
lock and unlock the header float system.
IMPORTANT:
The float locks must be engaged when the header is being transported with the float module attached so there is no
relative movement between the float module and the header. The float locks also must be locked when detaching the float
module from the combine to enable the feeder house to release the float module.

in Locked Position
To disengage (unlock) the float locks, pull float lock handle (A)
into position (B). In this position, the header is unlocked, and
can float with respect to the float module.
To engage (lock) the float locks, push float lock handle (A) into
position (C). In this position, the header cannot move with
respect to the float module.
3.9.4 Header Angle
Header angle is adjustable to accommodate different crop conditions and/or soil types and can be adjusted using the
center-link between the combine and the header.
Refer to Adjusting Header Angle from Combine, page 133 for combine-specific adjustment details.

Figure 3.139: Header Angle
Header angle (A) is the angle between the header and the
ground.
The header angle controls distance (B) between the cutterbar
knife and the ground and is critical when cutting crop at
ground level.
Adjusting the header angle pivots the header at the point of
skid shoe/ground contact (C).
Guard angle (D) is the angle between the upper surface of the
cutterbar guards and the ground.
