OPERATION
HEADER ANGLE
Header angle is adjustable by changing the length
of the center link between header and adapter.
See header Operator’s Manual for header angle
adjustment ranges.
IMPORTANT: A flatter header angle is recom-
mended for normal conditions. A flatter angle
reduces sickle section breakage and reduces soil
build-up at the cutterbar in wet conditions.
A steeper header angle is recommended when
using a hay conditioner, when cutting very close to
the ground, or for better lifting action of down
crops.
NOTE: Center link is shown mounted in lower of
two positions. Use the top mounting holes only for
970 Series Headers without hay conditioner. Use
lower hole for all other Header/Attachment
combinations. If top hole is used for 970 Series
Headers with hay conditioner, damage to
conditioner shield and pump may occur.
To adjust header angle:
1. Unlock collar (C) by tapping it in a counter-
clockwise direction.
2. Using a long punch in hole (D), turn the center
link until the desired header angle is reached.
Shortening the link will give a flatter header
angle, while lengthening the link provides
steeper angles.
3. Lock collar (C) against link body by tapping in a
clockwise direction to secure the position.
Headers with 721/742 Hay Conditioner
(910/920 Series Auger Headers)
To provide proper clearance between hay
conditioner forming shields and pump on tractor
PTO, shield height must be adjusted to suit header
angle.
Mount shields in top hole (A) for flat header angle
and bottom hole, as shown, for steep header
angle.
To compensate for small changes in header angle;
shield position with respect to hay conditioner can
be adjusted by repositioning hardware in slot (B).
