OPERATION
HEADER ANGLE
Header (or guard) angle can be varied from 6° to 11.5° below horizontal. Choose an angle that maximises
performance for your crop and field conditions. A flatter angle provides better clearance in stony conditions
while a steeper angle is required in down crops for better lifting action.
To adjust header angle:
a. Loosen nut (A).
b. To decrease (flatten) header angle, turn nut (B) clockwise.
c. To increase (steepen) header angle, turn nut (B) counter-clockwise.
d. Tighten nut (A) to 200 ft.lbs. (270 N.m)
After adjusting header angle:
a. Check cutting height and adjust if required. See "Cutting Height" in this section.
b. Check header float and adjust if required. See "Header Flotation" in this section.
NOTE: Two optional kits are available which allow
header angle to be adjusted hydraulically with a
cylinder replacing the mechanical link shown
above. One kit (B 4257) requires a separate
hydraulic circuit from the tractor. The other
(B 4256) uses the existing tongue steering cylinder
hydraulic circuit, and a remote switch-operated
selector valve controls which circuit is currently
active. Installation instructions are included with
the kits.
