HEADER OPERATION
Operating Variables (continued)
CUTTING HEIGHT
Cutting height will vary, depending on whether
windrowing or straight-cutting, type of crop, etc.
See "Windrowing" for stubble height recommen-
dations.
Gauge Wheel Field Positions:
For headers equipped with gauge wheels or the
gauge wheel/transport package, choose Field
Position 1 or 2 to maintain proper gauge wheel
spring force at desired cutting height.
Field Position 1 when cutterbar is above the
ground (4 to 12 in. [100 to 300 mm] cutting height.
Field Position 2 when cutterbar is on the ground
(0 to 4 in. [100 mm] cutting height).
NOTE: When changing gauge wheel field position,
readjust header flotation. See "Header Flotation" in
Windrower Tractor or Combine Adapter Operator's
Manual.
NOTE: Gauge wheel field position should also be
related to Header Angle. Use Position 2 for flatter
header angles and Position 1 for steeper header
angles.
