OPERATION
LEAN BAR POSITION
IMPORTANT: To prevent structural damage to the
header, do not operate with lean bar removed.
Use the lean bar adjustment to accommodate
different crop heights.
The lean bar should strike the upper portion of the
crop, leaning it away from the header and
exposing the stalks to the sickle.
To extend or retract lean bar, re-position hardware
(A) in adjustment holes as required.
GROUND SPEED
CAUTION: Reduce speed when turning, crossing slopes, or when traveling over rough
ground.
Tractor ground speed should not exceed 8 mph (13 km/h). For most crop conditions a ground speed of 5 mph
(8 km/h) has been found satisfactory.
Choose a ground speed that allows the sickle to cut the crop smoothly and evenly.
The chart below indicates the relationship between ground speed and area cut for three header sizes.
Example: At ground speed of 5 mph (8 km/h) with a 14 ft. windrower, the area cut would be approximately 9
acres (3.7 hectares) per hour.
