Revision A
Adjusting Cutterbar Angle
–
Optional Hydraulic Center-Link
Cutterbar angle is one of the settings that affects cutting height. On machines equipped with the optional hydraulic center-
link, you can adjust the cutterbar angle from the tractor cab.
To adjust the cutterbar angle on a machine equipped with a hydraulic center-link, follow these steps:
NOTE:
The cutterbar angle can be adjusted from the tractor without shutting down the header.
DANGER
Ensure that all bystanders have cleared the area.
1.
Start the engine.
2.
Lower the header fully.

3.
Decrease (flatten) the cutterbar angle by operating the
tractor hydraulic control so that cylinder (A) retracts
4.
Increase (steepen) the cutterbar angle by operating the
tractor hydraulic control so that cylinder (A) extends.

Ground Speed
Choose a ground speed that allows the cutterbar to cut the crop smoothly and evenly. Try different combinations of disc
speed and ground speed to suit your specific crop.
CAUTION
Reduce ground speed when turning, crossing slopes, or traveling over rough ground.
In tough cutting conditions, such as when cutting native grasses, set the disc speed to MAXIMUM.
In light crops, reduce the disc speed while maintaining the same ground speed.
NOTE:
Refer to your tractor operator
’
s manual for instructions on changing ground speed.
NOTE:
Operating the header at the minimum disc speed will extend the service life of the cutting components.
The example shown in Figure
illustrates the relationship between ground speed and cut area for R113 and
R116 rotary disc headers. The chart demonstrates that a ground speed of 21 km/h (13 mph) would produce a cut area of
approximately 8 hectares (20 acres) per hour.
