4.9 Ground Speed
CAUTION
Reduce speed when turning, crossing slopes, or when travelling over rough ground.
Choose a ground speed that allows the cutterbar and conditioner to cut the crop smoothly and evenly. Try different
combinations of header speed and ground speed to suit your specific crop.
In tough cutting conditions, such as native grasses, the disc speed will need to be increased.
In light crops, the header speed can be reduced while maintaining ground speed.
Refer to your windrower operator’s manual for changing ground speed.
NOTE:
Operating the header at the minimum disc speed will extend the wear life of cutting components.
The chart below indicates the relationship between ground speed and area cut.

Example: At ground speed of 21 km/h (13 mph) the area cut would be approximately 25 acres (12 hectares)
per hour.
