Ground Speed - MacDon R85 Operator's Manual

6.8 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.
Refer to your MacDon self-propelled windrower operator's manual for changing ground speed.
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.
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.
Figure 6.20: Ground Speed
Example: At ground speed of 13 mph (21 km/h) the area cut would be approximately 25 acres (12 hectares)
per hour.
