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. Refer to your windrower operator
’
s manual for instructions on changing
ground speed.
CAUTION
Reduce speed when turning, crossing slopes, or traveling over rough ground.
In tough cutting conditions (such as native grasses), set the disc speed to MAXIMUM.
In light crops, reduce the disc header
’
s disc speed while maintaining ground speed.
NOTE:
Operating the disc 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 3.55: Ground Speed for R216 SP Rotary Disc Headers
A - Acres/Hour
B - Hectares/Hour
C - Kilometers/Hour
D - Miles/Hour
Example:
At ground speed of 21 km/h (13 mph) the area cut would be approximately 25 acres (12 hectares) per hour.
