6.17.16 Ground Speed
CAUTION
Reduce speed when turning, crossing
slopes, or when travelling over
rough ground.
a. Tractor/windrower 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.
b. Choose a ground speed that allows the knife to
cut the crop smoothly and evenly.
c. 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
16 FT header, the area cut would be approximately
10 acres (4 hectares) per hour.
