262334 118 Revision A
3.12 Selecting Ground Speed
Choose a ground speed that allows the knife to cut the crop smoothly and evenly.
CAUTION
Reduce the speed when turning, crossing slopes, or when travelling over rough ground.
Windrower ground speed SHOULD NOT EXCEED 13 km/h (8 mph). For most crop conditions, a ground speed of 8 km/h
(5 mph) has been found satisfactory.
The chart below indicates the relationship between the ground speed and the area cut for three header sizes. For example,
at a ground speed of 8 km/h (5 mph) with a 4.9 m (16 ft.) header, the area cut would be approximately 4 hectares
(10 acres) per hour.

E – 5.5 m (18 ft.) F – 4.9 m (16 ft.) G – 4.3 m (14 ft.)
