Ground Speed - MacDon 912 Operator's Manual

GROUND SPEED

Ground speed of windrower should be such that
sickle can cut crop smoothly and cleanly.
See Windrower Tractor Operator's Manual for
identification and instructions for use of ground
speed control.
The chart below indicates the relationship between
ground speed and area cut for the three auger
header sizes.
Example shown: At a ground speed of 6 miles per
hour (9.7 km/h) with a 14 ft. header*, the area cut
per hour would be 10-1/2 to 11 acres (4-1/4 to
4-1/2 hectares).
* A 14 ft. header has a cut width of 14 ft. 3 in. (4.3 m)
A 12 ft. header has a cut width of 12 ft. 3 in. (3.7 m)
A 16 ft. header has a cut width of 16 ft. 3 in. (5.0 m)
An 18 ft header has a cut width of 18 ft. 3 in. (5.6 m)
