6.17.3 Reel Speed 
For best feeding of the crop into the header/ 
mower conditioner, reel speed must be faster 
than ground speed. This gently sweeps material 
across the sickle into the auger. 
A slower reel speed will reduce crop carry-over, 
while a faster reel speed will result in a more 
even stubble height in down and tangled crops. 
6.17.3.1  Reel Speed: A30-S, A30-D 
The A30 reel speed is fixed to the engine rpm 
and auger speed. An optional 19 tooth drive 
sprocket provides lower reel speeds if 
necessary. 
Refer to Section 5 SPECIFICATIONS for 
available reel speeds at rated tractor/windrower 
RPM.
