Revision D
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.
Change auger drive sprockets, as follows:
CAUTION

before leaving Operator's seat for any

b. Remove snap-ring (C) from pulley (D), and
remove pulley.
