SECTION 7. OPERATION
Reel speed affects feeding of crop into the sickle and onto the drapers, as well as the smoothness and evenness of the delivered crop.
Operating the reel too fast or too slow relative to ground speed will cause bunching.
At the proper speed, the reel discs should appear to be being driven by the ground.
• If they look like they are skidding relative to ground, the reel is turning too slow.
• If they look like they are spinning excessively relative to the ground, reel speed may be too fast.
In standing crop, reel speed should be just faster than or equal to ground speed, sweeping crop across the sickle.
Flattened crop or a crop that is leaning away from the cutterbar requires a higher reel speed in relation to ground speed. This can be achieved by increasing reel speed, decreasing ground speed, or both.
Excessive shattering of grain heads or crop loss over the header back tube may be indications that reel speed is too fast.
Excessive reel speed causes undue wear of reel components and unnecessary load on reel drive, resulting in uneven reel motion.
Generally, 9 bat reels can effectively operate at lower reel speed, while minimizing crop loss in shatter prone crops.
The reel speed is adjustable with the controls in the windrower cab. Refer to “Reel Speed” in your
Windrower Operator’s Manual for adjustment details.
