Adjustment of Cylinder and Concave

1. High cylinder speed
+ narrow concave spacing
__________________
= Good threshing action

Extreme adjustment:
Cylinder speed too high
+ concave spacing too narrow
__________________
= Overthreshing


2. Low cylinder speed
+ wide concave spacing
__________________
= Poor threshing action

Extreme adjustment:
Cylinder speed too low
+ concave spacing too wide
__________________
= Underthreshing


3. Basic Adjustment

· Moist crop: Increase cylinder speed and/or reduce concave spacing.

· Dry crop: Reduce cylinder speed and/or increase concave spacing.


IMPORTANT: Cylinder speed and concave adjustments are the most important factors in obtaining good harvesting results.
