Basic Combine Adjustments Chart

IMPORTANT: This chart indicates initial values. Different terrain and crop conditions may need subsequent adjustments.

Adjustments of chaffer extension are not indicated, it is recommended to adjust the extension 2mm more open than the chaffer or according to the amount of tailings.

Before adjusting combine to desired crop, consult distances between concave and threshing cylinder in "Adjusting Concave-to-Cylinder Clearance" in "Service" section.

NOTE: Always adjust cylinder speed with engine at top speed.
