6.1 – Corn Head Angle

Danger: Before repairing or adjusting any part of the corn head, engage the feeder house lift
cylinder safety stops, set the parking brake, turn off the combine engine and remove the key
and hang a warning sign on the operator’s platform. Failure to do so could result in serious
injury or death.

Important: It is critical that the angle of the corn head is adjusted to run between 17° and 23° for
non-chopping corn heads and 21° to 23° for corn heads equipped with stalk choppers. Failure to do so
may cause damage to chopping gearboxes (if equipped).

6.1.1 – Corn Head Angle Adjustment

1) Ensure the tire pressures and ballast are correct for the corn head being used. See the Combine
Operators Manual for specific information on configuration.
2) Move the combine to a flat, level surface.
3) Completely attach the corn head to the combine (See Section 3.1)
4) Lower the corn head until the head is at operating height.
5) Measure angle of the deck plates by placing an angle finder (ST-6), included in the black document box
on the back of the corn head, directly on the deck plates.
a. Non-chopping corn heads
i. Head angle should be between 17° and 23°.
ii. Recommended setting for normal harvest conditions is 20°.
iii. Recommended setting for down corn is 22-23°.
b. Chopping corn heads
i. Head angle should be between 21° and 23°.
ii. Recommended setting for normal harvest conditions is 21°.
iii. Recommended setting for down corn is 22-23°.
6) If the corn head is not at the correct angle, disconnect the corn head (See Section 3.2) and adjust the
head angle by one of the two options below.
a. Course Adjustment: Performed by loosening the bolts of the corn head adapter frame and moving
it to one of the three locations.
b. Fine Adjustment: Performed by adjusting the angle of the feeder house faceplate on the combine.
See Combine Operators Manual for the correct adjusting procedure.
7) Reconnect the corn head and recheck the head angle.
8) If the corn head angle is not correct, repeat step 6.
9) If the head angle is correct, adjust the snout tips until they are touching the ground. See Section 6.2.2.
