3.7.4 Checking and Adjusting Header Wing Balance
IMPORTANT:
Before proceeding, the header float must be set properly. Refer to Checking and Adjusting Header Float, page 64.
The header wing balance allows the wings to react to changing ground conditions. If set too light, the wings will
bounce or not follow ground contours, leaving uncut crop. If set too heavy, the end of the header will dig into the
ground. After the header float has been set, the wings must be balanced for the header to follow the ground
contours properly.
Checking Wing Balance
This procedure describes how to check the balance of each wing.
IMPORTANT:
To ensure correct wing balance readings, make sure the header float is set properly before proceeding. Refer to
Checking and Adjusting Header Float, page 64.
WARNING
To avoid bodily injury or death from unexpected startup of machine, always stop engine and remove key
before making adjustments to machine.
Figure 3.53: Wing Imbalance
If a header wing has a tendency to be in a smile (A) or a
frown (B) position, wing balance may require adjusting.
Perform the following steps to check if the wings are not
balanced, and how much adjustment is required.
The header wings are balanced when it takes an equal
amount of force to move a wing up or down.
