4.12 Checking and Adjusting Header Wing Balance
NOTE:
Before proceeding, the header float must be set properly. Refer to 4.11 Checking and Adjusting Header Float, page
105.
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.
4.12.1 Checking Wing Balance
This procedure describes how to check the balance of each wing.
WARNING
To avoid bodily injury or death from unexpected startup of machine, always stop engine and remove key
before making adjustments to machine.
Figure 4.39: Wing Imbalance
If a wing has a tendency to be in a smile (A) or frown (B)
position, wing balance may require adjusting. Perform the
following steps to verify if the wings are not balanced and
the degree of imbalance:
Figure 4.40: Center-Link
1. Adjust the header center-link to approximately halfway
between B and C on indicator (A).
2. Park combine on level ground and raise header until
cutterbar is 152–254 mm (6–10 in.) off the ground.
3. Stop engine and remove key.
4. If installed, move transport/stabilizer wheels so that
they are supported by header. Refer to instructions
provided with the transport/stabilizer system.
