Checking and Adjusting Header Wing Balance
Header wing float is the ability of the header’s wings to react to changing ground conditions. If set too LIGHT, the
wings will bounce on the ground. If set too HEAVY, the wings will dig into the ground. The wings need to be balanced
for the float system to work properly.
CAUTION
To avoid personal injury, before servicing machine or opening drive covers, refer to

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:
