Adjusting Wing Balance
Wing balance ensures that the left and right wings require the same amount of pressure to follow the ground. The amount
of ground force/pressure required to lift the wings, and the speed that wings return to the ground when the pressure is
reduced should be equal/balanced.
DANGER
To prevent bodily injury or death from the unexpected startup of the machine, always stop the engine and remove the
key before adjusting the machine.
This procedure describes how to adjust the balance of each wing. Before proceeding, refer to Checking Wing Balance, page
69 .
IMPORTANT:
To ensure correct wing balance readings, make sure the header float is set properly before proceeding. For instructions,
refer to
Checking and Adjusting Header Float, page 60 . The float module must be sitting level before performing any
adjustments.
NOTE:
This procedure is shown on the left side; perform the steps to both sides of the header.
