5.9 Leveling Header
The windrower lift linkages are factory-set to provide the proper header level and should not normally require adjustment.
DANGER
To prevent bodily injury or death from the unexpected startup of the machine, always stop the engine and remove the
key from the ignition before leaving the operator’s seat for any reason.
If the header level needs to be adjusted, follow these steps:
1. Remove the float spring tension to ensure that the lift windrower linkages are not affected by the float springs. For
instructions, refer to 5.6.3 Removing and Restoring Float – M2 Series Windrowers, page 104.
DANGER
Ensure that all bystanders have cleared the area.
2. Start the engine.
