4.4.3 Levelling the Header
The windrower linkages are factory-set to provide the proper level for the header and should not normally
require adjustment.
DANGER
To avoid bodily injury or death from 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 is not level, check the windrower tire pressures before adjusting the levelling linkages.
