Levelling The Header - MacDon M105 Operator's Manual

Adjusting Float Using Drawbolts
Float adjustment uses drawbolts to change the tension on the springs in the lift linkages.
If necessary, adjust the float with the drawbolts as follows:
CAUTION
Check to be sure all bystanders have cleared the area.
1. Start engine.
2. Using HEADER UP (A) switch on ground speed
lever (GSL), raise the header fully, shut down engine,
and remove key.
3. Turn drawbolt (A) clockwise to increase float (makes
header lighter) or counterclockwise to decrease float
(makes header heavier).
4. Recheck the header float as described in
Float, page 120.

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
Stop engine and remove key from ignition before leaving operator's seat for any reason. A child or even a
pet could engage an idling machine.
