4.4.5 Adjusting H eader Angle
Header angle is defined as the angle between the ground and the drapers/cutterbar and is adjustable to
accommodate crop conditions and/or soil type.
Refer to the appropriate header operator ’s manual for the range of adjustment and recommended settings for your
particular header.
The header angle can be hydraulically adjusted from the cab without shutting down the windrower. A readout on the
cab display module (CDM) allows you to establish settings for each crop condition. This feature requires that the
optional expansion module MD #B4666 be installed, either at the factory or at your MacDon Dealer.
