HEADER OPERATION - GENERAL
Form 169552 / 169554 / 169555
78
Revision A
f. If additional levelling is required, install the
removed shim on the opposite linkage.
g. Once header is level, return float pins to their
engaged position (F).
NOTE
If required, additional shims are available
from your MacDon Dealer
NOTE
Float does not require adjustment after
levelling header.
6.4.4 HEADER DRIVE
The headers are hydraulically driven and
controlled from the windrower with no
mechanical drive shafts.
One hydraulic piston pump on the windrower
provides fluid power to the knife, and three gear
pumps power the drapers or auger, reel, lift and
positioning systems and optional attachments.
CAUTION
Check to be sure all bystanders have cleared
the area.
Engage the header as follows:
a. Move throttle to adjust engine speed to idle.
b. Engage header by pushing down on the yellow
knob, and pulling up on the black ring at the
base of the switch.
c. A slight delay between switch ON and operating
speed is normal.
d. Push yellow knob to disengage header drive.
6.4.5 HEADER 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 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 CDM allows the
Operator to establish settings for each crop
condition. This feature requires that an optional
module has been installed, either at the factory
or at your MacDon Dealer.
IMPORTANT
Changing header angle will affect flotation
slightly because it has the effect of making
the header lighter or heavier.
IMPORTANT
To prevent excessive guard breakage
when conditions are not suited to heavier
float (e.g. rocky or wet), do not use the tilt
control “on the go”. Instead, use the
HEADER HEIGHT switch.
