OPERATION
3. On ground speed lever (GSL), press DISPLAY SELECTOR switch (E) until ##.# AUGER SPEED is displayed
at (A) or on cab display module (CDM), press FAST (C) or SLOW (D).
Display (A) shows ##.# AUGER SPEED
18 .
##.# = 4.7 to 9.9
4. Press FAST (C) or SLOW (D) on CDM until desired auger speed is displayed at (A).
NOTE: Changing the auger speed does not affect the reel speed.
4.7.2 Reel Speed
Refer to your header operator’s manual for recommended reel speed settings for your particular crop.
Reel Speed on A30-D Headers
The reel is driven by the auger, and both are dependent on the main header drive speed. The auger speed and
hence the reel speed can be changed by installing a different size auger drive sprocket, or by varying the windrower
engine rpm. These headers do NOT have a reel speed sensor, therefore no read out is available for the display.
Reel Speed on A40-D Headers
The A40-D Auger Header features a hydraulic direct drive reel with an operating speed range of 15–50 rpm
that is controlled with switches on the cab display module (CDM) and on the ground speed lever (GSL) at the
operator’s station.
The reel drive motor and the auger drive motor are connected in series but a separate line to the auger allows the
reel speed to change independently from the auger speed. Switches on the GSL are used to adjust the reel speed
which is displayed on the CDM display. The reel speed can be set by three methods;
• Reel Only (only reel speed changes)
• Reel On-the-Go (reel and auger speeds change)
• Reel to Ground (indexed)
NOTE: Adjusting the reel speed will result in a change to auger speed unless the auger speed has
been preset.
18. Auger speed not to exceed 320 rpm.
