MacDon FlexDraper FD1 Series, Operator'S Manual, Page: 97 / 510

OPERATION
• Crop being pushed down by the tine tubes
The following conditions might result if the reel is set too high:
• Cutterbar plugging
• Crop lodging and being left uncut
• Grain stalks dropping ahead of cutterbar
Refer to
3.6.2 Header Settings, page 43
to determine recommended reel heights for speci fi c crops and
crop conditions.
IMPORTANT:
Maintain adequate clearance to prevent fi ngers contacting the knife or the ground. Refer to
5.13.1 Reel Clearance
to Cutterbar, page 404
.
Manually Checking Voltage Range
The output voltage range of the auto reel height sensor can be checked from inside the combine. For instructions
refer to the combine operator’s manual. To check the voltage range of the auto reel height sensor manually, follow
these steps:
CAUTION
Check to be sure all bystanders have cleared the area.
IMPORTANT:
To measure the output voltage of the reel height sensor, the combine needs to be turned ON and supplying power
to the sensor. Always engage the combine parking brake to and stay away from the reel.
1. Engage the combine parking brake.
2. Lower the reel fully.
3. Use a voltmeter to measure the voltage between the
ground (Pin 2 wire) and the signal (Pin 3 wire) at the
reel height sensor (A). Ensure the voltage is within the
Y voltage range. Refer to
3.11 Reel Height Sensor
Voltage Limits, page 80
.
4. If voltage is outside the speci fi ed range, refer to
Adjusting Reel Height Sensor, page 80
.
