MacDon FD75 OM - Manual (Page 163)

OPERATION
The flow control (A) has values 0–9 on the barrel, that
line up with a notch on the hydraulic compartment cover
to indicate the draper speed. The draper speed control is
factory-set to ‘6’ which should satisfy normal crop feeding.
To change the draper speed, shut down the combine, and
adjust the control accordingly by simply rotating the dial.
Refer to the following for recommended draper speed
settings:
• 4.6.2 Header Settings, page 47 , or
• 4.6.3 Optimizing Header for Straight Combining Canola,
page 48
NOTE:
Insufficient draper speed may be caused by low
relief pressure.
See your MacDon dealer for
checking and adjusting relief pressure in the
CA25 hydraulics.
Figure 4.223: Speed Control
Adjusting Feed Draper Speed
The feed draper moves the cut crop from the side drapers into the adapter feed auger.
The adapter feed draper (A) is driven by a hydraulic motor
from a pump which is powered by the combine feeder
house drive through a gearbox on the adapter.
The feed draper speed is fixed to the combine feeder house
speed and cannot be independently adjusted.
