Revision D
9.11.7 Draper Speed
a. The speed of the header/side drapers (A) is
adjusted at the flow control (B) on the combine
adapter.
b. Turn knob (B) “two turns from closed”, and then
adjust draper speed to achieve good feeding of
crop onto adapter draper. Excessive draper
speed will reduce draper life.
NOTE
Three turns open produces full draper
speed.
NOTE
If sufficient draper speed cannot be
achieved, a possible cause is low relief
pressure. Refer to the Technical
Service Manual for checking and
adjusting relief pressure.
c. The adapter feed draper (C) is driven by the
adapter mounted hydraulic pump. The speed is
factory-set, and cannot be adjusted.
