215575 80 Revision B
The following operating speed is suggested:
Front and Rear Deck Aft Roller: 51 rpm per 1.6 km/h (1 mph) of combine ground speed.
Example: For combining at 8 km/h (5 mph), the rear roller shaft should run at 51 x (8/1.6) = 255 rpm
(51 x 5 mph = 255 rpm).
Adjusting Draper Speed
Draper speed is determined by measuring the speed in rpm of the aft roller on the rear pick-up deck.

1. Check aft roller (A) rpm with a handheld tachometer. This
setting can be adjusted with the reel speed control in the
combine.
NOTE:
Some combines are equipped with a speed sensor (for
example, speed sensor [B]) which displays the
roller’s speed.
3.12.2 Auger Operation
The performance of the pick-up header’s auger depends on the output speed of the combine’s feeder house, its position
and float settings, and the presence of certain options such as stripper plates.
Auger Speed
The header is equipped with an auger drive sprocket specific to the make and model of the combine. The auger is driven
by a chain directly connected to the feeder house sprocket, so that the speed of the auger depends on the speed of the
combine’s feeder house. You can adjust auger speeds from the combine cab to suit crop conditions. Contact your Dealer to
learn about different sprocket options.
Refer to Auger Drive Sprockets, page 245 for instructions on changing the sprocket.
Checking Auger Position
The position of the auger is critical for ensuring the smooth flow of crop into the feeder house. The position is factory-set
for normal crop conditions, but can be adjusted to suit different crops and operating conditions. Check the position of the
