MacDon PW8 Pick-Up Header - Manual (Page 64)

OPERATION
Adjusting Draper Speed
Draper speed is determined by measuring the rpm of the
aft roller on the rear pick-up deck.
1. Check the roller rpm (A) with a handheld tachometer,
and adjust with the reel speed control in the combine.
NOTE: Some combines are equipped with a speed
sensor (B) that indicates the roller rpm in the
combine cab.

3.12.2 Auger
Auger Speed
The header is supplied with an auger drive sprocket to match your combine. The auger is driven by a direct
connection to the feeder house, and auger speed depends on the feeder house speed. In certain crops, a higher
or slower auger speed may be desired. Contact your Dealer for available sprocket options.
Refer to Section: Auger Drive Sprockets, page 117 for instructions on changing the sprocket.
Auger Position
The auger position is critical for a smooth, high capacity flow of crop into the feeder house. It is factory set for normal
crop conditions but may require adjustment for different crops and conditions.
The auger must rotate freely without touching the auger pan or stripper bars, and the position should be checked
prior to operating the pick-up.
The clearance (A) between the auger flighting (B) and
pan (C) should be 3/16–7/16 in. (5–11 mm).
