c) Tension the belts until there is
approximately 1 1/2 inches of belt sag on
conventional Rake-Up and Swathmaster
pickups and SwathMaster Small Seed
pickups, and 2 inches of belt sag on
Rake-Up Small Seed pickups when
lifting midway between rollers. This
adjustment is shown in the Draper Belt
Adjustment For Conventional/Small Seed
Pickups.
d) Tighten 1/2-inch carrier bracket bolts.
NOTE:
1. When the pickup is mounted on the
combine, there should be visible sag in the
bottom side of the draper belt(s).
2. Some draper belts when new are very
tacky. Talcum or baby powder rubbed
into the belts may help to reduce the
tackiness. In addition, for the first few
hours of break-in, the belts may need to be
run looser than normal.
DO NOT OVER-TIGHTEN THE BELTS!
This can cause a number of problems:
1. Joining bolts can pull out of draper belts.
2. The center belts will slip on conventional
pickups.
3. The belts will crawl over the dividers.
4. The rollers or bearings could be damaged.
Any belts that fail from being over
tightened will not be covered under
warranty!
B) Belt Alignment–SwathMaster Small
Seed Pickups
If you are having trouble with the belts moving
sideways out of the pulleys and wearing the belt
edges, the following procedure should be
followed:
(a) First, check draper belt tension. An over
tensioned draper belt will tend to crawl
sideways more. If you are not sure, try
loosening the belt very slightly and then re-
evaluating.
