Preparing the Header

INSTALL HEADER SIDE DRAPERS

NOTE: For 963 Headers only – For delivery
openings of 41.7” (1060 mm) and smaller, before
installing draper, install draper supports (S) at

carriage head bolts and flange nuts. For larger
openings, remove supports (S), if installed.

1. Connect side drapers according to your Header

Set-Up Instructions or Operator's Manual.

IMPORTANT: Cut off any excess flap only after

drapers have been connected and tensioned and

overlap at sides of feed draper deck has been

checked.

2. In some cases, actual opening size will be varied

by re-positioning deck on one side to properly

overlap and align with feed draper. See plasticized

Set-Up card provided.
