OPERATION
DELIVERY OPENING WIDTH
Adjust delivery opening width:
Decks can be slid inwards to adjust opening size without cutting or extending the drapers
All headers are supplied with a long draper which may be cut to provide a wider opening. By cutting both
drapers, opening can be increased by 19” (480 mm). If reducing the opening size after it has been enlarged, a
short section of draper (available from your dealer) can be added to increase draper length.
NOTE: To avoid damage to draper and/or draper tension
mechanism, do not use drapers that are different in
length from those specified.
For adjusting opening size without cutting drapers,
go to step 8:
To cut or extend draper:
1. Release draper tension by turning bolt (D) counter-
clockwise until bolt begins to turn out of backsheet.
2. Remove screws from draper connector slat.
3. Use the following chart to determine which opening
size and row of holes are required for the desired
application.
NOTE: Recommended starting point is with decks shifted in, column (Y) for rows I and III.
For row II start at 45.4” (1155 mm) for specialty crops and 42.1” (1070 mm) or less for cereal crops.
