3. continued)
Bolt opening adjustment bars to deck at the hole corresponding to the draper row. For example if drapers
are to be connected at row E (from chart on previous page), move roller until hole (E) aligns with deck
mounting slot. Use a carpenter’s square to ensure roller is square to deck and tighten hardware.
NOTE: For access to bolt securing the
adjustment bar at cutterbar on L/H (moveable)
deck, remove retainer clips (G) and, if installed,
the front edge draper seals and clips (see page
48). Raise front of deck for access to bolt.
4. Cut excessive flap off of draper, leaving 3/8"
(10 mm) extending above the connector. Trim
the new ends at the front corners as shown on
page 21. This allows draper to fit properly
under front draper seal to prevent tearing of
front edge. Use the cut-offs as a guide for
trimming. Keep the cut-offs for use as a splice.
5. NOTE: Place connector tube so holes closest
to end of tube are at the cutterbar.
Connect draper with screw heads facing center
opening.
NOTE: To reduce the opening size after it has
been enlarged, a short section of draper
(available from your dealer) can be added to
increase draper length.
6. Slide bracket (C) away from outboard roller as
far as hand force allows. Check that draper V-
guide (E) is properly engaged in grooves at
rear of both rollers.
7. Tighten nut (B) to secure the position of
bracket (C).
8. Apply draper tension by turning bolt (A) clock-
wise until gap between idler spring coils is 1/16
inch (1.5 mm).
IMPORTANT: Do not collapse spring. The
spring maintains draper tension and prevents
over-tension. If spring is collapsed, damage to
draper and rollers may result from excessive
draper tension.
