5.7 Checking and Adjusting Draper Seal
Maintain the deck height such that the draper runs just below the cutterbar.
IMPORTANT:
New factory installed drapers are pressure and heat
checked at the factory. The gap between the draper (A)
and cutterbar (B) is set to 1–3 mm (1/32–1/8 in.). To
prevent material from entering the drapers and cutterbar,
you may need to decrease the deck clearance to 0 mm
(0 in.) after an initial break-in period of approximately
50 hours.
1. Check deck height. Draper (A) should run just below
cutterbar (B) with a gap of 1–3 mm (1/32–1/8 in.)
between the top of deck front track and cutterbar.
• If deck height is acceptable, skip the remaining
steps and proceed to
• If deck height is
NOT
acceptable, adjust seal as
described in the following steps:

NOTE:
Take measurement at deck supports (A) with the
header in working position. There are between two
and
fi
ve supports per deck depending on header size.
