6.6 –Deck Plates

Danger: Before repairing or adjusting any part of the corn head, engage the feeder house lift
cylinder safety stops, set the parking brake, turn off the combine engine and remove the
key and hang a warning sign on the operator’s platform. Failure to do so could result in
serious injury or death.

The deck plate opening on the Drago GT corn head is tapered with a larger opening at the rear of the row unit
as compared to the front. The deck plates are preset at the factory and should normally not require adjustment
for most field conditions. Adverse field conditions; however, may require adjustment. The row unit alignment
needs to be checked as described in Section 6.5 prior to adjusting deck plate clearance. Typical needs for
adjustment are small ears, large stalks, drought stressed crop, stalks not entering deck plates, or harvesting
specialty crops.

The factory settings for the deck plates are 7/8” (22mm) at the front and 1 1/16” (27mm) at the rear.

Note: The cams may be installed at different settings from the factory when comparing rows. This is necessary
to achieve the same deck plate opening on all row units due to manufacturing tolerances.

6.6.1 – Maximum Opening

The maximum deck plate opening is controlled by the
half-moon shaped cam (A) on top of the row unit
frame.

1) Maximum possible opening is 1 1/8”
(28mm) at the front, and 1 3/8” (35mm)
at the rear.
2) To adjust loosen socket head bolt (B) and
rotate the cam (A).
3) The half-moon cams have numbers laser
cut in them.
a. Larger Number = Larger deck plate
maximum opening.
b. Smaller Number = Smaller deck
plate maximum opening.

Checking Maximum Opening

Insert tool ST-7 (C) sideways in between the deck
plates at the rear of the opening. Ensure the text
“Max_R” is between the deck plates. Twist tool ST-7
(C) to expand the deck plates to their maximum
setting. The deck plates should not be able to be
manually opened any further.

Note: The deck plate maximum opening does not need
to be inspected on a regular basis. It requires
inspection only if damage to the system is suspected
or if conditions require changes to the maximum
opening.
