Checking And Adjusting Snout Height - MacDon C Series Unloading And Assembly Instructions

5.2 Checking and Adjusting Snout Height

The snouts must be positioned properly so that they can work effectively.
1. With the header resting on 10 x 10 cm (4 x 4 in.) blocks,
and the header angle set at 23°, tip (A) of each center snout
should be just off the ground. Gently press each tip down.
With minimal pressure, you should be able to force the tips
to touch the ground.
2. If necessary, adjust the position of each center snout as
follows:
• Make coarse adjustments by changing the position of
front cross bolt (A). Ensure the support adjustment bolt
head faces the gathering chain on the end snouts to
avoid contact.
• Ensure cross bolt (A) is lined up in the correct hole. The
front holes on the fixed bracket should use the front
holes on the arm and the rear holes on the fixed bracket
should use the rear holes on the arm.
• Ensure cross bolt (A) is slightly loose to allow snout
support arm (B) to pivot up and down.
• Fine tune the position of the snout by adjusting the rear
eye bolt (C).
3. Set the end snouts 13–25 mm (1/2–1 in.) higher than the
rest of the snouts to prevent them from catching crop and
debris on the ground if the combine is turned while the
header is on the ground.
