3.11 Cutterbar Deflectors
A two-piece cutterbar deflector is attached to the cutterbar just below the header
’
s conditioner rolls. Deflectors provide
improved feeding into the conditioner rolls and prevent heavy crop with long stems from feeding under the rolls.
Cutterbar deflectors may not be well-suited for some crop and field conditions. Refer to the following table:
Table 3.2 Conditions for Using Cutterbar Deflectors
Crop/Field Condition
Use Deflector
Average crop/normal field conditions No
Long stemmed and heavy/normal field conditions
Yes
Long stemmed and heavy/sandy soil
No
Long stemmed and heavy/gopher mounds or rocks
(refer to note below table)
No
NOTE:
Removing the deflector helps feed dirt/rocks through the header and prevents debris build up, wear and damage
from rocks.
