Cutterbar Deflectors
A two-piece cutterbar deflector is attached to the cutterbar just below the 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:

Removing Cutterbar Deflectors
The cutterbar deflectors are used with roll conditioners only.
DANGER
To avoid bodily injury or death from unexpected start-up or fall of a raised machine, stop engine, remove key, and
engage lift cylinder lock-out valves before going under machine for any reason.

9.
If the conditioner is going to be completely removed,
reinstall bolt (B) through the rock guard and secure it with
an M12 washer and locking nut. Torque hardware to 68 Nm
(50 lbf·ft). Store the deflectors and hardware in a
safe place.
10. If the cutterbar is being replaced, install the deflectors on the new cutterbar. For instructions, refer to

Removing the deflector helps feed dirt/rocks through the header and prevents debris buildup, wear and damage
from rocks.
