Chapter 4: Changing Conditioner

There are several ways that the conditioner can be configured, depending on your particular machine.
The R1 Series Rotary Disc Header can be operated either with no conditioner, with a polyurethane roll conditioner, or with
a steel roll conditioner. If the rotary disc header is not conditioner-equipped, a shield must be installed.
NOTE:
These instructions apply to all conditioners. Exceptions are identified where applicable.
If the header was shipped with the desired conditioner configuration, proceed to
Windrower, page 35.
If the header was shipped without a conditioner, and you want to install one, proceed to
