INTRODUCTION
Your FN20 NITRO is a super-duty Cutter/Shredder designed primarily for weed and grass control, brush up to
4-1/2" diameter, and shredding row crops such as cotton and corn stalks. With proper maintenance as
described in this manual, your Cutter will provide you with years of dependable service with a minimum of
repairs.
It is recommended that all operators of this implement read this manual or be instructed of its contents as to
safety, proper operation, and maintenance before beginning operation.
Your FN20 NITRO has been assembled for operation with a specific tractor PTO input speed, either 540 or
1000 RPM. Should you desire to change PTO input speed, contact your local Rhino dealer who will assist you
in performing the necessary modifications. A different Driveline and gearboxes or reverse gear positions are
required. This machine is designed for use with tractors rated 80 HP (60kW) to 170 HP (127kW).
When ordering parts for the Gearboxes and the Drivelines, be sure to specify the PTO speed (540 or 1000
RPM) and the serial number. The serial number is located outside of the right Tongue attaching Plate on the
center Mainframe section.
Chain Guards are extra equipment. Deflectors, Driveline Integral Shields, and Gearbox Shields are standard
equipment and to be used at all times.
To place the warranty into effect, fill out the warranty card in full, giving all the requested information, and mail
