INTRODUCTION
KEY OPERATION POINTS
• Cutting performance and distribution are best when cutter is level from side to side. Mower front to rear
pitch should be 1” or less.
• In extra heavy material, rear chains will allow better discharge and better distribution than solid rear
deflectors or bands.
• Never operate the Flexwing below full PTO speed of 540 or 1000 rpm.
• For good distribution, the distribution baffles must be used.
• Make sure PTO driveline slip clutches are not frozen and are properly adjusted.
• To reduce uneven grass cutting and streaking.
- make sure tractor rear tire spacing is a minimum of 60” between the inside of the tires.
- make sure blades are not bent and are in good condition.
- reduce ground speed to allow more cutting time.
• Corn should be cut at 5 to 6 mph. If full PTO rpm cannot be maintained, use one lower gear.
• Corn yield of 180 bu. per acre will require a minimum of 105 PTO horsepower to shred at 5 to 6 mph. To
maintain the suggested 5 to 6 mph ground speed when cutter is equipped with deck rings, a minimum PTO
horsepower of 115 is recommended.
• If Tractor engine is lugging down, shift tractor to a lower gear
• ALWAYS OPERATE WITH THE WING HYDRAULIC CYLINDER CONTROL VALVES IN A FLOAT
POSITION.
• For maximum performance and service life, Always use Genuine Rhino replacement parts
Operating Noise Level/Sound Pressure
The sound levels at the operator's ear from the attached machine (rotary cutter) are at least 10 dB(A) below the
levels from typical Agricultural tractors used to power and transport this machine. Therefore, the Noise
emission values given by the OEM of the Agricultural tractor used to power and transport this machine would
be valid when this machine is attached to and operated by that Agricultural tractor in all OEM recommended
applications.
