Rotary Disc Mower Conditioners 

You'll grow to depend on the most reliable rotary disc cutterbed anywhere — one that survives the toughest cutting conditions with minimum maintenance.

Case IH DC disc mower conditioners feature:

• A modular cutterbar design with superior crop flow, resulting in less streaking
• A heavy-duty frame and rugged canopy that have a cantilevered design for smooth crop flow across the cutterbar
• Shock hubs, now standard on all models
• Roll and flail conditioning options available on all models

Disc Modules

Independent disc modules for easy service, repair

• Bearings, gears and lubricant for each disc module are individually sealed — damage to one module does not spread to another
• Modular design ensures complete gear lubrication, even when cutting on slopes
• Two heavy-duty knives on each disc spin at 3000 rpm to slice through heavy crops
• Knives are reversible for twice the cutting life
• One bolt per knife allows for quick flipping or replacing of knives from the front of the cutterbed — without raising the header
• The steep profile design lifts the crop directly into conditioning rolls
• Discs are austempered for extra hardness and durability in punishing conditions

Shock Hubs

Shock hubs are now standard on all four models of DC Series rotary disc mower conditioners. The system replaces the drive hub of discs with a shock hub, making in-field repairs fast and easy.

• Helps prevent time-robbing, expensive field failures when an obstruction is encountered
• Shock hub “takes the blow” from collisions with rocks and debris
• Protects internal components of the cutterbed

Case IH rotary disc mower conditioners let you bale or chop sooner.

• Spiral steel-on-steel or rubber-on-rubber conditioning rolls provide fast drydown
• Saves time in the field by clearing slugs automatically
• Allows for easy changes in conditioning intensity

All Case IH mower conditioners allow for custom-built windrows or swaths.

• Spread the crop out in a wide, fast-drying swath
• Form the crop into a narrow, fluffy windrow that’s ready for baling or chopping
• All adjustments to the swathboard, windrow shields and fluffing baffle can be made without tools

Conditioning Rolls

• Torsion-bar design
• Applies equal force to the upper conditioning roll arms
• Provides uniform conditioning, regardless of crop thickness
• Intermeshing spiral conditioning rolls have superior crimping and crushing action for faster drydown
• Rubber-on-rubber conditioning rolls are standard on DC92, DC102 and DC132
• Rugged steel-on-steel rolls
• Standard on DC162, optional on DC102 and DC132
• Easily handle higher crop volume and faster ground speeds
• Delivers longer life
• No-tools crank adjustment
• Changing conditioning roll pressure is quick and easy for greater productivity
• The system releases pressure when the upper roll reaches its maximum opening 

Flail Conditioning

Now available with all models.

• Uses tapered flails to pick up crop and rub it together and against the conditioning hood
• Faster drydown because the waxy layer on the stems is removed and moisture is released quickly

Straight flails release crop more easily than competitive systems

• Produce a more uniform crop mat that lays on top of the stubble
• Results in better air circulation in the windrow and more thorough drying
