Case IH DC93

DC93 Rotary Disc Mower Conditioners Features

The Most Reliable Rotary Disc Cutterbed Anywhere

• 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 four models of DC2 rotary disc mowers
• Roll and flail conditioning options available on all models

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

Disc Modules

• 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

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
• 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 are standard on DC162, optional on DC102 and DC132
• Easily handle higher crop volume and faster ground speeds
• 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
