DC133 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
