The most options to fit your operation

Case IH continues the tradition of giving you the most options to fit your operation. You can choose among three models.


  • Cutting width  — 16 ft. 1 in. (4.9 m)  
  • Compatible — WD1903 and WD2303
    • Rubber-on-rubber conditioning rolls  
    • Steel-on-steel conditioning rolls
    • Flail conditioner (For grass like crops)
    • Hi-contact rolls for legume-type crops in low-humidity climates
    • Conditioning rolls are mounted in "modules" that are easily removed and exchanged to suit different crops and conditions throughout the season
  • Complete removal of the conditioning roll module allows for cutting without conditioning, if desired


  • Perfect for large-scale commercial growers  — delivers unbeatable speed
  • Industry-leading cutting width  — 19.3 ft. (5.9 m) 
  • Compatible  — WD2303 
  • Full-length auger eliminates the need for co-rotating discs and increases cutoff performance


Rugged and easy service, repair or replacement

Rugged, independent disc modules offer many advantages:

  • Easy service , repair or replacement
  • Individually sealed bearings , gears and lubricant – damage or contamination to one disc doesn't spread to another
  • Complete gear lubrication , even when cutting on slopes or at an angle
  • Austempered discs for extra hardness and durability in punishing conditions
  • A protective liner in the hood helps reduce rock damage
  • Heavy-duty gears and cross shafts


Standard on all rotary disc header models


  • Protects key disc module drive components when a disc encounters a field obstacle
  • Easier in-field repairs
  • Dramatically reduces downtime
  • Lower replacement-part cost


Two knives on each disc feature:

  • One-bolt knives that are reversible for twice the cutting life
  • A knife speed of 187 mph (301 kph)
  • A cutterbar angle that  adjusts hydraulically from 2–10 degrees below horizontal using the in-cab switch



Intermeshing, spiral, rubber-on-rubber, steel-on-steel or Hi-Contact conditioning rolls or flail

Rugged construction

  • RD163 and RD193  — equipped with intermeshing, spiral, rubber-on-rubber, steel-on-steel or Hi-Contact conditioning rolls or flail
  • Conditioning rolls provide 102-in. (2.6-m)-wide superior crimping action
    • Results in faster drydown in both light and heavy crops
  • Rugged construction allows rolls to process both  higher crop volume and faster ground speeds typical of a rotary disc header
  • Chevron conditioning rolls evenly distribute the crop across the whole windrow, eliminating more material on the sides of the windrow
