Better suspension. Better performance.

The smooth ride from the independent rear axle suspension lets you drive faster, increasing cutting speed, and allows you to get more done in a day. Ideal for high-speed operating conditions – as when running a disc header – this suspension system also provides added protection for your windrower by reducing shock load to the chassis. Single Cast Tail Wheel reduces dirt build up in muddy conditions improving performance.

Cutting taken to a science

Perfect for cutting on terraces or borders, the Case IH WD1903 and WD2303 feature industry-exclusive independent lift arm flotation for the header. Adjustable from the cab, separate hydraulic systems for the left- and right-sides of the machine effectively work as a tilt allowing you to tailor the cut to the terrain on the go.

WD1903 and WD2303 incorporate a new Multi-Function Handle. The new handle is similar in shape and size but offers the following key benefits:
• Ergonomically enhanced for increased operator productivity and comfort.
• Resume button for header raise and lower

Optimized comfort for those long days in the fields

Here’s a perfect fit: the adjustable air suspension seat and ride suspension sensor adjusts to suit any operator and provides greater comfort and optimal control. Optional cab suspension and the suspended rear axle promise to provide a smooth ride over the roughest terrain, leaving you less fatigued at the day’s end.

The definition of heavy-duty

Two heavy-duty knives on each disc on the rotary disc headers spin at 2,500 rpm to slice through heavy, tangled crops. Knives are reversible for twice the cutting life. Not only do the RD 3 series rotary discs feature wider discs than the previous RD 2 series, but they are also equipped with even stronger components such as wider gears and larger cross shafts that are lubed to prevent wear. Discs are austempered for extra hardness and durability in punishing conditions and the protective liner in the hood helps reduce rock damage. Modular cutterbar design features self-contained oil reservoirs with individual dipsticks which make fluid checks easy, eliminate cross contamination across the cutter bar and ensure maximum lubrication on inclines.

Refined with intuituve design

The full-length auger provides optimal feeding from the cutterbar into the conditioning rolls. Engineered with a positive feed design, the auger more effectively moves crop toward the center of the conditioning rolls for more even windrow formation. These innovative CaseIH headers are engineered to combine greater productivity with reduced power consumption.

HDX sickle bar headers

For quality hay-harvesting results, team an HDX sicklebar header with one of the WD 3 self-propelled windrowers. Treat your hay to the smooth cutting and gentle handling of the Case IH sicklebar headers. HDX sicklebar headers use the counter-stroking action of dual sickles to shear crop cleanly, while the unique floating auger keeps the crop moving smoothly to the conditioning rolls.

Bolt-on knife sections

Bolt-on knife sections are standard on all sicklebar models for easy field replacement if necessary. These over-serrated knife sections provide long life and a cleaner cut in most crop conditions. Double heat-treated range guards offer long life in tough conditions and superior resistance to rock damage.
