The Case IH WD 1903 Series II is a self-propelled swather with a six-cylinder Case IH FPT engine. The engine has 6,700.7 cm³, a turbocharger with charge air cooler and meets Tier 3. Ritchie Specs gives 190 hp, 199 hp maximum.
The two-speed hydrostatic transmission allows up to 11 mph in the field and up to 18 mph on the road. The wheelbase is 3,485.1 mm (137.21 in), the weight without header 12,301.8 lb and the length without header 16.59 ft. The tank holds 120 gallons. The cab is suspended.
Compared with the WD 1203 Series II with four cylinders and 126 hp the output rises clearly, and at 11 mph field speed the 1903 is slightly faster than the 1203 at 10.3 mph. The types WD 1904 and WD 2104 are later developments of the same engine size of 6,700.7 cm³.
Case IH Swather: WD-series windrowers from WD 1203 to WDX 2302 with Case IH FPT engines, 4,502 to 7,500 cm³ displacement, four- to six-cylinder
Case IH builds self-propelled windrowers (swathers) in the WD range, which cut grain, grass and oilseeds and lay them into windrows before a combine picks them up. The WD designation stands for Windrower Drive, the four-digit number gives the machine size; suffixes such as Series II or Tier 3 Canada mark model revisions or the emissions stage certified for the Canadian market, while WDX marks the newest generation. The machines are powered by Case IH FPT engines, the product of CNH Industrial's in-house engine manufacturing (Fiat Powertrain Technologies).

The register lists here 12 versions from four- to six-cylinder engines of 4,502 to 7,500 cm³ displacement.
Windrowers such as the WD range are chiefly used in North America, where canola, lentils and other oilseeds are wilted and windrowed ahead of threshing to better control harvest timing and grain moisture; Case IH competes here mainly with John Deere, New Holland and MacDon.
For a used purchase, check the condition of the cutting mechanism and knife bar, the function of the windrow canvas or auger, the tightness of the hydraulics for header tilt and ground following, and the operating hours and service condition of the FPT engine; spare parts run through the Case IH dealer network. On the Tier 3 Canada versions, it is also worth checking the exhaust aftertreatment components, whose wear varies considerably with service history.
