McCormick-Deering second W series – standard tractors W-6, W-9, WD-6 and WD-9: International four-cylinders with 27 to 37 kW, WD models with diesel engine, W models on kerosene or petrol
The second W series from McCormick-Deering comprises the standard tractors W-6, W-9, WD-6 and WD-9 from International Harvester, dating from the 1940s. The D suffix distinguishes the engine type: while the W-6 and W-9 ran on distillate, kerosene or petrol, the WD-6 and WD-9 were fitted with a diesel engine, as the register's fuel data also shows. All four models carry four-cylinder engines from International's own production and represent the last generation of classic standard tractors with a rigid front axle, before International Harvester increasingly turned to row-crop and later general-purpose designs.

The register lists 4 versions with 27.2 to 36.8 kW (35 to 49 hp) from four-cylinders with 4,059 to 5,482 cm³ displacement. Unladen weights range from 2,191 to 2,654 kg, lengths from 3,159 to 3,410 mm, widths from 1,600 to 1,924 mm, and heights from 2,080 to 2,305 mm; rated speeds lie between 1,450 and 1,500 rpm.
As standard tractors with an equal track width, the W series targeted large farms with a high need for draft power in tillage, harvesting and belt work, while the row-crop Farmall tractors built alongside them served the cultivation of growing row crops. The diesel variants WD-6 and WD-9 marked the brand's shift towards more economical diesel engines.
On these historic tractors, the condition of the cylinder head and cooling system, the tightness of the respective fuel system – diesel on the WD models, kerosene or petrol on the W models – wear on steering and clutch, and the condition of sheet metal and paintwork all matter. Spare parts today come mainly from specialist vintage-tractor parts dealers.
