JI Case Crossmotor-Baureihe
7 models in this series
J.I. Case Crossmotor series (1915–1929) – the tractors with transversely mounted engine from Racine: 8-18 to 40-72, the numbers as drawbar and belt power in hp, four-cylinders of 3.9 to 20.2 litres, kerosene and petrol
The Crossmotor tractors are the machines with which J.I. Case of Racine, Wisconsin, moved from steam-engine building into tractor building: from 1915 the company built tractors whose four-cylinder engine lay in the frame transversely to the direction of travel – Crossmotor – which simplified the drive to belt pulley and gearbox, and kept the layout until 1929, when the models C and L with longitudinal engine followed. The type logic follows the convention of the time: the two numbers give drawbar and belt power in hp – 8-18 eight hp at the drawbar and eighteen at the belt pulley, 10-18, 12-20, 15-27, 18-32, 22-40 and 25-45 the mid-range, 40-72 the giant of the range with a four-cylinder of 20.2 litres built in only a few units. The engines ran on kerosene and were started on petrol, at rated speeds below 1,000 rpm.

The register lists 7 versions with 13.4 to 53.7 kW from four-cylinders of 3,866 to 20,181 cm³, unladen weights from 1,710 to 9,616 kg, lengths from 2,769 to 5,080 mm, widths from 1,473 to 2,667 mm and heights from 1,410 to 2,794 mm.
The Crossmotor models are the most sought-after Case collectors' pieces: the 40-72 was the most powerful tractor of the Nebraska tests of its time, the 12-20 and 15-27 the best sellers with which Case belonged to the three big American makers in the 1920s.
Used, they are museum pieces: completeness, originality of engine, carburettor and magneto, the condition of the steel wheels or conversion to rubber and provenance count; parts are reproduced.
