Model historyEdit

For Company history see
Main article: International Harvester

The McCormick-Deering O-6 was was based on the W-6 but the air intake and exhaust were lowered to give a completely smooth hood, optional headlights were mounted below the radiator, the seat and controls were mounted lower and farther to the rear, and smooth shielding covered the rear wheels and steering wheel, and side panels enclosed the engine so that there was nothing exposed to catch on low hanging branches and fruit.
