Henry Ford began making tractors under the name Fordson, shortened from Ford & Son Inc., in 1917. Fordson stopped production in the U.S. after 1928, but continued making tractors in England. The company produced the Ford 4000 tractor from 1965 to 1975. The agricultural tractor was available in both a gasoline model and a diesel model.
The Ford 4000 gasoline model offered a three-cylinder engine with a displacement of 192 cubic inches. The compression ratio was 8 to 1 and the engine was rated at 2,200 rpm. The Ford 4000 diesel model offered a three-cylinder engine with a displacement of 201 cubic inches. The compression ratio was 16.5 to 1 and the engine was rated at 2,200 rpm.
The Ford 4000 tractor featured two transmission options. One option was a dual range transmission with eight forward and two reverse gears and a 3.3-gallon oil capacity. With this option, the tractor had to be stopped to shift gears. The other option was a Select-O-Speed transmission with 10 forward and two reverse gears that could be shifted while the tractor was in motion. The transmission had a 3.075-gallon oil capacity. The two-wheel drive tractor featured mechanical, self-energizing, wet-disc brakes and a heavy-duty dry-disc clutch and offered hydraulic powered steering.
