ABSTRACT:
Drive mechanism for a four-wheel-drive tractor, comprising a pair of input shafts in double tube construction with one fitted to nest in the other, main gearing shaft assembly, differential gearing, front-wheel-drive-shaft assembly, gearing wheels provided in both frontal and rear portions of the front-wheel-drive-shaft assembly, a power-take-off shaft and a drive shaft-assembly. Driving power taken out from the gearing wheel provided in front portion of the front-wheel-drive-shaft assembly is transmitted to front wheels via a transmission shaft with a mating gear, disposed at an underbelly portion of the tractor. The drive assembly is provided above the differential gearing. With this construction, the front-wheel-drive-shaft can be made short, sufficient empty space height can be provided in the underbelly portion of the tractor, and the transmission housing can be minimized.
