造。 The transmission system for the steerable front wheels 1, 1 is a clutch type that switches between a standard drive state in which power is transmitted at a drive speed approximately equal to the rear wheel drive speed, and an increased speed drive state in which power is transmitted at a drive speed greater than the rear wheel drive speed. A traveling transmission structure for a work vehicle equipped with a front wheel transmission 10, comprising:
The clutch 20 of the standard drive system in the front wheel transmission 10 is configured as an articulating clutch, and the clutch 18 of the speed-increasing drive system is configured as a tapered cone type friction clutch. A travel transmission structure for a work vehicle configured to be selectively engaged and operated by reverse operation.
