Abstract

PURPOSE: To enable to perform gear shifting without stopping running of a tractor, by a method wherein 2 systems of transmission gears are mounted to a transmission route from an engine, and a gear is shifted by the use of the one transmission gear as driving is effected by the use of the other transmission gear.
CONSTITUTION: Two transmission mechanisms, having a synchromesh mechanism and the same structure as each other, are mounted to an output shaft 1 transmitting a power from an engine, and the two transmission mechanisms can be selected by means of clutches 25 and 27. When control of gear shifting is effected, the one clutch 27 is disengaged, a power transmission system on the side of said clutch is brought into a free state, and a power is transmitted to driving wheels through other clutch 25 and a power transmission mechanism on the side of the other clutch. With this, gear shifting is conducted, the clutch 27 is engaged upon completion of gear shifting control and simultaneously the clutch 25 is disengaged, and this enables to perform gear shifting without stopping running of a tractor.
