Abstract
A change-speed construction for a propelling system of a work vehicle. The construction has a neutral return mechanism for causing a stepless transmission to return to the neutral in response to disengagement of a main propelling transmission clutch. Then, when the clutch is engaged again to resume vehicle run after a temporary stop for e.g. replenishment of materials to be worked, the vehicle does not make a sudden start.
