Kind Code:

Abstract:
To reduce a shift shock when switching from 2-motor travel to 1-motor travel in a work vehicle including a hydrostatic transmission.SOLUTION: When a vehicle speed increases and reaches a prescribed switching threshold value, a controller decreases the capacity of a first travel motor and controls a flow control device so as to offset an excess portion of the flow rate in a hydraulic circuit corresponding to the decrease in the capacity of the first travel motor. After the vehicle speed reaches the switching threshold value, the controller performs switching control for switching a clutch from an engaged state to a disengaged state.SELECTED DRAWING: Figure 11
