ABSTRACT:
A hydraulic drive vehicle includes a bypass valve for fluidly connecting or disconnecting a pump/second-motor line and a second-motor/first-motor line, and set a capacity of a first hydraulic motor to a standard capacity which makes a peripheral speed of a first wheel driven by the first hydraulic motor equal to a peripheral speed of a second wheel driven by a second hydraulic motor when the bypass valve fluidly disconnects the two lines and set the capacity of the first hydraulic motor to a first capacity smaller than the standard capacity when the bypass valve fluidly connects the two lines. The present invention makes it possible to widen a variable range in which a traveling speed of the vehicle could be changed.
